The red palm weevil (RPW), <em>Rhynchophorus ferrugineus</em>, (Olive.) (Coleoptera: Curculionidae) is considered destructive insect pest of the date palm trees plantations of different Governorates in Egypt. The field experiments were carried out in Abo-Hammad district, Sharkia Governorate, Egypt, during successive years 2018-2019. Results indicated that the infestations of RPW were existed in two farms. The percentage of infestation reached to 6.73% in the first season, 2018 while reached to 4.76% in the second season, 2019. The percentage of infestation of severity both seasons cleared that most the infestations were highly severity. The highest infestation was found in Zaghloul variety followed by hayani, while the weakest infestation was in the varieties Aglan, Amry, Bent-Esha and Samani during the two seasons and the infestation of RPW in different ages of palms was the highest in young palms, that RPW preferred trees in age ranged between (6-10 years), while the lowest in age ranged between (10-15years). The infestation reached its maximum in the infested palms in the height ranged between 0.0-2.0 m., while it was minimum with infestation height from 2.1 to above 3.5 from the ground during the two seasons. The highest infestation of RPW were found in suckers , followed by of infestation in off-shoots, while it was decreased in the base of pruning leaves during the two seasons. Palm tree pruning without dusting with agricultural sulfur showed the highest infestation rate while, pruning of date palm and dusting with agricultural sulfur resulted in lower infestation rate during the two seasons.

About 470 bird species known from Egypt. The majority are non-breeding migrants, passing through the country, exploiting the wide range of habitat types unique for their life, including agricultural habitats. A survey of wild bird carried out in three agricultural districts, El-Badrasheen, El-Aayyat and El-Hawamdiah districts, in Giza Governorate, from March 2018 to February 2020, using the point transect method. Twenty-eight species belonging to nine orders and twenty-five families recorded. House sparrow (<em>passer</em> <em>domesticus niloticus</em>) and Hooded Crow (<em>Corvus corone cornix</em>) were the only recorded noxious species, damaging wheat and corn crops. House sparrow damage to wheat start after the first week of the panicles emergence causing 21.4 % and 19 % losses, with the highest loss rate of 5.7 and 6.1% during 1<sup>st </sup>of April at El-Badrasheen and El-Aayyat districts, respectively. The damage percent were 16.3 and 14.5% to corn by hooded crow in both districts from the 1<sup>st </sup>week of August up to the 2<sup>nd </sup>week of September and the highest loss rate were 5.4 and 4.2% during the 4<sup>th </sup>week of August in the two districts, respectively. It is advisable to apply damage control programs against house sparrow populations at the beginning of February in wheat fields, and against hooded crow populations at the beginning of June in corn fields in these areas.

This study focused to produce new resistant rice genotypes to major rice diseases and its highly productivity. Rice accessions Giza 177, Sakha 105, Sakha 106 and Gz.7768 were used as male parents and TG-60-6 lines were used as female parent in addition to F<sub>n</sub> lines obtained from four crosses. The best genotype has highly productivity and resistance to blast; TG-60-6/Sk.105-2, TG-60-6/Sk.106-3, TG-60-6/GZ.7768-2, TG-60-6/GZ.7768-5, TG-60-6/GZ.7768-6 and TG-60-6/GZ.7768-8. The results of yield and its compounds characters were influenced by environmental effect and the selection should be practiced successfully in late generation. Twenty four <em>Pyricularia</em><em> grisea</em> isolates were identified as five main groups<em>.</em> Under artificial inoculation eleven genotypes were resistant to all rice blast races, but at field condition, eighteen genotypes were resistant at Sakha location and twenty two genotypes resistant at Gemmiza location.The biochemical changes of antioxidant enzymes and total protein were estimated after 24, 96 and 120 h of inoculation with blast race p23 (ID-15) at seedling stage. The maximum activity of perioxidase (POX), polyphenol oxidase enzyme (PPO) and total protein was recorded at 96 h after inoculation and then decreased. Under artificial inoculation with <em>Bipolaris oryzae</em> the causal fungus of brown spot disease, TG-60-6/G. 177-1 and TG-60-6/GZ.7768-2 rice genotypes were the lowest for disease severity. For artificial inoculation with <em>Fusarium fujikuroi</em> the casual fungus of bakanae, TG-60-6/GZ.7768-1and TG-60-6/G. 177-8 rice genotypes were the lowest seedling death percentages. TG-60-6/G. 177-8 rice genotype was proved the lowest disease incidence. While, the rice genotype TG-60-6/Sk.106-1 showed the lowest disease severity index.

