Résumé :

Callosobruchus spp. are global serious pests of pulses. Therefore, two studies were carried out to determine their distribution in three ecological zones of the Sindh, Pakistan along with their damage potential to major pulses. Survey was conducted from Zone-one (Ghotki, Sukkur and Larkana districts), Zone-two (Hyderabad, Mirpur Khas and Shaheed Benazirabad districts) and Zone-three (Karachi district) during March – April 2020. Grain samples of main pulses i.e., chickpea (channa), field pea (matar), cowpea (lobia), green lentil (moong) and daal channa were collected from three locations of each district and brought to Stored Grain Research Laboratory, Department of Entomology, Faculty of Crop Protection, Sindh Agriculture University, Tandojam for further examination. Three pulse beetle species i.e., C. maculatus, C. chinensis and C. analis were identified from the collected pulse samples as the highest populations of adults, eggs, grubs and pupae was recorded from moong, followed by lobia and gram. No population of pulse beetle was recorded from daal channa and matar. Callosobruchus maculatus was the most dominant species at all sampling as higher beetle populations were recorded from Mirpur Khas and Sukkur districts. Therefore, both these strains were further evaluated for their feeding preference and weight loss assessment on various pulses i.e., gram (chickpea), lobia (cowpea), moong (green gram) and daal channa (yellow lentil) in no-choice under laboratory conditions. C. maculatus showed a significant feeding preference among pulses with lobia and gram being the most preferred, whereas daal channa was the least preferred, hence suffered highest and lowest weight loss, respectively. Therefore, proper storage and quarantine measures are suggested to be taken in the transportation and storage of pulses to restrict the spread and damage of pulse beetles.

Résumé :

Aim: To assess the bioefficacy of plant oils against pulse beetle, Callosobruchus maculatus (F.) in green gram through wooden cube impregnation. Methodology: Bioefficacy of plant oils viz; clove, sweet flag, eucalyptus, orange, cedar wood and neem at two doses, i.e., 0.5 ml and 1.0 ml dispensed through a small wooden cube was assessed against the pulse beetle in green gram. The oils except neem are essential oils. A wooden cube impregnated with plant oil was placed over the grain surface and ten pairs of adult insects were released into each treatment. Data on oviposition, adult emergence and grain damage was recorded in each treatment. Insect mortality due to fumigant effect of plant oil at 0.5 ml per cube was also observed. Results: There was no oviposition by pulse beetles in clove, sweet flag, and eucalyptus oil treatments at 0.5 ml against the untreated control which recorded 14 eggs/100 grains. Consequently, no population buildup was observed in clove, sweet flag, eucalyptus and orange oil treatments after 120 days. A total of 2313.33 adults emerged from the untreated green gram inflicting 46.67 percent grain damage. In fumigant toxicity test, hundred per cent mortality of pulse beetle adults was observed with orange oil in 48 hr of treatment and with eucalyptus oil in 72 hr at 0.5 ml. The results indicated that the plant oils showed strong oviposition deterrence as well as insecticidal activity against the pulse beetle. Thus, application of essential oils through a wooden cube was found highly effective to keep away the pulse beetles. Interpretation: Essential oils of clove, sweet flag, eucalyptus and orange when applied through wooden cube impregnation at a dose as low as 0.5 ml showed strong oviposition deterrence and insecticidal activity against pulse beetle. The insecticidal activity of oils can be attributed to the fumigant action and can be used effectively to prevent pulse beetle infestation in grain legumes.

Résumé :

Pulse beetles, Callosobruchus chinensis and Callosobruchus maculatus, are essential pests of cowpea, gram, soybean and pulses. Application of synthetic insecticides against the pulse beetle has led to insect resistance; insecticide residues on grains affect human health and the environment. Essential oils (EOs) are the best alternatives to synthetics due to their safety to the environment and health. The main objective of the investigation was to study the chemical composition and insecticidal activities of EOs, their combinations and compounds against the pulse beetle under laboratory. Neo-isomenthol, carvone and β-ocimene are the significant components of tested oils using GC-MS. Mentha spicata showed promising fumigant toxicity against C. chinensis (LC50 = 0.94 µL/mL) and was followed by M. piperita (LC50 = 0.98 µL/mL), whereas M. piperita (LC50 = 0.92 µL/mL) against C. maculatus. A combination of Tagetes minuta + M. piperita showed more toxicity against C. chinensis after 48 h (LC50 = 0.87 µL/mL) than T. minuta + M. spicata (LC50 = 1.07 µL/mL). L-Carvone showed fumigant toxicity against C. chinensis after 48 h (LC50 = 1.19 µL/mL). Binary mixtures of T. minuta +M. piperita and M. spicata showed promising toxicity and synergistic activity. EOs also exhibited repellence and ovipositional inhibition. The application of M. piperita can be recommended for the control of the pulse beetle.

