摘要
竹斑蛾幼虫取食石竹竹叶,是石竹的主要食叶害虫之一。近年来,受不合理的经营与防治措施影响,竹斑蛾已成为石竹主要食叶害虫,为践行绿色发展理念,筛选出防治竹斑蛾的有效药剂,探讨无公害防治竹斑蛾的路径,2018年在福建省三明市郊国有林场石竹林中采用喷粉技术喷施1.1%苦参碱粉剂,用量22.5 kg/hm^2,采用喷烟技术,施放5%桉油精可溶液、1.2%烟碱·苦参碱乳油和碧绿1%苦参碱,用量均为750 mL/hm^2,开展对竹斑蛾3龄幼虫林间防治试验。结果表明:药后2 d,参试药剂的防治效果均超过90%。表明4种参试药剂均有高效的杀虫效果,可在防治竹斑蛾幼虫为害时应用。
The larvae of Artona funeralis is one of the main defoliators of Phyllostachys nuda,which eat Ph.nuda leaves for living.In recent years,under the influence of unreasonable management and pest control,A.funeralis has become the main leaf eating pest.In order to practice the concept of green development,screen out the effective pesticide to control the defoliator,and explore the path of pollution-free control and treatment of A.funeralis,the study adopted in 2018 powder spraying technology to spray the 1.1%matrine powder,with the dosage at 22.5 kg/ha,and also the smoke spraying technology to apply 5%Eucalyptus oil fine solution,1.2%Nicotine·Matrine Emulsion and Turquoise 1%Matrine,with the dosage at 750 mL/ha,for 3-age A.funeralis larvae control experiment in Sanming Suburb National Forest Farm,Fujian Province.The result showed that the control ratio of the pesticides was above 90%after 2 d,which indicated that all 4 kinds of tested agents had the effective insecticidal effect and could be used to control A.funeralis larvae when the pest erupts.
