Abstract

Abstract Reticulitermes flavipes (Kollar) is best known throughout southwestern counties of Ontario, Canada, as an urban pest. Little is known, however, of the presence of this termite in nonurban settings in Ontario. In this study, we confirmed the existence of a population of R. flavipes on the shores of Lake Erie within Point Pelee National Park. A systematic trap survey conducted along the park's semi-vegetated west beach revealed several zones of termite activity. An analysis of trap response at one location indicated an association between termite activity and smaller sized, moderately decayed woody debris. Further, microsatellite DNA analysis suggested the presence of at least three genetically distinct colonies, each likely headed by multiple inbred reproductives. Together these data suggest that termite activity is linked to food quality, and that single colonies are potentially long-lived through multiple generations of inbreeding. Assuming it is derived from a population reported from Point Pelee in 1929, the study population is the oldest known eastern subterranean termite population in Ontario.

加拿大安大略省佩利角国家公园东部地下白蚁(等翅目:鼻白蚁科)的诱捕反应和遗传结构

摘要:黄斑网蝽(Reticulitermes flavipes, Kollar)是加拿大安大略省西南部各郡最著名的城市害虫。然而，人们对这种白蚁在安大略省非城市环境中的存在知之甚少。在这项研究中，我们证实了在Pelee角国家公园的伊利湖岸边存在一个种群。沿着公园半植被的西海滩进行的系统陷阱调查显示，白蚁活动的几个区域。对一个地点的捕集器反应的分析表明，白蚁的活动与较小的、中度腐烂的木质碎片有关。此外，微卫星DNA分析表明，至少存在三个遗传上不同的菌落，每个菌落可能由多个近亲繁殖的繁殖体领导。这些数据表明，白蚁的活动与食物质量有关，而且单个蚁群可能通过多代近亲繁殖而长寿。假设它来自于1929年在Pelee点报告的种群，研究种群是安大略省已知最古老的东部地下白蚁种群。
