This investigation was carried out at the experimental farm of Sakha Agricultural Research Station, during wheat growing seasons from 2009 to 2011. The objectives were to study the inheritance of adult plant resistance to stripe rust Puccinia striiformis f. sp. tritici [Pst] in the two Egyptian bread wheat cultivars Giza160 and Giza168 and identification of the most effective Yr genes under study. Two Egyptian wheat cultivars (Triticum aestivum L.) i.e., Giza168 (resistant) and Giza160 (susceptible) to strip rust were crossed to four monogenic lines (Yr’s) i.e., Kalyansona, Lee, Compair, and Jupateco R, which having strip rust resistance Yr's gene(s); Yr2, Yr7, Yr8 and Yr18+, respectively. Yellow rust reaction of the two cultivars and monogenic lines and their F1 and F2 populations were scored under field conditions. Artificial inoculation was done using mixture of physiological races of [Pst] at adult stage. Dominance of yellow rust resistance over susceptibility was noticed in most cases (in four out of five resistant by susceptible crosses). Segregation in the F2's population showed the presence of two to three gene pairs controlling plant reaction against the [Pst]. The Yr8 gene had high effectiveness of conferring resistance against [Pst] under this investigation. Meanwhile, broad sense heritability estimates was high, thus early generation selection for stripe rust resistance could be effective for wheat improving for this character.

Two field experiments were conducted to study the effect of foliar application with different concentration of different types of organic materials on the mobile stages of Tetranychu surticae infesting soybean plants. The experiments were conducted in randomized complete block design with13treatments during the two successive seasons (2013& 2014) at Qalubiya Governorate. The soybean plants were sprayed with 6 successive sprays, 15 days between each spray.The three lupines terms extract (L.T.Ex.) concentrations (0.01; 0.02 & 0.03%) gave good effects against the mobile stages of T. urticea.Also, results show that the bio organic liquid tea manure (M.Tea) with two concentration (5 & 10%) gave good effects against the mobile stages of T. urticae.On the other hand, mixed of lupines terms extract with three concentrations and M.Tea with two concentrations, gave good effects against the mobile stages of T. urticae comparing with unmixed compounds and its concentrations and recommended compound (Vertimic).Data show that the highest reduction of the mobile stages of T. urticea was 97%, as mean value, by M.Tea at the rate of 10% + L.T.Ex. at concentration of 0.02% or 0.03% when comparing with control. Vertimic gave 96% after 6 successive sprays against the mobile stages of T. urticae. In the second year, similar results are obtained with some exceptions. Statistical analysis show significant differences between the 12concentrations of the tested natural compounds and recommended compound (Vertimic) against the mobile stages of T. urticae.

The ovicidal action of three novel compounds (emamectin benzoate, methoxyfenozide, pyridalyl) and conventional insecticide (methomyl) against (0-24, 24-48 and 48-72 hours age) eggs of Spodoptera littoralis was assessed. The toxic activity of emamectin benzoate, methoxyfenozide, pyridalyl and methomyl against 4th instar larvae of laboratory and field strains of S. littoralis were carried out. Also, the build up of resistance of each tested compound in the field strain was calculated. The joint toxic action of emamectin benzoate, methoxyfenozide and pyridalyl with tested insecticides was also studied. The obtained data revealed that emamectin benzoate gave an ovicidal activity higher than methomyl, methoxyfenozide and pyridalyl. Also, emamectin benzoate was a superior potent compound against 4th instar larvae of S. littoralis followed by methoxyfenozide, with LC50 values were 0.007 and 0.932 ppm after 72 hrs, while methomyl was the least toxic one, LC50 value was 95.60 ppm. The build up of resistance of tested compounds indicated that the resistance ratio of methoxyfenozide and methomyl were 5.9 and 5.8 fold as the laboratory strain, while the resistance ratio of emamectin benzoate and pyridalyl were 2.7 and 1.9 fold as the laboratory strain. In respect with the joint toxic action, the all mixtures of the tested insecticides showed highly antagonisms effect as calculated by the co-toxicity factors. The present study suggests that emamectin benzoate is very effective in the control of S. littoralis.

Aphelinids (Hymenoptera : Aphelinidae) are the most important parasitoids of, armored scale, soft scale insects ( Hemiptera: Coccoidea ) and whiteflies ( Hemiptera: Alyerodoidea). The present work dealt with the diagnosis and abundance and the role of this group in controlling armored scale, soft scale insects and whiteflies. The results indicated that 17 parasitoids and hyperparasitiods were reared from samples of armored , soft scale insects and whiteflies in different locations in Egypt. These parasitoid and hyperparasitiod species were collected from 7 armored, soft scale insects and whiteflies and distributed in 5 Governorates (Alexandria, Assuit, Ismailia, Fayoum and Matruh). The maximum rate of parasitism of armored scale insects parasitoids ranged between 12-59% during the two years under consideration. While the maximum rate of parasitism of soft scale insects and whiteflies parasitoids ranged between 13-28% and 39-58%,. during the two years under consideration, respectively. This result indicated that some parasitoids of armored, soft scale insects and whiteflies were effective in controlling them

The present study was carried out to evaluate two naturalyte biocides, spinosad and ivermectin, one recommended chemical synthetic insecticide, malathion as reference against three important insects of stored grain, Sitophilus oryzae, Rhyzopertha dominica and Tribolium castaneum. Results obtained show that rates of spinosad or ivermectin from 50-150 ppm and rates of malathion from 1-4 ppm completely prevented emergence of adults of S.oryzae and followed that increase the reduction of progeny to 100%. R.dominica has the same trend with S.oryzae, but the R.dominica was more susceptible to biocides and insecticide tested than S.oryzae, which gave high mortality ranged from 81-100% at all concentrations. T.castaneum was more tolerant than the other tested insects. At the all rates of tested materials, the percentage loss weight of wheat decreased in comparison with control. In generally, R.dominica was the most susceptible to the tested materials followed by S.oryzae and T.castaneum . S.oryzae adults exposed to wheat grain diet received half-dose of 50 ppm spinosad or ivermectin, separately gave 96 and 88% mortality after two weeks of exposure, while the one-third dose gave 90 and 63% mortality. The high levels of both spinosad or ivermectin nearly completely prevented the F1 progeny of S.oryzae in half and one third dose. R.dominica was higher affected than S.oryzae at the same levels of spinosad and ivermectin where spinosad at the all levels of half dose completely prevented the F1 progeny of R.dominica while with the one-third dose the % reduction values ranged from 82.3 to 100%.
