摘要
为有效绿色防控海南辣椒主产区3种传毒害虫的为害,以甜玉米YT29和抗蚜辣椒品种猪大肠ZDC及感蚜辣椒品种大羊角椒DYJJ为参试材料,系统开展辣椒与甜玉米间套作对3种传毒害虫的微生态调控效果研究。结果表明,ZDC-3/YT29和ZDC-4/YT29对桃蚜、棕榈蓟马、烟粉虱的微生态调控效果最好,虫害指数均显著低于ZDC-2/YT29、ZDC-1/YT29、ZDC单作及DYJJ-4/YT29、DYJJ-3/YT29、DYJJ-2/YT29、DYJJ-1/YT29及DYJJ单作;ZDC-2/YT29对桃蚜、棕榈蓟马、烟粉虱也具有较好的微生态调控效果,虫害指数均显著低于ZDC-1/YT29、ZDC单作、DYJJ-4/YT29、DYJJ-3/YT29、DYJJ-2/YT29、DYJJ-1/YT29及DYJJ单作;ZDC-1/YT29、DYJJ-4/YT29、DYJJ-3/YT29对桃蚜、棕榈蓟马、烟粉虱的微生态调控效果与ZDC单作无显著差异,但虫害指数均显著低于DYJJ-2/YT29、DYJJ-1/YT2及DYJJ单作。三亚、东方、儋州效果验证结果显示,ZDC-3/YT29和ZDC-4/YT29对桃蚜、棕榈蓟马、烟粉虱的微生态调控效果稳定,而ZDC-2/YT29的调控效果在三地存在显著差异。ZDC-3/YT29和ZDC-4/YT29间套作模式可广泛用于海南辣椒主产区3种传毒害虫桃蚜、棕榈蓟马、烟粉虱为害的微生态调控。
To effectively and greenly prevent and control three virus vector insects in the main capsicum production area of Hainan,microecological regulation and control effects on Myzus persicae,Thrips palmi,and Bemisia tabaci by intercropping capsicum with sweet maize were conducted with the sweet maize YT29,the aphid-resistant capsicum cultivar ZDC and the aphid-susceptible capsicum cultivar DYJJ as tested materials.The results revealed that ZDC-4/YT29 and ZDC-3/YT29 had the best microecological regulation and control effects on M.persicae,T.palmi,and B.tabaci,with average insect damage indices significantly lower than those of ZDC-2/YT29,ZDC-1/YT29,ZDC,DYJJ-4/YT29,DYJJ-3/YT29,DYJJ-2/YT29,DYJJ-1/YT29 and DYJJ.ZDC-2/YT29 also had better microecological regulation and control effects on M.persicae,T.palmi,and B.tabaci,with average insect damage indices significantly lower than those of ZDC-1/YT29,ZDC,DYJJ-4/YT29,DYJJ-3/YT29,DYJJ-2/YT29,DYJJ-1/YT29 and DYJJ.The effects of microecological regulation and control effects on m.persicae,T.palmi,and B.tabaci under ZDC-1/YT29,DYJJ-4/YT29,DYJJ-3/YT29,and ZDC were not significantly different,but the average insect damage index was remarkably lower than those under DYJJ-2/YT29,DYJJ-1/YT2,and DYJJ.Verifica-tion of the effects in Sanya,Dongfang,and Danzhou indicated that ZDC-4/YT29 and ZDC-3/YT29 had stable ecological regulatory effects on peach aphids,palm thrips,and tobacco whiteflies.However,there were significant differences in the regulation effects of ZDC-2/YT29 among the three regions.These results indicate that the intercropping model of ZDC-3/YT29 and ZDC-4/YT29 can be widely applied for microecological regulation and to control M.persicae,T.palmi,and B.tabaci in the main capsicum production area of Hainan.
