气候变化对沈阳地区亚洲玉米螟发生世代的影响

Effect of Global Warming on Generations of Ostrinia furnacalis in Shenyang Region

对沈阳地区亚洲玉米螟落卵情况进行多年系统调查。结果表明,沈阳地区亚洲玉米螟年度落卵结束时间明显延长,已出现第三代卵,该世代幼虫可安全越冬,沈阳地区亚洲玉米螟由传统二代区转变为二、三代混生区。

In order to definite population dynamics between generations of Asian corn borer（ACB）, Ostriniafurnacalis（Guen6e）, the oviposition situations of Asian corn borer in Shenyang region were investigated systematically for years. The results showed that the end time of annual oviposition of Asian corn borer was significantly longer in Shenyang region; the third generation of egg has emerged, and this generation larvae can overwinter safely; Shenyang region was transformed from the traditional second generation into the two and three generations of mixed zone.
