Abstract

The debris-feeding insects Trogoderma glabrum (Hbst.), Tribolium madens Charp., Cryptolestes ferrugineus (Steph.), and Vitula edmandsae Pack, were controlled by cleaning out die nests of Megachile rotundata L. annually and screening off the debris, and by discarding the cells of M. rotundata after emergence was complete. The chalcidoid parasites Monodontomerus obscurus Westw. and Pteromalus venustus Wlkr. and the depredators Coelioxys spp., were removed by light-trapping them in the incubators in which M. rotundata was being hatched. The removal was made possible because the incubation period of each of the indigenous enemies was considerably shorter than that of their exotic host.
