الملخص
Cost of pests control and environmental hazards had been one ofthe major problems constraining the use of chemical insecticides. Thiswork is aimed to evaluate the effect of Azadirachta indica (Neem),Balanites aegyptiaca (Lalob), Calatropis procera (Usher), Ocimumbasilicum (Rehan) and Solenotsemma argel (Hargel) water extracts testedagainst Culex quinquefasciatus 3rd instar larvae, which, if confirmedwould be used as natural pesticides. That would be economical, easy forapplication, locally available and non hazardous.The insecticidal effect of the above five plants water extracts wasfound to be very toxic against 3rd instar larvae of Culex quinquefasciatus.Analysis of variance (ANOVA) test was used to compare betweenthe different dose rates, different times and different five plants waterextracts. Statistical analysis suggested that insecticidal effect of B.aegyptiaca (Lalob) fruits kernel water extract was very high andsignificant after 24 hours. 100% mortality among larvae was obtainedafter 72 hours . The insecticidal effect of A. indica (Neem) seed waterextract was less high and significant than that of B. aegyptiaca (Lalob)fruits kernel. The insecticidal effect of O. basilicum (Rehan) waterextract came third after B. aegyptiaca. On the other hand the insecticidaleffect of C. procera (Usher) leaves water extract was less than O.basilicum (Rehan). S. argel (Hargel) leaves water extract was the leasteffective one . Mixing sesame oil with the five plants water extractsaffect significantly increased the larval mortality of Cx. quinquefasciatuscompared with the five plants water extracts alone after 24 hours.However, there was less mortality and not significant toxic effect ofthe five plants water extracts when applied against the mosquito naturalenemies, namely Bufo regularis, Dragon fly larvae, O. niloticusXIVfingerlings .The results obtained were not significantly different from thecontrol. Hence, the Natural animals found in the same environment arenot affected by these plants extracts.
