Biological control of different larval ages of Culex pipiens mosquitoes using Bacillus thuringiensis isrealeansis and growth regulator Dimilin.

Abstract

This study was conducted in the Animal Research Laboratory / Animal House / College of Science / Al-Mustansiriya University to evaluate the efficiency of the growth regulator Dimilin, which inhibits the manufacture of chitin at three different concentrations 0.5, 1.0 and 1.5 ppm and the efficiency of the bacterial suspension Bacillus thuringiensis israelensis at concentrations 6.25×109, 6.25×1010 and 6.25×1011 spore/ml on different larval ages of Culex pipiens mosquitoes.
