Evaluation of the Efficiency of some Methods in Biological Control of Phlebotomus Papatasi (Diptera:Psychoididae).

Abstract

The research studies the biological efficiency of the fungus Verticillium lacanii and the alcoholic extract leaves Nerium sp Capparis sp. and Lawsonia sp. against fourth larval instar and adults of male and female Phlebotomus papatasi . The study was conducted at the laboratory condition at a temperature of 25±2°C, relative humidity. 65 ± 5% and a period of illumination of 12 hours/day. The suspension of Verticillium lacanii at a concentration of 1 × 10 8 spores/ml gave the highest mortality 86.74% for the fourth larval instar after 24 hours of treatment, while the suspension of Verticillium lacanii at concentration of 1 × 10 8 spores/ml gave the highest mortality of 78.16% for the male Phlebotomus papatasi after after 24 hours of treatment, the suspension of Verticillium lacanii at a concentration of 1 × 10 8 spores/ml gave the highest mortality rate of 46.75% for female after 24 treatment. Alcoholic extract of Capparis gave highest mortality 89.57% for the fourth larval instar, 76.18% for males, and 87.71% for the female Phlebotomus papatasi after 24 hours at concentration 0.07 mg/l. The alcoholic extract of Lawsonia sp. showed the lowest mortality was 43.01
