枣园绿盲蝽生物学特性研究

为有效控制绿盲蝽Apolygus lucorum Meyer-Dür的危害,在沧州金丝小枣产区对其生物学特性进行了研究。结果表明:绿盲蝽羽化后1～2 d即可交尾产卵,平均每雌产卵286粒;若虫孵出1～2 min即可爬行,3龄若虫在空气相对湿度60%的条件下可耐饥饿35～47 h;成虫于果实膨大期开始转移到其它寄主如豆类、蔬菜、杂草和棉花等植物上继续危害,7月初进入转移高峰期,9月上旬开始出现裂果时又迁回枣树,危害裂果和嫩叶,并产卵越冬;绿盲蝽成虫受扰时1次飞行距离为3～9 m,主动迁飞时为2～5 m;绿盲蝽成虫对黄绿色趋性最强,其次为黄色、红色。

Bionomics of Apolygus lucorum in Jujube orchards

The bionomics of Apolygus lucorum Meyer-Dür in golden silk jujube orchards in Cangzhou were studied to control its damage.The result showed A.lucorum began to mate 1 or 2 d after the emergence.The average egg number was 286 per female.The nymph crawled 1 or 2 min after hatching.The nymphs in the 3rd instar could survive 35-47 h without food under the condition of 60% relative humidity.The adults began to transfer to other hosts such as weeds,cottons,beans and vegetables to keep on harming with a peak in the beginning of July,moved back on the jujube trees to damage the cracking fruits and tender leaves in the first ten days of September and oviposit on the trees to prepare for overwintering.The adult could fly 3-9 m when disturbed and its active migration distance was 2-5 m.It mostly prefered yellow-green color.Yellow and red were the next.
