The parasitism rate of Diglyphus isaea (Hymenoptera: Eulophidae) on Liriomyza sativae Blanchard (Diptera: Agromyzidae) in Mugla province

Liriomyza sativae blanchard (diptera: agromyzidae) blanchard is an important pests on bean in turkey. diglyphus isaea (walker) (hymenoptera: eulophidae) is one of the most common parasitoid of l. sativae. the aim of this study was to determine the natural parasitism rate of d. isaea on l. sativae. this study was carried out during autumn seasons of 2006 and 2007 in six bean fields in mugla province. no insecticide treatment was applied in all experimental fields throughout the production period in all experimental fields. the emerging leafminers and parasitoid adults were obtained an counted in the weekly sample leaves at laboratory. the parasitation rates were 32.01% for 2006 and 32.97% for 2007. the correlation coefficient was significantly positive between l. sativae and d. isaea population in both years (p< 0.01).
