Ailanthus Altissima Aqueous Extract Deters Spodoptera Frugiperda Oviposition, Ryan L. Wagner, Jordan A. Card
Ailanthus Altissima Aqueous Extract Deters Spodoptera Frugiperda Oviposition, Ryan L. Wagner, Jordan A. Card
The Great Lakes Entomologist
Ailanthus altissima (Mill.) Swingle (Simaroubaceae), the tree of heaven, is a highly invasive tree species containing phytochemicals with a range of biological activities. Exposure to novel chemistry from invasive plant species may result in changes to established Lepidopteran behaviors, including feeding or oviposition. However, the impact of A. altissima chemistry on insect behavior has not been extensively explored. Therefore, A. altissima extract was tested for oviposition deterrence effects against Spodoptera frugiperda (Smith) (Noctuidae). Oviposition substrates were treated with water-soluble extractions of Zea mays (L), A. altissima, or a combination of both. Moths were then placed in chambers containing different …

The cranberry (Vaccinium macrocarpon Aiton) is an evergreen, trailing shrub native to North American peatlands. It is cultivated commercially in the US and Canada, with major production centers in Wisconsin, Massachusetts, New Jersey, Washington, Québec, and British Columbia. Despite the agricultural importance of cranberry in Wisconsin, relatively little is known of its arthropod associates, particularly the arachnid fauna. Here we report preliminary data on the insect and spider communities associated with wild and cultivated cranberries in Wisconsin. We then compare the insect and spider communities of wild cranberry systems to those of cultivated cranberries, indexed by region. Approximately 7,400 …
