Two experimental insecticides, TH-6041 [N, 3-bis(4-chlorophenyl)-4,5-dihydro-1 H-pyrazole-I-carboxamide] and TH-6042 [N, 3-bis(4-chlorophenyl)-4,5-phenyl-1 H-pyrazole-1-carboxamide] were relatively toxic on wheat to the adult stages of the rice weevil, Sitophilus oryzae (L.), granary weevil. S. granarius (L.), and lesser grain borer, Rhyzopertha dominica (F.) (LD95 ≤ 6 ppm). The confused flour beetle, Tribolium confusum Jacquelin duVal, sawtoothed grain beetle, Oryzaephilus surinamensis (L.), Indian meal moth, Plodia interpunctella (Hübner), Angoumois grain moth, Sitotroga cerealella (Olivier), and almond moth, Ephestia cautella (Walker), were more tolerant (LD95 ≥ 35 ppm). TH-6042 was very effective as a progeny suppressant against all Coleoptera (ID95 < 5 ppm) but only marginally active against Lepidoptera (ID95 < 48 ppm). TH-6041 had good activity against progeny of the rice weevil, granary weevil, sawtoothed grain beetle, and lesser grain borer (ID95 ≤ 26 ppm).
