摘 要: 报道了9种杀虫剂防治椰心叶甲成虫的药效试验,试验结果表明:化学农药2.5%高效氟氯氰菊酯EC、2.5%三氟氯氰菊酯EC、10%吡虫啉WP对椰心叶甲的防治效果高,防效均在90%以上;生物农药1.8%阿维菌素EC、0.3%印楝素EC对椰心叶甲有一定的控制作用,但效果不理想。 Efficacy experiments were conducted in controlling Brontispa longissima adults with nine insecticides. Beta-cyfluthrin 2.5% EC, cyhalothrin 2.5% EC, and imidacloprid 10% WP showed high efficacy against Brontispa longissima, with control greater than 90%. Control of Brontispa longissima provided by the biopesticides, abamectin 1.8% EC and azadirachtin 0.3% EC, was not acceptably high.
