Abstract:

Tobacco leaf discs were transformed with a plasmid, pBIAHA, containing the selectable marker neomycin phosphotransferase gene (nptII) and an Arisaema heterophyllum agglutinin gene (aha) via Agrobacterium tumefaciens-mediated transformation. Thirty-two independent transgenic tobacco plants were regenerated. PCR and Southern blot analyses confirmed that multiple copies of the aha gene had integrated into the plant genome. Northern blot analysis revealed that the aha gene was expressed at various levels in the transgenic plants. Insect bioassay test showed that transgenic plants expressing multiple copies of the aha gene reduced the rate of population increase of the peach potato aphid (Myzus persicae Sulzer). This is the first report that transgenic tobacco plants expressing the aha gene display enhanced resistance to aphids. Key words: Insect bioassay, Arisaema heterophyllum agglutinin, transformation, transgenic tobacco, peach potato aphid (Myzus persicae Sulzer)

Abstract:

Multivariate morphometric analysis was used to compare nine characteristics of 47 populations of Myzus persicae (Sulzer) originating from two host-plants, peach and tobacco, from 13 localities in 2004 and 34 localities in 2005, in Serbia and Montenegro. Multivariant discriminant analysis showed there to be a distinct discrimination between the populations from the peach and tobacco host-plants. The most important discrimination characteristics are the ultimate rostral segment length and processes terminalis length, which are greater in the aphids from tobacco than in those from peach. This is the first indication that in this part of Europe there are two subspecies: M. persicae (Sulzer) and M. persicae nicotianae Blackman. .

Abstract:

AbstractA dark green aphid was isolated from a greenhouse colony of green peach aphid, Myzus persicae (Sulzer), in Fredericton, N.B. The green aphid was shown to conform taxonomically and biologically to the recently named species Myzus nicotianae Blackman, except for its rare production of alatae. It is reported for the first time on greenhouse-grown potato where its population development is similar to that of the yellow holocyclic M. persicae from the same colony. The vector efficiency of the green and yellow aphids for potato virus Y0 is similar. The yellow aphid tends to be more susceptible to insecticides than the green aphid. Myzus nicotianae was not found in aerial aphid samples taken in New Brunswick in 1967 and 1987.

Se investigó el rol de los hospederos primarios de M. persicae, principal vector de PVY, en la epidemiología de este virus en Malargüe, Mendoza, Argentina, en un área protegida para la producción de tubérculos semilla de papa. En el ciclo 1989- 1990, se realizó un relevamiento de este áfido sobre posibles hospederos primarios y secundarios. Se estudió el ciclo biológico de M. percicae en el área de estudio. Se efectuó un análisis morfométrico de individuos alados de esta especie, capturados en trampas amarillas de agua, lo que permitió determinar la proporción de formas holocíclicas y anholocíclicas presentes. Solamente Prunus percica y P. pissardii resultaron colonizados por M. persicae, constatándose además, que esta especie puede invernar también en forma partenogenética sobre hospederos secundarios. El análisis morfométrico indicó que las formas holocíclicas pueden representar entre el 50 y 100% de los individuos alados que visitan cultivos de papa al comienzo del ciclo, cuando las plantas son más sensibles al PVY. Esto indica que la relevancia de hospederos primarios especialmente durazneros (P. persica), en a la dispersión temprana del virus.Aceptado para publicación: abril 2, 1994

Abstract:

