Abstract

Cuticular hydrocarbons serve as cues for nestmate recognition in Lasius ants, and the compound 3-MeC31 signals the queen’s fertility, acting as a queen pheromone to regulate reproductive division of labour. Juvenile hormone (JH) has been reported to inhibit reproduction in Lasius niger queens during vitellogenesis and oogenesis by modulating vitellogenin expression. The hormonal pleiotropy of juvenile hormone (JH) has been shown to affect fertility and the production of fertility cues in other social insects. The purpose of this study is to review the effect of JH on queen reproduction by looking at egg-laying rates in the early phases of nest foundation, as well as changes in chemical profiles and 3-MeC31 expression. Methoprene treatment led to an increase of 3-MeC31 production compared to precocene-treated queens; however, there was no increase in egg laying. Furthermore, chemical profiles of males and winged queens differed distinctly from the treated dealate queens.

幼虫激素对黑鳞鲃雌蚁化学特征和繁殖力的影响

角质碳氢化合物是 Lasius 蚂蚁识别巢友的线索，化合物 3-MeC31 是蚁后生育能力的信号，作为蚁后信息素调节生殖分工。据报道，幼年激素（JH）通过调节卵黄原蛋白的表达，在卵黄发生和卵子发生过程中抑制黑蚁蚁后的繁殖。在其他社会性昆虫中，幼体激素（JH）的荷尔蒙多效性已被证明会影响繁殖力和繁殖线索的产生。本研究的目的是通过观察筑巢初期的产卵率以及化学特征和 3-MeC31 表达的变化，回顾 JH 对蜂后繁殖的影响。与早熟烯处理的蜂王相比，甲氧苄啶处理导致3-MeC31产量增加；但产卵量没有增加。此外，雄蜂和有翅蜂王的化学特征与经处理的雌蜂有明显不同。

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.
