2012—2014年对新疆阿克苏地区枣树与核桃树黄刺蛾幼虫的发生为害消长动态进行了调查。结果表明,黄刺蛾幼虫在本地区核桃树上的发生为害重于枣树;在5 m高的核桃树上,黄刺蛾幼虫更趋于在距离地面1~3 m的区域范围内为害;每年幼虫发生期均有两个高峰,分别在7月中旬和8月中、下旬,2014年受5—8月平均气温较低(与2012—2013年同期相比,低1~2℃)天气影响,幼虫发生期推迟了约两星期。 2012-2014 on the occurrence of jujube and walnut Trichoplusia larvae in Xinjiang Aksu region dynamics were investigated. The results showed that Trichoplusia larvae were harder on jujube trees in the region than on jujube trees. On the 5 m tall walnut trees, Trichophaea baritx larvae tended to be damaged in the range of 1-3 m from the ground. The annual larvae have two peaks each in mid-July and mid-August, respectively. In 2014, the average temperature in May-August was lower (1 ~ 2 ℃ lower than the same period in 2012-2013) Affected, larvae delayed by about two weeks.
