Sex attractants in frass from bark beetles.
Shortly after Kangas et al. (1) reported that a-terpineol was the major component of a primary host attractant for Blastophagus piniperda L., Silverstein, Rodin, and Wood (2) revealed the identity of three other terpene alcohols that play a role in the orientation of bark beetles. However, Silverstein et al. concluded, from laboratory bioassay, that a mixture of the three terpene alcohols they ...
متن کاملSex pheromones: abolition of specificity in hybrid bark beetles.
Specificity of sex pheromones maintains breeding isolation among three closely related species of spruce-infesting Ips. Hybrids produced in the laboratory were intermediate to the parent species in both attractiveness and response. Pheromones and pheromone receptor types in the hybrids are probably mixtures of those of the parent species.
متن کاملSex attractants in primates.
The role of olfactory sexual attractants in the sex behavior of primates is discussed. These olfactory cues can prompt mounting, masturbation, and ejaculation, increase grooming behavior, and reduce aggressive behavior. In rhesus monkeys, the addition of phenylpropanoic and parahydroxyphenylpropanoic acids to a synthetic acid mixture has been shown to enhance the effectiveness of the syntheti...
متن کاملInteractions of Root Disease and Bark Beetles
Associations between root diseases and bark beetles (Scolytidae) constitute some of the most serious pest complexes affecting forests in North America and elsewhere. The interactive functioning of these pests derives from the following relationships: 1) root diseases predispose trees to bark beetle infestation by lowering resistance, and perhaps increasing attractiveness, of trees to the attack...
متن کاملBehavioral mechanisms involved in reducing competition in bark beetles
Bark beetles feed and reproduce in the phloem/cambium tissue of trees where severe competition between individuals of the same and different species significantly reduces their reproductive success. In this coevolutionary setting, individuals that can avoid competition whenever possible by means of genetically controlled behavioral mechanisms are naturally selected. Avoidance of intraspecific a...
