Field studies were conducted to assess the effectiveness of the parasitoid wasps, Cephalonomia waterstoni (Gahan), and Choetospila elegans (Westwood), for controlling Cryptolestes ferrugineus (Stephens), rusty grain beetle and Rhyzopertha dominica (F

Cross-resistance spectra of colonies of Plodia interpunctella (Hubner) resistant to strains of Bacillus thuringiensis Berliner subspp. kurstaki, aizawai , and entomocidus reflected the toxin composition of the B. thuringiensis isolates used for selec

Processing of Bacillus thuringiensis protoxins to toxins by midgut proteinases from a strain of the Indianmeal moth, Plodia interpunctella (Hubner), resistant to B. thuringiensis subspecies entomocidus (HD-198) was slower than that by midgut proteina

Insect resistance is now recognized as a serious threat to the long‐term usefulness of Bacillus thuringiensis (Bt) toxins in pest management. Because of the great diversity among Bt toxins found in nature, one of the most tempting resistance manage

The attraction of adult Rhyzopertha dominica (F.) to its aggregation pheromone and to volatiles of infested wheat was examined in relation to age, sex, and female mating status. Male and female beetles did not differ in their response to pheromone or
