The mature larva and pupa of and the mature larva of are described for the first time. The larvae of and are re-described. Five larval instars were determined in , thereby correcting doubtful data in the literature. The relationship between larval growth, number of larval instars, head width of the mature larva, and the adult weevil is explained using the example of . The nearly constant ratio of subsequent larval instars in head width ratio, termed "growth factor" and derived from Dyar's ratio, is used for the determination of larval instars. Larval collecting and breeding data are discussed in relation to their significance for the clarification of life-cycles.
首次描述了[物种名称1]的成熟幼虫和蛹以及[物种名称2]的成熟幼虫。重新描述了[物种名称1]和[物种名称2]的幼虫。确定了[物种名称3]有五龄幼虫,从而纠正了文献中的可疑数据。以[物种名称3]为例,解释了幼虫生长、幼虫龄数、成熟幼虫头宽与象甲成虫之间的关系。从戴尔比率得出的头宽比率中,后续幼虫龄数几乎恒定的比率,即“生长因子”,用于确定幼虫龄数。讨论了幼虫采集和饲养数据对阐明生命周期的意义。
