Abstract

This study evaluated the ability of pteromalid parasitoids Anisopteromalus calandrae and Lariophagus distinguendus reared on Sitophilus zeamais to control stored product coleopteran pests Sitophilus oryzae, Rhyzopertha dominica and Lasioderma serricorne. In trials of parasitoid treatment with A. calandrae, fewer pests (S. oryzae and R. dominica) emerged than in the control. Parasitoid reproduction was highest with S. oryzae as a host, followed by R. dominica and L. serricorne. In trials of parasitoid treatment with L. distinguendus, fewer pests (S. oryzae, R. dominica and L. serricorne) emerged than in the control treatment. Sitophilus oryzae was the host with the highest rate of parasitoid reproduction, although the greatest level of reduction was seen in R. dominica (i.e., host feeding levels were higher for this host species). For L. serricorne, no L. distinguendus progeny was produced. For both species, parasitoids with significantly longer bodies and tibiae emerged from S. oryzae. These results suggest that both parasitoids have potential for use as biocontrol agents for different coleopteran species that attack stored rice.

Keywords: biological control; fecundity; host suitability; rice; stored products.
