Conditional signalling strategies: effects of ontogeny, social experience and social status on the pheromonal signal of male cockroaches
Article Abstract:
Changes in the pheromonal signals of male cockroaches are the result of social experience and interactions, and ontogenic changes. Males produce a three-component pheromone for attracting females that influences interactions between the two sexes. The levels of pheromone depend on the male sexual competence, male antagonistic behaviour and amount of attraction of the female. The levels of 2-methylthiazolidine and 4-ethyl-2-methoxyphenol are small in the glands of dominant males and not in those less dominant.

Lack of experimental evidence for pheromonal inhibition of reproduction among queens in the ant Leptothorax acervorum
Article Abstract:
A study exploring the possibility of pheremonal inhibition in egg-laying activity among ant queens sharing a colony was conducted. Results indicate no support for the hypothesis that there is pheromonal inhibition in egg-laying activity since there was neither a significant increase in egg-laying in the second phase of the experiment nor a significant decrease in egg-laying in the last phase of the experiment in the experimental ant-queen.

Odour conveys status on cockroaches
Article Abstract:
The sex pheromone of male cockroaches (Nauphoeta cinerea) is shown to determine rather than reflect status, through chemical manipulation of odour. The male-produced pheromone of N. cinerea to attract females, comprises heritable quantities of 3-hydroxy-2-butanone, 2-methylthiazolidine and 4-ethyl-2-meth-oxyphenol. The research showed than status depended on the specific pheromone manipulation.
