| Popis: | PHEROMONES function by transmitting information from a sending to a receiving organism by chemical means. In a classic paper, Bossert and Wilson classified the effects of such information transfer into releasing and priming1. Releaser pheromones evoke an immediate overt behavioural effect, whereas primer pheromones activate the chemoreceptor in such a way as to alter the physiology of the receiving organism1,2. In general, studies involving the isolation identification of pheromones have concentrated on releasers such as sex attractants, alarm pheromones, trail pheromones and aggregation pheromones3. The advantage of using releaser pheromones in such studies is that the behavioural effects can be observed even in a single individual of the appropriate age, sex and species. This makes the development of a relatively simple and rapid bioassay a straightforward process. So far the important exception to the use of releaser pheromones has been the work of Butler et al. showing that 9-ketodecenoic acid inhibits ovarian development in worker bees4. This substance, however, was first identified as the sex attractant of the queen bee and later shown to have a primer effect. We describe here a bioassay for a substance with an effect which does not fit easily into either the releaser or primer category. |