AbstractMultivariate techniques, principally the method of canonical variates, were used to investigate morphological variation within and between populations of the group of Myzus persicae (Sulzer) from North and South America, Europe, Africa and Asia. The scores on the first canonical variate of samples from tobacco in North America, the Mediterranean region, the Middle East, Africa and Sri Lanka all grouped consistently when compared with samples from other host-plants, even after aphids from tobacco had been reared for up to seven years on a non-tobacco host. Thus there is a widely-distributed tobacco-adapted form, closely related to M. persicae but with its own characteristic morphology. Morphological discriminants are given for the recognition of apterous and alate viviparae of this tobacco form, which is given the name M. nicotianae sp. n. Both M. persicae and M. nicotianae have 2n = 12, and both are frequently heterozygous for apparently the same autosomal translocation, which they must have acquired independently. M. nicotianae is presumably isolated from M. persicae by being permanently parthenogenetic. In Japan and Central Asia, however, aphids of the M. persicae group on tobacco can produce sexual morphs; the taxonomic status of these latter populations is still unclear. Multivariate comparison of European and North American populations of dark green aphids of the M. persicae group with 13 or 14 chromosomes in somatic cell nuclei instead of the normal 12, led to the conclusion that these all belong to one morphologically variable taxon, M. antirrhinii (Macchiati). Keys are provided to the apterous and alate virginoparae of the species of the M. persicae group in America.

Abstract:

In two years of investigating resistance of the peach-potato aphid Myzus persicae (Sulzer) by molecular methods, several types of resistance were established in the majority of individuals from peach and tobacco in Serbia and Montenegro. Most of the tested individuals had the FE4 gene, which encodes production of FE4 esterase. The gene responsible for kdr (knock-down resistance) was found in the majority of individuals, but in the heterozygous state, while resistance based on formation of modified acetlycholinesterase (MACE) was least represented. Also, tests showed aphids from tobacco to be more sensitive to insecticide action than aphids from peach. Three tests were used in these investiga?tions, e.g., the PCR - esterase, PCR - kdr, and RFLP - PCR tests, each for a single type of resistance.

Abstract:

The green peach aphid, Myzus persicae, is globally distributed and an important pest of many economically valuable food crops, largely due to its ability to transmit plant viruses. Almost all aphids, including M. persicae, carry the obligate symbiont Buchnera aphidicola, which provides essential amino acids that aphids cannot obtain from the phloem of plants themselves. Many aphids also harbor facultative (secondary) endosymbionts, which provide benefits under specific ecological conditions. In this study, we screened for secondary endosymbionts in M. persicae, with a particular focus on Australian populations where this species is growing in status as a major agricultural pest. We compared 37 Australian M. persicae populations with other populations, including 21 field populations from China and 15 clones from the UK, France, Italy, Greece, USA, Spain, South Korea, Chile, Japan and Zimbabwe. No secondary endosymbionts were identified in M. persicae samples outside of China, despite samples covering a wide geographic range and being collected from several host plant families. We detected two secondary endosymbionts (Rickettsia, Spiroplasma) in Chinese samples, although diversity appeared lower than detected in a recent study. We also found very high clonal diversity in Chinese samples based on DNA microsatellite markers in comparison with lower clonal diversity from Australia. These patterns may indicate a higher diversity of secondary endosymbionts (and clonal diversity) in the native range of M. persicae when compared to its invasive range.

Este trabalho teve como objetivo avaliar o efeito de diferentes temperaturas no desenvolvimento ninfal de Myzus persicae sobre folhas de berinjela (Solanum melongena). O experimento foi desenvolvido em câmaras climatizadas, sob condições controladas de temperatura de 15, 20, 25 e 30 ± 1 ºC, umidade relativa do ar de 70% ± 10% e fotofase de 12 horas. A biologia de M. persicae foi acompanhada sobre discos foliares de berinjela (3 cm de diâmetro) mantidos em placas de Petri contendo solução ágar-água a 1% geleificada. Foram estimadas as curvas mais ajustadas à duração dos estádios ninfais de M. persicae, suas equações de regressão e os respectivos coeficientes de determinação (R²). O número de estádios ninfais foi afetado pela temperatura; a 15 e 20 ºC, respectivamente, em 30,4% e 4,2% das ninfas observou-se um estádio adicional. Afídeos mantidos a 30 ºC apresentaram a menor viabilidade na fase ninfal (8%). A duração da fase ninfal foi de 9,4; 7,6; 5,9 e 7,0 dias, respectivamente, a 15, 20, 25 e 30 ºC. As temperaturas de 15 e 20 ºC foram as mais favoráveis para o desenvolvimento ninfal de M. persicae sobre discos de folha de berinjela.

