Abstract Sexual selection is predicted to influence population persistence because skew in male reproductive success may facilitate the purging of mutation load. We manipulated strength sexual populations Indian meal moths, Plodia interpunctella, by adjusting adult sex ratios be either male- or female-biased, leading strong and weak males, respectively. After between 19 22 generations experimen...

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...
