AbstractThe effects of the horticultural oil Purespray Green on oviposition behaviour and egg development in the obliquebanded leafroller, Choristoneura rosaceana (Harris), were investigated through dual-choice and no-choice bioassays and topical applications of oil to developing eggs. A residual 2% (v/v) oil spray on wax-paper and apple-leaf substrates significantly reduced both the number of eggs laid and egg survival in no-choice assays; however, this effect diminished 3 days after treatment. In dual-choice assays, females laid significantly fewer eggs on oil-treated apple leaves than on control leaves, but laid equal numbers of eggs on the oil-treated wax paper and the untreated wax-paper controls. Topical application of oil caused significant dose-dependent mortality of both newly laid eggs and eggs just before hatch, and these two egg stages were equally susceptible to the oil. Topical application of 2% oil caused >99% egg mortality. Our data indicate that gravid female C. rosaceana can assess and reject oil-sprayed surfaces and that the oil can kill eggs through both contact toxicity and suffocation. These characteristics suggest that highly purified horticultural oils like Purespray Green could play a role in an integrated pest management program for this important pest species.

The paper summarizes results of the study of the occurrence, development and harmfulness of Phratora (= Phyllodecta) vitellinae (L.). The majority of studies was carried out in 1998 to 2005 in riparian and accompanying stands of the Svitava and Svratka rivers in the region of Brno and in a laboratory. Imagoes leave hibernation hiding places at the end of April and at the beginning of May. In captivity, they lived on Salix fragilis about 2.5 months damaging on average 28.6 cm<sup>2 </sup>leaf blades and laying on average 293 eggs. In the excessively warm growing season of 2005, imagoes lived about 3.5 months after hibernation, however, already after one month of feeding they fell in a month diapause at the beginning of June. Before its start, they damaged on average 12.8 cm<sup>2</sup> (after the diapause 14.4 cm<sup>2</sup>) leaves and laid on average 389 eggs (of this number, 260 eggs before and 129 after the diapause). Larvae damage about 4 cm<sup>2</sup> leaves during 2 to 3 weeks (in the laboratory during 12 to 13 days). After 2 to 3 weeks (in the laboratory after 10 to 12 days) from the cessation of feeding young beetles appear on trees. Imagoes of the 1<sup>st</sup> generation occur from mid-June to the beginning of October. During about 55 days of life, they damaged 19 cm<sup>2 </sup>leaves and laid on average 182 eggs. Imagoes of the 2<sup>nd</sup> generation occur from mid-August to the end of the growing season. After 10 to 14 days of feeding (without previous copulation), they take shelter in wintering places. In the laboratory, however, these imagoes damaged about 19 cm<sup>2</sup> leaves during 2 months and laid about 190 eggs. Wintering places were looked up by imagoes of the 3<sup>rd</sup> generation which damaged on average 4.2 cm<sup>2 </sup>leaves before hibernation. In the Czech Republic, P. vitellinae is usually bivoltine the 2<sup>nd</sup> generation being always incomplete.

AbstractThe influence of diet on oviposition and survival of Forficula senegalensis Serville was studied in laboratory conditions using four different regimens: millet leaves and stems, lepidopteran eggs and larvae, millet pollen, and no food at all. Four parameters were monitored: female weight, survival time, time to oviposition, and number of eggs produced. Starving females and females fed millet leaves and stems lost weight and survived for an average of 30–40 days without any of them laying eggs. Females fed millet pollen or lepidopteran eggs and larvae gained weight and survived for more than 60 days. Forty percent of the females fed pollen laid an average of 49 eggs the first time, and 50% of those fed lepidopteran eggs and larvae produced an average of 67.5 eggs. In both cases, less than 2% of the females oviposited a second time (average of 30 eggs). Earwigs fed lepidopteran eggs and larvae oviposited sooner. A diet of millet leaves is insufficient for oviposition in F. senegalensis; females need a richer diet based on pollen or animal preys in order to lay eggs.

