Abstract:
The agromyzid leafminers,
Liriomyza sativae
Blanchard and
L. trifolii
(B urgess) (Dip-
tera: Agromyzidae) are major pests that attack vegetables in Varamin, Tehran Province.
The parasitoids (Hymenoptera: Eulophidae) of these pests were investigated during 2003.
The leaf miner inf ested leaves were collected f rom different host plants, in particular cu-
cumber (
Cucumis sativus
L.,) and preserved under laboratory conditions until the parasi-
toids emerged. The vegetable leaf miner were parasitized by an expected range of parasi-
toids. The parasitoid species included

Although insecticides were applied con-
tinuously f or control of leafminers, the mean seasonal percentage of parasitism was
51.12% . The morphological characteristics of each species are given in brief .