Résumé :

The susceptibility of different stored pulses infested by Callosobruchus chinensis L. (Coleoptera: Bruchidae) was observed in three varieties of stored pulses i.e. gram (Cicer arietnum L.), pea (Pisum sativum L.) and mung (Vigna radiata L.) during April, 2017 to May, 2018. The longest incubation-, larval- and pupal period of pulse beetle were in gram 5.4 ± 0.29, 12.6 ± 0.25, 5.5 ± 0.32 days, respectively and the shortest were in mung 4.6 ± 0.25, 11.3 ± 0.28, 4.2 ± 0.19 days, respectively. The shortest developmental period of pulse beetle was 20.1 ± 0.46 days in mung. The incubation-, larval-, pupal- and total developmental period of pulse beetle varied significantly between the pulse beetle grown in gram and mung (p < 0.05). The highest longevity and fecundity were in gram, 8.2 ± 0.33 days and 70.2 ± 7.53, respectively. The fecundity did not vary significantly in different stored pulses (p > 0.05). The longevity and number of adults emerged varied significantly (p < 0.05) between the gram and pea. The number of male emerged did not vary significantly (p > 0.05) between the different stored pulses and the number of female emerged varied significantly (p < 0.05) between gram and pea, pea and mung. The experiment revealed that pulse beetle preferred smooth coated and large size seeds to oviposit. Pea was found to be most resistant to attack by C. chinensis L. whereas mung was more susceptible than gram and pea. Dhaka Univ. J. Biol. Sci. 29(1): 19-25, 2020 (January)

Résumé :

The pulse beetle is a significant issue for the stored pulses. The adoption of resistant sources is a dependable, environmentally friendly prerequisite for sustainable grain protection, even though chemical management is still the most efficient method of controlling pulse beetles at large-scale storage. The impact of mung bean genotypes against pulse beetles (Callosobruchus chinensis) in stored grain was conducted under laboratory conditions in the Department of Agricultural Entomology, Ranchi Agriculture College, Birsa Agricultural University Kanke, Ranchi, from September to October 2018. The experiment was laid out in completely randomized design under the laboratory conditions. The results of the studies carried out on 52 genotypes of mung bean seed. the genotypes (SML 1829, VGG 16-058, IPM 2-14, KM 2355, SML 669, VGG 16-036, IPM 512-1, MH 1320 and Pusa Vishal), (IPM 2-14, HUM 16, SML 668 and KM 2355), (HUM 16, SML 668, IPM 2-14, MH 421, COGG 13-19, KM 2355, SML 1829, SML 1082, COGG 13-39, MH 13-20, VGG 16-058, VMS 13-12, SVM 61-61 and SML 669) and (IPM 2-14 and HUM 16) were performed best against C. chinensis on the basis of number of eggs laid, adult emergence, per cent grain weight loss and per cent seed germination, respectively.

Résumé :

The insect pests cause substantial loss of grains in the field and during storage of food grains that worth millions of rupees. Hence, in order to manage stored grain insect pests a combination of organic and inorganic pesticide control materials was selected to check the efficiency against red flour beetle (Tribolium castaneum) and pulse beetle (Callosobruchus chinensis). Total 10 treatments were used, eight different organic bio-pesticides (neem seed, neem leaves, naswar, tobacco, eucalyptus, citrus, dhatura and mint) and one inorganic (naphthalene balls) and control used at 32 ± 2°C and 70 ± 5% RH. The results indicated that three doses of all treatments were used as 5, 10 and 20gm in 50gm grains. Overall, maximum (4.33 ± 1.00%) mortality of red flour beetle was observed using neem seed powder and no (0.0 0 ± 00%) mortality was observed in minte leaves powder. In case of pulse beetle, the maximum (5.07 ± 0.87%) mortality was observed using neem seed powder and minimum (0.66±0.22%) using citrus leaves powder. Maximum (16.26 ± 0.03) antifeedant efficiency of red flour beetle was observed in control group and minimum (6.46±0.65) antifeedant efficiency of red flour beetle was found in dhatura leaves powder at all tested concentrations. Maximum (14.23 ± 0.13) antifeedant efficiency of pulse beetle was determined in control group and and minimum (1.00 ± 0.04) was observed for naphthalene balls at all tested concentrations. Maximum (94.67%) repellency against red flour beetle was observed using neem seed powder and minimum (62.00%) was found in naphathalene balls as compared with their controls. Maximum (81.32%) repellency against pulse beetle was observed using naswar powder and minimum (63.34%) repellency was determined using neem leaves powder as compared with their control group. We concluded that 20% of neem seed powder concentration proved effective to suppress the population of both red flour beetle and pulse beetle.

