The chickpea pod borer, causing major damage to chickpea (Cicer arietinum L.) crops in most chickpea-growing regions of Iran and is a key pest of this yield. This study aimed to introduce and evaluate novel, effective insecticides as alternatives. The research was conducted using a randomized complete block design with five treatments and three replications in rainfed chickpea fields of Markazi, Kermanshah, and West Azerbaijan provinces. Treatments included two concentrations of chlorantraniliprole (150 and 100 mL/ha), thiodicarb (750 g/ha), indoxacarb (250 mL/ha), and control (water spray). Sampling of live larvae was performed one day before spraying and 3, 7, and 14 days after insecticide application. The results showed that all tested insecticides were effective. On the seventh day after application, chlorantraniliprole at 150 mL/ha showed higher efficiency than other treatments by 95.8% ± 2.1, 86.4% ± 2.4, and 92.3% ± 4.6 in West Azerbaijan, Markazi, and Kermanshah provinces, respectively. Additionally, assessment of damaged pods revealed that in Markazi province, application of chlorantraniliprole at 150 mL/ha resulted in the lowest damage percentage. In Kermanshah province, indoxacarb followed by chlorantraniliprole at 150 mL/ha, proved to be the most effective while in West Azerbaijan province, both thiodicarb and chlorantraniliprole at 150 mL/ha were the most successful in minimizing pod damage. According to the obtained results, chlorantraniliprole is recommended for inclusion in management programs of this pest in chickpea fields. [ABSTRACT FROM AUTHOR]
