不同诱捕器对油松毛虫性引诱剂诱虫量的影响

Effect of different traps on the insect trapping of sex attractant of Dendrolimus tabulaeformis

油松毛虫是我国辽宁省油松林中的主要害虫,每年都有大面积的发生,给松林生存和生态建设安全造成了严重威胁。为了更好地使用性引诱剂防治,本文在辽宁省建平县通过林间诱捕试验,以油松毛虫性引诱剂为诱芯,比较了不同形状、不同颜色、不同悬挂高度的诱捕器对油松毛虫雄成虫的诱虫量。结果表明,4种形状诱捕器的诱虫量由高到低依次为:大船型诱捕器、三角型诱捕器、小船型诱捕器和桶型诱捕器;大船型与小船型和桶型的差异显著,与三角型的差异不显著。小船型与桶型的差异显著,与三角形的差异不显著。3种颜色诱捕器对油松毛虫雄成虫的诱虫量由高到低依次为:黑色诱捕器、绿色诱捕器、白色诱捕器;黑色诱捕器和白色诱捕器的诱虫量存在显著性差异;而绿色诱捕器与黑色诱捕器和白色诱捕器之间差异性不显著性。3种悬挂高度诱捕器的诱虫量由高到低依次为:悬挂高度为1.7 m的诱捕器,悬挂高度为3.1 m的诱捕器,悬挂高度为2.4 m的诱捕器;悬挂高度为1.7 m的诱捕器诱虫量与其余2种悬挂高度的诱捕器诱虫量差异性显著;悬挂高度为2.4 m的诱捕器诱虫量与悬挂高度3.1 m的诱捕器诱虫量差异性不显著。本文主要对不同诱捕器形状、颜色、悬挂高度3个因素利用正交试验方法进行了组合试验,并比较了组合诱捕器的诱虫量,得出诱虫量最大的是悬挂高度为1.7 m的绿色大船型诱捕器,建议在生产实践中推广该组合。

Dendrolimus tabulaeformis is the main insect pest in the Pinus tabulaeformis forest in Liaoning Province. It is a key target of pest control over the years. In order to make better use of sex attractant,in Jianping County of Liaoning Province, a trap test was carried out in the forest, and the lure of D. tabulaeformis was used to induce the insect-trapping of the male adults of D. tabulaeformis with different shapes,different colors and different hanging heights. In this paper,the trapping quantity of four kinds of traps was discussed,and the results showed that the number of lures was from high to low：large ship traps,triangular traps,boat-type traps and bucket-type traps. The difference between big shiptype and boat type and bucket type was significant, and the difference with triangle type is not significant. The difference between boat type and bucket type was significant,and the difference with triangle was not significant. The trapping capacity of three kinds of color traps for male adults of D. tabulaeformis was from high to low： the black trap,the green trap,the white trap,the trapping quantity of the black trap and the white trap had significant difference,and the difference between the green trap and the black trap and the white trap was not significant. The lure of three kinds of hanging height traps was from high to low： a trap with a height of 1. 7 m,a trap with a height of 3. 1 m,a trap with a height of 2. 4 m; The trapping quantity of the trap with the height of 1. 7 m was significantly different from that of the other 2 kinds of hanging heights. There was no significant difference between trapping quantity of trap with 2. 4 m and height 3. 1 m of trap. This paper mainly used orthogonal test on the different shape of the trap,color,height of suspension three factors to carry out the combination test,and compared with the combination of trapping insects,the biggest lure is the big ship-type,green traps,suspension height of 1. 7 m,recommended in the production of the promotion of this combination.
