颜色对枸杞木虱成虫引诱作用的研究

枸杞木虱Paratrloza sinica Yang＆Li．是枸杞主要害虫之一，刺吸危害枸杞叶片、花果，造成落叶、落果。目前，主要采用的化学农药防治方法，既污染环境，又影响了枸杞果作为营养保健品的价值。为了探索无污染的防治方法，本文在室外自然条件下，选用土黄、黄、橘黄、红、粉、天蓝、深蓝、褐、绿9种颜色作为引诱色，寻找对枸杞木虱成虫最具引诱能力的颜色。实验结果表明：土黄色、红色、黄色对枸杞木虱成虫的引诱作用显著。其他颜色（P=0．01）。特别是土黄的诱虫效果最明显。可以选土黄色作为引诱色诱杀枸杞木虱。而且，还可用色板监测枸杞木虱成虫的种群数量动态。

STUDY ON THE LURE FUNCTION OF COLORS TO THE Paratrioza sinica Yang & Li

Paratrioza sinica Yang & Li is one of the most important pests of wolfberry.Leaves and flowers and berries were damaged badly.Chemical control on the pest arose many problems such as environment pollution and debasement of the valuable of the berry.In order to find a new way to control the pest,nine kinds of colors,including loess,yellow,orange,red,pink,sky blue,dark blue,brown and green were selected as the lure color and tested outside door.The results showed the loess and orange and red have remarkable lure effect on the adult Paratrioza sinica Yang & Li.Specially loess lured many adult Paratrioza sinica Yang & Li and it could been used to control the pest.In addition,loess could been used to monitor the population dynamic of Paratrioza sinica Yang & Li.
