小菜蛾是武汉郊区造成十字花科蔬菜减产的主要害虫。1976年我们以青菱公社建河大队、长丰公社东风大队、和平公社五丰大队为试验点,以点带面,推动了小菜蛾的大面积综合防治工作。据不完全统计,除了合理安排茬口,铲除杂草,清除田间残株败叶,大搞田园清洁等措施外,共安装黑龙灯400余盏,放置性引诱钛3,000多个,利用微生物农药防治20,000多亩,纠正了盲目使用化学农药的偏向,保护和利用了自然天敌,综合防治面积达30,000余亩,收到了较好的效果。贫下中农满意地说:今年是“两低一高”。即虫口密度低,用药少成本低,产量高。
Plutella xylostella is a major insect pest causing the decrease of cruciferous vegetables in the suburbs of Wuhan. In 1976 we Qingling commune Jianhe Brigade, Changfeng commune Dongfeng Brigade, Peace Corps Fung Fung Brigade as a pilot, with a point to promote the large-scale comprehensive prevention and treatment of diamondback moth work. According to incomplete statistics, a total of more than 400 lamps of black dragonflight were installed, more than 3,000 were seduced by titanium, and more than 20,000 were used to control the use of microbial pesticides in addition to rationally arranging stubble crops, eliminating weeds, eliminating stubborn leaves in the field and promoting pastoral cleanliness. Mu, corrected the biased use of chemical pesticides blindly, protected and utilized natural enemies, and the comprehensive prevention and control area reached 30,000 mu and received good results. Poor middle peasants said with satisfaction: This year is “two low and one high.” Insect population density is low, low cost of medication, high yield.
