本文报道肉桂新钻虫——肉桂双瓣卷蛾的主要生物学特性;短期简易预测预报方法;在肉桂害虫卵上找到螟黄赤眼蜂,经人工大量繁殖后,两年来在西江林业局属下富石等10个林场800多亩肉桂林上释放,结果卵粒寄生率提高60.49—92.54％、肉桂枯梢率降低27.43—90.55％,效果良好。在药剂防治上亦找到50％巴丹水剂1000倍液或用2％巴丹粉亩用量2.5公斤,有显著保梢作用。
In this paper, we report the main biological characteristics of the new caterpillar, Cinnamomum cinnamomum cinnamomum, short-term simple prediction and forecasting method, the finding of Trichogramma ostriniae on the eggs of cinnamon pests. After large-scale artificial breeding, Under the rich stone and other 10 farms 800 acres of Guilin on the release of the results of the parasitic eggs increased 60.49-92.54%, cinnamon shoot rate decreased 27.43-90.55%, the effect is good. In the chemical control also found 50% of Bardan agent 1000 times or 2% of the total amount of powder with 2% Badan 2.5 kilograms, a significant role in preserving the tip.
