ECOLOGICAL STUDY ON Liriomyza trifolii (Burgess) AND ITS PARASITOIDS ON Vicia faba FIELD

Abstract: Field experiments were conducted Memofyia Governorate throughout 2004/05 and 2005/2006 seasons to study the population density and fluctuation of immature stages of the leaf miners on broad bean plants Vicia faba. Liriomyza bryoniae was appeared in some inspection as negligible numbers, so that the results presented in this work regard to Liriomyza trifolii. All immature stages of Liriomyza trifolii are permanent on leaves of broad bean during the growing period. Couning punctures, eggs, mines and numbers of larvae are
considered to be more suitable method of L. trifolii infestation. The number of L. trifolii pupae on broad bean samples are not suitable to give knowledge of L. trifolii population. Based on the overlapping numbers of peaks punctures eggs, mines and larvae were recorded on leaves samples of broad bean can be concluded that, L. trifolii had five or six generations occurred during the growing period.
Field and laboratory inspections no parasitoids played a role against L. trifolii. However, two eulophid parasitoids Diglyphus isaea and Chrysocharis parksi and bracond parasite Opius concolor have been found emerged from L. trifolii larvae and pupae. An initial rate of parasitism on L. trifolii larvae and pupae occurred early of growing period and then fluctuated increased or decreased during the both seasons. Parasitism percentage of D. isaea was highest than that O. concolor and C. parksi .
