REGISTERED AND EXPERIMENTAL FOLIAR INSECTICIDES TO CONTROL COLORADO POTATO BEETLE AND POTATO LEAFHOPPER IN POTATO, 2013

Glycoalkaloid responses of potato to Colorado potato beetle defoliation.

Two experiments were conducted to measure the glycoalkaloid concentrations of potato tubers in response to Colorado potato beetle and manual defoliation. For plants defoliated by Colorado potato beetles, there was a significantly greater production of glycoalkaloids than in control plants and manually defoliated plants for both skin and inner tissue of tubers in experiment 1. In experiment 1, t...

Comparing Host Plant Resistance, Engineered Resistance, and Insecticide Treatment for Control of Colorado Potato Beetle and Potato Leafhopper in Potatoes

The Colorado potato beetle, Leptinotarsa decemlineata (Say) Order Coleoptera and the potato leafhopper, Empoasca fabae (Harris) Order Homoptera, are the major insect pests of potato in eastern North America. In two years of field trials, we compared the effectiveness of three pest management options for the control of Colorado potato beetle and potato leafhopper: natural host plant resistance (...

Habitat manipulation in potato affects Colorado potato beetle dispersal

The Colorado potato beetle [Leptinotarsa decemlineata (Say); Coleoptera: Chrysomelidae] is a significant pest of potatoes in North America and Eurasia and can cause severe defoliation and yield loss (Ferro 1985; Weber and Ferro 1994b). Managing the Colorado potato beetle with intensive pesticide applications has led to resistant populations (Forgash 1985; Ioannidis et al. 1991; Stewart et al. 1...

Response of potato aphid (Homoptera: Aphididae) to synthetic potato-derived Colorado potato beetle (Coleoptera: Chrysomelidae) attractant and natural potato odor.

A recently synthesized kairomone blend, based on the volatiles produced by potato (Solanum spp.) plants, has been demonstrated to be attractive to both adult and larval stages of the Colorado potato beetle, Leptinotarsa decemlineata (Say) (Coleoptera: Chrysomelidae). It was subsequently formulated in a viscous inert carrier for field applications and showed potential for aggregating beetles in ...
