几种植物源杀虫剂防治黑竹缘蝽效果分析

黑竹缘蝽是绿竹等丛生竹笋期的主要害虫,为拓宽防治黑竹缘蝽新途径,制定高效、经济、环保的防治措施,研究了5种植物源杀虫剂对黑竹缘蝽若虫的防治效果。结果表明:选用1.3%苦参碱可溶液剂、0.5%藜芦碱可溶性液剂、4%鱼藤酮乳油、1.2%烟碱苦参碱乳油、1%苦皮藤素乳油,运用弥雾机喷雾防治黑竹缘蝽若虫,药剂原药用量均为1 200 mL/hm²,药后3 d防治效果均可达90%以上,达到了有效控灾的目的。这5种药剂可用于无公害防治黑竹缘蝽若虫,试验结果可为生产上制定黑竹缘蝽若虫防治措施提供借鉴。

Analysis of the Effect of Several Plant Origin Insecticides on Notobitus meleagris Control

Notobitus meleagris is the main threat to Dendrocalamopsis oldhami in its shooting period. In order to find the new way to prevent and control N. meleagris and develop a high efficient, economic, and environmentally friendly control measures, the paper studied control effects of 5 insecticide of plant origin on N. meleagris. The results showed that he prevention measures of environmental protection, from the side of pollution-free control N. meleagris, and analyses the influence of several kinds of botanical insecticides N. meleagris nymphae control effects, the results showed that 1. 3% matrine soluble liquid agent, 0.5% veratrine soluble liquid agent, 4% of rotenone oil and 1.2% nicotinamide and 1% matrineec could be mixed and sprayed on N. meleagris nymphs with atomizing sprayer. The pharmaceutical technical dosage was 1 200 mL/hm², and the control effect 3 d later after the spray could be above 90%, which can achieve effective control. The 5 insecticides could be used for pollution-free control of N. meleagris nymphs, and the test results would be the references for N. meleagris nymphs prevention and control in production.
