Conteúdo: | The citrus leafminer, Phyllocnistis citrella Stainton, is native to Asia and was detected for the first time in Brasil in 1996. The objectives of this study were to conduct a survey of parasitoids attacking citrus leafminer in Jaguariuna, one of the citrus production regions of Sao Paulo State, Brazil, and to determine whether indigenous species were providing effective control of this pest species. The collections of new leaves were made weekly at citrus groves in Jaguariuna from October 1996 to October 1997. Of the six indigenous parasitoids which were found, Galeopsomyia fausta LaSalle was the most abundant parasitoid of P. citrella in this region, accounting for more than 90% of the specimens collected. Thus, this species is a serius candidate for Biological control of the citrus leafminer in this region of Brazil. Other species collected were Horismenus sp., Cirrospilus 'sp.,C`, Elasmus sp., Eupelmus sp. and Conura (Ceratosmicra) sp. The mean percentage of parasitism was 39.28% (6.19 - 86.21%) in unsprayed orchards and 21.38% (1.33 - 56.63%) in orchards that were occasionally treated with fungicides, acaricides and inseticides Temik and Dipterex.
