黄斑星天牛(Anoplophora nobilis G.)成虫白天活动,晚上静息,在10时和18时左右有两个活动高峰,主要为取食、交尾、产卵。成虫飞翔力不强,通常只在林间往返扩散,最远为1190米。其活动力的强弱主要受温度影响。正常活动范围为16°～28℃,32℃以上,10℃以下,活动失常。成虫多在胸径7～12厘米粗的树干上产卵,其高度随树龄而逐年上升至一定粗度的主、侧枝上。成虫特别嗜 在黑杨派及青杨派树种上取食产卵;白杨派树种上产卵少,表现出不同程度的抗虫性。对其它四旁树种也有一定的选择性,泡桐与臭椿是免疫的。成虫主要通过触角及下唇须等感觉器官来准确地选择树种。
Anoplophora nobilis G., which is active during the day and rests at night, has two peak activities at 10 o’clock and around 18 o’clock, mainly feeding, mating and spawning. Adults flying force is not strong, usually only spread back and forth in the forest, the furthest is 1190 meters. The strength of its activity mainly affected by temperature. The normal range of activities of 16 ° ~ 28 ℃, 32 ℃ above 10 ℃ below, abnormal activity. Adults more in the diameter of 7 ~ 12 cm diameter trunk spawning on the trunk, the height of each year with the age rose to a certain thickness of the main, collateral. Adults are particularly addicted to feeding on the Black Poplar and Green Poplar tree species; spawning tree species less spawning, showing varying degrees of insect resistance. On the other four species also have a certain selectivity, Paulownia and Ailanthus is immune. Adults mainly through the antennae and the lower lip and other sensory organs to accurately select the tree species.
