The experiments were conducted in Plant Protection Research Institute, Sharkia branch, Agriculture Research Center to study the toxic and biological effects of phenol compound against the pink, spiny and American bollworms under controlled conditions of (26 ± 1 C° and 70 ± 5 % R. H.). Data revealed that phenol compound had highly toxic effect on the eggs of the spiny followed by pink then American bollworms, but the highest toxic effect against newly hatched larvae attained against the American followed by pink then spiny bollworms larvae. On the other hand, the latent effects of the phenol compound on the three insect species were presented in increasing the accumulated mortality of larval and pupal mortality percentages, non significant increasing on larval duration of the three cotton bollworms insects, and significantly decreased in larval and pupal weight, increasing pre and post-oviposition periods, decreasing oviposition periods, male and female longevities and also reduced fecundity, while the highest reduction in laid eggs recorded on pink followed by American then spiny bollworms compared with untreated control, while the hatchability percentages decreased significantly with pink bollworm and non significant with spiny and American bollworms compared with untreated control.

Little is known about which commercial vegetable oils could be used as an ingredient in improving artificial feedstuffs for honey bees. To test whether the oils are palatable or whether honey bees showed a preference, they were added at 1% and 2% concentration to pollen substitute known to be attractive to bees. Seven different vegetable oils, only linseed was consumed by bees at a significantly greater rate than others followed by almond and coconut. Other oils added to pollen substitute that had higher consumption rates by colonies than pollen substitute without oil were (highest to lowest): corn,
Soybean, Palm and sunflower oils. Obtained results show the superiority of diet consumption for the workers which feed on pollen substitute containing linseed oil at 1 and 2% concentrations (109.43 and 110.11 mg), respectively over any all other oils and control. The percentages of deviation from control (without oil) (+ 68.43, 69.46), (+55.70, 57.27), (+ 55.37, 56.56), (+35.59, 36.78), (+26.20, 27.18), (+21.94, 23.03) and (+11.54, 11.98) were recorded in case of linseed, almond, coconut, corn, soybean, palm and sunflower oils at 1 and 2 % concentrations, respectively.

Estimate the losses of honey bee colonies are an important measure of honey bee health and productivity. This study records the data of two years, 2011/2012 and 2012/2013 survey of losses in managed honey bee colonies in New Valley Governorate. The survey of colony losses and potential causes was obtained via questionnaire method. The surveyed beekeepers had loss a total of 373 colonies between September and March each year. Colony loss percentages were 35.5% in 2011/2012 and 38.8% in 2012/2013. Survey information indicated that colony losses range widely depending on the operation size of the beekeepers. Hobbyist beekeepers (≤ 15 colonies) and intermediate beekeepers (16-50 colonies) lost the lower number of colonies as compared to semi-commercial beekeepers (those operating more than 51 - 100 colonies). Oriental hornets, starvation, Varroa mite, CCD-like symptoms and poor quality queens were the leading self-identified reasons of losses as reported by most beekeepers. Finally, it must circulate such as this questionnaire over all Egypt to understand the extent of the problem and try to find out the resolve.

Choice and non-choice tests were carried out to determine the influence of certain maize varieties on the rice weevil, <em>Sitophilus oryzae</em> (L) infestation under laboratory conditions. Regarding to non-choice tests on different maize varieties, data revealed that, Tri-Hybrid 353 yellow variety was the highest weight after damage. while Tri-Hybrid 311 white variety was the highest percentage weight loss and lowest weight after damage. In addition, Tri-Hybrid 353 yellow variety was the longest total developmental period and lowest number of F1 while Tri-Hybrid 311 white variety was the shorter total developmental period and highest number of F1 progeny. In respect to free choice on different maize varieties, data revealed that, Tri-Hybrid 353 yellow variety was the highest weight after damage, while Tri-Hybrid 311 white variety was the highest percentage weight loss and lowest weight after damage. On the other hand, the index of susceptibility (IS) among the varieties tested showed that Tri-Hybrid 311 white was moderately susceptible for different maize grains varieties and other varieties were moderately resistant.

