摘要
悬铃木方翅网蝽在济宁地区1年发生4至5代,4月中旬越冬成虫上树为害,5月中旬第1代成虫发生,第2代开始世代重叠,10月中下旬第4或5代成虫开始越冬。通过22.5%敌敌畏OL、25%吡虫啉WP、5%啶虫脒EC及4.5%高效氯氰菊酯EC4种药液3种浓度(1000倍、2000倍、3000倍)及清水对照防治试验表明,施药1d后校正防效为76.72%~87.86%,3d后,校正防效为86.96%~98.30%,5d后,校正防效为89.52%~98.49%,具有较好的速效性。2.5%敌敌畏OL的校正防效相对较高,25%吡虫啉WP次之,但每种药剂的3种浓度处理的防控效果间均不存在显著性差异。
The live history of Clostera Anaehoreta(Say), there were 4 or 5 generations each year in Jining .The overwintering adults begain to damage in middle April, the adults of first generation were found in middle May,and the overwintering adults could survive on trunks and branches in middle and late October.The generations overlapping was obvious from the seond generation. Five treatments including Dichlorvos (22.5 %, OL), Imidacloprid (25% ,WP), Acetamiprid (5 %, EC), Beta cypermethrin (4.5 %, EC) and contrast were designed to make the effect test of controlling Clostera Anaehoreta. The control effects after treated 1,3,5 days were 76.72%~87.86%, 86.96%~98.30% and 89.52%~98.49% respectively, they had a good quick --acting. Dichlorvos had the best control effect, and Imidacloprid was the next one. But there were not very significant differences on the control effect among the different concentrations of every pesticide, after treated 1,3 or 5 days.
