Susceptibility of (Say) Larvae to Methanolic Extracts of .

<b>Background and Objective:</b> Environment pollution and resistance of many pests to the most frequently used chemical insecticides gave the rationale of altering to replace them with natural herbal extracts for pests and vector control. This study investigated the effect of methanolic extract of <i>Annona reticulata</i> on the mortality and development of larvae of <i>Culex quinquefasciatus</i>. <b>Materials and Methods:</b> Methanolic herbal extracts were analyzed using Reverse-Phase High-Performance Liquid Chromatography (RP-HPLC) to identify the phytochemical compounds in them.

Evidence Based Efficacy of Selected Herbal Extracts Against (Say) Larvae.

Background And Objective: Chemical insecticides have some limitations in vectors control such as the emergence of resistance in vector mosquitoes to conventional synthetic insecticides. It aimed to evaluate the larvicidal efficacy and phytochemical potential of Azadirachta indica, Cymbopogon citratus and Allium sativum L. against ulex quinquefasciatus fourth instar larvae.
