Suppression of Colorado Potato Beetle, Leptinotarsa decemlineata (Say), (Coleoptera: Chrysomelidae) Populations with Antifeedant Fungicides

Laboratory, small-field plot, and commercial-scale experiments were completed, using Connecticut, Rhode Island, and New York Colorado potato beetle, (CPB) Leptinotarsa decemlineata (Say), populations to determine if "antifeedant fungicides" might reduce the suitability of potato for CPB while simultaneously protecting potato from early and late blight. In the laboratory. fungicides formulated f...

Modeling Colonization of Overwintered Immigrant Leptinotarsa decemlineata (Coleoptera: Chrysomelidae)

Colonization of potato (Solanum tuberosum [L.]) Þelds by Colorado potato beetle, Leptinotarsa decemlineata (Say) (Coleoptera: Chrysomelidae), has often been recognized as a process that initially results in an edge-biased spatial pattern. We modeled this spatial process by measuring distance of immigration for individual overwintered adults.Distancewasmeasured to the nearest Þeld edge or to the...

Suppression of the Colorado Potato Beetle., Leptinotarsa decemlineata (Say) (Coleoptera: Chrysomelidae)., on Solanaceous Crops with a Copper-Based Fungicide

Environ.Entomol.13: 1010-1014 (1984) ABSTRACT Field experiments were carried out to determine if a copper-based fungicide known to deter feeding by the Colorado potato beetle, Leptinotarsa decemlineata (Say), in the laboratory, could suppress the growth of L. decemlineata populations in the field when used regularly for plant disease protection on tomatoes, potatoes, and eggplants. Larval densi...

Botanical insecticides for controlling agricultural pests: piperamides and the Colorado Potato Beetle Leptinotarsa decemlineata say (Coleoptera: Chrysomelidae).

The efficacy of extracts from two Piperaceae species, Piper nigrum L. and P. tuberculatum Jacq. were evaluated using larvae and adults of the Colorado Potato Beetle Leptinotarsa decemlineata (Say). Young larvae and neonates were the most susceptible; a 24-h LD(50) of 0.064% extract of P. tuberculatum was determined for 4-day-old larvae, while 0.05% extract of P. nigrum reduced larval survival u...
