The field complex techniques of the prevention and control of Neohendecasis sp.

在广西横县进行了人工释放赤眼蜂、喷施无公害生物农药、黑光灯诱杀成虫等技术协调组合防治茉莉花蕾螟的田间示范试验。试验结果表明 :处理区茉莉花农药残留降低 90 %以上 ,农药残留指标达到中华人民共和国农业行业标准NY5 0 1 7 2 0 0 1的要求 ;防治效果显著提高 ,防治成本降低 3 9.2 % ,为农户增收节支约 280 5 .0元 /hm2 。

The field exemplary experiment of the prevention and control of Neohendecasis sp.by the means of technical coordinate combination(including artificially releasing Trichogramma,spraying nuisance-free biotic pesticide,luring adult insects to their death with the lamp of black light,etc.)was conducted in the field of jasmine cultured in Heng county of Guangxi. The results showed that the pesticide residue of jasmine flowers in the treated region decreased more than 90%,the index of pesticide residue reached the requirement of the agricultural professional standard of the People’s Republic of China,NY5017-2001. The effect of the prevention and control improved significantly,the cost of prevention and control reduced 39.2%,the amount of return’s rising and expenditure’s reducing reached 2 805.0 RMB/hm^2.
