The list of pheromone controls on reproductive behavior can be extended female pheromones inhibit estrus in adult females and delay puberty in juvenile females, Lee-Boot effect male pheromones can block pregnancy, Bruce effect pheromones from dominant females can suppress reproduction in subordinate females and so on. Have a look at Wyatt s book for an abundance of examples.

We have also tried to attach filter papers with pheromone, control odors, and no odor, respectively, in the four comers of the laboratory or classroom near the ceiling. Moths can be released one by one in the center of the room, and their flight pattern monitored and scored. Dr. Stephen Teale initiated this experiment. 

Semiochemicals can be placed into two distinct classes Pheromones control intraspecific interactions. These semiochemicals provide information regarding a range of behaviours including mate selection, aggregation, dispersal (alarm pheromones), oviposition and food sources (trail pheromones). Allelochemicals control interspecific interactions such as host and non-host identification by primary colonizers (plant or animal) and whether a food source is already exploited through tritrophic interactions (signals indicating the presence of primary colonizers).

As discussed in Chapter 22, these pheromones control mating between haploid yeast cells of the opposite mating type, a or a. An a haploid cell secretes the a mating factor and has cell-surface receptors for the a factor an a cell secretes the a factor and has cell-surface receptors for the a factor (see Figure 22-13). Thus each type of cell recognizes the mating factor produced by the opposite type. Activation of the MAP kinase pathway by either the a or a receptors in-...

Since the survival of the beetle depends on overwhelming individual trees in the aggregation phase mediated by the pheromone, control strategy depends on reducing the intensity of these attacks. Two approaches have been used. 1. Large sticky traps baited with the pheromone have been distributed throughout the area of infestation to reduce the number of beetles available to attack trees (trap-out method). 2. The forest canopy has been permeated either with the pheromone or with an anti-attractant.
