沟金针虫(Pleonomus canaliculatusFaldemann)和细胸金针虫(Agriotesfuscicollis Miwa)是我国北方农田两种重要的地下害虫。前者分布于我国北纬32—34°,东经106—123°;后者分布于我国北纬33—50°,东经98—134°;且存在很大区域的混生重叠。 武功地区两种金针虫均有分布。60年代以前,沟金针虫占绝对优势。70年代以来,细胸金针虫逐渐增多,至80年代以来,沟金针虫在不少田块中近乎绝迹,细胸金针虫成为武功地区金针虫类的优势种群(见表1).本文拟就沟金针虫和细胸金针虫在武功地区种群演替的原因做一初步探讨,供商榷。
Pleomotis canaliculatus Faldemann and Agriotes fuscicollis Miwa are two important underground pests of farmland in northern China. The former is distributed in China’s north latitude 32-34 °, longitude 106-123 °; the latter located in China 3350 ° north latitude, longitude 98-134 °; and there is a large area of mixed overlap. Wugong area two kinds of golden worm are distributed. Before the 1960s, Gougeons dominance. Since the 1970s, the fine-pinged pinworm has gradually increased. Since the 1980s, the genus Goneria is almost extinct among many of the plots, and the fine-pointed pinworm has become the predominant species of the genus Gypsophila in the area of Wugong (see Table 1) Gully needleworm and pinworm pinworm in the martial arts population succession to do a preliminary discussion for the sake of discussion.
