Enumerating lepidopteran species associated with maize as a first step in risk assessment in the USA.

摘要: Pest management can have substantial impacts on non-target species both within and outside the units being managed. Assessment of these is hampered by lack even most basic checklist present in systems. The maize agroecosytem particular interest because large area covered intensity widely varying forms pest management. In this study a database lepidopteran that occur agroecosystem United States was compiled. process initiated developing list plants using published sources first-hand knowledge “weed” experts. This plant associated with then cross-listed host feeding records sources. Finally, phenological profiles conservation rankings were added. Although our not exhaustive, we found 132 33 families maize, 229 21 feed plants. be starting point for assessment risk to Lepidoptera from chemical control, biological use transgenic Bt maize. significantly less imperiled, as measured their rankings, than whole all habitats. finding suggests rare or endangered are unlikely impacted Based likely impact individual species, future studies should focus potential ecological services provide.
