The effect of benserazid and 6-OHDA on the duration of the last larval instar and development of wings with intact corpora allata and following allatectomy on Acheta domestica L. was studied. 6-OHDA failed to alter the duration of the last larval instar in the nymphs with intact corpora allata but prolonged it in the allatectomized crickets. Introduction of 6-OHDA in the second phase of the last larval instar caused a deformation of the wings both in allatectomized and intact crickets. Injection of benserazid to the nymphs of the last larval instar prolonged the duration of this phase only in the presence of the corpora allata. The effect of benserazid can be connected to elimination of central inhibition of the corpora allata involving dopaminergic neurons of the brain.
研究了苄丝肼和6-羟基多巴胺对家蟋蟀末龄幼虫持续时间以及在咽侧体完整和咽侧体切除后翅膀发育的影响。6-羟基多巴胺未能改变咽侧体完整若虫的末龄幼虫持续时间，但延长了咽侧体切除蟋蟀的末龄幼虫持续时间。在末龄幼虫第二阶段引入6-羟基多巴胺会导致咽侧体切除和未切除的蟋蟀翅膀均发生变形。向末龄幼虫若虫注射苄丝肼仅在存在咽侧体时延长了该阶段的持续时间。苄丝肼的作用可能与消除涉及脑多巴胺能神经元的咽侧体中枢抑制有关。
