The Sperm Structure and Spermatogenesis of Trypophloeus klimeschi (Coleoptera: Curculionidae: Scolytinae)

摘要

In the mating, reproduction, and phylogenetic reconstruction of various insect taxa, the morphological characteristics of the male reproductive system, spermatogenesis, and sperm ultrastructure are important. We investigated these morphological characteristics of Trypophloeus klimeschi (Coleoptera: Curculionidae: Scolytinae), which is one of the most destructive pests of Populus alba var. pyramidalis (Bunge) using light microscopy, scanning electron microscopy, and transmission electron microscopy. We also compared these morphological characteristics with that found in other Curculionidae.
