Adult mortality and blood feeding behavioral effects of α-amyrin acetate, a novel bioactive compound on in vivo exposed females of Anopheles stephensi Liston (Diptera: Culicidae).

摘要: The effect of α-amyrin acetate on mortality and blood feeding behavior in females Anopheles stephensi was assessed by vivo exposure treated guinea pig skin. In to caused mosquito knock down the form rapidly normally reversible paralysis subsequent record at end a 24 h, revealed rates increased from 0.0% (Control) 76.9% 1.6% acetate, highest concentration which implies contact toxicity received through sensitive parts test species. mean probing time responses significantly (P < 0.05) 5.3 s 22.9 acetate. engorgement times were shorter when compared control. exposed decreased 91.7% (control) 41.5% 0.8% concentrations, also 278.6 158.7 concentrations. Mean statistically significant that fecundity levels reduced 96.2 65.95%. shortened smaller meal size have played more important role decline fecundity. time, rate declined reduce overall survival reproductive capacity malaria vector A. stephensi.