Résumé :

The effects of induced translocation stress upon heat pulse velocity, reactions to pathogenic fungi, and bark beetle attack dynamics were compared before, during, and after severe cooling of the bole and after girdling of xylem and phloem in Pinus contorta Douglas var. latifolia Engelmann. Cooled trees evidenced a reduction of heat pulse velocity and the elimination of observable wound responses, which returned to normal upon cessation of the stress the following year. A tree naturally attacked and colonized by Dendroctonus ponderosae Hopkins also evidenced reduced heat pulse velocity within 2 weeks of bark beetle attack. Heat pulse velocity in girdled trees did not change. Stress due to drought and (or) bark beetle attack in nature may be analogous to that induced by cooling. Such stress may reduce a tree's ability to resist bark beetle attack and fungus invasion.

Résumé :

ABSTRACT Plants synthesize many industrially useful chemicals for the benefit of humanity. Plant biopesticides are species specific, less harmful to beneficial arthropods, biodegradable and require low cost in developing formulations than synthetic pesticides that are directly developed from petrochemical derivatives. Twenty different tablet formulations prepared from various combinations of promising plant products have been evaluated for stored pulse grains protection. The natural menthol (9.09%) based tablet formulation containing natural binder and carrier agent-Vigna mungo seed powder (73.63%), liquid preservative-Acetic acid (11.36%), solid powdered preservative - sodium benzoate (5.68%) and edible lemon yellow colour (0.22%) (Treatment - XVII) applied once was found to be the most suitable for the management of adzuki bean beetle, Callosobruchus chinensis L. adult during pulse grains storage period of three and six months. The two tablets/250g grains comprising menthol (XVII) was found to reduce significantly 100% C. chinensis population in jars containing grains of both Cicer arietinum and Lens esculenta up to six months storage period. The beetle population did not increase as compared to average increase range of 245 to 1515 adult beetle populations in C. arietinum and 1825 to 3346 in L. esculenta in other treatments and untreated control during three months of storage. Result indicates that menthol containing cost effective tablets formulation may be developed at commercial level to protect the pulse grains attack of adzuki bean beetles during storage in homes and market places.

Résumé :

Pulse beetle is the major pests of pulses that cause significant loss to grains leads to unfit for consumption and marketing. Indiscriminate use of synthetic pesticides for the control of pulse beetle (Callosobruchus chinensis and Callosobruchus maculatus) led to insect resistance, pesticide residues on grains which affect consumer’s health and environment. Essential oils (EOs) are good alternatives to synthetics due to their safety to the environment and consumers’ health. The main objective of the present study was to explore the chemical composition, fumigant, repellency, ovipositional deterrence, persistence, and detoxification enzyme inhibition of Artemisia maritima essential oil against pulse beetle. Results showed that primary components of the EO were 1,8-Cineole and bornyl acetate. EO showed promising fumigant toxicity to C. chinensis and C. maculatus (LC50 = 1.17 and 0.56 mg/L, respectively) after 48 h. In the repellent assay, EO at 8 mg/L showed 92–96% repellence after 1 h. In ovipositional deterrence assay, EO showed more ovipositional deterrence against C. chinensis (OD50 = 3.30 mg/L) than C. maculatus (OD50 = 4.01 mg/L). Higher concentrations of oil (8 and 6 mg/L) in C. maculatus showed significant inhibition of the glutathione-S-transferase enzyme (7.14 and 5.61 n mol/min/mL, respectively).

Résumé :

An experiment on eco-friendly approach of managing pulse beetle (Callosobruchus chinensis L.) in chickpea (Cicer arietinum L) was carried out at the Institute of Agriculture and Animal Science (IAAS), Rampur, Chitwan, Nepal from April to July, 2007. The experiment consisted of fourteen treatments laid out in two factors Completely Randomized Design (CRD) with three replications. Among them, storage structure (aluminium sheet bin and jute bag with plastic lining) was considered as one factor and pesticidal materials (Xanthoxylum armatum DC fruit dust@ 30gm kg-1; Acorus calamus L. rhizome dust@ 30 gm kg-1; Cinnamom camphora balls@ 1.5 gm kg-1; Sesamum indicum L. oil@ 5 ml kg-1; Azadirachta indica A. Juss. leaf dust@30gm kg-1; malathion dust@ 1gm kg-1 and control) was as another factor. Among six pesticidal materials tested, mortality of adult bruchids was obtained significantly higher in chickpea treated by C. camphora balls (25.17) followed by A. calamus rizome dust (24.83) and Sesamum oil (24.50). Grain damage and weight loss was nil in chickpea treated by these three materials. Among botanicals used, X. armatum fruit dust and A. indica leaf dust were found ineffective to cause adult mortality (20.33 and 19.67) and adult emergence (1549 and 2292) in chickpea. Malathion, initially was found somewhat effective in adult mortality (21.67) and adult emergence (30.33). However, it was less effective from F2 generation resulting maximum adult emergence (2127). While comparing two storage structures, jute bag with plastic lining was better in terms of maintaining lower moisture (14.64%), higher germination (65.14%) and lesser grain damage (39.95%). Thus, the jute bag with plastic lining was found as a better storage structure and botanical materials such as A. calamus rhizome dust, Sesamum oil and C. camphora balls have been found as effective safe alternatives for the management of C. chinensis L. in the storage of chickpea.

