Activity of Ro13-5223 and Ro13-7744 Against Stored-Product Insects1

Abstract
Two carbamate-type compounds that exhibit juvenile hormone activity were effective as progeny suppressants of stored-product insects. Ro13-5223 {ethyl [2-(p-phenoxyphenoxy)ethy1] carbamate} prevented development of F1 progeny of nine coleopteran and three lepidopteran species at < 0.1 to 10 ppm levels in wheat media. Ro13-7744 {S-ethyl [2-(p-phenoxyphenoxy)ethy1] thiocarbamate} was slightly less active against three of the species. A malathion-resistant strain of the Indian meal moth was not cross-resistant to Ro13-5223.