Abstract:

Abstract Lecanicillium lecanii is a potential effective entomopathogen against various insect pests. Some isolates of Lecanicillium is also reported as endophytic. However, the information on endophytic colonization of L. lecanii PTN 10 and its role in conferring tobacco resistance against Myzus persicae is not available. The objective of the research was to determine the endophytic colonization ability of L. lecanii on tobacco plants and its effect on the biology and population growth of Myzus persicae. This research consisted of four treatments i.e. untreated plants (K), seed treated with conidia suspension of L. lecanii for 12 hours (P1), foliar spray using conidia suspension L. lecanii one week after transplanting (P2), and the combination of seed treatments and foliar spray. All treated tobacco plants were infested by first nymph of M. persicae one week after L. lecanii treatment. The observations include aspects of biology i.e. life cycle, fecundity, and the longevity of M. persicae. L. lecanii is proven able to colonize tobacco leaves endophytically. The fungus treatment on tobacco plants causes a prolonged life cycle, decreases fecundity, and significantly shortens longevity. Additionally, it suppresses population growth of M persicae.

Abstract:

AbstractThe well-established carboxylesterase-based resistance to insecticides in Myzus persicae Sulzer has recently been accentuated by the appearance of aphids with a modified acetylcholinesterase (MACE) insensitive to pirimicarb and the novel aphicide, triazamate. This target site resistance mechanism was found in M. persicae from crops in the UK for the first time in 1996, together with especially large proportions of aphids with R2 and R3 levels of carboxylesterases, a combination that was associated with serious insecticide failures. This paper describes the incidence of both mechanisms and discusses the implications for future recommendations for aphid control in the UK.

Abstract:

Aphids are among the most harmful crop pests, damaging plants by sucking sap or by transmitting pathogenic viruses. Plant infestation by aphids depends on their population growth. Entomopathogenic fungi are essential participants of terrestrial and aquatic ecosystems, regulating arthropod communities. Many fungal species with a symbiotic–endophytic relation with plants are pathogenic, producing insecticides or insect repellents. The present study investigated the effects of the fungal entomopathogens Beauveria bassiana, Metarhizium anisopliae and Isaria fumosorosea, following their endophytic colonization of the sweet pepper Capsicum annum, on the development of the green peach aphid Myzus persicae. After 21 days, B. bassiana produced 100% aphid mortality, M. anisopliae 90% and I. fumosorosea 83.3%. There were also significant differences in terms of the effect on aphid population in planta and on the survival time of young adults in planta. External mycelium appeared within 96 h after placing aphid cadavers on damp filter paper. PCR confirmed that the mycelium was of B. bassiana, M. anisopliae and I. fumosorosea. DNA sequences collected from this work were matched with existing sequences data in GenBank, using the Basic Local Alignment Search Tool. Our results showed that none of the three fungal isolates had an effect in promoting or suppressing the growth of C. annum.

Abstract:

In a previous report (Jansson and Smilowitz 1985), several life statistics of Myzus persicae (Sulzer) were compared on upper and lower leaves of three potato cultivars (Solanum tuberosum tuberosum cvs. Katahdin, Norchip, and Superior). In general, life statistics were similar (p > 0.05) between cultivars. However, certain life statistics (fecundity and intrinsic rate of increase) consistently were greater (p < 0.05) on lower leaves than on upper leaves of each cultivar. In the previous study, we did not include data on age-specific survival or the relationship between fecundity and longevity to support the premise that the population dynamics of M. persicae on potato are related to the physiological age of leaves (i.e. nutritional quality of leaves) (see Jansson and Smilowitz 1985). This information would be useful for developing a model describing the population dynamics of M. persicae. For this reason, we present here data on age-specific survival and the relationship between fecundity and longevity of M. persicae on upper and lower leaves of three Dotato cultivars.

