Abstract

A great deal of progress has been made over the last three decades in research on pheromone-mediated mating disruption technology for the oriental fruit moth, Grapholita molesta (Busck). Pheromones can interrupt normal orientation, and the most likely mechanism of pheromone disruption, competitive-attraction (false-plume following), invokes competition between point sources of pheromone formulation and females for males. This technology, performed by broadcasting pheromones into orchards to disrupt mate finding, has been successfully implemented in oriental fruit moth control. Reservoir-style dispensers made of polyethylene tubes, which release pheromone throughout the full growing season, are the current industry standard. Although reasonably effective, they require labor-intensive hand application. Recently, a new formulation, paraffin wax, which maximizes competition between point sources of synthetic pheromone and feral females for males, was shown to have high disruption performance. As this formulation is highly effective, inexpensive, and easy to produce, further study and development are advisable. Increased understanding of the principles of mating disruption will aid in the design of more effective dispensers. Continued research is needed to meet grower concerns with regard to risk, efficacy, and cost and to identify other semiochemicals that can be applied to this delivery system. Greater knowledge of the integration of different biological control methods is therefore essential.
性信息素介导的东方果蛾(鳞翅目:蛾科)交配中断技术综述与展望
近三十年来,信息素介导的东方果蛾(Grapholita molesta)交配中断技术研究取得了很大进展。信息素可以干扰正常的定向,信息素干扰最可能的机制,竞争性吸引(假羽跟随),引起信息素形成的点来源和雌性之间的竞争。该技术通过在果园中播撒信息素来干扰交配,已成功地应用于东方果蛾的防治。由聚乙烯管制成的水库式分配器,在整个生长季节释放信息素,是目前的行业标准。虽然它们相当有效,但需要大量的手工操作。最近,一种新的配方石蜡被证明具有很高的破坏性能,它可以最大限度地提高合成信息素的点源与野生雌性之间对雄性的竞争。该制剂具有高效、廉价、易生产等优点,值得进一步研究开发。增加对交配中断原理的理解将有助于设计更有效的分配器。需要继续进行研究,以满足种植者对风险、功效和成本的关注,并确定可应用于该输送系统的其他化学物质。因此,加强对综合不同生物防治方法的了解是必不可少的。
