松突圆蚧花角蚜小蜂的生物学

松突圆蚧花角蚜小蜂Cocvobius azumai Tachikawa是松突圆蚧Hemiberlesla pitysophila Takagi的重要寄生蜂,1987-1989年从日本引入我国广东省。对松突圆蚧花角蚜小蜂的形态、发育、繁殖、成虫寿命和取食寄主行为等生物学特征进行了观察。该蜂的雌性幼虫是松突圆蚧雌蚧的初级内寄生蜂,而雄性幼虫则是次级寄生蜂,重寄生在同种或它种膜翅目的老熟幼虫、预蛹和蛹上。雌雄两性的形态在所有发育阶段均不相同。交配过的雄蜂喜欢寄生产卵初期和盛期的雌成蚧,对巳寄生的寄主具有识别能力。在19.7℃一30.9℃变温条件下每头雌蜂平均产卵14.95粒,约60%的卵是在最初3天内产出。松突圆蚧花角蚜小蜂雌性蜂在21℃,24℃,27℃和30℃时从卵发育到成虫的平均历期分别为41.24,32.60,25.60和23.00天,发育起点温度10.1℃,有效积温448.3日度。该蜂在广东省一年发生。9-10代。

IMMATURE STAGES OF AUSTRALIAN ANTHOPHORINAE (HYMENOPTERA: APOIDEA)

i
Immature stages of two species in each of the two tribes, Anthophorini and Melectini, of Anthophorinae found in Australia were studied for the first time. The larvae and pupa of Amegilla (Amegilla) pulchra (Smith), the mature larva and pupa of Amegilla (Asarapoda) sp., the mature larva of Thyreus lugubris (Smith) and the pupa of Thyreus caeruleopunctatus (Blanchard) are described and the larvae are figured, and information is given on their behaviour and development.

川硬皮肿腿蜂染色体制备方法探讨

对川硬皮肿腿蜂Scleroderma sichuanensis Xiao(Hymenoptera:bethylidae Sclerderma)染色体制备方法进行了探讨,结果表明;以川硬皮肿腿蜂雌成虫卵巢为材料,经0.01%秋水仙素水溶液处理10min,蒸馏水低渗5min,用甲醇、冰醋酸(3∶1)固定液固定15min,Giemsa染液染色30min,可以获得形态良好、分散适中、着色清晰的染色体.     

REVISION OF CHINESE SPECIES OF HEMIPTARSENUS WESTWOOD (HYMENOPTERA: EULOPHIDAE) *

Abstract This paper deals with Chinese species of Hemiptarsenus Westwood, 1833. Totally five species are found in China. Among them, H. unguicellus (Zetterstedt), H. ornatus (Nees) and H. varicornis (Gi‐rault) were previously recorded, H. zilahisebessi Erdös is newly recorded in China and H. strigiscuta sp. n. is described as new. A tentative key to known species is given, and other three external species, H. fulvicollis Westwood, H. wailesellae Nowicky and H. waterhousii Westwood, are included in the key for comparison. The type specimen is deposited in the Zoological Museum, Institute of Zoology, Chinese Academy of Sciences.