Abstract:

The green peach aphid (Myzus persicae Sulzer), a major and harmful chili aphid usually managed using chemical pesticides, is responsible for massive annual agricultural losses. The efficacy of two protein elicitors, PeaT1 and PeBC1, to stimulate a defensive response against M. persicae in chili was studied in this study. When compared to positive (water) and negative (buffer, 50 mM Tris-HCl, pH 8.0) controls, the rates of population growth (intrinsic rate of increase) of M. persicae (second and third generations) were lower with PeaT1- and PeBC1-treated chilli seedlings. M. persicae demonstrated a preference for colonizing control (12.18 ± 0.06) plants over PeaT1- (7.60 ± 0.11) and PeBC1 (6.82 ± 0.09) treated chilli seedlings in a host selection assay. Moreover, PeaT1- and PeBC1-treated chilli seedlings, the nymphal development period of the M. persicae was extended. Similarly, fecundity was lowered in the PeaT1- and PeBC1-treated chilli seedlings, with fewer offspring produced compared to the positive (water) and negative controls (50 mM Tris-HCl, pH 8.0). The trichomes and wax production on the PeaT1 and PeBC1-treated chilli leaves created a disadvantageous surface environment for M. persicae. Compared to control (30.17 ± 0.16 mm−2), PeaT1 (56.23 ± 0.42 mm−2) and PeBC1 (52.14 ± 0.34 mm−2) had more trichomes. The levels of jasmonic acid (JA), salicylic acid (SA), and ethylene (ET) were significantly higher in the PeaT1- and PeBC1-treated chili seedlings, indicating considerable accumulation. PeaT1 and PeBC1 significantly affected the height of the chili plant and the surface structure of the leaves, reducing M. persicae reproduction and preventing colonization, according to the data. The activation of pathways was also part of the defensive response (JA, SA, and ET). This present research findings established an evidence of biocontrol for the utilization of PeaT1 and PeBC1 in the defence of chili plants against M. persicae.

Abstract:

AbstractEsterase-based resistance in the peach-potato aphid, Myzus persicae (Sulzer), is generally due to one of two alternative amplified carboxylesterase genes, E4 or FE4 (fast E4). The E4 amplified form is distributed worldwide and it is correlated with a particular translocation between autosomes 1 and 3, whereas the FE4 form, which has hitherto not been found to be associated with chromosomal rearrangements, is typical of the Mediterranean regions. In this study, we present for the first time cytogenetic and molecular data on some M. persicae parthenogenetic lineages, which clearly show a chromosomal A1-3 translocation associated with esterase FE4 genes and unrelated to high levels of esterase-based resistance.

Abstract:

AbstractThe emergence of resistance mechanisms to, and revocation of, many insecticides used in the control of the polyphagus aphid pest, Myzus persicae (Sulzer), has increased the pressure to develop novel approaches for the control of the pest in many crops. Kaolin-based particle films provide a physical barrier against insect pests and show considerable potential for controlling M. persicae. We conducted a series of laboratory experiments to investigate the mode of action of kaolin against aphids. The material appeared to have no direct effect on M. persicae; spraying adult aphids with aqueous kaolin suspension had no significant impact on their subsequent survival or reproduction on untreated plants. Similarly, when aphids were placed on kaolin-treated host-plants (Brassica oleracea), their performance (survival, growth rate and reproduction) was not significantly different from aphids on untreated plants. However, when M. persicae were given a choice between kaolin-treated and untreated (or water solvent-treated) leaf areas, both adults and nymphs exhibited a significant preference for non-kaolin-treated host-plant material. Rejection of kaolin-treated plant material occurred very rapidly (within 20 min) and this behavioural effect may be related to the efficacy of kaolin in controlling aphids under field conditions.

