RUI: A Genetic Analysis of the Production and Perception ofPheromonal Signals

许多昆虫的交配活动是由化学物质介导的， 视觉或听觉求爱信号。 昆虫的变化 求偶信号的变化与 信号的感知，因此，作为由一个 特定的物种会进化，信号的感知也会进化。 求偶信号的差异在不同的 种群是一个进化过程， 最终导致新物种的形成。 拟议 研究将提供一个遗传分析之间的耦合 化学求爱的产生和感知的变化 信号性信息素 这将由一个 果蝇两个不同品系的比较 黑腹菌 这项研究将揭示有关 生产与生产之间关系的遗传复杂性 对求爱信号的感知，以及 新物种形成过程中发生的遗传事件。 本研究结果也适用于昆虫 管理战略。 现代昆虫管理技术 通常会利用昆虫自身的信息素来破坏 交配活动或引诱昆虫进入陷阱。 这些 技术在短期内有效，但在长期内有效。 长期昆虫可能通过改变其体内的 产生和感知特定的信息素。 知识 关于生产变化的遗传基础， 信息素求爱信号的感知将有助于 确定对信息素技术的抗性是否可能 以及这种进化的速度。

Mating activity in many insects is mediated by chemical, visual or auditory courtship signals. Changes in insect courtship signals are closely associated with changes in the perception of the signals, so that as the signal produced by a particular species evolves, so does the perception of the signal. Divergence in courtship signals between members of different populations is one of the evolutionary processes that may eventually lead to the formation of new species. The proposed research will provide a genetic analysis of the coupling between changes in production and perception of chemical courtship signals, sex pheromone. This will be accomplished by a comparison of two divergent strains of the fruit fly, Drosophila melanogaster. This study will reveal new information about the genetic complexity of the relationship between production and perception of courtship signals, and about the complexity of genetic events that occur during the formation of new species. The results of this study will also be applicable to insect management strategies. Modern insect management techniques often involve the use of an insect's own pheromone to disrupt mating activities or to lure the insect to traps. These techniques are effective on a short term basis, but over the long term insects may evolve resistance through changes in the production and perception of specific pheromone. Knowledge about the genetic basis for changes in the production and perception of pheromonal courtship signals will help in determining whether resistance to pheromonal techniques is likely to evolve, and how rapidly such evolution might proceed.
