The effect of Metarhizium anisopliae var.acridum and four bioactive compounds (Neem,L- Glutamic acid,Schinusmolle and abamectin) in sole treatments and in combination with M. anisopliae var.acridum was studied on activity of Lactate Dehydrogenase Trehalase, Phenol oxidase, and Acid Phosphates in 5thnymphal instar haemolymph of desert locust. Obtained results showed that the integration of M. anisopliae var. acridumand the Four bioactive compounds caused 100 % mortality after six days post treatments, also caused severe reduction in activity of all studied enzymes. M anisopliae var.acridum treatment caused significant reduction in Lactate Dehydrogenase by the second day after treatment, but all treatments caused significant reduction in Lactate Dehydrogenase by 4th day post treatment except Neem. In case of trehalase all treatments were significantly lower than control treatment except abamectin two days post treatment, but by day four all treatments were lower than control, while in the 6th day post treatment S. molle, L- Glutamic acid and Neem treatments caused significant increase in Trehales activity. All treatments caused significant increase in Phenol oxidase activity two days post treatment except L- Glutamic acid and abamectin treatment, while after four days Neem and M.var.acridum treatment were still higher than control, but other treatments were significantly lower than control treatment, by the 6th day post treatment only L- Glutamic acid caused significant increase in Phenol oxidase activity. In the situation of Acid phosphatase activity two days post treatment abamectin , L- Glutamic acid and M. anisopliaevar.acridum + L- Glutamic acid were significantly lower than control, while after four days all treatments were significantly lower than control, after sex days post treatment only M.anisopliaevar.acridum and L- Glutamic acid were lower than control

A pot trial was carried out to verify the impact of four grounded seeds i.e. caster, garlic, maize and sesame separately added as pre or post planting applications to tomato plants under the stress of Meloidogyne incognita infection in comparison with oxamyl in the greenhouse. Noticeably, data indicated that all tested organic materials as grounded seeds improved plant growth criteria and reduced nematode parameters as well. Using sesame grounded seeds as pre or post applications showed the maximum values of plant length (82.4 and 70.8%),total plant fresh weight (104.0 and 80.2%),shoot dry weight(65.5 and 65.5%),respectively. In the meantime, sesame grounded seeds accomplished the highest reduction percentage in numbers of eggmasses and galls / root system in this study. Caster application ranked second in this respect, whereas plant receiving the maize grounded seeds as pre-planting application gave the lowest amount values in enhancing plant growth parameters. It is evident that N, P, K, OM and O.C concentrations were obviously reduced by nematode infection with various degrees. All tested components showed remarkable increase in N, P, K, OM and O.C concentrations exceeding those of nematode alone.

The vedalia predator Rodolia cardinalis considered as a main natural enemy for the biological control of mealy bugs, Icerya purchasi, I. aegyptiaca and I. seychellarum. Laboratory studies were conducted to determine the effect of cold storage on the developmental stages of R. cardinalis. Eggs of the predator were stored for 5, 10, 15 and 20 days at 6, 10 and 14 °C, , larval instars were stored for 5, 10, 20 and 30 days at 10 and 14 °C. R. cardinalis pupae were stored 5, 10, 20, 30 and 40 days at 6, 10 and 14 °C, while adults were stored for 5, 10, 20 and 30 days at 6 and 10 °C. Hatchability percentage of eggs decrease with the increase of storage period at 6°C, it averaged 84 ±10.2 (eggs one day old) and 78 ± 11.6 (eggs two days old) after 5 day of storage at 6°C, however at 6°C and 10°C eggs one and two days old, no egg hatching was observed after 25 days of storage. All eggs held for 25 days at 6°C and 10°C failed to hatch. The survival of third and fourth instar larvae stored at 6°C and 10°C was higher than the first and second instar. The fourth instar larvae of R. cardinalis were the most tolerable for cold storage. These results also provide novel findings that the fourth larval instar and eggs of R. cardinalis can be stored for twenty days at 10 °C, adult and pupae stored at 6 °C for twenty days with no reduction in viability for each stage. The results indicate that a cold storage of R. cardinalis could be used for maintaining and accumulating these predators during mass propagation for release in a biological control program and increasing the shelf-life of predators in clean agriculture.

The functional response of the three larval instars of predatory green lacewing, Chrysoperla carnea (Stephens) (Neuroptera: Chrysopidae), fed the two spotted spider mite, Tetranychus urticae Koch (Acari: Tetranychidae). First and second instars functional type II predator responses against T. urticae prey. Third instar showed type III functional response. The rate of the three larval instars of C. carnea attack was 0.0113, 0.061 and 0.057 respectively. Whereas handling time (Th) of the three larval stages of C. carnea was recorded 0.5639 and 0.048 respectively 0.021h., on the other side, the expected maximum consumption (T/ Th) of three larval instat of C. carnea is 42.8, 500 and 1142 per day for adult T. urticae respectively. The results of this study showed that larvae of C. carnea, mostly the final instars, have well possibility to benefit from predation spider mites.

