摘要

In social insects,recognition of nestmates from aliens is based on olfactory cues,and many studies have demonstrated that such cues are contained within the lipid layer covering the insect cuticle.These lipids are usually a complex mixture of tens of compounds in which aliphatic hydrocarbons are generally the major components.The experiments described here tested whether artificial changes in the cuticular profile through supplementation of naturally occurring alkanes and alkenes in honeybees affect the behaviour of nestmate guards.Compounds were applied to live foragers in microgram quantities and the bees returned to their hive entrance where the behaviour of the guard bees was observed.In this fashion we compared the effect of single alkenes with that of single alkanes;the effect of mixtures of alkenes versus that of mixtures of alkanes and the whole alkane fraction separated from the cuticular lipids versus the alkene fraction.With only one exception (the comparison between n-C_(19) and (2)9-C_(19)),in all the experiments bees treated with alkenes were attacked more intensively than bees treated with alkanes.This leads us to conclude that modification of the natural chemical profile with the two different classes of compounds has a different effect on acceptance and suggests that this may correspond to a differential importance in the recognition signature.
