项目摘要

Population-biological studies on wing polymorphisms and related life history traits were conducted for stink bugs. The resuts obtained are summarized as follows.(1) There was a significantly positive genetic correlation between the sexes of the oriental chinch bug, Cavelerius saccharivorus, of the proportion macropterous or the mean relative wing length. However, the appearance rate of macropters tended to be much lower in males than in females, indicating that the wing polymorphism of males is not a simple result of the genetic correlation of wing morphology between the two sexes.(2) Reproduction and egg diapause of C.saccharivorus, in the subtropical winter season were investigated in relation to its wing polymorphism. Macropterous females collected from the southern part of Okinawa Is. in the autumn season delayd their oviposition and were less fecund early in the adult life period, but survived much longer than brachypterous females collected from the same locality. The total fecundity was not significantly different between wing morphs. The diapause of eggs laid by brachypters tended to be terminated more easily at a high temperature than that of eggs laid by macropters. This indicated that the eggs laid by macropters were more intense in their diapause than those laid by brachypters.(3) The environmental factors affecting wing length variation were investigated for a stink bug, Pyrrhocoris sibiricus. As a result, it was found that various environmental factors such high temperature, short-day length and moderate crowding tended to promote the production of longer hindwinged adults.

对椿象进行了翅膀多态性和相关生活史特征的群体生物学研究。主要研究结果如下：(1)东方金蝽Cavelerius saccharivorus的性别、大翅比例或平均相对翅长均存在显着的正相关遗传关系。但雄性大翅目昆虫的出现率往往远低于雌性，说明雄性翅膀多态性并不是两性翅膀形态遗传相关的简单结果。(2)对亚热带冬季的糖食C.saccharivorus的繁殖和卵滞育与其翅膀多态性的关系进行了研究。从冲绳岛南部采集的雌性大翅类。在秋季，它们的产卵延迟，并且在成虫生命早期的繁殖力较低，但比从同一地点收集的短翅雌性存活时间长得多。翅膀形态之间的总繁殖力没有显着差异。短翅目昆虫所产卵的滞育在高温下比大型翅目昆虫所产卵的滞育更容易终止。这表明大翅目昆虫的滞育期产卵强度比短翅目昆虫产卵的强度更大。(3)以西伯利亚臭虫Pyrrocoris sibiricus为研究对象,研究了影响翅长变化的环境因素。结果发现，高温、短日照和适度拥挤等各种环境因素往往会促进较长后翅成虫的产生。
