YP4, a subunit of the follicular epithelium yolk protein in the moth, Plodia interpunctella, is produced in the follicle cells during vitellogenesis and after secretion is taken up into the oocyte and stored in the yolk spheres for utilization during embryogenesis. In order to identify the cDNA clones for YP4, a degenerate PCR primer was designed to six amino acid residues identified in the NH2...

ABSTRACT Low oxygen or hermetic storage has been successfully used to store several commodities such as corn (Zea mays L.), cowpea (Vigna Savi), cocoa (Theobroma cocao), coffee (Coffea and rice (Oryza sativa L.). However, previous research using for peanut groundnut (Arachis hypogaea L.) had mixed results. Research was conducted determine the effect on aflatoxin contamination, seed germination,...

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...
