ENVIRONMENTAL FACTORS AFFECTING THE IMMATURE STAGES MORTALITY OF Bacrocera papayae
F.
Muttardy
Three major parasitoids of Bacrocera papyae (Drew) were recorded in papaya , Biosters vandenboschi, B. longicaudatus and B.arisanus.Relationships between total initial hosts ( B.papayae immatures ) and total hosts killed by each parasitoid species good correlation and parasitoids relationships were not density dependent. The percentage of the larvae that survived through fruit factors was 84.2% in soil, the soil factors reduced survival to 21.3%, amongst the soil, weather accounted for 45.5% biotic factors 16.5 and physical factors 2.5%.While predator ant ( Dolicholderus and Componotus sp. ) 19.1% of mortality.

The predatory efficiency of four aquatic predators [Bufo regularis L., Orthetrum spp., Anisops sardea Herrich Schaeffer and Sigara selecta (Fiebre)] at three constant temperatures (15, 25 and 35°C) was evaluated on culicine larvae. Results showed significant variation in predation rate between the four predators at the three constant temperatures tested. Regardless of temperature, the predator Orthetrum spp. exhibited the highest active predators (18.1 larvae/day), followed by A. sardea ((12.2 larvae/day). B. regularis and S. selecta showed significant low predation rate (5.7 and 1.0 larvae/day). The predatory efficacy of the four predators was higher at 25 and 35°C than that at 15°C.

The effects of profenofos on rat testis and liver was evaluated when applied for 10 weeks, either alone or mixed with vitamin C. Sperm counts, motility, morphology, reduced glutathione, catalase, superoxide dismutase, malodialdehyde, testosterone level, RT-PCR SSCP of gene P53 were studies. Significant decrease in sperm motility and survival were observed in treated rats. Serum testosterone decreased after exposure for 5 and 10 weeks. MDA content in serum, liver and testis showed significant increase. The activity of hepatic SOD increased, while CAT activity was not changed after 5 weeks exposure. After 10 weeks exposure, the activity of SOD and CAT in both liver and testis, were lower than the control group. At the end of the two exposure periods, GSH levels in both tissues were significantly higher in profenofos treated groups compared to control group. Results of 10 weeks exposure using RT- PCR SSCP analysis suggested profenofos induction of genotoxicity.

Two doses (5 and 10 gms) of 14 powders (hive products and plant materials) were added to mulberry leaves, and two levels (%) of 14 liquid treatments (hive products, honey, pollen, royal jelly and propolis and their mixtures) were sprayed on mulberry leaves which feed to 4th and 5th instar larvae of silkworm. Effects on haematological characters, Total Soluble Solids % (T.S.S.%), Total Haemocyte Counts/mm3 haemolymph (T.H.C.), and Differential Haemocytes Counts % (D.H.C.%), were studied in 5th instar larval haemolymph. The best tested powders (gm), and liquids (%), with respect to (T.S.S.%) can be arranged desindinglly as follow: Palm Pollen, hand-collected (10 gm), Pollen from honey bee colonies (10 gm). Drone brood, dried (5 gm), Soya flour, defatted (10 gm), Pollen (0.3%), Pollen (5 gm), Royal Jelly (0.03%), and Honey (1%). This depends on % increment of these treatments over control. Concerning (T.H.C.), the best treatments were: Palm Pollen (10 or 5 gms), Pollen (10 gm), Royal Jelly (0.02%), Pollen (0.2%), Pollen + Propolis (0.2% + 0.1%), and Drone Brood (5 or 10 gms). Powder treatment was more effective as compared with liquid treatment, with respect to T.S.S.% and T.H.C. Prohaemocytes %, was higher in Pollen (0.2 & 0.3%) and its mixture with Royal Jelly (0.2% + 0.02%), Plasmatocytes %, Granular cells %, and Oenocytoides %, were in Pollen + Honey (0.2% + 2%); Pollen + Propolis (0.2% + 0.1%) and Honey + Royal Jelly (2% + 0.02%), treatments, respectively, while Spindle cells % were more in control, as compared with all tested liquid treatments. In powder treatments (gm), maximum % abundance of prohaemocytes was in Pollen (5 & 10 gms), Soya (5 & 10 gm), Palm Pollen (5 & 10 gms) and Drone Brood (10 gms). Maximum % abundance of other haemocytes types, was noticed with powders from Vasaka, Buddleia, and Spearmint leaves. Statistical analysis of obtained data revealed highly significant differences between treatments and used doses, and these data were discussed.

