为探明长白山钙果蛀果害虫的主要种类和在本地区的发生规律,于花后一周开始悬挂诱捕器诱捕成虫,当诱到第一只成虫时地上部喷施药剂,以后每隔20 d喷施一次药剂,直到果实成熟前1个月为止,试验结果表明:梨小、李小是危害长白山钙果的两种主要蛀果害虫。梨小食心虫有3次羽化高峰,其中以第一、三羽化高峰期较长,第二个高峰期峰值较高但持续时间较短;李小食心虫第一、三两个羽化高峰期峰值较高,持续时间较短,第二个高峰期峰值较低,但持续时间较长。药剂防治以地上部喷施2.5%氯氟氰菊酯乳油3000倍液、20%氰戊菊酯乳油2000倍液防治效果最佳;同期喷施40%氧化乐果乳油1000倍液效果次之。
In order to find out the main types of fruit-boring pests in Changbai Mountain and their occurrence in the area, the traps were trapped by hanging traps one week after anthesis. The pesticides were sprayed on the shoots when the first adult was induced. Spraying an agent until 1 month before the fruit maturity, the test results show that: pear small, Li is harmful to Changbai Mountain calcium fruit two main bore fruit pests. Pear Mungbean has 3 feather peak, of which the first and the third feather peak is longer, the second peak is higher but the duration is shorter; the first and the third feather peak of beetle , The duration is shorter, the second peak is lower, but the duration is longer. Pharmacy control spraying 2.5% of cyhalothrin EC 3000 times, 20% fenvalerate EC 2000 times the best control effect; the same period spraying 40% omethoate EC 1000 times the second.