Abstract:

The peach potato aphid, Myzus persicae (Sulzer), is a worldwide pest of many crops, and the most important aphid pest of peach and potato crops in Tunisia, mainly due to virus transmission, for which insecticides are frequently applied. We studied the genetic structure of M. persicae populations in Tunisia, in order to further our understanding of the biotic and abiotic factors shaping populations and to predict their evolutionary responses to the present management practices. We monitored peach orchards and seed potato crops in different seasons and regions from 2011–2013 and in 2016 (19 populations), assessing the genetic diversity of M. persicae at six microsatellite loci. Temporal and spatial changes in the frequency and distribution of 397 genotypes in 548 sampled aphids were studied. Only 37 genotypes were found more than once (clonal amplification), as most genotypes were found only once (91.60% in peach; 88.73% in potato crops). A similarly high genetic diversity was observed in aphids sampled from peach (G/N = 0.76; Ho = 0.617) and potato (G/N = 0.70; Ho = 0.641). Only a weak genetic differentiation among populations was found, mainly between geographic locations. Clustering analysis revealed genotypes to be grouped mainly according to host plant. The availability of the primary host, high proportion of unique genotypes, high genetic diversity and lack of structuring suggest that the aphid reproduces mainly through cyclical parthenogenesis in Tunisia. On the other hand, we provide a farm-scale study that shows how easily M. persicae can colonize different areas and hosts, which may have important implications in relation to plant virus vectoring.

Abstract:

AbstractThe electrophoretic mobility of the enzyme glutamate oxaloacetate transaminase (GOT) on cellulose acetate plates was compared among sibling species of the Myzus persicae (Sulzer) group (M. persicae, M. nicotianae Blackman, M. antirrhinii (Macchiati)). M. persicae itself is monomorphic for GOT-1 (genotype ff), whereas European populations of M. nicotianae are polymorphic for this enzyme, with two forms of slightly different mobility (alleles s, f). In the samples of M. nicotianae examined, M. persicae-likeff genotypes were rare and heterozygotes (sf) were in large excess, even in samples from Greece where M. nicotianae has a regular holocycle (i.e., annual sexual reproduction). In North America, where M. nicotianae is probably entirely anholocyclic, samples of both red and green colour morphs of this species were found to be heterozygous for GOT-1. The enzyme difference can thus provide a means of distinguishing most individual specimens, including trapped alatae, of M. persicae and M. nicotianae. The anholocyclic taxon M. antirrhinii appears to be a fixed heterozygote for GOT-1 and thus resembles most M. nicotianae, but can be distinguished electrophoretically from both M. persicae and M. nicotianae by its distinctive pattern of esterases.

Abstract:

O afídeo Myzus persicae (Sulzer, 1776) (Hemiptera: Aphididae) é uma das principais pragas de diversas culturas em condições de campo ou em cultivo protegido. Este trabalho teve por objetivo avaliar o efeito de diferentes temperaturas na longevidade e nos aspectos reprodutivos de M. persicae sobre berinjela (Solanum melongena L.). O experimento foi conduzido sob condições controladas de temperatura (15, 20, 25 e 30°C), umidade relativa do ar (70 ± 10%) e fotofase (12 horas). As unidades experimentais consistiram de placas de Petri contendo ágar-água solidificado (1%). Nestas placas, os afídeos foram mantidos individualmente sobre os discos foliares de berinjela (3 cm de diâmetro) em uma das temperaturas (tratamentos), com 25 repetições. Foram determinadas as curvas mais ajustadas aos parâmetros biológicos de M. persicae, suas equações de regressão e os respectivos coeficientes de determinação (R²). A temperatura influenciou todos os parâmetros avaliados. As durações dos períodos pré-reprodutivo e reprodutivo de M. persicae variaram de 0,46 dia (25°C) a 1,12 dia (15°C) e de 3,89 dias (25°C) a 19,11 dias (15°C), respectivamente. A fecundidade total e diária foi de 17,63 ninfas/fêmea e 4,38 ninfas/fêmea/dia a 25°C; 43,63 ninfas/fêmea e 4,34 ninfas/fêmea/dia a 20°C; 60,65 ninfas/fêmea e 3,15 ninfas/fêmea/dia a 15°C. A 30°C, não houve reprodução. A duração do período pós-reprodutivo variou de 0,89 dia (25°C) a 3,72 dias (15°C). A longevidade do afídeo diminuiu com o aumento da temperatura, de 23,95 dias (15°C) para 5,06 dias (25°C). Temperaturas entre 15 e 20°C são mais favoráveis a M. persicae.

