Predator diversity impacts herbivore abundance and behavior with cascading effects on the prevalence of a vector-borne plant pathogen
(University of Missouri--Columbia, 2013)
There is growing concern about the loss of biodiversity; particularly of organisms at higher trophic levels, such as predators, which face a disproportionately higher risk of extinction. As predator diversity declines there ...
Historical, landscape and resource influences on the coccinellid community in Missouri
(University of Missouri--Columbia, 2014)
The diversity and abundance of native lady beetle (Coccinellidae) species in North America is declining. This decline has been attributed to the introduction and establishment of exotic lady beetles, including Coccinella ...
Mechanisms of non-consumptive effects of parasitoid wasps on aphid populations : enhancing aphid suppression by increasing natural enemy and plant diversity /
(University of Missouri--Columbia, 2016)
Predators are typically evaluated for their potential effectiveness as natural biological control agents by examining traits related to their consumptive relationship with an herbivore. For example, voracious predators ...
Grasshopper and bee communities on Missouri prairies : comparing reconstructions and remnants
(University of Missouri--Columbia, 2018)
Tallgrass prairies once occupied a large swath of central North America, but now face the combined challenges of habitat loss and fragmentation. In Missouri, where less than 1% the historical prairie remains, prairies are ...
Habitat manipulations to enhance the abundance and diversity of pollinators visting helianthus annuus l.
(University of Missouri--Columbia, 2016)
Insect pollinators face many challenges with the development of modern agriculture. These challenges, such as reduction in habitat range and landscape fragmentation, may be overcome by diversifying the plant community. By ...
Partial characterization of Bt resistance and the bacteriome of western corn rootworm
(University of Missouri--Columbia, 2018)
Western corn rootworm (Diabrotica virgifera virgifera LeConte) and northern corn rootworm (Diabrotica barberi (Smith and Lawrence)) are major pests of maize in the USA. These pests have been managed with a variety of tactics ...