Résumé :

Chickpea is the most dominant pulse having a major share under area shown 65 per cent and production 72 per cent followed by lentil and field pea. Pulse beetle, Callosobruchus chinensis L. is a primary pest of stored chickpea which causes 50-60 per cent loss in seed weight and 45.5-66.3 per cent loss in protein content of the seeds (Rustamani et al., 1985) and injudicious and indiscriminate use of hazardous synthetic chemicals for preventing storage losses in chickpea may lead to human and animal health issues due to residual hazards. Therefore, the biorational management of the pulse beetle in stored chickpea has been undertaken keeping biology in mind will prevent the loss as well as protect human health hazard.The experiments on non-chemical biorational approaches like effect of desiccant beadswhich control the pulse beetle efficiently but have lesser toxicity hazards to non-target organisms and the environment was studied in the Department of Entomology, College of Agriculture, OUAT, BBSR, Odisha during 2018-2021.The results showed that desiccant beads viz., zeolite and sodium aluminium silicate impregnated with chickpea seeds in the ratio of 1:1 proved effective in suppression of the pulse beetle in chickpeaduring six months of storage.

Résumé :

Scarabiasis or Canthariasis or Beetle disease is an ectoparasitic infection of the gastrointestinal tract, in which the beetles temporarily infest the digestive tract and rarely the urinary tract. Dung beetle belongs to Scarabiaediae family. It is mostly seen in children aged between 2 to 5 years, who play outdoor for prolonged hours without undergarments. It is a temporary infestation in which early stages of development of beetle takes place in the anus and the adult beetle flies, out of the anus while defecation. A boy aged 3 years and four months presented to the pediatric OPD with complaints of peri umbilical abdominal pain, vomiting, nausea, mucus in stool along with “black insects” in his stool. The clinical examination revealed that the pulse rate, blood pressure and temperature were normal. Per rectal examination and ultrasound of the abdomen was normal. Routine examination of stool and urine was also found to be normal. The beetle was identified by the medical entomologist as dung beetle belonging to family Scarabidae. This report implies that the boy had an infestation with the larvae of dung beetle in the gastro intestine. The family belonged to the high range area of Mundakayam. Agriculture is the main source of income for people and main plantation being Rubber. Natives breed cattle for their livelihood and agriculture. During contact with mud or while playing outdoors naked, he would have come into contact with the eggs or the beetle, which hatched into larvae and caused canthariasis.

Résumé :

Development of pulse beetle (Callosobruchus maculatus Fab.) was studied on nine different pulses viz., mungbean, urdbean, mothbean, greenpea, cowpea, horsegram, chickpea, wal and pigeonpea under laboratory conditions. The study indicated that chickpea was most preferred host by C. maculatus as it recorded highest number of eggs (290.67/100 grains), shortest total developmental period (21.33 days) and highest number of adult emergence (163/100 grains), whereas horsegram was least preferred host as it recorded lowest number of eggs (23.67 / 100 grains), lowest number of adult emergence (4.33/ 100 grains) and shortest adult longevity (4 days). The highest adult longevity was recorded in wal (10 days) followed by chickpea and mungbean (9.33 days). In the case of the incubation period, mungbean and cowpea recorded shortest incubation period (2.67 days) and followed by chickpea, green pea and pigeonpea (3.33 days) whereas it was highest in urdbean (4.67 days) followed by horsegram (4.33 days). Percent adult emergence was lowest in the case of horsegram (18.29%) followed by mothbean (19.86%) and was highest in wal (74.92%).

