摘 要：
2009年对湖北荆州、武汉、襄阳3个地区甜菜夜蛾(Spodoptera exigua)种群发生动态进行了系统监测与调查。结果表明,3个地区成虫始见期主要集中在5月中旬,终见期在11月下旬至12月下旬,成虫发生数量及动态变化存在较大差异。成虫发生数量从南到北呈递减趋势,荆州地区总诱蛾量分别是武汉地区和襄阳地区的1.35倍和12.50倍。武汉地区幼虫发生期最长178 d,其次是襄阳地区140 d,荆州地区幼虫发生期最短117 d;全年总发生量以武汉地区最多2 296头/百株,其次是荆州2 259头/百株,襄阳1 542头/百株。

摘 要：
The population occurrence of Spodoptera exigua was monitored and investigated systematically in Jingzhou, Wuhan and Xiangyang regions of Hubei province in 2009. The results showed that the adults were saw mainly in Mid-May firstly,and in late November to late December finally in the three regions. But the moth quantities and population dynamics were quite different in the different regions. The adult amounts of S. exigua in the three regions decreased with the latitude increasing. The total amounts of the moth in Jingzhou were 1.35 times of which in Wuhan and 12.50 times of which in Xiangyang respectively. The period of the larvae in Wuhan was the longest with 178 d, followed by the Xiangyang with 140 d, and Jingzhou was the shortest with 117 d. The annual volume of the larvae in Wuhan was also the most with 2 296 in100 host plants, followed by Jingzhou with 2 259, and Xiangyang with 1 542.
