Expanding from remote areas of Mexico to a worldwide scale, the ten-striped insect, the Colorado potato beetle (CPB, Leptinotarsa decemlineata Say), has risen from being an innocuous beetle to a prominent global pest. A diverse life cycle, phenotypic plasticity, adaptation to adverse conditions, and capability to detoxify or tolerate toxins make this insect appear to be virtually "indestructibl...

The sustainable deployment of resistant crop varieties is a critical issue for the implementation of biotechnology in crop pest management. Feeding, biomass accumulation, and mortality were evaluated for susceptible, insecticide-resistant, and Bacillus thuringiensis (Bt) Cry 3A-selected Colorado potato beetle ( Leptinotarsa decemlineata Say) (Coleoptera, Chrysomelidae) larvae fed on: cultivated...

We evaluated the population dynamics of Colorado potato beetle in processing tomatoes and potatoes using immigration proÞles, density through time, rates of development and survivorship. We also evaluated the beetleÕs inßuence on yield of processing cultivars. Colorado potato beetle immigrated into both crops. The Þrst available crop had the earliest immigration event and higher immigrating adu...

Naive mated female cabbage looper moths, Trichoplusia ni Hübner, responded in a flight tunnel to potted potato plants ( Solanum tuberosum ). Percentages of moths attracted to uninjured potato plants, mechanically-damaged potato plants, and potato plants treated with regurgitant from larvae of the Colorado potato beetle, Leptinotarsa decemlineata Say, were similar, indicating no effect of plant ...

The ability of three cyanoacrylate glues to ensure a durable bond between the Colorado potato beetle, Leptinotarsa decemlineata (Say), the plum curculio, Conotrachelus nenuphar (Herbst), or the corn rootworms (Western Corn Rootworm, Diabrotica virgifera virgifera LeConte and Northern Corn Rootworm, Diabrotica longicornis Smith and Lawrence) and the harmonic radar tag without impact on behavior ...

The Colorado potato beetle, Leptinotarsa decemlineata (Say) (Coleoptera: Chrysomelidae) is the most important insect defoliator of potatoes that can completely destroy potato crops. Its current range covers about 16 million km in North America, Europe, and Asia and continues to expand. A complex and diverse life history, combined with an impressive ability to develop insecticide resistance, mak...

Wild relatives of potato offer a tremendous germplasm resource for breeders. Because the germplasm base of potato is so broad and diverse, we have undertaken a series of studies to determine whether we can predict the distribution of valuable genes in wild Solanum species based on taxonomic or biogeographic data. This is the third study in the series. Resistance to defoliation by Colorado potat...

The colorado potato beetle, Leptinotarsa decemlineata Say (Coleoptera: Chrysomelidae), is the leading insect pest of potato (Solanum tuberosum L.) in northern latitudes. Host plant resistance has the potential use in an integrated pest management program for control of colorado potato beetle. During the 1998 and 1999 seasons, field studies were conducted to compare natural (leptine glycoalkaloi...

the performance and flight behavior of the potato aphid macrosiphum euphorbiae was studied on the 'superior-bt' line transgenic for the cryiiia toxin of bacillus thuringien-sis (bt), resistant to the colorado potato beetle; and non transformed 'superior' line which served as control. mortality of the treated aphids was negligible and potato lines did not affect the development time of m. euphor...

The abundance of the Colorado potato beetle, Leptinotarsa decemlineata (Say), in organically grown potato did not change significantly in response to increasing rates of dehydrated poultry manure. However, peaks of abundance of larvae were shifted forward in time in response to the high rate of organic fertilizer. Tests using excised foliage showed that the shift was not caused by differential ...
