The larval parasitoid Bracon (Uncobracon) apoderi Watanabe (Hymenoptera: Braconidae) is reported from Kyushu for the first time. Two host weevils, Phymatapoderus latipennis and Paroplapoderus pardalis (Coleoptera: Attelabidae), are newly recorded. Bracon apoderi parasitized three attelabid species, including Apoderus balteatus, but did not parasitize Cycnotrachelus roelofsi even though it is a dominant attelabid species in the study site. In addition, B. apoderi mainly parasitized suspended cradles rather than cut‐off cradles. 相似文献

To contribute to the understanding of the genus Ostrinia (Lepidoptera; Pyralidae) in Japan, we collected larvae of Ostrinia spp. from known host plants and plants not recorded as hosts, and we examined the morphology and sex pheromones of the adults obtained. Consequently, the host plant ranges of the 7 Ostrinia spp. in Japan were clarified, and the sex pheromones of the 5 species O. scapulalis, O. zealis, O. zaguliaevi, O. palustralis and O. latipennis were identified in addition to that of the Asian corn borer O. furnacalis. The phylogenetic relationships of Japanese Ostrinia spp., with reference to the European corn borer O. nubilalis, are discussed based on these findings and results of molecular phylogenetic analyses. 相似文献

A pyraustine species of the genus Ostrinia Hübner collected at Shigakogen, central Honshu, Japan is described as new to science under the name of Ostrinia ovalipennis sp. nov. This species is morphologically similar to the Far Eastern knotweed borer, Ostrinia latipennis, but is distinguishable from O. latipennis in wing marking and male genitalia. Larvae of O. ovalipennis feed on the knotweed, Reynoutria sachalinensis (Polygonaceae), as do larvae of O. latipennis. In Shigakogen, adults of the two knotweed‐boring species co‐occur in the same season. Adults of O. ovalipennis were captured only in July, suggesting that this species is univoltine. The fact that O. ovalipennis shares several morphological and ecological features with O. latipennis suggests that the species is the closest relative of O. latipennis. 相似文献