Abstract:

Abstract An insecticide-susceptible strain of GPA (S) cultured under insecticide-free conditions for several years and a multiresistant strain (M-R) were tested. Strain M-R was field collected from a peach and nectarine orchard sprayed with twice the recommended rate of Pirimor. Prior to testing, both strains were maintained on potted cabbage in a mass culture laboratory under natural light at 25 ± 4°C. Neither strain had been previously exposed to NTN-33893, a nitromethylene. Initial laboratory screening categorized strain M-R with a 4 fold resistance to Monitor 580 (580 g/liter EC), a 17 fold resistance to Pirimor (500 g/kg W) and a 27 fold resistance to Meta- Systox (i) (250 g/liter EC) compared to strain S. Electrophoretic examination showed that 50 M-R individuals consisted totally of the R2 variant. Aphids were exposed to NTN-33893 by spraying directly with a 2 ml aliquot solution through a Potter spray tower producing a deposit of 1.6 mg/cm2. Apterous virginoparous adults from both strains were sprayed with a range of serially diluted concentrations of NTN-33893 (200 g/liter soluable liquid) in groups of 12-15 aphids on a 9 cm filter paper discs. Eight replicates were done at each concentration for strain S except the 8 mg/liter concentration which had 4 replicates. Four replicates were done at each concentration for strain M-R. All replicates included water-only sprayed controls. After being sprayed, aphids were transferred to cabbage leaves and held at 22°C ± 1°C under constant illumination. Knockdown, defined as the inability to walk in a coordinated manner, was assessed after 48 h and log dose probability (ld-p) curves were calculated using probit regressions after correcting for control mortality. Ld-p curves were compared to the KD50 level by relative potency analysis. Residual deviances were calculated and the changes in deviance compared to the relevant 5% value of X2 to determine if the lines were parallel.

Abstract:

AbstractResponse to the alarm pheromone, (E)-β-farnesene, produced by many species of aphids, was assessed in laboratory bioassays using an aphid pest, Myzus persicae (Sulzer), and its primary endoparasitoid, Diaeretiella rapae (McIntosh). This was done in three separate studies, the first investigating responses of a large number of M. persicae clones carrying different combinations of metabolic (carboxylesterase) and target site (kdr) insecticide resistance mechanisms, and the other two investigating the responses of young virgin female adult parasitoids. In M. persicae, both insecticide resistance mechanisms were associated with reduced repellence suggesting that each has a pleiotropic effect on aphid behaviour. In contrast, D. rapae females were attracted to the alarm pheromone source. The implications of this apparent fitness trade-off for the evolution and dynamics of insecticide resistance, and the potential for using beneficial insects to combat resistance development are discussed.

Abstract:

Aphids are sap-sucking insects that mainly attack shoots and young leaves of peach trees and many other plant species; however, knowledge of the Brazilian aphid fauna is scant. The objective of this study was to identify aphid species collected in peach orchards (Prunus persica Batsch) and to determine their faunal indices for occurrence and dominance. The experiment was conducted from July 2005 to September 2006 in six Chimarrita peach orchards in the municipality of Araucária, PR, Brazil. The survey of aphid species was conducted by visual samplings on peach trees and using Möericke-type yellow traps containing water. A faunal analysis was made using aphid occurrence and dominance indices. Brachycaudus persicae (Passerini, 1860) was the only aphid species that was found colonizing peach in Araucária/PR. Although most aphids collected were classified as rare, some can be considered potential peach colonizers, such as Myzus persicae (Sulzer, 1776) which was given the status of common or intermediate in some of the orchards studied. The population fluctuation of aphids showed a negative correlation with rainfall and positive correlation with temperature and relative humidity.

