小腹茧蜂亚科的雄外生殖器及族级单元系统发育的研究

对分布在东洋区和古北区的小腹茧蜂亚科 (膜翅目: 茧蜂科)21个属的67个种及外群折脉茧蜂属 (膜翅目: 茧蜂科) 2个种的雄外生殖器的5个性状进行了比较研究。在形态学研究的基础上,通过选用头部、胸部和腹部(包括雌雄外生殖器的性状) 等34个性状,运用支序分析的方法探讨了分布在东洋区和古北区的小腹茧蜂亚科21个属以及它们所属的族间的系统发育关系,并对Mason (1981) 的分类系统进行了重新评价。雄外生殖器和支序分析基本上证实并恢复了由Mason (1981) 确定的2个主要分支,即绒茧蜂族Apantelini+小腹茧蜂族Microgastrini和拱茧蜂族Fornicini+盘绒茧蜂族Cotesiini+侧沟茧蜂族MicroplitinI。绒茧蜂族Apantelini、拱茧蜂族Fornicini和侧沟茧蜂族Microplitini为单系群也被支持,但小腹茧蜂族Microgastrini和盘绒茧蜂族Cotesiini是否为单系群尚难于在树形图中体现,而且族内各属间的分支关系有变动。因此,尽管Mason的族级分类单元有一些欠缺,但仍是可信、实用的,不同意Walker等 (1990) 认为不应再使用Mason分族系统的观点。

The male genitalia of Oxyartes lamellatus - phasmatodeans do have complex phallic organs (Insecta: Phasmatodea)

A detailed study of the exoskeleton and musculature of the phallic organ of Oxyartes lamellatus (Kirby, 1904) (Phasmatodea: Necrosciinae) is here presented - the first study of this kind for Phasmatodea. The asymmetrical phallic organ shows a highly complicated morphology, with several sclerites and many formative structural elements, of which a sclerotised bulb in the ejaculatory duct wall and a long flagellum arising from near it are among the most conspicuous. Four extrinsic and 20 intrinsic phallic muscles were found; many of these are quite compact bundles or sheets, while a few others are diffuse groups of fibres. Phallic morphology in Oxyartes is compared with the literature data on male genitalia in other Phasmatodea, but this is limited by the superficial treatment of phallic organs in the few relevant previous contributions. Yet, phallic organs appear as a useful new character system for phylogenetic reconstruction and species distinction in Phasmatodea. Comparison with phallic organs in other ‘orthopteroid’ insects shows that these organs are too different among orders as to allow for sound homologisation of phallic substructures. Consideration of development of phallic organs does not help in this aspect. There is no evidence of phasmatodean phallic organs being pedomorphic.     

Cold hardiness of Habrobracon hebetor (Say) (Hymenoptera: Braconidae), a parasitoid of pyralid moths

The ectoparasitoid Habrobracon hebetor (Say) attacks stored-product infesting pyralid moths that are able to overwinter under extremely cold conditions. The extent to which H. hebetor can withstand these conditions is not known, but has important implications for the ability of H. hebetor to provide long-term suppression of these pests in temperate climates. We investigated basic cold hardiness aspects of a mutant eye-color strain of H. hebetor. Feeding larvae and adults of H. hebetor had supercooling points (SCPs) at temperatures higher than those of eggs and pupae. Mean SCPs of females and males were equivalent, as were those of naked and silk-encased pupae. Feeding on honey prior to being subjected to low temperatures significantly increased the SCP of adult females by approximately 8 degrees C. Mortality of pupae and adults increased significantly whenever the temperature dropped below the mean SCP, indicating that H. hebetor does not tolerate freezing. For pupae and adults exposed to -12 and -5 degrees C, the hourly mortality rate increased with time of exposure. Pupae and adults exposed to -12 degrees C for different time intervals showed high mortality after only 1d of exposure. At -5 degrees C, none survived 12d of exposure. A better understanding of how well this parasitoid tolerates low temperatures will be useful in evaluating its potential as a biological control agent of stored-product moths in temperate regions.     

Musculature of the male genitalia in Rivellia (Diptera: Platystomatidae)

The musculature of male genitalia was studied hitherto only in two species of Tephritidae, one species of Platystomatidae, one species of Pallopteridae, and three species of Ulidiidae of the superfamily Tephritoidea. The split of the hypandrium from one structure into three (the hypandrium and two lateral sclerites) is traced. The hypandrial origin of the lateral sclerites of the hypandrial complex is shown based on the localization of muscle attachment sites. The subepandrial origin of the inner lobes of the surstyli is also confirmed.
