Abstract

Sets of two types of sticky traps, horizontal wires and vertical panel traps, the latter including clear polyester, 1/2″ hardware cloth, and 1/4″ hardware cloth substrates, were run concurrently for eighteen weeks in a Missouri soybean field to see which gave the best taxonomic- and mass-frequency representations of the aeronaut fauna. The wire traps significantly underrepresented the largest family (Linyphiidae) and mass class (≤ 0.6 mg) in the fauna. Of the three panel trap substrates, there were no differences between the two hardware cloth meshes but the polyester trap catches declined significantly during cold periods in late fall. An estimate is given of the number of hardware cloth traps needed for an effective sampling program.
