Two cDNA fragments encoding full-length trypsinogen-like proteins were cloned from larvae of two strains (RC688s and HD198r) of the Indianmeal moth, Plodia interpunctella (Hübner), which differed in their sensitivity to Bacillus thuringiensis protoxins. One cDNA fragment contained 874 nucleotides, including a 780-nucleotide open reading frame that encoded a trypsinogen-like protein (PiT2b). Ano...

Wandering-phase ®fth instar Plodia interpuntella (HuÈ bner) were exposed at 3-week intervals for 0.5, 1, 2, and 4 h on concrete treated with sprays of 100, 150, and 200 mg 20% cy ̄uthrin wettable powder (WP) per m over a 15-week period. Pupation rate and adult emergence were not signi®cantly di€erent (Pr0.05) with respect to exposure interval at any application rate. Of the larvae exposed at wee...
