Abstract

The developmental time and size of a solitary koinobiont parasitoid, Gronotoma micromorpha (Perkins) (Hymenoptera: Eucoilidae), were measured in two host species: the serpentine leafminer, Liriomyza trifolii (Burgess) (Diptera: Agromyzidae) and tomato leafminer, L. bryoniae (Kaltenbach). There was no significant difference in the developmental time of G. micromorpha in these two hosts. However, significantly larger G. micromorpha adults emerged from L. bryoniae than from L. trifolii puparia. Dissection of larvae revealed that when offered a choice G. micromorpha accepted larvae of L. bryoniae more often than those of L. trifolii. The number of wasps emerging from parasitized hosts did not differ significantly between host species. These results indicate that L. trifolii and L. bryoniae are both acceptable and suitable hosts for G. micromorpha. Gronotoma micromorpha may be a useful biological control agent of both L. trifolii and L. bryoniae.
