摘要： Pseudoregma bambucicola is a highly reproductive bamboo aphid that affects the normal growth of bamboos, induces the formation of sooty molds, and even causes substantial injury or death among young bamboos. Objective: To identify the most effective chemical synthesis of drugs to control this aphid. Methods: This study compared the aphicidal activities of three prevention and treatment drugs, namely, cypermethrin, deltamethrin, and imidacloprid, against P. bambusicola. Results: Imidacloprid demonstrated the greatest insecticidal efficacy in the in vitro experiments by killing 83.33% of the aphids within 6 h. Cypermethrin and deltamethrin only killed 33.33% and 70% of the aphids, respectively, within the same duration. Therefore, we used deltamethrin and imidacloprid in the field test. The amount of aphids significantly decreased four days after applying deltamethrin, and the treatment rate reached 39.67%. The amount of bamboo aphids was significantly reduced in the second treatment. The treatment rate reached 81.67% on day 12 and reached 100% on day 30. Favorable results were achieved in the imidacloprid group, in which the amount of bamboo aphids was significantly decreased, and a 100% treatment rate was achieved on the 12th day after the treatment. Conclusion: Imidacloprid demonstrates the best aphicidal activity.