In 2003 to 2005, Chrysomela populi L. gradated on yearly cut Populus nigra var. italica in street alleys in Brno and elsewhere. Imagoes occurred on trees from the end of April or from the beginning of May. In rearing, the chrysomelid consumed unwillingly leaves of 2-year shoots and laid on average 142 eggs. On leaves of shoots, imagoes damaged 100 to 200 cm<sup>2</sup> during 5 to 7 weeks, produced 480 to 900 frass pellets and laid on average 506 eggs. Oviposition was continual with breaks amounting to on average 2.6 days. Embryonal development took 6 to 8 (in the laboratory 5) days. Larvae of the 1<sup>st</sup> generation occurred from mid-May to mid-July. In the course of 2 weeks (in the laboratory during 10 days) of life, they damaged about 20 cm<sup>2</sup> leaves and produced about 300 frass pallets. In the laboratory, prepupae took 2 days and pupae 4 days. Imagoes of the 1<sup>st</sup> generation occurred from June to September. They damaged on average 113 cm<sup>2</sup> and produced on average 553 frass pellets and 653 eggs. At a temperature of 24 to 28°C, imagoes damaged on average 84 cm<sup>2 </sup>during 2 to 3 weeks and diapaused until the next year. On growing up leaves, imagoes lived longer showing higher consumption of food and higher fecundity as against new fully-grown leaves. Larvae of the 2<sup>nd</sup> generation destroyed on average 2 cm<sup>2 </sup>smaller area than larvae of the 1<sup>st</sup> generation. Part or all imagoes of the 2<sup>nd</sup> generation diapaused. Imagoes of the 3<sup>rd</sup> generation damaged 40 to 70 cm<sup>2</sup> leaves before departure to wintering grounds. In our natural conditions, the prospective 3<sup>rd</sup> generation is always incomplete. Cleonice callida Meig. and Schizonotus sieboldi (Ratz.) rank among important enemies.

AbstractPrincipal components analysis was used to assess niche partitioning between four aphid predators on the basis of oviposition strategies. The study was conducted by sampling abundance and position of the eggs of these predators in corn monocultures in two locations of southern Quebec. The results indicated that the chrysopid Chrysopa occulata Say laid its eggs on corn leaves usually without aphid colonies, and late in the season. All other predators reacted to aphid concentrations. The syrphid Sphaerophoria philanthus (Mg.) oviposited close to the ground, early in the season, and among colonies of the aphid Rhopalosiphum padi (L.). The two coccinellids laid their eggs during July and August with a maximum during tasseling for Coleomegilla maculata lengi (Timberlake) and after pollination for Hippodamia tredecimpunctata tibialis Say. Of these two species, the latter one selected sites at higher levels on the plant, and was more abundant at the edges of the field. It is suggested that the observed niche partitioning cannot be the result of interspecific competition in variable environments such as maize monocultures.

Abstract The experiment was conducted at the Rock Springs Research Farm. The study was laid out as a completely randomized design with 7 treatments each replicated 4 times. Treatments consisted of 5 plants, spaced 3 feet apart. Data were obtained from samples taken from the center section of plots. Each plot was rated for potato leafhopper damage on leaves. A toxicity index to assess damage was created on a scale of 0-3: 0 = no visible damage; 1 = 2% of leaves curled; 2 = 50%-75% of leaves curled; 3 = >75% of leaves curled. On 16 Jun, treatments were applied using a CO2 Precision Boom Sprayer that delivered 72 gal/acre at 35 psi. The spray boom was equipped with twin fan nozzles (T.J. 60-1104 vs). On 18 Jul treatments were applied using a Meyers Boom Sprayer that was adjusted to deliver 72 gal/acre traveling 3 mph. Treatments in parentheses were applied previously on 25 May.

