摘要： 选用8种不同成分且经过室内毒力筛选的化学农药和生化农药单剂进行椰心叶甲[Brontispa longissima (Gestro)]田间防治，运用改进的直筒式手持简易喷雾器（水枪）进行施药，试验结果表明，啶虫脒、吡虫啉、高效氯氰菊酯、甲氰菊酯、丁硫克百威、阿维菌素、喹硫磷和氟虫腈在大田继续保持和室内相同的良好防治效果。施药后第7天、15天、30天和60天害虫虫口减退率和防效均大于99%，第90天和120天个别植株重新感染少量的椰心叶甲成虫和幼虫，第150天后有一半以上的植株感染椰心叶甲成虫和幼虫，其中个别植株已经产生卵和蛹，防效产生轻微下降，但不会对椰树心叶的生长造成实质性的影响。

Abstract: 8 different component pesticides were tested against Brontispa longissima (Gestro) in field, by using improved Zhitong sprayers. The results showed that acetaniprid, imidacloprid, Beta-cypermethrin, fenpropathrin, carbosulfan, abamectin, quinalphos and fipronil continued to maintain the same good control effect as indoor. The mortality and control effect are all over 99% after 7d,15d and 30d respectively, a small number of trees were infected coconut leaf beetle again after 90d and 120d respectively, most trees were found eggs and pupas after 150d , and the control effect had a slight decline, but will not cause a substantive impact on growth of center coconut leaves.
