Abstract :

The leaf miner Agromyza sp. is one of the most important pests of chickpea. Seasonal fluctuation of percent parasitism of the pest was investigated on chickpea in Khomeyn,Iran in 2009. Samples were taken on two days a week and number of larvae and parasitized larvae per plant were counted parasitism laboratory. The parasitoids emerged from larvae were identified. The highest percent was 18.8 on June. 29 In this experiment the parasitoids activity and the peak of leaf miners larvae population were in the same time in khomeyn region. In probability level 0.05, the regression between number of leaf miners larvae and % parasitism was positive and significant (R2=0.6).