TOXICITY OF SOME INSECT GROWTH REGULATORS (IGRs) AND THEIR BINARY MIXTURES WITH OILS ON COTTON LEAFWORM LARVAE SPODOPTERA LITTORALIS (BOISD)
S.
Hamed
Toxicity effects of tow insect growth regulators (IGRs) chlorfluazuron and flufenoxuron alone and their combinations with oils at quarter, half and recommended rates were studied by using second (2nd) and fourth 4th larval instars of the cotton leafworm, Spodoptera littoralis. (Boisduval). The results achieved in this study can be summarized in the following, chlorfluazuron was more toxic on both 2nd and 4th larval instars than flufenoxuron when used alone at quarter, half and recommended rates.
Concerning the effect of binary mixtures of the tested compounds at half-and quarter recommended dose, chlorfluazuron when mixed with Kz oil exhibited highly mortalities against 2 nd instar larvae of field strain of S. littoralis which caused 96.17% as residual effect compared with chlorfluazuron when used alone (91.45%) at half recommended dose. While, chlorfluazuron + Hopa oil was recorded high mortality 94.47% at quarter- recommended dose as residual effect compared with chlorfluazuron when used alone (81.23%) at the quarter recommended rate .Also, Flufenuxuron + Hopa oil has the highest residual activity (95,25%) when compared to 79.10% for flufenuxuron alone at the half recommended rate. While, flufenuxuron + Misrona oil was recorded high mortality 82.93% as residual effect compared with 73.01% for flufenuxuron when used alone at the quarter recommended rate .
Also, regarding the chlorfluazuron when mixed with Kz oil exhibited highly mortalities against 4 th instar larvae of field strain of S. littoralis which caused 95.40% as residual effect compared with chlorfluazuron when used alone (92.94%) at the half recommended rate. While, chlorfluazuron + Kz oil was recorded high mortality 92.62% as residual effect as compared with chlorfluazuron when used alone (80.48%) at the quarter recommended rate .The data also confirmed that, flufenuxuron + Hopa oil has the highest residual activity (93, 5%) when compared of 71.53% for flufenuxuron alone at the quarter recommended rate . While, flufenuxuron + Misrona oil was recorded high mortality 79.29% as residual effect compared with 70.96% for flufenuxuron when used alone at the quarter recommended rate .
It could be concluded that,the oils when mixed with IGRS enhanced the toxicity effect of IGRs against 2nd and 4 th instar larvae of field strain of S littoralis.

Topsin M70 (thiophanate-methyl 70%) is recommended in Egypt to control many plant diseases such as root rot, powdery mildew, and fruits rot on different crops such as strawberry, mango, panama, apple, and grape. Latterly it was found to be superior to control cucumber stem and fruit white mold. Fungicide residues have been found on food for human consumption, mostly from post-harvest treatments all over the world. Cucumber fruits have short shelf life time and most of cucumber production is eaten fresh, or in salad. It was important to assess the risks of long term consumption of cucumber fruits contaminated with thiophanate-methyl specially their possible effect on liver functions and blood picture. In this respect, two groups of rats were fed with two concentrations of cucumber contaminated with the fungicide and the data were compared with third group which was fed on clean diet. The tests showed higher level of each of Alanine Aminotransferase (ALT), Aspartate Aminotransferase (AST) Alkaline phosphates ((ALP) enzymes at both fungicide concentrations. Albumin content was decreased and in turn, total protein was decreased. On the contrary, increasing concentrations of cholesterol was recorded. As for red blood cell count (RBC), HCT and blood platelets they decreased. On the other hand white blood cells distractedly increased; the white blood cells increase side by side with the decreasing of the red blood cells invoke the suspicion that thiophanate methyl can badly affect bone marrow and/or has carcinogenic effect which may cause leukemia.

RESPONSE OF THE OLIVE FRUIT FLY, Bactrocera oleae ROSSI TO SOME AMMONIUM COMPOUNDS AND CERTAIN FOOD ATTRACTANTS UNDER FIELD CONDITIONS IN OLIVE ORCHARDS
M.
El-Metwally
The olive fruit fly, Bactrocera oleae Rossi is a serious pest attacking olive fruits causing a quantitive and qualitative damages. The response of olive fruit fly adults to some ammonium compounds and certain food attractants was evaluated under field conditions throughout two experimental trails. The study was carried out at olive orchards of Dakhlia governorate by using the modified Nadel traps during the period of July 2011 until January 2012. The obtained results illustrated that the olive fruit fly, B. oleae exhibited different responses to the tested compounds depending on the average temperature and used concentration. For the 1st trail, six local ammonium compounds including ammonium acetate, di-ammonium phosphate, ammonium chloride, ammonium carbonate, ammonium hydroxide and ammonium bicarbonate were evaluated as lures for B. oleae adult flies. Four concentrations (1,2,3 and 4%) of each compound were evaluated during months of July, September and October 2011.
Among all tested ammonium compounds, two concentrations of Ammonium acetate (3 & 4%) exhibited the highest efficiency and lured ,8.25 & 8.00 flies/ trap/14 days. In the second trial, certain food attractants were evaluated in comparison with diammonium phosphate and ammonium acetate ( at 1, 2, 3 and 4 %) during October, December 2011 and January 2012. The tested food attractants included Buminal, Prolure and Conserve (GF-120) at concentrations of 2.5, 5 and 10%. In addition Torula yeast was also evaluated at rates of 2, 3 and 4 pellets of Torula yeast /300 cm3 water. Diammonium phosphate 2, 3, 1% and Buminal 2.5% recorded the highest efficiency with 19.58, 18.58, 17.08 and 16.52 flies/trap/ 14 days, respectively. The obtained results indicate that di-ammonium phosphate and ammonium acetate could be involved in population monitoring and mass trapping technique of B. oleae as a part of its integrated control program due to their superiority in female attractancy of B. oleae and lower cost when compared with other food attractants.