Résumé :

Pulses serve as one of the main sources of protein and minerals as well as play a vital socio-economic role in the diet of common people of Bangladesh but these pulses suffer enormous losses due to infestation of a serious insect pest pulse beetle, Callosobruchus chinensis L. As a part of eco-friendly management of this detrimental pest, an experiment was conducted at the laboratory to determine the toxicity of spinosad against the pulse beetle, C. chinensis L. directly by using dry film contact toxicity method and indirectly by treating chickpea seeds. In the direct method spinosad showed contact toxicity and the lethal concentration of spinosad was 117.46, 76.05 and 37.45 ppm at 24, 48 and 72 hours after treatment, respectively. On the other hand, the LC50 values were 990.34, 301.35 and 95.08 ppm after 24, 48 and 72 HAT, respectively as per indirect method. A dose-dependent relation with the mortality was observed by both methods. Spinosad was also significantly effective in reducing the number of eggs (68.00 to 98.60% inhibition over control), adult emergence (56.70 to 100% inhibition over control), percent seed infestation (62.79 to 100% inhibition over control) and seed weight loss (50.81 to 100% inhibition over control). The present results indicated that spinosad could be suggested for the efficient management of C. chinensis in storage. J. Bangladesh Agril. Univ. 16(3): 411–416, December 2018

Résumé :

Pulse beetle, Callosobruchus chinensis L. (Coleoptera: Chrysomelidae) is the most economic insect pest of pulse and can cause huge quantitative losses and also decreases the nutritional value of stored products. The morphological and molecular characterization of pulse beetles was determined and different non-edible oils against C. chinensis were assessed at ICAR-National Bureau of Plant Genetic Resources, New Delhi during 2019â€“20. Eggs of C. chinensis were 264.74Â±3.716 Î¼m in width and 452.33Â±4.531 Î¼m in length. The final instar larva of C. chinensis was 1703.12Â±4.692 Î¼m in width and 3062.19Â±33.119 Î¼m in length. The width and length of the pupae was 1696.09Â±5.589 Î¼m and 3281.60Â±73.641 Î¼m, respectively. The length of the adult body was 2520.85Â±23.278 Î¼m for females and 2469.70Â±29.570 Î¼m for males with a width of 1426.78Â±41.334 Î¼m for females and 1456.54Â±23.606 Î¼m for males. Both C. maculatus and C. chinensis got amplified by COI primer. A band of approximately 710 bp was obtained from both pulse beetles (C. maculatus and C. chinensis). DNA barcode helps in identification of pests at all life stages. Hundred per cent of egg mortality, larval mortality and adult mortality were reported in all non-edible oils such as Pongamia glabra L., Hydnocarpus wightiana Blume, Madhuca longifolia Konig, Callophyllum inophyllum L. and Azadirachta indica A. Juss. Similarly, all non-edible oils had ovipositional deterrence. To summarize, these oils can be used for the management of pulse beetles during storage.

Résumé :

Historic regeneration patterns and regeneration requirements were investigated in an old, self-regenerating lodgepole pine (Pinusconforta Dougl. ssp. murrayana (Balf.) Critchfield) forest in south central Oregon. The forest was multiaged, with episodic regeneration pulses being correlated with mountain pine beetle (Dendroctonusponderosae Hopk.) outbreaks or fire. The magnitude of a regeneration pulse was a function of disturbance intensity. Tree ring indices show growth declines prior to mountain pine beetle outbreaks. Radial tree growth improved following disturbance. Differences in stand structure among climax lodgepole pine stands in the Rocky Mountains, Sierra Nevada, and south central Oregon were related to disturbance type, frequency, and intensity. Successful lodgepole pine reproduction was limited by soil moisture and partly by microclimate. Shading did not inhibit seedling establishment, but rather provided relief from excessive evapotranspiration, heat, and frost.

ABSTRACT Laboratory bioassay was carried with five different concentrations of Beauveria bassiana (1x104 to 1x 108 ml-1) against the pulse beetle, Callosobruchus maculatus. Stored seeds were severely attacked by the pulse beetle, Callosobruchus maculatus, a coleopteran pest.At the larval stage, it penetrated into stored seeds and fed on cotyledons. Entomopathogenic fungus, Beauveria bassiana caused maximum oviposition reduction and 100% adult mortality was obtained at higher concentrations. Mortality declined with the decrease in concentrations. At higher concentrations, oviposition reduction was 60.58%, and adult mortality was 99.44% at 92h respectively. It showed higher virulence compared to other isolates.At lower concentrations, oviposition reduction was 23.82% and adult mortality was 81.93% at 92 h respectively.

Résumé :

Results of the evaluation on bioefficacy of three indigenous plant extracts for toxicity and residual effects against the pulse beetle, Callosobruchus chinensis L. (Bruchidae: Coleoptera) showed that the plant extracts had toxic and residual effects for controlling pulse beetle. Mortality and residual effects were statistically different among the plant extracts and doses applied. Neem extract showed the highest adult mortality (36.78%) whereas eucalyptus extract showed the lowest (22.75%). The order of the toxicity of three plant extracts was found as neem > custard apple > eucalyptus. Mortality was found directly proportional to the hour after treatments which increased with the progress of time. Between two solvents, acetone solvent possessed the highest toxicity (mortality 32.95%) but methanol showed the lowest toxicity (mortality 30.56%). The residual toxicity was evaluated on the basis of egg laid, adult emergence, seed infestation and weight loss caused by the insect. The highest residual toxicity was found in neem extract with acetone while the lowest in eucalyptus extract with acetone. Neem extract with acetone and custard apple extract with methanol solvent were found effective to toxic and residual effects against pulse beetle of three plant extracts applied. Asiat. Soc.