The harmful and beneficial effects of the land snail <em>Monacha sp < /em>. were studied in Sharkiah Governorate<em>.</em>Harmful effects were brightly observed in microbiological examination of gastropod and mucus in laboratory, and evaluating its damage on cabbage plant in laboratory and field. Microbial examination revealed that the gastropod was contaminated with (<em>Klepcella</em>) a harmful bacteria of man and animals and <em>(Burkhelderia ceptacia</em>) a non-useful bacteria in mucus. Few data were dealing with contamination of <em>Monacha </em>land snail in Egypt so, this study aims to highlight in this respect for taking into a sustainable infection when contact and thoroughly washing vegetables and fruits that are favorable food for <em>Monacha </em>land snails.Our results showed noticeable damage of cabbage leaves by <em>Monacha </em>snails in laboratory (26. 93%) and field (39. 23%) as a general mean value of cabbage consumption. Beneficial effects were revealed through biochemical analysis of both gastropod and shell components. Analysis revealed that <em>Monacha sp.</em>rich in protean (17.9%) and minerals such as calcium, phosphorus, magnesium and potassium. Calcium determined the highest (Ca, 13%), followed by phosphorus (Ph., 0.60%), magnesium (Mg, 0.12%) and potassium (K, 0.094%) so, the second aim of our study is the revealing of the economic feature of <em>Monacha </em>land snails as an addition to the fodder of farm animals and in traditional medicine.</em>

The present experiment was conducted in Zefta, Gharbia governorate to examine the influence of fertilization levels on the population density of the different leafhoppers and planthoppers attacking eggplant crop during the two successive seasons (2017and 2018). The potassium fertilization levels of zero kg/fed. to 25, 50, and 75 kg/fed. attracted the highest average number of the leafhopper and planthopper species during the two seasons. The present study indicated that increasing potassium fertilization rates from zero kg/fed. to 25, 50 and 75 kg/fed. led to a decline in the average number of the tested insect pests during the two years with significant differences. The potassium fertilization of 75 kg/fed. attracted the lowest percentage of occurrence of the tested insect pests and presented by 13.6 and 15.3 % during the two seasons 2017 and 2018, respectively.

The present study is conducted to investigate the supplementary effect of soy flour and spirulina as protein sources added to mulberry leaves with different concentrations (2.5, 5 & 10%w/v) on the biological, economical and physiological characters of three hybrids of silkworm, <em>Bombyx mori</em>; two imported hybrids (Bulgarian and Chinese) and the local Egyptian one (was used as a control or reference value). The schedule of application was applied since the beginning of the fifth larval instar till end up to spinning (one diet/day). Most of the studied treatments concentrations revealed a significant enhancement in the silkworm characters under investigation; a significant increase was exhibited in larval and pupal weight, cocooning percentage and the effective rate of rearing of the imported hybrids compared with the local one. Especially, larvae reared on the concentration 5% of soy flour then spirulina with the concentration 2.5%. Furthermore, the same concentrations of protein sources increased significantly the cocoon and silk filament characters. Moreover, the total protein content and protease activity of larval haemolymph exhibited a significant increase owing to rearing on mulberry leaves fortified with the same concentrations of protein additives respectively. Conclusively, soy flour as a high protein content nutritional additive with the tested concentrations is superior and better than spirulina. As well, silkworm larvae of the imported hybrids (Bulgarian and Chinese) are manifested more susceptive positively to protein nutritional additives than local hybrid. So, it could be prescribed to the breeding programs to achieve high quantity and quality of cocoon yield for silk production.

Among 190 wheat genotypes (CIMMYT), 51 lines were evaluated for adult plant resistance (APR) to stem rust infection at Sakha, Kafr El-Hamam and Nubaria locations, as the new sources of this resistance. Extensive and high significant differences of stem rust reaction among the tested wheat lines were obtained, at the three locations under study. Out of 51 wheat genotypes, only eight promising lines; no's 1, 9, 12, 14, 20, 25, 47 and 49 had the highest resistant potentiality at adult stage (completely resistant) and utilized as the new sources to increase stem rust resistance. Twenty nine wheat lines were characterized as partially resistant (PR), at the three locations of the study. The phenotypic variations were attributable to genetic structures of the lines due to high heritability estimates (up to 99%) and high values of genetic advance. The importance of all the selected disease parameters was confirmed through the correlation analysis especially final rust severity (FRS %). It is considered to be the more appropriate indicator, rather than area under disease progress curve (AUDPC) and relative area under disease progress curve (rAUDPC) for screening large numbers of breeding materials to stem rust resistance and facilitate the success of selection process, during a national breeding program.

Insect α-amylase has recently become a target of insect control strategies using plant-derived α-amylase inhibitors especially for the control of stored product insect pests. The first step to establish such strategy is to characterize the α-amylase enzymes in the target pest. In the current study, α-amylase was biochemically characterized in the larval and adult stages of <em>Tribolium castaneum</em> and <em>Callosobruchus maculatus.</em> <em>T. castaneum</em> was found to have higher α-amylase activity with lower temperature stability compared to that of <em>C. maculatus.</em> The optimum pH for α-amylase activity was 5-6. Zymogram pattern revealed the presence of two α-amylase isoforms with high molecule weight in <em>T. castaneum. C. maculatus </em>has two α-amylase isoforms in the adult stage and three isoforms in the larval stage. Rice α-amylase inhibitors was purified and found to have strong inhibitory effect against α-amylase of both insects and also negatively affected their life parameters.