Relative susceptibility of thirteen faba bean genotypes compared to local variety Sakha1 to leafhoppers, <em>Empoasca</em> spp. with regard to their associated predators were evaluated at Sakha Agricultural Research Station Farm, Kafr El-Sheikh under two sowing dates (the first week of October and the first week of November) during two growing seasons being 2010/11 and 2011/12.
Judging by the grand mean of leafhoppers of the two successive seasons, statistical analysis revealed insignificant differences among the tested genotypes to the leafhoppers infestation, while there were significant differences for predators attraction for the first date plantation. Genotype H-240A harbored the highest mean number of predators, while the least mean number took place on genotypes H-1972B and H-1973. In respect to the second date plantation, genotypes H-232; H-1992; H-240A; H-1972B and H-230 exhibited the highest mean number of leafhoppers, while genotype H-1973 harbored the least number. The predators recorded the highest mean number on H-230, while H-240B exhibited the least mean number. However, five species of predators (<em>Crysoperla carnea (</em>Steph<em>.);</em> <em>Scymnus interuptus </em>(Goeze);<em> Paederus alfierii </em>(Koch); <em>Coccinella</em> spp. andtrue spiders) were found in faba bean field during the two seasons. The first species was the most dominant.
According to the resistance degree, genotypes H-240A and H-240B appeared moderately resistant; H-1970; H-1972B; H-1973; H-1988 and H-232 appeared relatively resistant; H-1972A; H-1992; H-243; H-244 and Sakha1 appeared susceptible and H-1980 and H-230 appeared as highly susceptible for the first date plantation. As for the second date plantation, H-1973 and H-243 appeared moderately resistant; H-1970; H-1988; H-240B and Sakha1 appeared relatively resistant; H-1972A; H-1972B; H-1980; H-230 and H-244 appeared susceptible and H-1992; H-232and H-240A appeared highly susceptible.
Finally, it could be stated that, faba been genotypes H-240A and H-240B are considered promising genotypes for the first week of October plantation, while H-1973 and H-243 are suitable to the first week of November plantation. Thus, the tested genotypes must be taken great attention in the future to be used as relatively resistant varieties against leafhoppers infestation.

Nine of flax genotypes were tested in Etay El-Baroud Agric. Res. Station, ARC, Egypt, in 20010/11and 2011/12 winter seasons to study their morphological manifestations and insect infection of some flax genotypes. Comparisons among genotypes, also, were made to find out their variability in seed yield and its components. All genotypes were tested in lab. before planting for standard germination, accelerated ageing, electric conductivity, seedling growth and chemical characters.Giza8 genotype gave the highest dry weight / plant after 75 and 90 days from sowing, while, S 533/39/5/11 was the lowest genotype, at harvesting time, Giza 8 genotype was superior over all flax genotypes in total plant height, technical stem length, and fiber yield /faddan. While, S413/1/3/2 ranked first, regarding such characters, with the exception of seed yield and its components. S533/39/5/11was superior in oil %, compared to the genotypes under study. Phenotypic and genotypic variance recorded high estimates in seed yield / faddan, number of seeds/plant, oil yield / faddan, fiber yield / faddan and was slightly high in total plant height. On the other hand, straw yield / faddan and seed yield per plant had the lowest estimates. Heritability values, in broad sense, were high in magnitude for seed oil percentage, 1000 seed weight, total plant height and oil yield / faddan. While, number of capsules and seeds/plant and seed yield/plant showed higher levels of expected genetic advance from selecting the top 5% of superior individuals. . Also, during seasons of experimentati Six genotype were chosen to evaluated of infestation with the aphids, Green bug<em> Nezara viridula</em> L. and the mean percentage of infestation by The cereal tortrix moth <em>Cnephasia sp</em>. The mean values of infested by three insects showed that, the genotype Escalina was the most significant susceptible to <em>aphids </em>infestation followed by Sakha2 ,Giza8, Marlir, Sakha1 and Sakha3. Also Escalina genotype was the most significant susceptible to Green bug<em> N. viridula</em> followed by Giza8, Sakha1 , Sakha2, Sakha3, and Marlin more over than, Escalina genotype was higher percentage of infestation by The cereal tortrix moth <em>Cnephasia sp</em>. followed by Giza8, Sakha1, Sakha3, Marlin and Sakha2. Moreover than, non significant correlation were found in three insect infestation with six genotypes on yield components. Except in case of % Oil with <em>N. viridula</em> which showed negative correlation
