摘要: The potential of Liriomyza commelinae (Frost) (Diptera: Agromyzidae) as an alternative host for parasitoids the pest leafminer huidobrensis (Blanchard) was investigated. We particularly focussed on specific composition parasitoid complex and its impact L. commelinae, frequency associations, dependency parasitism density additive effects species richness total parasitism. Mined leaves Commelina erecta (Commelinaceae) were collected from different localities Cordoba province (Argentina) 1991 to 1994, also sites city. In total, 25 (Hymenoptera) associated with which 13 shared huidobrensis. Chrysocharis flacilla Diglyphus websteri (Eulophidae) most abundant former being frequently leafminer. Total parasitism, averaging 50%, did not depend richness. No signif...
