摘要
通过野外调查和室内外人工饲养,结果表明星天牛(Anoplophora chinensis(Forster))成虫期补充营养最喜欢取食苦楝树(Melia azedarach L.)。苦楝树饲养雌虫每头产卵在156～198粒之间,平均176.4粒,是木麻黄饲养的3.10倍,日平均产卵量是木麻黄饲养的1.57倍;取食苦楝树的雌虫寿命72～110d,平均91.8d;雄虫寿命88～125 d,平均103 d,雌、雄成虫分别比取食木麻黄(Casuari-na spp.)的多存活30.2和40 d。补充营养植物内总氨基酸、葡萄糖、果糖含量与成虫寿命和产卵量呈显著的正相关。研究结果与前人记载星天牛的产卵量为8～32粒,最多71粒,寿命一般40～50d 的报道有较大差异。
Field investigation and hand feeding Anoplophora chinensis(Forster)indoor and outdoor showed, that Cerambycid beetle in adult stage most liked bead tree as supplying nutrients.A female adult fed on bead tree oviposited 156～198 eggs,on an average 176.4 eggs,that was 3.10 times of that fed on Casuarina spp.,and the spawned amount each day was 1.57 times of the latter.Life span of female taking food on bead tree was 72～110 d,on an average,91.8%;Lif span of male was 88～125 d,on an average,103 d.Life spans of female and male were,respectively,30.2 d and 40 d more than that on Casuariua spp.Contents of general amino-acid,glucose and lerulose in supplement nutrient plants appeared positive correlation to life span and spawned amount of adult.There's a difference between the study and the former reports,in which spawned amount was 8～32 eggs and life span was 40～50 d.