Oviposition site selection by herbivores can depend not only on the quality of host resources, but also on the risk of predation, parasitism and interference. Females of the lycaenid butterfly Arhopala bazalus (Lepidoptera) lay eggs primarily on old host foliage away from fresh growth, where larval offspring live and feed. Resource availability of young host leaves seems not to affect the oviposition site preference by the females. To clarify the adaptive significance of A. bazalus oviposition behavior on old foliage, we tested three hypotheses: eggs on fresh foliage are (1) easily dropped during rapid leaf expansion (bottom-up hypothesis), (2) more likely to be attacked by egg parasitoids (top-down hypothesis), and (3) frequently displaced or injured by other herbivores (interference hypothesis). In field surveys, rates of egg dropping and parasitism by egg parasitoids were not significantly different between fresh and old host parts. However, the portions of fresh leaves on which A. bazalus eggs had been laid were cut from shoots on which conspecific larvae fed. Laboratory experiments demonstrated that eggs on young leaves were displaced in the presence of conspecific larvae and we observed that fifth instar larvae actively displaced conspecific eggs by feeding on the surrounding leaf tissue. These findings indicate that eggs laid on fresh leaves are at risk of being displaced by conspecific larvae, and support the interference hypothesis. Larval behavior is a likely evolutionary force for A. bazalus to lay eggs apart from larval feeding sites on the host plant.

The present study was carried out in the glasshouse of the Department of Biology, College of Science, Salahaddin University- Erbil, and laboratories of Research Center in Erbil Polytechnic University, from April 21st, 2019 to July 26th, 2020, to determine the eff ects of foliar application of nitrogen (N1:100, N2:200, and N3:300 kg. h-1) and magnesium (Mg1:0.0, Mg 2:30, and Mg3:60 kg. h-1) applied under two diff erent soil moisture contents (SM1:100% fi eld capacity (FC) and SM2: 60% FC) on some physiological properties and yield quality of rosemary plants (Rosmarinus offi cinalis L.). A factorial experiment was laid out according to a completely randomized design with four replications. Two cuttings were taken from the rosemary shoots (in March, and July, 2020). Results showed that SM2 decreased phenolic compounds in cut 1 (cut 1), dry matter percent in leaves in cut 2 and relative nitrogen yield in cut 1, cut 2 & cut 1+2. N3 increased dry matter in leaves shoots in cut2 signifi cantly, proline, phenolic compounds in leaves, stress tolerance index (STI), modifi ed stress tolerance index 1(MSTIK1), & modifi ed stress tolerance index 2 (MSTIK2). The interaction treatment SM2Mg2 increased the proline content in dry leaves. The proline content was increased by the triple interactions SM2N3Mg2 and SM2N3Mg3.

The article presents the results of studies of the biomorphological features of cannas in arid conditions. It was found that the varieties differ in the height of shoots and their number, the number of leaves and flowers on the shoots, the number of renewal buds formed by the end of the growing season. On one shoot of the Crozi cannas varieties, 2-4 renewal buds are laid, of which 1-2 shoots develop. All varieties are characterized by: the effect of the size of the 1st assimilating leaf on the total number of leaves is observed only on the first order shoots; an increase in the height of shoots with an increase in their order; a decrease in the number of leaves with an increase in the order of shoots; in the conditions of the Karshi oasis at an elevated air temperature (average ten-day values from +26.7 to + 33.4°С) in June-August - there is an increased growth and development of the aboveground part, with a decrease in temperature (to 19.5°С) from the end of September - underground.

Studies were conducted to determine the effects of moisture stress and schleffera variety (Brasspia actinophylla Endl. and B. actinophylla ‘Amate’) on populations of twospotted spider mides (Tetranychus urticae Koch) grown under interior conditions. After approximately 2 weeks, spider mite populations were significantly higher on moisture stressed B. actinophylla as compared with unstressed plants. Populations on rewatered plants were intermediate. Moisture stress did not affect mite populations on the cultivar ‘Amate’ in a consistent manner. The cultivar ‘Amate’ was more mite resistant than B. actinophylla. Mites feeding on ‘Amate’ laid fewer eggs, had lower survival and slower developmental rates than those feeding on B. actinophylla. Leaves of ‘Amate’ were 67% thicker and had lower percent total nitrogen than B. actinophylla leaves.

