ABSTRACT
In the present study, Lucilia cuprina maggots were used for the treatment of diabetic foot wounds. An artificial wound was made in diabetic foot of rabbit. The maggots were sterilized arid put directly on the wound after dressing the wound without using any antibiotics. Several cycles of maggots were put on the wound. The present results showed that the treatment of the diabetic foot was observed after 13 days. After this period the wound was completely healed and become free of microbial contamination. The new tissues were observed to close the wound

Ethanolic, acetone and petroleum ether extracts from leaves and stems of Lagenaria siceraria [Cucurbitaceae] were screened for their repellency effect against Culex pipiens L. mosquito. The repellent action of the present plant extracts were varied depending on the plant parts and the dose of extract. The petroleum ether extract of leaves showed the same repellency percent [100%] of commercial formulation, N. N.'diethyl toulamide [DEBT] at the higher dose [3.33 mg/cm[2]], while petroleum ether extract from stems exhibiting the repellent action [89.6%] at the same dose, respectively. Ethanolic extracts of leaves and stems exhibited the lowest repellent activity as it recorded [81.3% and 69.1%] at [6.67 mg/cm[2]], respectively. Results of this study may contribute to design an alternative way to control mosquitoes currently based on applications of synthetic insecticides. These extracts could be developed commercially as an effective personal protection measure against mosquito bites and thus to control diseases caused by mosquito-borne pathogens

Insect Repellents/adverse effectsABSTRACT
Laboratory investigations were carried out to asses the effect of some proteases inhibitors on the reproductive potential of Culex pipiens females resulted from larvae treated with different protease inhibitors. The fecundity and engorgement of symbiotic and aposymbiotic C. pipiens females were significantly reduced. The blood meal digestion period increased significantly. On the other hand, enzyme band with molecular weight of 40 KDa which may be cysteine protease was detected in untreated symbiotic and aposymbiotic female midguts. The results may explain that the absence of this enzyme bands in treated female midguts may be due to the inhibition caused by [E-64] a cysteine protease inhibitor

Laboratory investigations were carried out to study the effect of two protease inhibitors on the transmission of W. bancrofti filarial by Culex pipiens and to study the susceptibility interaction between filaria and protease inhibitors. The results obtained revealed that, infection rates were variable among untreated and treated symbiotic and aposymbiotic Cx. pipiens females resulted from third instar larvae treated with E-64 and EDTA. The survival rate was variable among untreated and treated symbiotic and aposymbiotic females resulted from third instar larvae treated with E-64 and EDTA. Protease inhibitor [E-64] caused inhibition of the parasite development and transmission by means of ceasing catalytic activity- responsible for parasite migration-caused by parasitic larval stages inside the mosquito vector
