Evaluation of the Efficiency of Certain Attractive Toxic Baits for the Control of the House Fly, Musca domestica (Diptera: Muscidac)

Abstract

The efficiency of boric acid, borax and imidacloprid is evaluated for inhibition of adult house fly emergence (IC values) as dry and liquid baits. In the two cases, imidacloprid has the greatest fatal effect at both IC50 and IC90 levels followed by boric acid and then borax. In the liquid formulation, IC50 and IC90 values are (0.083 and 2.6%), (0.19 and 2.48%) and (2.6 and 16.9%) for three tested compounds respectively. The relative efficiency for imidacloprid and boric acid compared to borax (the least potent one), imidacloprid and boric acid achieved 31.3 and 13.7 times more suppression of adult emergence than borax. In the solid formulation, IC50 and IC90 values are (0.083 - 0.67%) followed by boric acid (3.7-11.6%) and borax (5.74-21.1%) respectively. It’s clear that imidacloprid 68.8 times and boric acid 1.5 times as toxic as borax. Reasons for differences in manifestation of mortality and possibilities for practical application are discussed. We conclude that the efficiency of tested compounds as liquid baits is higher than it as dry baits.