The word aphrodisiac comes from the name of Aphrodite, the Greek goddess of sexual love, fertility, and beauty. An aphrodisiac is any drug that arouses the sexual instinct. Throughout recorded history, humans have gone to great lengths in pursuing enhancement of sexual activity and desire. In Shakespeare’s Midsummer Night’s Dream (II, i), Oberon begged for the love potion:… Fetch me that flower; the herb I show’d thee once: The juice of it on sleeping eyelid laid Will make a man or woman madly dote Upon the next live creature that it sees… Perhaps the best-known aphrodisiac is alcohol, which was recognized thousands of years ago for its possible aphrodisiac properties. Shakespeare described the effect of liquor through the porter in Macbeth (II, iii):… Lechery, Sir, it provokes, and unprovokes; It provokes the desire, But it takes away the performance. Therefore much drink may be said to be an equivocator with lechery; It makes him, and it mars him; It sets him on, and it takes him off; It persuades him, and disheartens him; Makes him stand to, and not stand to; In conclusion, equivocates him in a sleep, and, Giving him the lie, leaves him…. Aphrodisiacs are not a mere recreational curiosity in medicine; they may genuinely help some patients on antidepressants who suffer decreased libido as a side effect. According to the mechanisms of action, libido lifters can be divided into seven categories:… 1. Serotonin antagonists: cyproheptadine and granisetron 2. Adrenergic antagonists: yohimbine and trazodone 3. Cholinergic agonists: bethanechol chloride 4. Dopamine-enhancing drugs: bupropion, amantadine, and bromocriptine 5. Autoreceptor agonists: buspirone and pindolol 6. Stimulants: amphetamine, methylphenidate, and ephedrine 7. Herbals: ginkgo biloba and L-arginine… Aphrodisiacs can be obtained from plants and animals or made through chemical synthesis. Although many aphrodisiacs have not been rigorously proven effective in clinical trials, in reality, a psychological boost is likely enough to help, because many sexual problems are “in the mind” anyway.

The use of chemical fertilizers as a supplemental source of nutrients has been on the increase but they are not applied in balanced proportion by most farmers [1]. Also, fertilizer requirements of the mixed intercropping systems have been a matter of conjecture; some studies had suggested that fertilizer requirements of the dominant component be applied [2], others recommend that the sum of the sole crop requirements, be applied [3]. Teriah [4], however, stated that both practices have proved either inadequate or wasteful. In this experiment the effects of different rates of NPK 15-15-15 fertilizer application on growth and yield of hot pepper and Egusi melon in an intercropping system was examined to determine optimum rate for production. The experiment was carried out at the Teaching and Research Farm of the Federal University of Agriculture Abeokuta, in the south western part of Nigeria. It took place from March to October 2017 during the growing season. The experiment was laid out in a Randomized Complete Block Design (RCBD) with 5 treatments (fertilizer rates) and 3 replicates. Treatments were; 0, 100, 200, 300 and 400 kg/ha of NPK 15-15-15 applications. Plot size was 3m by 3m with a 1.5m gang way round each plot to reduce inter-plot effect. Data were collected on growth parameters at 6 weeks after treatment (WAT) and continued at two-week intervals until 10 WAT. Four plants each of pepper and Egusi melon from the inner rows were randomly selected and tagged for the purpose of data collection. Data on yield were also collected at ripening. Analysis of variance (ANOVA) was carried out on each observation and the Least Significant Difference (LSD) was used for means separation (P≤0.05). The effects of fertilizer rates showed significant difference on pepper plant height, number of leaves, number of branches and leaf area. However, there was no significant difference in the effect of fertilizer rate on days to 50% flowering of pepper. Number of vines and vine length of Egusi melon were significantly different in their responses to fertilizer rates but the leaf area and days to 50% flowering of melon were similar at the various treatment levels. Meanwhile, total fruit yield of pepper, number of Egusi melon pods per hectare and the dry matter yield of Egusi melon showed significant difference. It was concluded from the study that the growth and yield of pepper and Egusi melon in intercrop increased with increase in fertilizer rate up to 400Kg/ha of NPK (15:15:15). However, higher fertilizer application rates should be explored in future studies for a better yield increase. These studies should be carried out with various compositions of inorganic and organic fertilizer application rates to ensure sustainable fertilizer application and to also preserve the natural fertility of the soil.
