The Colorado Beetle destroys which crop?
Colorado potato beetle were $13.3 million, representing 13.7% of the total value of the crop. The estimate of the cost implication of insecticides and crop losses per hectare is $138–368. Long-term increased cost to the Michigan potato industry caused by insecticide resistance in Colorado potato beetle was estimated at $0.9 to $1.4 million each year. The large scale use of insecticides in agricultural crops effectively controlled the pest until it became resistant to DDT in 1952 and dieldrin in 1958. Insecticides remain the main method of pest control on commercial farms. However, many chemicals are often unsuccessful when used against this pest because
Beetle kill in Colorado Beetle kill in Colorado The mountain pine beetle has killed large numbers of the lodgepole pine trees in the northern mountains of the US state of Colorado. The more recent outbreak of another bark beetle pest, the spruce beetle, is threatening higher-elevation forests of Engelmann spruce. Chemical prevention is effective but too costly for large-scale use. Dead trees increase the incidence of wildfires, and may contribute to climate change as they decay. Uses have been found for the dead wood including composting and in construction, and potentially to make biochar. Mountain pine beetles infest the lodgepole pine, which makes up
