Abstract

Abstract The ceutorhynchine weevils Hadroplontus litura (F.) and Microplontus edentulus (Schultze) (Coleoptera: Curculionidae), are established in North America as biological control agents for Canada thistle, Cirsium arvense (L.) Scop., and scentless chamomile, Tripleurospermum perforatum (Mérat) M. Lainz (Asteraceae), respectively. In North America, both weeds occur sympatrically and in similar habitats as another ceutorhynchine, Ceutorhynchus obstrictus (Marsham) (cabbage seedpod weevil), an important pest of canola, Brassica napus L., and Brassica rapa L. (Brassicaceae). Ceutorhynchinae weevils released to control weeds in cultivated crops may serve as alternate hosts if agents released for biological control of C. obstrictus are not specific to that species. Parasitoids associated with M. edentulus and H. litura inflict similar levels of mortality on their hosts, yet a single species was associated with the latter host, whereas 13 species attacked the former. The stem-mining M. edentulus appears to be at some risk but not the root-crown feeding H. litura, should the parasitoids Trichomalus perfectus (Walker) and Mesopolobus morys (Walker) (Hymenoptera: Pteromalidae) be introduced as biological control agents of the silique-feeding C. obstrictus. These findings suggest that feeding niche may be an important criterion for developing a nontarget species test list for host-range testing of potential biological control agents.

北美两种典型杂草生物防治剂的欧洲外寄生蜂

摘要/ Abstract摘要:在北美地区已建立了斜纹硬象(Hadroplontus litura, F.)和齿纹小象(Microplontus edentulus, Schultze)作为加拿大蓟(Cirsium arvense, L.)的生物防治剂。吟游诗人。和无香洋甘菊，三胸精(三胸精)M. Lainz(菊科)。在北美，这两种杂草与另一种菜籽象鼻虫Ceutorhynchus obstrictus (Marsham)(白菜种子象鼻虫)是油菜、甘蓝型油菜和油菜科菜籽象鼻虫(Brassica napus L.， Brassica rapa L.， Brassicaceae)的重要害虫，它们是同地生长的，栖息地相似。如果释放的生物防治剂不是特定的，那么用于控制栽培作物杂草的Ceutorhynchinae象鼻虫可以作为替代寄主。与齿齿夜蛾和斜纹夜蛾相关的拟寄生物对其寄主的死亡率相似，但只有一种拟寄生物与后者相关，而13种拟寄生物攻击前者。如果引入拟寄生蜂完美毛蜂(Trichomalus perfectus)和morismesopolobus morys (Walker)(膜翅目:斑蜂科)作为生物防治剂，则采茎的齿状斑蜂(M. edentulus)有一定的风险，而采根冠的斜纹斑蜂(H. litura)则没有。这些结果表明，饲养生态位可能是制定潜在生物防治剂宿主范围测试的非靶种测试清单的重要标准。

期刊介绍： French translation follows/le français suit Published since 1868, this peer-reviewed bimonthly publication is the official journal of the Entomological Society of Canada. Available via the internet and with hardcopy distribution to 55 countries, its research papers and notes are relevant to entomologists and other biologists around the world. In addition to being a venue for topical reviews and forum discussion, The Canadian Entomologist publishes current research in all facets of entomology, including systematics and morphology, molecular and developmental biology, ecology and behaviour, biodiversity and evolution, insect management, entomological techniques, and other relevant subject areas. Contributions are published in English or French. Authors will not pay page charges, and will experience fast, high quality reviews of their papers.Publiée depuis 1868, cette publication bimestrielle avec comité de lecture est la revue officielle de la Société d’entomologie du Canada.
