The red palm weevil, Rhynchophorus ferrugineus, is the most important internal quarantine pest in Iran. Injecting insecticides into the tree trunk is one of the methods for pest control. This research investigated the effect of cypermethrin (40% EC) and acetamiprid (20% SP) on controlling red palm weevil in a completely randomized design experiment with three replications. The treatments included a control (water injection) and injections of cypermethrin at concentrations of 2.5, 3.75-, and 5-mL L⁻¹, acetamiprid at concentrations of 5, 7.5, and 10 g L⁻¹, and combinations of the two insecticides. The insecticide injections were carried out in two stages. In the first stage, a hole was made in the tree trunk, and one week later, the second stage involved injecting the insecticides. The results showed that the injection of both insecticides significantly reduced the number of live larvae and adults, with the combined treatment of 5 mL L⁻¹of cypermethrin + 10 g L⁻¹ of acetamiprid leading to the lowest number of live larvae and adults. The combination of 5 mL L⁻¹ of cypermethrin + 10 g L⁻¹ of acetamiprid caused the highest adult mortality compared to 5 g L⁻¹ (77.02%) and 7.5 gL⁻¹ (87.37%) of acetamiprid. Additionally, combining the highest concentration of cypermethrin (5 mL L⁻¹) with different concentrations of acetamiprid resulted in the highest percentage of larval mortality. The results indicated that the combined injection of two insecticides proved highly effective and promising, making it suitable for integrated pest management (IPM) programs.
