Evaluation of Penicillium mycotoxins for activity in stored-product Coleoptera
Environmental Entomology 9 (2), 217-221
Abstract: The mycotoxins ochratoxin A, citrinin, rubratoxin B, patulin, penicillic acid and oxalic acid were fed to Tribolium confusum, Lasioderma serricorne and Attagenus megatoma in whole wheat flour. Penicillic and oxalic acids were not toxic to these insects at any concentration tested. Ochratoxin A and citrinin inhibited larval growth of A. megatoma at 10 and 1000 ppm, respectively, but rubratoxin B had no effect. Citrinin and rubratoxin B inhibited larval growth of T. confusum and L. serricorne at 1000 ppm only. Patulin inhibited growth of T. confusum at 1000 ppm both with and without yeast supplementation of the diet. L. serricorne larval growth slowed when patulin (at all concentrations) but no yeast was in the diet. Larval development time was increased whenever larval growth rates were inhibited. Reproduction of T. confusum was decreased by citrinin, patulin and ochratoxin A. L. serricorne reproduction was affected only by citrinin.
