COMPARATIVE COST CONTROL OF Atta sexdens rubropilosa FOREL 1908 USING COMMERCIAL GRAIN BAITS AND AN EXPERIMENTAL BAIT
Abstract
An Experiment was conducted using a clorimated experimental bait called EAV-041-A. This experiment was conducted to determine the efficiency of EAV-041-A using the leaf-cutting ant Atta sexdens rubropilosa as the test. The experiment was executed in Goiânia, Goiás, comparing it with the commercial baits: Mirex, Isca Shell and Agroceres AG-005. Results obtained showed Mirex was superior giving 93.30% control of the nests, EAV-041-A 80.00% and Isca Shell and Agroceres both qave 73.30% control. Total cost of application was calculated based on price of the bait on the market hand labor in the region, and efficiency of the various baits. Cost calculated on the basis of ant nests killed were in the following order: EAV-041-A Cr$ 2.21; Isca Shell Cr$ 3.41; Agroceres Cr$ 4.29 and Mirex Cr$ 5.44 (At the time of these calculations the official exchange rate was Cr$ 6.00 to US$ 1.00). This evidence proved EAV-041-A to be the most economical.
