Abstract:
... Fifty-nine sweetpotato cultivars, including 16 heirlooms, 11 near-heirlooms (developed in the 1960s and 1970s), 19 cultivars from the 1980s, and 13 modern varieties (since 1990), were evaluated for resistance to soil insects in field experiments during 2010–2011 at the U.S. Department of Agriculture-Agriculture Research Service, U.S. Vegetable Laboratory (USDA-ARS, USVL), Charleston, SC. These exp ...

2. Relative Susceptibility of Two Sweetpotato Varieties to Storage Root Damage by Sweetpotato Flea Beetle (Coleoptera: Chrysomelidae) and Wireworm (Coleoptera: Elateridae)

Chaetocnema confinis; Elateridae; Ipomoea batatas; growers; insects; planting; roots; soil; surveys; sweet potatoes
Abstract:
... The feeding of soil dwelling insects on storage roots is one of the most serious management issues faced by sweetpotato, Ipomoea batatas (L.) Lam. (Convolvulaceae), growers in the southern United States. Field studies were conducted to evaluate the relative susceptibility of two commonly grown sweetpotato varieties to sweetpotato flea beetle, Chaetocnema confinis Crotch (Coleoptera: Chrysomelidae) ...

Subject:
Chaetocnema confinis; Deloyala guttata; Ipomoea purpurea; Metriona bicolor; Spodoptera eridania; herbivores; induced resistance; insects; larvae; leaves
Abstract:
... A series of experiments indicate that induced changes occur in the foliage of the annual morning glory Ipomopea purpurea when subjected to prior damage. These changes reduce the growth rate, consumption rate, growth efficiency of larvae of the generalist lepidopteran Spodoptera eridania. They also alter the pattern of damage caused by specialist flea beetles, Chaetocnema confinis, and by generalis ...
