不同保存方法对角倍蚜性蚜数量和存活率的影响

Influence of Different Preserve Methods for the Sexuale Number and Survival Rate of Chinese Horned Gall Aphid, Schlechtendalia chinensis (Bell)

  • 摘要: 比较了不同类型虫袋和填充物对角倍春迁蚜产性蚜数量和存活率的影响,结果表明:采用柱状虫袋填充玉米苞皮及对玉米苞皮进行浸泡处理可以提高性蚜的数量和雌蚜/干母的存活数;与传统的三角纸袋填充棕丝相比较,柱状虫袋填充浸泡玉米苞皮的雌蚜数、雌蚜/干母存活数、雄蚜数和性蚜总数分别增加了107.6%、229.1%、71.1%和87.5%,雌蚜/干母存活率提高了21.1%。虫袋内的雌蚜数、雄蚜数和性蚜总数与春迁蚜数呈显著负相关;雌蚜数和雌蚜/干母存活数与雄蚜数、性蚜总数和雌雄性比分别呈极显著正相关。角倍产区的环境因子明显影响春迁蚜的羽化期,但对春迁蚜产性蚜的数量没有明显影响。

     

    Abstract: Different preserve methods for the sexuale number and survival rate of Chinese horned gall aphid, Schlechtendalia chinensis (Bell), were examined. The results demonstrated that the columnar aphid bag filled with corn husks increased the sexuale number and survival rate of sexuale. Compared with the triangle-shaped aphid bag filled with palm fibre, the sexual female number, sexual female/fundatrix survival number, sexual male number and total sexuale number of the columnar bag filled with corn husks increased by 107.6%, 229.1%, 71.1% and 87.5%, respectively; and the female/fundatrix survival rate increased 21.1% at the same time. The numbers of sexual female, sexual male and sexuale of the aphid bags had significantly negative correlations with the spring migrant number. The sexual female/fundatrix number and survival number had significantly positive correlations with the sexual male number, sexuale number and the female and male ratio. Environmental factors could influence the emergence period of spring migrant aphid obviously, but could not influence the sexuale number.
