colorado potato beetle adaptations

Beetles initially disperse by walking, so crop rotation and/or trenching can significantly reduce infestations. Abstract The author discusses current findings on food-plant adaptations and genetic variability among different geographical populations of the potato pest Leptinotarsa decemlineata (Say). How the solution works introduced against the Colorado Potato Beetle around 1910, and it look about 120 generations for the beetle to evolve resistance. This population is shown to be divided into two groups of local populations, in central and in peripheral parts of the study area, which differ in degree of intrapopulation diversity. The Colorado potato beetle is one of the most challenging agricultural pests to manage. To get a broader insight into the basis of larval adaptation to plant defenses, we created a "suppression subtractive hybridisation" library using cDNA from the gut of L. decemlineata larvae fed methyl jasmonate-induced or .
