Abstract: Survey of hymenoptera parasitoids of pink-hibiscus-mealybug, Maconellicoccus hirsutus (Green, 1908) infesting Hibiscus rosa-sinensis was conducted in two municipalities of state of São Paulo, Brazil from August 2016 to August 2017. Nine species of chalcidoid wasps were obtained- Anagyrus kamali Moursi (1948); Anagyrus sp. aff. mirtesae Noyes and Menezes (2000); Anagyrus sp.; Bothriocraera bicolor Compere and Zinna (1955); Cheiloneurus sp., Gyranusoidea deionae Noyes (2000); Prochiloneurus sp. (Encyrtidae); Aprostocetus sp. (Eulophidae); and Chartocerus sp. (Signiphoridae). Anagyrus kamali and G. deionae were the most frequent species, corresponding to 67.26% and 22.62% of the parasitoids, respectively. Bothriocraera bicolor, Chartocerus and G. deionae are recorded for the first time associated with M. hirsutus. Gyranusoidea deionae and B. bicolor are recorded for the first time in Brazil. The seasonal study of M. hirsutus and its parasitoids was carried out in January to December 2017on 16 hibiscus plants, aligned in the hedge in the experimental area of the FCAV/UNESP in Jaboticabal, SP. For this purpose, ovisacs, nymphs and adults of mealybug were counting on infested plants and the adult parasitoids collected in Möerick traps. Maconellicoccus hirsutus was observed during the periods of January-March and October-December, with the highest infestation in January and February. In the traps, a total of 92 specimens of pink-mealybug parasitoids were obtained- 65% belonging to A. kamali and 35% to G. deionae.
