Preliminary evaluation of new candidate materials as toxicants, repellents, and attractants against stored-product insects

TLDR: Two compounds, Bay 88991 and Penick SBP1382, showed promise as repellents against confused flour beetles and generally less toxic to the insects than was the malathion standard.

Abstract: Preliminaly evaluation of new promising chemicals for toxicity and repellancy were conducted at the Stored-Product Insects Research and Development Laboratory, Savannah, Ga. Six compounds were tested against adult confused flour beetles, Tribolium confusum Jacqulin duVal, and black carpet beetle larvae, Attagenus megatoma (F.). Of the six compounds tested four showed promise as direct-contact toxicants against both species. These four were Bay 75546 (ENT-27607), Bay 79845 (ENT-27608), Bay 88991 (ENT-27626), and Penick SBP1382 (ENT-27474). All of the compounds, except Bay 88991, when tested as residuals, were generally less toxic to the insects than was the malathion standard. Two compounds, Bay 88991 and Penick SBP1382, showed promise as repellents against confused flour beetles.
