Ditliculty in controlling Melanotus communis Gyllenhal with aldrin prompted an investigation into factors affecting' control.

The following insecticides were evaluated in the laboratory for wireworm control: aldrin, diazinon, parathion, phorate. carbofuran, carbaryl, aldicarb, Supracide® (0,0- dimethyl phosphorodithioate S-ester with 4- (mecaptomethyl) -2-methoxy-2-1,3.4-thiadiazolin-5-onc), and Dyfonate®(O-ethyl S-phenyl ethylphosphonodithioate). Insecticides were applied to Bladen silt loam soil (9.0% organic matter content), organic loam soil (7.4% organic matter), and loamy fine sand (3.5% organic matter). Native wireworms from each of the 3 soil types were employed, and a loamy sand (1.3% organic matter) serve(1 as a low-organic-matter check soil.

Wireworm control with aldrin and diazinon decreased with an increase in the organic matter in the soil, whereas control with phorate was not affected by organic matter, and Dyfonate and parathion were only moderately affected. This investigation revealed that poor control of M. communis with aldrin was due to organic matter content of the soil and not to acquired resistance.
