Abstract

Abstract Thrips (Thysanoptera: Thripidae) communities in agroecosystems are poorly known, particularly in Québec, Canada, where thrips can cause damage in strawberry crops. The phenology of anthophagous thrips and their use of cultivated and wildflower resources were monitored in strawberry agroecosystems, encompassing strawberry (Rosaceae) fields and adjacent uncultivated margins, on Orléans Island, Québec, Canada. A community comprised of 11 thrips species was described, dominated during the whole season by pest species Frankliniella tritici and F. intonsa , which is a first mention in Eastern Canada. Surprisingly, the major strawberry pest F. occidentalis was absent in our samples. Thrips species richness and abundance on wildflowers varied, with few flowering plant species supporting a majority of the community. Sampling sites and local wildflower presence influenced the thrips species assemblage observed on strawberry crops. Such a high thrips diversity was unexpected in this agroecosystem. The identified associations between pest thrips and wildflower species will be useful to develop better control programmes in strawberry crops.

“永远的草莓田”:加拿大quacimbec草莓农业生态系统中花栖蓟马群落及其空间相互作用，首次提到害虫Frankliniella intonsa (Trybom)

摘要在农业生态系统中，人们对蓟马(蓟翅目:Thripidae)群落知之甚少，特别是在加拿大的quamesbec，那里的蓟马会对草莓作物造成损害。在加拿大quimenbec省orlsamans岛的草莓农业生态系统中，对草莓(蔷花科)田及其邻近的未开垦边缘进行了食蓟马物候及其对栽培和野花资源的利用监测。结果表明，该地区共有11种蓟马，在整个季节均以小麦富兰克林蓟马(Frankliniella tritici)和滇马蓟马(F. intonsa)为主要害虫，在加拿大东部地区尚属首次报道。令人惊讶的是，我们的样品中没有主要的草莓害虫西白蝇。蓟马的物种丰富度和对野花的丰富度存在差异，少数开花植物支持大部分群落。采样地点和当地野花的存在对草莓作物上观察到的蓟马种类组合有影响。如此高的蓟马多样性在该农业生态系统中是出乎意料的。已确定的害虫蓟马与野花物种之间的联系将有助于制定更好的草莓作物控制计划。