Résumé :

Pulse beetle is the most harmful pest attacking stored grains and affecting quality and marketability. Continuous use of chemical-based pesticides against pulse beetle led to the development of insecticidal resistance; essential oils (EOs) can be an effective natural alternative against this pest. The main objective was to study the chemical composition of seven EOs viz., Acorus calamus, Hedychium spicatum, Lavandula angustifolia, Juniperus recurva, Juniperus communis, Cedrus deodara and Pinus wallichiana, their insecticidal and enzyme inhibition activities against pulse beetle. The primary compounds present in these EOs were cis-asarone, 1,8-cineole, linalyl isobutyrate, 2-β-pinene, camphene, α-dehydro-ar-himachalene and camphene. A. calamus oil showed promising fumigant toxicity to Callosobruchus maculatus and C. chinensis (LC50 = 1357.86 and 1379.54 µL/L, respectively). A combination of A. calamus + L. angustifolia was effective against C. maculatus and C. chinensis (LC50 = 108.58 and 92.18 µL/L, respectively). All the combinations of EOs showed synergistic activity. In the repellency study, A. calamus showed more repellence to C. maculatus and C. chinensis (RC50 = 53.98 and 118.91 µL/L, respectively). A. calamus and L. angustifolia oil at 2500, 5000 and 10,000 µL/L significantly inhibited the AChE and GST enzymes in C. maculatus and C. chinensis after 24 and 48 h.

Résumé :

Context: Dinarmus basalis (Rond.) is a larval-pupal ectoparasitoid of the pulse beetles, Callosobruchus (Coleoptera: Bruchidae). This parasitoid could be used in suppressing the pulse beetle populations in stored conditions. Objective: To observe the influence of different food supplements on the progeny production and sex ratio of D. basalis when exposed to the pulse beetles separately. Materials and Methods: Mated females of D. basalis were introduced into separate Petri dishes (9.5 cm diam) containing 50 mature mung seeds infested with C. chinensis and C. maculatus. The parasitoids were provided with host and honey, host and sugarcane, host and egg yolk, host and yeast and host and agar, and host without food individually. After 24 h, the parasitized larvae with seeds were changed and the female parasitoids were provided with foods daily until adults died. After emergence total number of hosts and parasitoids were counted. The sex ratio of D. basalis were also calculated and their chi-squared tests were made. Results: The mean number of progeny production of D. basalis on C. maculatus-infested blackgram was significantly greater than those reared on C. chinensis-infested mug in all food regimes (Table 1). The progeny production on two host beetles differed significantly in relation to different foods (F= 4.85, P<0.01. C. chinensis; F= 38.34, P<0.01, C. maculatus). The most effective food supplement was honey, which enhanced offspring production of D. basalis on both the hosts, and egg yolk was the least effective. The percentage of progeny was more or less female-biased in all the treatments except the control. Conclusion: Food supplementation of D. basalis will significantly increase the efficiency of the parasitoid against storage pests including the pulse beetles.

Résumé :

ABSTRACT The pulse beetle Callosobruchus chinensis Linn. (Coleoptera:Bruchidae) is one of the major pests of pulses in storage. During the present study an attempt was made to screen and compare the efficacy of Ocimum sanctum and Ocimum basilicum (Lamiaceae) on egg-laying performance of the bruchid on grains of Vigna radiata (mung). The leaves of the select two plants were employed in the form of crude extract, powder suspension, aqueous extract, ethanol extract and diethyl ether extract at dose concentrations of 10, 25 and 50%. Significant reduction (P< 0.05) in oviposition was documented in sets treated with the formulations of both the plants as compared to control and normal. The formulations of O. basilicum were observed to be superior to O. sanctum in reducing egg-laying. Moreover, ethanol extract, crude extract and powder suspension were also noted to significantly bring down the number of eggs laid by the pulse beetle. Dose concentration was found to be inversely proportional to the number of eggs laid by the bruchid and formulations of 50% concentration resulted in minimum oviposition. The results suggest that formulations of both the species of Ocimum have a potential to act as ovipositional deterrent and can beemployed against C.chinensis for its control.

