Abstract
Peanuts treated with 20.9. 36.4 or 52.2 ppm pirimiphos-methyl to assess effectiveness of the insecticide were held in open-top, 141.6-liter, cylindrical bins for 12 mo in a warehouse infested with 10 species of stored-product insects Peanuts treated at 52.2 ppm malathion were the standard. Pirimiphos-methyl was as effective or more effective than the standard in reducing the number of insects. Also, peanuts treated with pirimiphos-methyl had fewer insect-damaged kernels than those treated with malathion. Red flour beetles, Tribolium castaneum (Herbst), and almond moths, Cadra cautella (Walker), were the pre-dominant species found. Residues of pirimiphos-methyl decreased gradually at a rate ca. 33% less than malathion during the 12-mo period.This publication has 1 reference indexed in Scilit:
