山地橄榄星室木虱防治初报

应用不同药剂、浓度对橄榄星室木虱(Pseudophacopteron canariumYang et Li)进行室内毒力测定和林间防治试验,结果表明:2.5%功夫菊酯乳油对橄榄星室木虱的毒力最高,其相对毒力是苦.烟乳油的1.7倍;复合药剂的防效明显高于单一药剂,最佳组合以功夫乳油5 500倍液+木虱净乳油6 000倍液+苦.烟乳油5 000倍液林间喷雾效果最佳,药后3 d、7 d、14 d、21 d的防效分别为73.63%、90.54%、93.51%、95.43%;连续施用复合药剂7 d的防效达100%,不仅防治效果好,而且持效长,可有效地控制星室木虱的危害。

Preliminary Report on Controlling Pseudophacopteron canarium from Olive on the Mountain land

The results showed that 2.5% of lambda-cyhalothrin EC had the highest toxicity to Pseudophacopteron canarium, whose relative toxicity was 1.7 times as large as martrine EC relative toxicity; the compound medicament control effect was evidently higher than the singular medicament control effect, the effect of spraying with the combination of 5 500 times of lambda-cyhalothrin EC+6 000 times of beta-cypermethrin EC+5 000 times of matrine EC in forest was optimal, the control effects were 73.63%,90.54%,93.51%,95.43% respectively after3,7,14,and 21 days of spraying; the control effect reached 100% with spraying the compound medicament constantly for 7 days, its control effect not only was good, but kept for a long time, it could control P. canarium damage effectively.
