天牛科害虫主要以幼虫为害,在从事天牛害虫的调查、防治、口岸检疫等实际工作中,遇到的也大多是幼虫态。我国目前对天牛科幼虫的分类工作,尚未有系统的开展,对大多数天牛种类的幼虫不能识别,尤其对近似种的鉴别,更多困难,直接影响到天牛害虫研究工作的开展和质量。所以开展天牛科幼虫的分类工作,普及天牛幼虫的识别知识,很有必要。应用天牛幼虫特征鉴别种类,不但在实际工作中比较切合实用,而且可以补充、订正成虫分类的不足。在天牛科成虫的种级分类中,常用体表绒毛色采为分种特征之一。
Cerambycidae pests mainly larvae damage, engaged in the days of pests in the investigation, control, port quarantine and other practical work, the encounter is mostly larval state. At present, our country does not systematically carry out the classification of Cerambycidae larvae. It does not recognize most larvae of Cerambycidae, especially the identification of similar species and more difficulties, which directly affect the development of Cerambycites pest research quality. Therefore, it is necessary to carry out the classification work of Cerambycidae larvae and popularize the identification knowledge of Cerambycidae larvae. The application of the trait of larvae to identify the species not only practical in practical work, but also can supplement and correct the deficiencies of adult taxonomic classification. In the species of Cerambycidae, the commonly used body surface color is one of the sub-species characteristics.