A biologically active extract from the darkling beetle Ulomoides dermestoides was obtained using the electro-pulse plasma dynamic extraction method. The beetle water extract contained a complex of antioxidant substances such as antioxidant enzymes and nonprotein antioxidants, as well as a complex of heat shock antistress proteins. This determines the rather high antioxidant activity of the aqueous extract of the beetle, i.e., 1 mg of dry matter/mL of the extract has an equivalent antioxidant activity to 0.2 mM Trolox (a water-soluble analog of vitamin E). It was shown that the beetle extract can lead to a 25–30% increase in the average lifespan of nematode Caenorhabditiselegans, under normal conditions, and a 12–17% increase under conditions of oxidative stress (with paraquat), and significantly inhibits the fructosylation reaction of serum albumin. Therefore, the beetle aqueous extract shows promise as a biologically active complex exhibiting antioxidant activity.

Résumé :

Mungbean is one of the important pulse crops in Bangladesh. More than 12 species of insect pests infest mungbean, among them flea beetle cause significant yield loss due to attack from seedling to vegetative stages. The experiment was conducted to find out tolerant and susceptible varieties of mungbean against flea beetle at the farmer’s field of Patuakhali, Bangladesh from January to April 2016. Results revealed that BARI Mung-4 had the lowest abundance of flea beetle while BINA Moog-7 and BARI Mung-6 had the highest flea beetle abundance. Among the tested all varieties, significantly the lowest number (1.33) of infested plant by flea beetle was recorded in BARI Mung-4 followed by BINA Moog-4 (1.51) and the highest number (2.54) of infested plant by flea beetle was in BARI Mung-6 followed by (2.42) BINA Moog-7. The lowest percentage of leaf area damaged was on BARI Mung-4 (5.37%) while the highest on BARI Mung-6 (11.33%). Population of flea beetle showed a positive correlation (R2= 0.019) with temperature and a negative correlation (R2= -0.01) with relative humidity. BARI Mung-6 produced highest yield while Patuakhali local Mung produced the lowest followed by BARI Mung-4. Among tested varieties BARI Mung-4 showed comparatively more tolerant against flea beetle and BARI Mung-6 produced maximum yield in spite of being susceptile to flea beetle.

Résumé :

Whitebark pine (Pinus albicaulis Engelm.) is vulnerable to mountain pine beetle (Dendroctonus ponderosae Hopkins) attack throughout western North America, but beetle outbreaks in the southwestern portion of the range (i.e., Sierra Nevada) have been spatially limited until recently. We examined patterns of mortality, structure, and regeneration in whitebark pine stands impacted by mountain pine beetle in the southern Sierra Nevada. Mortality was greatest in medium to large diameter (>10–20 cm dbh) trees, resulting in declines in mean and maximum tree diameter and tree size class diversity following an outbreak. Severity of beetle attack was positively related to mean tree diameter and density. Density of young (<3 years old) whitebark pine seedling clusters was positively related to severity of beetle attack on mature stands. All sites showed a stable production of whitebark pine regeneration within at least the past 30–40 years, with a pulse of new seedlings in the past 3 years in beetle-impacted stands. Our results show that mountain pine beetle outbreaks in the southern Sierra Nevada result in substantial changes in whitebark pine stand structure and suggest low resistance but high resilience to initial attack, especially in the absence of white pine blister rust.

Population development and grain damage by C. chinensis was assessed on eight different host-grains viz., greengram (Vigna radiata L.), blackgram (Vigna mungo L.), Bengalgram (Cicer arietinum L.), redgram (Cajanus cajan L.), cowpea (Vigna sinensis L.), soybean (Glycine max L.), pea (Pisum sativum L.) and pillipesara (Phaseolus trilobus L.) were estimated. Among all the host-grains, maximum oviposition was recorded in blackgram (7.75 eggs/ 5 g grain). Survival was highest in bengalgram (86.43) and mean developmental period was shortest in greengram (28.47 days) which were on par with that in pillipesara (28.77 days) whereas index of susceptibility was highest in greengram (6.09) and was followed by pillipesara (6.03). The damage in terms of percentage of grains damaged and weight loss of grains increased with increase in storage period. Among all the host-grains bengalgram recorded significantly maximum percentage of grain damage (90.65%) and weight loss of grains (58.55%).

