Is Indian meal moth good at playing “oviposition-darts” when searching for holes in fruit bar packages?


Abstract: This work evaluated the effect of package perforations or micro- injury on the consequent infestation of cereal-fruit bars by the eggs of Indian meal moth, Plodia interpunctella. It was measured the “targeting” of oviposition by individual moth females on the unpackaged bars, bars in perforated packages, bars in undamaged packages and empty packages in laboratory experiments. Almost 100% of the laid eggs were laid directly on the bars when they were placed in the enclosure without packaging while few of the eggs were laid on either the empty or non-perforated polypropylene foil packages.
