This study was carried out to study effect of treated cucumber plants var. Cucumis sativus L. by different concentrations of Triacontanol Hormone (TRIA) on the infestation by Aphis gossypii Glover at two locations (governorates), Giza overnorate and Qaluobiya Governorate during 2018 season under glasshouse conditions. Also, this study was carried out to study effect of treated cucumber plants by the same concentrations of (TRIA) hormone on the morphological characteristics and internal components of treated cucumber plants. This study was carried out on three concentrations of Triacontanol Hormone, (25ppm), (35ppm) and (55ppm), beside fourth treatment which did not treat with any hormone (control). Results obtained showed that cucumber plants which treated with small concentration of (TRIA) (25ppm) were lower infestation by A. gossypii comparing to control. While cucumber plants which treated with medium concentration of (TRIA) (35ppm) were had no significant differences in the infestation by the same insect compared to control, on the other hand cucumber plants which treated by high concentration of (TRIA) (55ppm) were higher infestation by the aphid compared to control.

Salem
Pigments are anti-oxidants, which play an important role in protecting against many diseases. In this study, pigments of different bee pollen types (Sunflowers, Clover, Sesame and Maize) were determined with ethanol solvent and stored under freeze condition. Sunflower bee pollen had the highest amounts of the studied 23 pigments except three pigments. Maize bee pollens were superior to sunflower bee pollen in its content of the three exception pigments (Isozeaxanthin, Zeaxanthin and B- Zeaxanthin). In Sunflower bee pollen there were no significant differences between fresh bee pollen and those stored for 6 months in most of pigments as compared with 12 months storage. Sunflower bee pollen either fresh or stored for 6 months produced the highest values of Isozeaxanthin, Lutein, Lycopene, Violaxanthin, Zeaxanthin, 8- APO- B- Carten- 8- al, α – Carotene, ß – Carotene and γ – Carotene compared to 12 months storage. However pigments of clover or sesame bee pollen were the lowest compared to sunflower and maize.

The present work was conducted during 2017 and 2018 seasons in Diarb-Nigm district at Sharhia Governorate, Egypt to study the effect of four rates of potassium fertilization (0, 24 , 48 , 72 Kg. K2o / fed.) on maize infestation with certain piercing-sucking insects such as aphids, Rhopalosiphum maidis and R. padi, leafhoppers and planthoppers , Empoasca decipiens, E.decedens, Balclutha hortensis, Cicadulina chinai, C. bipunctella , Sogatella vibix and S. furicefera and relationship with the chemical components and epidermal cells thickness of maize plant leaves. The results showed significant differences in the population density of the aforementioned insects of the tested rates of potassium fertilization, whereas, the highest mean numbers of their insects were recorded at the rate of F1(zero Kg. K2o /fed.), while the least mean numbers of the aforementioned insects occurred at the rate of F4(72 Kg. K2o / fed.). In addition, the results of some chemical analyses revealed that a positive relationship between total protein, carbohydrates contents, k values and the epidermal cell thickness and aforementioned rates of potassium fertilization. While, a reverse relationship was recorded between pH values and potassium fertilization. Also, the fertilization influenced significantly on six amino acids; aspartic, glutamic , glycine , alanine , isoleucine and leucine, which affected the attractive of these insect species, which may explain the decreasing in numbers of the insects by increasing the rates of fertilization. According to these results, the potassium fertilization should be recommended as effective factor in the integrated pests control program.

The pod borer Etiella zinckenella (Treitschke) is most destructive insect which infest crops of leguminosae in Egypt. Field experiments were carried out in farm of Agricultural Research Center, Giza governorate during 2017 and 2018 seasons. First experiment was conducted to study seasonal incidence of this insect on soybean and its relation with weather factors under natural conditions. In first season, the larval population increased to make two peaks, that recorded in the 1st and 3rd weeks of September. In second season found one peak on September, 4th. The relationship between population fluctuation and three climatic factors (minimum and maximum temperatures& R.H. %) were studied. Simple correlation of Max. and Min. temperatures were negative but R.H.% gave positive effects. The second experiment was conducted to evaluate efficacy of Biover, MgChl and Dipel 2xfor control of this insect under field conditions in addition the yield. Results showed that, mean reduction of larvae for highest concentrations of tested treatments were arranged descendingly as Biover (63.04%) followed by MgChl (55.52%) and finally Dipel 2x (51.28%) with significant differences between treatments compared with control. Also, depending on highest concentration, Biover was the superior in this respect being registered 45.71% increasing in the yield over the control value followed by MgChl (42.39 %) and Dipel 2x (36.19%). Maximum net return was obtained from Biover (4g/L) (4262.92 /fed.) followed by Biover (2g/L) (4172.92/fed.) and Diple 2x (4g/L) (3749.59/fed.). Biover and MgChl gave highest reduction in population of this insect and best seed yield.