The effect of Metarhizium acridum and four bioactive compounds (Neem, L- Glutamic acid, Schinus molle and abamectin) in sole treatments and in combination with M. acridum was studied on the mortality of 5th nymphal instar of desert locust Schistocerca gregaria as well as the time mortality responses and the ultra-structure of females ovary. The obtained results showed that mortality in case of Metarhizium acridum treatment reached to 100% after 14 days, while in case of neem treatment the mortality reached to 60 % after 12 days, at the same time the mortality reached up to 20 % after 10 days post treatment with L- Glutamic acid, but such mortality reached to 50 % after 14 days post treatment with Schinus molle extract, finally the mortality reached to 60 % after 11 days of abamectin treatment. All the mixtures with M. acridum caused 100 % mortality by the 5th day post treatment. However the sole treatments caused long time to kill 50 % of treated insects (LT50), where the LT50 of M. acridum was 7.261 day as the fastest treatment, while all mixtures caused accelerate in the mortality,but the best result was obtained in case of M. acridum + neem treatment which LT50 was only1.625 day.
Any way there were different effects on ultra-structure of the ovary as result of treatments used. Such effects varied between changes in nucleus shape to changes and destruction of nuclus it self.

The experiments of this study were conducted at lab, greenhouse and the experimental farm of Rice Research and Training Center (RRTC), Sakha, Kafr El-Sheikh during 2013, 2014 and 2015 seasons.. Results indicated that all the tested isolates of F. moniliforme (21) varied in their virulence. However, the high virulent isolates were obtained from isolates no, 12, 2 and 1 which gave 79.33, 73.33 and 72.0% ; infection respectively. While, isolate no. 6 was avirulent one. Also, results indicated that all rice cvs. differed in their susceptibility to infection with tesed isolates of F. moniliforme. Sakha 101 and Giza 177, were the most susceptible cvs. Hybrid 1 and Hybrid 2 exhibited the highest infection percentage. Survival percentage of Fusarium moniliforme in the infected grains or soil gradually after 2-10 months, then decreased tremendously after two years of storage either in a screenhouse or at room temperature. The results indicated that the highest number of dead(infected) plants were (17.67 plant/pot) was obtained from seedling infection 100% at 10 DAT compared with (0.5 plant/pot) of healthy 100 %. Moreover, the highest number of infected plant (14 plant/pot) was obtained from seedling infection 65 % followed by (12.00 plant/pot) from seedling infection 75 % at 45 DAT compared (0.70 plant/pot) of healthy 100 %. Data indicated that, the highest grain yield (4.962, 4.899 and 4.856 t/fed) was in treatment of spray at 5 DAF followed by spray at 15 DAF(4.826, 4.685 and 4.697 t/fed) that obtained from Beam, Sumi8 and Vitavax spray treatments, respectively compared with control (4.125 t/fed) at 2013 season.

Plants extracts and essential oils were used in pest management in different crops against various pests. Under field conditions, we examined the effect of two plant extracts and four essential aromatic oils on the response of tomato hybrid cultivar Gold Stone to Tuta absoluta infestation. Also, their effects on some growth characteristics of tomato plants as well as their total phenolic compounds and total flavonoids contents were explored in the two successive summer seasons of 2011 and 2012. The treatments were Lemon grass extract (Cymbopogon citratus) at 25 gm /L., Garlic extract (Allium sativum) at 5ml / L., Eucalyptus oil (Eucalyptus spp.) at 0.5%, Rue oil (Ruta graveolens) at 0.5%, Anise oil (Ocimum basilicum) at 0.5%, Basil oil (Pimpinella anisum) at 0.5%. Ethyl acetate (Solvent) and tap water (Control). The plants were sprayed three times at two week intervals starting after 40 days from transplanting. All treatments reduced population density of Tuta absoluta significantly. The highest reduction was recorded by garlic extract followed by lemon grass extract and basil oil. Lemon grass extract significantly increased L-ascorbic acid (Vitamin C) contents in tomato fruits followed by basil oil. Also, garlic extract increased the yield of tomato significantly followed by eucalyptus oil in the first season while in the second season, anise oil followed by garlic extract were insignificantly increased the fruit yield than the other tested treatments. On the other hand, garlic extract recorded the highest values of total phenolic compounds (TPCs) and total flavonoids (TFs) in unifested and infested – treated tomato leaves.
