芦竹复盾蚧生物学特性观察与防治方法研究

Observation on Biological Characteristics and Control Methods of Duplachionaspis Stanotophri

2017年3月—2018年6月,在浙江临安对芦竹复盾蚧进行生物学特性观察以及化学防治试验。试验结果表明4月—11月上旬是初孵若虫活跃期和药剂防治的关键时期。注射2倍的5%吡虫啉乳油和40%乙酰甲胺磷乳油,防效分别为95.4%和95.6%;使用800倍的2.5%功夫乳油和40%毒死蜱乳油液,对竹冠喷雾防治的防效分别90%和91.6%。竹腔注射法和喷雾法均有较好的防治效果,施药后雷竹上芦竹复盾蚧数量明显减少。

From March,2017 to June,2018,the biological characteristics and chemical control experiments of duplachionaspis stanotophri are carried out in Lin ’an,Zhejiang.The results shows that April to early November is the active period of newly hatched nymph,which is the key period of chemical control.Using 2 times of 5% imidacloprid EC and 40% acephate EC for injection,the control effect is the best,with 95.4% and 95.6% respectively.Using 800 times of 2.5% cyhalothrin EC and 40% chlorpyrifos EC,the control effects of bamboo crown spray are 90% and 91.6% respectively.Both injection and spraying methods have good control effects,and the number of physarum arundinacea on duplachionaspis stanotophri decreased obviously after application.
