Abstract：
:Bruchid beetles infest various seeds. The seed coat is the first protective barrier against bruchid infestation. Although non-host seed coats often impair the oviposition, eclosion and survival of the bruchid Callosobruchus maculatus larvae, morphological and biochemical aspects of this phenomenon remain unclear. Here we show that Phaseolus vulgaris (non-host) seed coat reduced C. maculatus female oviposition about 48%, increased 83% the seed penetration time, reduced larval mass and survival about 62 % and 40 % respectively. Interestingly, we found no visible effect on the major events of insect embryogenesis, namely the formation of the cellular blastoderm, germ band extension/retraction, embryo segmentation, appendage formation and dorsal closure. Larvae fed on P. vulgaris seed coat have greater FITC fluorescence signal in the midgut than in the feces, as opposed to what is observed in control larvae fed on Vigna unguiculata. Cysteine protease, α-amylase and α-glucosidase activities were reduced in larvae fed on P. vulgaris natural seed coat. Taken together, our results suggest that although P. vulgaris seed coat does not interfere with C. maculatus embryonic development, food digestion was clearly compromised, impacting larval fitness (e.g. body mass and survivability).
