Insect pheromones.
The evidence for intraspecies chemical communication in insects is reviewed, with emphasis on those studies where known organic compounds have been implicated. These signal-carrying chemicals are known as pheromones. There are two distinct types of pheromones, releasers and primers. Releaser pheromones initiate immediate behavioral responses in insects upon reception, while primer pheromones ca...
متن کاملThe Chemistry of Insect Hemolymph
alpha,alpha-Trehalose, a sugar previously regarded as a product characteristic of certain lower plants, has been identified as a major blood sugar of insects. Trehalose has been isolated in pure form from the blood of pupae of the silk moth, Telea polyphemus, and has been recognized chromatographically in all the insects examined, which comprise 10 species belonging to 5 different orders. Treha...
متن کاملPheromones - future techniques for insect control?
Four decades of pheromone research have provided the tools for environmentally safe control of insects through manipulation of male sexual behaviours. In Europe, disruption of mating by aerial dissemination of synthetic pheromones is used to control several economically important tortricids in orchards and vineyards on ca. 50 000 ha. In addition, attracticide lures have been developed for popul...
متن کاملPhotoperiodic regulation of insect and molluscan hormones.
The universal occurrence of photoperiodism in insects is due to convergentevolution. The neuroendocrine system, playing the central role in the photoperiodicresponse, gives diversified terminal expressions of adaptive significance. The responsecurve reflects the distributions of individual threshold photoperiods in three differentranges corresponding to the minimum number of dar...
