| 摘 要： | 利用昆虫信息素对甜菜夜蛾田间种群动态进行监测,研究结果表明,昆明地区甜菜夜蛾发生从3月下旬开始上升,10月下旬下降,最高峰值出现在4～6月,冬季发生量小。大棚蔬菜作物幼虫发生高峰期为5～6月,露地蔬菜幼虫发生高峰期为6月;大棚切花作物上甜菜夜蛾幼虫周年发生,为害高峰期为6～9月。并根据种群动态分析得出,昆明地区甜菜夜蛾成灾原因除了甜菜夜蛾种群变化的扩散特点外,认为与昆明适宜的气候条件、栽培习惯和作物布局及防治措施等有关。

| Abstract: | The population dynamics of Spodoptera exigua by using the sex-pheromone from 2001-2003 in Kunming of China was monitored.The result indicated that it happened in each month.The number of adult begin increase from the last ten-day of March and decrease from the last ten-day of October,the main period of the month appeared from April to June.In winters,the number of adult was low.In the greenhouse vegetable crops the peaks of population happened from May to June.The number of adult happened in June on the lan... |
