SUMMARY:

The leafminer Liriomyza sativae Blanchard is an economically important pest of vegetable crops worldwide. In Brazil, this agromyzid has caused significant damage to melon crops Cucumis melo L. in the semiarid region of the country. Based on this, studies on the diversity of parasitoids associated with L. sativae were carried out to verify their potential in biological control programs, and thus, implement effective control strategies for this pest. The endoparasitoids Chrysocharis caribea Boucek, Neochrysocharis formosa (Westwood), Phaedrotoma scabriventris Nixon and Zaeucoila unicarinata Ashmead parasitize the laval stages of the leafminer L. sativae, occur naturally in the Brazilian semiarid region and share the same ecological niche. Basic studies carried out in the laboratory are essential to understand primarily how the parasitoid-host relationship occurs between species. However, there are gaps that have not been fully clarified, mainly regarding the study of immature endoparasitoids associated with L. sativae. Therefore, this study aimed to: (i) Know the development time and morphologically describe the immature stages of C. caribea; (ii) estimate the encapsulation index of C. caribea, N. formosa, P. scabriventris and Z. unicarinata by the host L. sativae; and (iii) verify whether C. caribea and P. scabriventris compete or coexist, in order to explore the possible combined biological control of these species in future Integrated Management programs of the inadora fly in melon plants. In Brazil, these are the first studies with these species in this sense, and this knowledge makes it possible to understand how the interactions work, from basic to applied applications.
