摘　　要：昆虫的生长发育离不开激素的调节。滞育作为昆虫特殊的发育状态,其特征是代谢活动显著降低,发育停滞。在滞育发育过程中,各类激素通常相互协调形成网络,发挥着重要的调节作用。在神经内分泌系统中,由神经细胞分泌的神经肽类激素通常作为上游调控激素,通过调节下游激素的合成和分泌从而影响昆虫的滞育发育;蜕皮激素和保幼激素作为下游激素参与到神经肽类激素的调控网络中。目前已克隆得到滞育激素-性信息素合成激活肽和促前胸腺激素的基因,并对二者在不同滞育型昆虫中的调节作用进行了深入研究。此外,激素受体的研究将为解释激素之间的相互作用提供重要依据;而通过滞育昆虫体内激素水平的调节将为有害昆虫生物防治提供新的方法。Insects growth and development are controlled by hormone. Diapause is a special development state. In this state, the significant characteristics are metabolism reducing and arrest of development. In the process of diapause development, a va riety of hormone tends to create a network by intercoordination. Diapause plays an important regulatory role in diapause devel opment. Insect neuroendocrine hormone is synthesized by neuroendocrine system and acts as upstream factor to affect insect di- apause by regulating the synthesis and release of the downstream hormone. The regulation function of diapause hormone-pher- omone biosynthesis activating neuropeptide and prothoracicotropic hormone in the different type of diapause, insects has been widely studied. Located at the downstream in the network of neuropeptide hormone, the hormones ecdysteroids and juvenile hormone also play important regulatory roles but less studied so far. In addition, the research of hormone receptors will pro vide an important basis to explain the interaction between hormones; and by adjusting the hormone levels in diapause insect which will provide a new method in the biological control of harmful insects.