The seeds of French bean were subjected to different seed treatments viz., T0: Control (untreated), T1: Neem leaf powder @5g/kg of seed, T2: neem oil @5ml/kg of seed, T3: Castor oil @5ml/kg of seed, T4: karanj oil @5ml/kg of seed, T5: vekhand powder @10g/kg of seed, T6: Termuric powder @5g/kg of seed, T7: Citronella oil @5ml/kg of seed, T8: Ash @5g/kg of seeds, T9: Deltamethrin @0.04ml/kg of seed. Seed health was tested for different parameters viz., pulse beetle infestation, seed weight loss, egg-laying, adult emergence, percent mortality, dead insects and live insects. The bio-efficacy test was undertaken to find out the effect of chemicals and different botanicals against pulse beetle in French bean seed. Results revealed that seeds treated with Deltamethrin @0.04ml/kg of seed significantly recorded the lowest pulse beetle infestation (1.33%), lower number of egg-laying (11.00), lowest number of adult emergence (1.67), lowest seed weight loss (4.67%), highest mortality (87.8%), higher dead insect (15.00) and lower live insect (5.00) at the end of storage period. Among the botanicals, seed treated with neem oil @5 ml/kg of seed showed higher seed quality and health parameters. From the present investigation, the seed treated with organic and inorganic components protected the seed health while, the control seed deteriorated at the end of the storage period.

Chickpea grain samples (500g each) were collected during August, September and October from different storage structures (metal bins, plastic bags, gunny bags, earthen pots and earthen pots + sand) in 15 villages of Rewari, Hisar and Mahendergarh district in the year 2017 and 2018. The results of analysed samples revealed that the highest infestation was observed in Rewari followed by Hisar and Mahendergarh district. It was found that maximum number of farmers were using metal bins (51.45, 40.11%) followed by gunny bugs (31.79, 31.64%), plastic bags (16.76, 15.82%), Earthen pots (6.51, 7.91%) and Earthen pots + sand (2.35, 4.52%) to store the chickpea grains in 2017 and 2018, respectively. Out of total samples infested with bruchid, 70.91 & 53.63 per cent gunny bag samples were found infested followed by plastic bags (48.28 & 20.29%), metal bins (11.24 & 15.94%) and earthen pots (9.80 & 10.14%) in both the years. There was no infestation of pulse beetle observed in those samples which were stored in earthen pots along with sand. Higher moisture percentage in the grain and infestation of pulse beetle was observed in the month of September followed by October in comparison to August month. Among the storage structures in frequent use, metal bins were found to have less qualitative and quantitative losses of seed/grains.

Résumé :

When 10 plant oils were tested at 0.02, 0.05 and 0.1 per cent against the pulse beetle for their bio-activity, it was observed that neem oil at all the three doses reduced egg hatching, adult emergence and seed weight loss. All oils were effective at 0.1 per cent concentration. At 0.5 and 1.0 per cent, the development of the beetle was greatly affected as evident from no adult emergence and complete protection of seed was achieved. Further, the oil treatments affect the germination of the greengram seeds.

Résumé :

Two hundred bengal gram accessions (Cicer arietinum L.) were screened for their resistance to Callosobruchus maculatus (F) by Free Choice Test. The number of eggs laid varied from 4 to 60. The adult emergence ranged between one in 11 and 27 in 5 accessions. Hundred per cent survival was observed in four accessions (Shahkot- 2, P-1675, RFG 30 and NEC-1592) as against only five per cent survival in RBH 99 and RC 109. Ovipositional preference was found not related with the suitability of the accession for further development. C. maculatus took 25 to 41 days for development. Based on the suitability index, 22 accessions were categorised as resistant, 40 as moderately resistant, 109 as susceptible and 29 as highly susceptible to C. maculatus.

Résumé :

The pesticidal efficacy of four locally available leaves of botanicals like neem (Azadirachta indica), datura (Datura stramonium), marigold (Tagetes erecta) and garlic (Allium sativum L.) tablet powders was assessed on pulse bettle (Callosobruchus chinensis L) through adult mortality and emergence, oviposition performance, seed damage, weight loss and germination of chickpea (Cicer arietinum). The above test biopesticides were tested at three different rates (0.5 g, 1.0 g and 1.50 g powder/kg of chickpea seeds). All the tested powder showed significant effect on the above parameters. The highest adult mortality was recorded when chickpea seeds were treated with datura leaf powder at 1.50 g/kg, whereas marigold showed the least effect on adult mortality. The powders used in the experiment effectively controlled oviposition and adult emergence of pulse beetle. The lowest number of adult emergence was obtained from chickpea seeds treated with datura leaf powder at 1.50 g/kg. The highest weight loss was observed in control seeds followed by marigold leaf powder 0.5 g/kg gram seeds. Datura leaf powder treated seeds showed the lowest seed weight loss followed by neem, garlic and marigold. Plant powders had profound effect on seed germination. The highest germination was observed in treated seed with datura leaf powder at 1.50 g/kg and the lowest germination in control seed followed by marigold leaf powder at 1.5 g/kg treated seeds. The pesticidal effect on oviposition, adult mortality, adult emergence, and seed weight loss was directly proportional to leaf powder rates.
