棉铃虫Helicoverpa armigera(Hübner)是我国最严重害虫之一。为了提高监测和诱捕效率,2009年在山西和新疆进行2种性诱芯诱捕棉铃虫的田间试验,2种性诱芯分别来自中国科学院动物研究所和北京中捷四方公司,2种诱芯处理分别重复2次和6次,诱捕器分别为水盆和笼罩。试验结果:在山西试点,动物所诱芯的诱蛾数是中捷四方公司的8.60倍;在新疆试点,则达到11.89倍。以上差异均达极显著水准(P<0.01)。同时,在山西试点,动物所诱芯的有效期长达62d,比中捷四方公司的长14d。据此认为动物所棉铃虫性诱芯值得应用推广。
Helicoverpa armigera (Hübner) is one of the most serious pests in our country. In order to improve the efficiency of monitoring and trapping, two kinds of trap-induced trapping cotton bollworm were conducted in Shanxi and Xinjiang in 2009. Two kinds of induced traps were obtained from Institute of Zoology, Chinese Academy of Sciences and Beijing Zhongjie Sifang Company respectively. Repeated 2 and 6 times, respectively, traps were basin and shrouded. Test results: In the Shanxi pilot, the number of entrained moths in animals was 8.60 times that of the four companies in Zhongjie; in Xinjiang, it reached 11.89 times. The above differences were significant levels (P <0.01). At the same time, in Shanxi pilot, animals induced by the effective period of up to 62d, 4d longer than the Czech Republic, the Quartet. According to that, the animal bollworm sexual attraction worthy of promotion.