The experiments were carried out at private farm belonging to Mansoura region. Four host plants from different vegetable families were chosen as eggplant (Solanaceae), squash (Cucurbitaceae), okra (Molvaceae) and cowpea. (Leguminosae). The population density of the cotton mealybug, Phenacoccus solenopsis (Tinsley) (Hemiptera: Pseudococcidae)recorded the highest peaks of abundance on okra plants during the two successive seasons 2018 and 2019 and presented by 341 and 397individuals in the third week of October 2018 and in the second week of October 2019, respectively. Moreover, on squash plants the highest peaks were recorded in the third week of October 2018 and in the second week of October 2019 and represented by 209 and 263, individuals respectively. Meanwhile, on eggplant, the highest peaks were recorded in the second week of October 2018 and in the third week of October 2019 and represented by 134 and 207 individuals, respectively. While, the population of the insect pest showed the highest peaks on cowpea plants in the fourth week of October in the two seasons and represented by 119 and 142 individuals, respectively. The highest average numbers of the insect pest on different vegetable crops were recorded in October for all tested host plants during the two successive seasons 2018 and 2019. Okra as vegetable host plant recorded the highest average number followed by squash, eggplant and cowpea with significantly differences during the two seasons. Also, okra attracted the highest total numbers of the insect during the two seasons.

Effect of acetone extracts of grape branches, grape leaves, moringa and mulberry leaves on chitin deposition in mulberry silkworm larvae were studied. As well as the effect of those extracts on the characteristics of cocoons and silk threads were studied. Two concentrations were used (20 and 40%) of the extracts and sprayed on the mulberry leaves offered to larvae at the second day of fifth larval instar. Moringa leaves extract caused the most significant reduction in chitin deposition, especially after 120 h. While grape leaves extract gave increase in chitin deposition at all times in both tested concentration. In addition, the grape sticks extract gave the same effect in concentration 20% but, chitin reduction noticed in concentration 40% after 120 h. The results indicated that applying acetone extract of grape branches and moringa leaves at 20 % and grape leaf extract at 40 % to mulberry leaves recorded the highest fresh cocoon weight and cocoon shell weight. Grape leaves extract at 20 % and grape branches extract at 40 % increased the silk ratio. The highest length of silk threads obtained from silkworm larvae fed mulberry leaves treated with grape branches at 20 and 40 %. The acetone extracts of grape leaves, grape branches and mulberry leaves at concentration 20 % increased the silk filament weight and size. Conclusion: using acetone extracts of grape leaves and branches and moringa leaves in terms of juvenoids is a potent tool for improving silkworm performance and cocoon characters, which resulted in the production of high raw silk yield.

Chemical constituents of Raphanus sativus Linn. roots were extracted and tested for their toxicity against adults and second instar nymphs of A. gossypii under laboratory conditions. The most effective fraction against both adults and nymphs was methylene chloride fraction with LC50 values of 386.63 and 309.43 ppm, followed by ethyl acetate fraction with LC50 values of 394.9 and 334.37 ppm then petroleum ether fraction with LC50 values of 636.2 and 424.56 ppm, for adults and nymphs, respectively. Also, the volatile components of each fraction were qualitatively and quantitatively identified and characterized by GC/MS technique. Moreover, the impact of the sub-lethal concentrations of R. sativus roots extracts on transaminases and alkaline phosphatase of A. gossypii was studied. Great inhibition of all tested enzymes activity was observed. This suggested the high potency of R. sativus roots extracts as environmentally friendly alternatives of traditional insecticides.
