通过野外调查和室内外人工饲养,结果表明星天牛[Anoplophorachinensis(Forster)]成虫大多在白天活动,在自然条件下有趋向木麻黄防护林带飞翔的行为。雌、雄成虫一生可多次交尾,每天8时和16时为交尾高峰。成虫补充营养最喜欢取食苦楝树(MeliaazedarachL.)。苦楝树饲养雌虫每头产卵156～198粒,平均176 4粒,是木麻黄饲养的3 10倍;取食苦楝树的雌虫寿命72～110d,平均91 8d;雄虫寿命88～125d,平均103d,雌、雄成虫分别比取食木麻黄(Casuarinaequi setifolia)的多存活30 2d、40d。幼虫主要集中在离地面40cm高度内的树干根际附近,占总虫数的94 8%。1年生林分受害株至第2年5月成虫羽化期死亡率最高,达66 7%,3～7年生林分有虫株率最高;7年生以下林分应重点防治。在生境条件相似的同龄林中,星天牛则喜欢危害基径较大的木麻黄,6cm以下的树则较少受害。
Through field investigation and artificial breeding indoors and outdoors, the results showed that adults of Anoplophorachinensis (Forster) mostly lived during the daytime and had the tendency to fly in Casuarina Shelterbelt under natural conditions. Female and male adults can be multiple mating life, daily 8:00 and 16:00 for the mating peak. Adult nutritional supplements are most preferred to Melia azadeht. Neem tree nests female 156-58 eggs per spawn, an average of 176 4, is Casuarina feeding 3 10 times; feeding neem tree female life expectancy 72 ~ 110d, an average of 91 8d; male life 88 ~ 125d , An average of 103d, female and male adults than feeding casuarina (Casuarinaequi setifolia) more survival 30d, 40d. The larvae were mainly concentrated near the rhizosphere of the trunk within 40 cm of the ground, accounting for 94.8% of the total number of insects. The mortality of 1-year-old stands until May of the second year was the highest in the eclosion period, reaching 66.7%. The highest stands were in the 3 ~ 7-year-old stands. The stands below 7 years old should be given priority to prevention and control. In similar habitats of the same age, Stellarean prefers to harm Casuarina, which has a larger base diameter, while trees under 6 cm are less affected.
