云南西双版纳傣族自治州允景洪县,属亚热带气候,终年无霜,夏热冬暖,年温差小,一年可以2—3熟,因而病虫种类繁多,稻螟的为害也很严重。 关于稻螟虫的种类,过去都认为只有二化螟、三化螟、大螟三种,但1962年12月及1963年1月在允景洪曼井兰合作社及思茅农校附近稻田进行越冬稻螟虫种类调查时,发现稻桩中有很多台湾稻螟的幼虫。在1,009条稻螟的活幼虫中,二化螟占39.85%,台湾稻螟24.70%、三化螟23.65%,大螟11.80%。 由此可见,允景洪地区不但有台湾稻螟,而且还相当重要。
Yunjing Xishuangbanna Dai Autonomous Prefecture Yunjinghong County, is a subtropical climate, year-round frost-free, hot summer and warm in winter, the temperature difference is small, one year can be 2-3 cooked, so a wide range of pests and diseases, the damage is very serious. In the past, only three species of rice stem borers, Borer, and Sesamia inferens were considered as rice borer species. However, in December 1962 and January 1963, winter rice was harvested in paddy fields near Yunjinghongmai Wellland Cooperative and Simao Agricultural School Stem borer species survey found that there are many rice piles in the rice borer larvae. Among the 1,009 live larvae of rice borer, the stem borer accounted for 39.85%, Taiwan borer borer 24.70%, Borer borer 23.65%, Sesamia inferens 11.80%. This shows that Yunjing Hong area not only Taiwan rice borer, but also very important.
