Abstract:
The leaf miner with several species is one of the most important pests of the wide range of plants, including chickpea. They damage host crops in adult stage by making small cavities on plant leaf for oviposition and in the larval stage by creating spiral mines through the leaves. This study was conducted to determine the efficacy of some insecticides including Cyromazine 75%wp 600 and 800 mL/L ( 200and 250 g/ha), Abamectin EC1.8% 200 ml/l, Chlorpyrifos EC 40.8% (600 ml/l) and the control on the pest. All the experiments were conducted in a completely randomized block design with 4 replicates in three provinces, including Kurdistan, Kermanshah and Lorestan. To obtain a uniform sampling method, in each plot, 10 leaves with equal size were randomly collected from the middle part of the plants and were placed in separate plastic bags labeled with treatment name and number of replications was transferred to the laboratory. The number of alive larvae in the mines was counted using a stereomicroscope and data was analyzed by SAS software. The results showed that although there was no significant difference between the treatments after spraying and all used pesticides were effective compared with the control, Cyromazine (250 g/ha) and Chlorpyrifos 14 days after application in Lorestan with (95.08±2.87% and 100%) in Kermanshah with (88.17± 1.82% and 83.17±8.83%) and in Kordestan with (100% and 100%) had the highest efficiency among the treatments. In addition, in terms of percentage of infested plants at the end of the season, the Cyromazine (250 g/ha) treatment in Kermanshah province and by Chlorpyrifos and Cyromazine (250 g/ha) treatments in Lorestan province showed the least infestation compared with that of other treatments.
