ABSTRACT: In this study, the biological effects of various concentrations of Melia azedarach, Rhazya stricta, Jatropha curcas, Artemisia herba alba, Calotropis procera, Matricharia chamomella and Diflubenzuron were assayed on an Aedes aegypti (L.) test population under controlled laboratory conditions. Concentration levels of responses were evaluated. Characteristics such as IC50 and IC90 the susceptibility of immature stages to these plant extracts and insect growth regulator and their accumulation effects were studied. The percentage mortality of the fourth instar of Ae. aegypti larvae increased significantly with latex concentrations, indicating a direct relationship between the concentration and different effects. The larval mortalities ranged between low or moderate. According the mode of action of different plant extracts and Diflubenzuron did not appear to give high percentage of mortality against larval stages, although in most cases a clearly delayed inhibition of adult emergence was noted. The survival pupae percentage that produced from treated with different concentrations indicated that increased significantly of pupal survival due to decreasing the concentrations. There were significantly larval mortality and inhibition adult emergency percent in the treated groups compared to the control group. The characteristics investigated here indicate that this plant extracts and insect growth regulators are effective alternatives for controlling the dengue vector.
