Rainfastness of insecticides used to control Japanese beetle in blueberries.

Rainfastness and residual activity of insecticides to control Japanese beetle (Coleoptera: scarabaeidae) in Grapes.

Field-based bioassays and residue profile analysis were used to determine the relative toxicity, rainfastness, and field degradation over time of five insecticides from five insecticide classes on adult Japanese beetles, Popillia japonica Newman (Coleoptera: Scarabaeidae), in grapes, Vitis labrusca L. Bioassays assessed Japanese beetle condition as alive, knockdown, or immobile when exposed for...

Lethal and sublethal activities of imidacloprid contribute to control of adult Japanese beetle in blueberries.

Field-based bioassays and residue profile analysis were used to determine the relative importance of lethal and sublethal effects of imidacloprid on adult Japanese beetle, Popillia japonica Newman, in blueberries, Vaccinium corymbosum L. Field-based bioassays assessed adult mortality and knockdown, and fruit and leaf injury from Japanese beetles exposed to 4-h and 7-d field-aged residues of imi...

Survey of Japanese Beetle Management Practices in Michigan Highbush Blueberry Production

Michigan higbush blueberry (Vaccinium corymbosum) growers were surveyed during Winter 2003 to gather information on the extent of the pest status of japanese beetle (Popillia japonica, Coleoptera: Scarabaeidae) within this crop, and their responses to this pest management challenge. The survey was mailed to 215 highbush blueberry farms in southwestern, central, and southeastern Michigan. Ninety...

Evaluation of New Approaches for Management of Japanese Beetles in Highbush Blueberries

The Japanese beetle, Popillia japonica, can be a pest of highbush blueberries because of direct feeding on berries and leaves, and the risk of contaminating harvested fruit. To determine where beetles are most abundant and whether cultural controls have potential for use against P. japonica in blueberry, soil was sampled for grubs during 2001 and 2002 in and around fifteen blueberry fields. Den...
