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。
Insect growth and development can not be separated from the regulation of hormones. Diapause as a special insect developmental state, characterized by significantly reduced metabolic activity, developmental stagnation. In the process of diapause development, all kinds of hormones usually coordinate with each other to form a network and play an important regulatory role. In the neuroendocrine system, neuropeptide hormones secreted by nerve cells usually act as upstream regulatory hormones, which influence the diapause development of insects by regulating the synthesis and secretion of downstream hormones; ecdysone and juvenile hormones are involved as downstream hormones in neuropeptides Hormone regulation of the network. At present, we have cloned the gene of the diastolic hormone-sex pheromone synthesis activating peptide and the pro-thymidine hormone, and studied the regulation of the two in different diapause insects. In addition, hormone receptor research will provide an important basis for explaining the interaction between hormones; and the regulation of hormonal levels in diapause insects will provide a new method for biological control of harmful insects.
