Evaluation of Diglyphus isaea (Hymenoptera: Eulophidae) (Miglyphus®) for biological control of Liriomyza sativae (Dip.: Agromyzidae) on Greenhouse cucumber

was conducted weekly and the second plot was considered as the control (no pest control measures applied). The total number of mines (mean±SE) bearing live and dead larvae and parasitism percentage of leaf miner larvae/plant were 26.61±5.54, 35.32±7.42 and 39.00±7.00, respectively in release treatment of the first greenhouse. The same parameters estimated to be 95.37±12.95, 4.60±0.92 and 5.00±2.00, respectively for the control at the same greenhouse. Similarly, in the second greenhouse above mentioned parameters for release treatment (3.16±0.66, 4.69±0.92 and 40.00±7.00 respectively), was significantly different with those of the control (12.83±1.63, 1.89±0.60 and 8.00±2.00). The activity of parasitoid was increased following the increase of ambient temperature and pest population at the end of the sampling period.
