Abstract
Wild and cultivated plants were surveyed in Florida, the Caribbean, and Lat in America for parasitoids of Bemisia spp. whiteflies. Foliage samples cont aining late instar Bemisia nymphs were collected and held in the laboratory for emergence of adult parasitoids. Florida collections were made weekly, biweekly or monthly depending upon the time of year and location. Samples a lso were collected on an irregular basis in Caribbean and Latin American co untries including Brazil, Colombia, Costa Rica, Dominican Republic, Ecuador , Fl Salvador, Grenada, Guadeloupe, Guatemala, Honduras, Jamaica, Mexico, P uerto Rico and Venezuela. At least 20 species of parasitoids and one specie s of hyperparasitoid were reared from Bemisia. Encarsia pergandiella Howard (which may be a complex of species including the sympatric species E. taba civora Viggiani), E. nigricephala Dozier and Eretmocerus sop. were the most abundant parasitoids, accounting for 59%, 16% and 13%, respectively, of th e total reared from Bemisia. Encarsia meritoria Gahan, which is a complex o f species but which may be mostly E. hispida De Santis in the New World, wa s rarely collected in Florida but was abundant at some sites in the Caribbe an and Latin America.
