摘要
桉树翘喀木虱以成虫和若虫刺吸桉树新梢嫩叶,严重时造成新梢枯死,影响树木的生长、发育。该虫在福建闽南1 a发生6代,若虫5龄,以若虫在嫩梢叶腋和当年新萌未展开新叶中越冬。越冬代历期193-230 d,其他世代历期46-52 d。该虫具有明显趋嫩性。采用不同药剂防治试验表明,阿维菌素、吡虫啉、辛灭利、爱诺虫清、尿洗合剂等药剂对桉树翘喀木虱均具有较高的防治效果,1.8%阿维菌素乳油1500-3000倍稀释液、5%吡虫啉1000-2000倍稀释液以及洗衣粉、尿素、水按0.2∶0.1∶200混合液防治效果均在90%以上,但阿维菌素、尿素与洗衣粉更生态环保,适宜推广应用。
Cacopsylla licina Li et Yang attacks new top and tender leaf of eucalyptus. The new tops of eucalyptus will wither when harmed seriously. It occurs six generations 1 year, lives through the winter in shoot and new buds with nymphae. Each generation last 46 - 52 days , besides the overwintering one lasts 193 to 230 days. It is obvious that the pest likes tender branch. The conspicuous control effects are gained with toxicants such as abamectin, imidacloprid gave, Phoxim ＋ Fenpropathrin,E. C. i, Avermectins solution, mixture of laundry detergent and carbamide. 1.8% abamectin latex with 1500 to 3000 times, 5% imidacloprid latex with 1500 to 3000 times and the mixture of laundry detergent , carbamide and water （0.2： 0.1： 200） are all above 90%. Among them, 1.8% abamectin latex and mixture of laundry detergent and carbamide, as the biological medicament, are more suitable to extend and apply.
