Abstract:
The rice striped stem borer, Chilo suppressalis (Walker) (Lepidoptera: Crambidae), is one of the most destructive and economic pest of rice worldwide. Numerous reports of high level of resistance in C. suppressalis population of northern Iran as well as considerable environmental impact of Diazinon have been existed. Recently, Chlorantraniliprole (Anthranilic diamide) and Flubendiamide (Phathalic acid diamide), a novel group of insecticides, have been widely used to control several lepidopterans, such as C. suppressalis. The field experiment was carried out to evaluate the efficiency of Chlorantraniliprole 0.4 G, (12.5 kg/ha), Flubendiamide 20 WG, (0.9 kg/ha), Dinotefuran 20 SG, (0.75 kg/ha) and Thiomethoxam 25 WG, (0.2 kg/ha) against C. suppressalis. Treatments were conducted in randomized block design with three replications in experimental paddy fields of Rice Research Institute of Iran, Guilan province, during 2018-2019. The overall data indicated that at 6 and 12 days after first treatment the efficiency of Chlorantraniliprole was recorded to be 95.90% and 98.52% followed by Flubendiamide (93.43% and 96.97%), Dinotefuran (90.29% and 94.31%) and Thiomethoxam (55.09% and 79.60), respectively. Furthermore, at 6 and 12 days after second treatment, the efficiency of Chlorantraniliprole was 93.97% and 98.32% followed by Flubendiamide (88.99% and 97.51%), Dinotefuran (79.94% and 88.90%) and Thiomethoxam (27.37% and 40.62%), respectively. Moreover, larval population decreased in last sampling and had positive correlation with efficiency of Chlorantraniliprole 0.4 G, Flubendiamide 20 WG and Dinotefuran 20 SG. It seems that Chlorantraniliprole 0.4 G followed by Flubendiamide 20 WG and Dinotefuran 20 SG were effective in the management of rice striped stem borer.
