摘　　要：比较了新近推出的新型杀虫剂莫比朗、吡虫啉和速扑杀防治柑桔矢尖蚧的效果。药后１周，３％莫比朗乳油和４０％速扑杀乳油１０００倍的防效相似，分别达到９６０９％和９７１２％，大大高于这两种药的其它参试浓度和１０％吡虫啉可湿性粉剂各浓度的防效。药后２周，它的防效仍达９０％以上，与４０％速扑杀乳油１０００倍效果相当。鉴于柑桔矢尖蚧发生代数多，每代发生期长，使用莫比朗防治时，药后１４天应再次施药。Comparison of control efficacy against citrus arrowhead scale among 3% Mospilan EC (acetamiprid),10% imidacloprid WP and 40% Supracide EC was done in 1998.The efficacies of control of 3% Mospilan EC at 1000x and 40% Supracide EC at 1000x were similar,respectively as 96.09% and 97.12%,much higher than those of other test concentrations of these two pesticides and all test concentrations 10% imidacloprid WP.The efficacies of 3% Mospilan EC at 1000x and 40% Supracide EC at 1000x 14 days were still higher than 90% after first application.Considering that there are several generations of citrus arrowhead scale in a growth season of citrus and each generation persists for long time,another application of 3% Mospilan EC should be suggested 14 days after first spraying it to make complete control.
