Abstract

Mating and oviposition behavior can change the gene expression levels in insect antennae, especially for pheromone-binding protein (PBP) genes. In this study, we observed the development of the ovaries in the yellow peach moth, Conogethes punctiferalis (Guenée), from its early emergence to full maturity. Sex pheromones in the sex gland reached their highest quantity and influenced the expression of the PBP2 gene in male antennae. Furthermore, the expression of PBP genes was measured after mating and oviposition. The result showed that mating resulted in an increased expression of the PBP2 gene in male antennae, while the expression of the PBP1 gene increased in female antennae, indicating that PBP genes might play different functions in different sexes. Compared with females that had not mated, the PBP1 and PBP5 genes were up-regulated in female antennae after mating or oviposition. Altogether, the PBP genes were regulated by sex pheromone release, mating or oviposition, suggesting that these genes may play some critical roles in behaviors associated with reproduction.

PBP基因受棉铃虫卵巢发育、性信息素释放、交配和产卵行为的调控

交配和产卵行为可以改变昆虫触角中信息素结合蛋白(PBP)基因的表达水平。在本研究中，我们观察了黄桃蛾(Conogethes punctiferalis (guen e))的子房从初生到完全成熟的发育过程。性腺中的性信息素含量最高，影响雄性触角中ppb2基因的表达。在交配和产卵后检测PBP基因的表达。结果表明，交配导致雄性触须中PBP2基因表达增加，而雌性触须中PBP1基因表达增加，表明PBP基因在不同性别中可能发挥不同的功能。与未交配的雌性相比，交配或产卵后雌性触角中PBP1和PBP5基因表达上调。总之，PBP基因受性信息素释放、交配或产卵的调控，表明这些基因可能在与生殖相关的行为中起着关键作用。

期刊介绍： It is the aim of Chemoecology to promote and stimulate basic science in the field of chemical ecology by publishing research papers that integrate evolution and/or ecology and chemistry in an attempt to increase our understanding of the biological significance of natural products. Its scopes cover the evolutionary biology, mechanisms and chemistry of biotic interactions and the evolution and synthesis of the underlying natural products. Manuscripts on the evolution and ecology of trophic relationships, intra- and interspecific communication, competition, and other kinds of chemical communication in all types of organismic interactions will be considered suitable for publication. Ecological studies of trophic interactions will be considered also if they are based on the information of the transmission of natural products (e.g. fatty acids) through the food-chain. Chemoecology further publishes papers that relate to the evolution and ecology of interactions mediated by non-volatile compounds (e.g. adhesive secretions). Mechanistic approaches may include the identification, biosynthesis and metabolism of substances that carry information and the elucidation of receptor- and transduction systems using physiological, biochemical and molecular techniques. Papers describing the structure and functional morphology of organs involved in chemical communication will also be considered.