Abstract:

AbstractResidues of pirimicarb or deltamethrin plus heptenophos on potatoes in field cages in southern England reduced artificial infestations of susceptible and insecticide-resistant strains of Myzus persicae (Sulzer) introduced up to 14 days after treatment. Deltamethrin plus heptenophos gave better control than pirimicarb, particularly of nymphs, but also selected more strongly for very resistant (R2) aphids. Susceptible (S) aphids survived the treatment with deltamethrin plus heptenophos better than moderately resistant (R1) aphids, probably due to a different or more pronounced behavioural response to the pyrethroid. However, the combination of the greater persistence of deltamethrin plus heptenophos and the high resistance of M. persicae to the pyrethroid led to more prolonged selection for R2 aphids, which is sometimes associated with a resurgence in aphid numbers.

Abstract:

Excessive insecticide application has posed a threat to pollinators and has also increased insecticide resistance of Myzus persicae Sulzer. Therefore, it is urgent to develop an economical and effective strategy, especially for greenhouse vegetables. Firstly, we selected a neonicotinoid insecticide that is specifically fatal to M. persicae but relatively safe to predators and bumblebees by laboratory toxicity tests and risk assessments. Then, we tested the effectiveness of the neonicotinoid insecticide under different temperature conditions. According to the LC50 values and the hazard quotients, thiacloprid met the requirements. Greenhouse trails indicated that thiacloprid was quite efficient, while control dropped to 80% without the application of thiacloprid. As for biological control, Harmonia axyridis effectively controlled 90% of aphids with thiacloprid or not. However, Aphidoletes aphidimyza performed better above 20 °C. Our results indicated that it is cost-effective to control M. persicae with A. aphidimyza in suitable temperature conditions and H. axyridis was more effective at low temperatures. Practically, thiacloprid could be used either as an emergency option to control aphids’ abundance alone or in combination with natural enemies.

Abstract:

The green peach aphid, Myzus persicae Sulzer (Hemiptera: Aphididae), a polyphagous insect pest is a major threat to a wide range of crops worldwide. Aiming to evaluate the life history traits of M. persicae, feeding on different host plants, we used five vegetables: cabbage, Brassica oleracea (Brassicaceae); chinese cabbage, B. rapa (Brassicaceae); chili pepper, Capsicum annum (Solanaceae); crown daisy, Chrysanthemum coronarium (Asteraceae); and eggplant, Solanum melongena (Solanaceae). TWOSEX-MSchart software was used for the statistical analysis about the age-stage, two-sex life table theory. The highest fecundity (69.65 individuals) rate of M. persicae, intrinsic rate of increase (r = 0.425 d−1), finite rate of increase (λ = 1.531 d−1), net reproductive rate (R0 = 69.65 offspring), and shortest mean generation time (T = 9.964 d) were recorded on the chili pepper plant. Whereas, lower fitness occurred on cabbage. The findings attained from population growth parameters indicate that chili pepper is the most susceptible plant, while cabbage is resistant to aphids. Population projection results also supported this statement, as the final total population size on cabbage was significantly lower than other plants. The reported information would be useful for devising integrated pest management programs, particularly those involving M. persicae. This information also suggests the adaptability of M. persicae causing economic damage to these vegetable cultivars.

Abstract:

The whitefly, Bemisia tabaci (Gennadius) and the aphid, Myzus persicae (Sulzer) are important pests in tomato and chilli pepper. These pests directly attack and as a viral vector can decrease the production of tomato and chili pepper. Menochilus sexmaculatus (Fabricius) and Micraspis lineata (Thunberg) are predator beetles of B. tabaci and M. persicae. This study aimed to know the potential predation of M. sexmaculatus and M. lineata as a predator of B. tabaci and M. persicae. Completely randomized factorial design using 2 factors consist of type and density of prey with 3 replicates used in this study. The potency of predatory coccinellidae as predator of B. tabaci and M. persicae was evaluated in 2 observations, i.e. predation and functional response assay. Based on logistic regression analysis, both of M. sexmaculatus and M. lineata showed characteristic of type I functional, this means that the higher density of prey, the ability and predation rate of M. sexmaculatus and M. lineata were also increased. The predator M. sexmaculatus and M. lineata were more effective to control M. persicae than B. tabaci. M. sexmaculatus was the effective predator to control adult of M. persicae.
