Wireworms are primary pests of potatoes in Canada. Presently, the highly toxic organophosphate phorate (i.e., Thimet 20G) is the only effective insecticide in use in Canada. As such, there is an urgent need for novel alternative treatments that provi

Several Agriotes click beetle species are important pests of vegetables and field crops. Monitoring for beetles is generally done with pheromone-baited traps maintained in permanent locations. Since dispersal is mostly by walking, such traps may depl

We evaluated the relative efficacy of six pheromone-baited traps used in trapping Agriotes obscurus (L.) click beetles (Coleoptera: Elateridae): original Yatlor Traps, Yatlor Funnel Traps, Vernon Beetle Traps, Unitraps, Baited Pitfall Traps, and Vern

In North America, monitoring for Agriotes spp. click beetles typically has been done using Vernon beetle traps baited with bubble cap sex pheromone lures. This trap and lure are no longer produced commercially and a new trap, the Vernon pitfall trap,

Following the deregistration of lindane, several neonicotinoid insecticides have been registered as seed treatments for controlling wireworms in cereal crops. Unlike lindane, which did both, neonicotinoids provide crop protection but do not reduce wi

We present findings of a general survey of pest wireworms in Alberta, Saskatchewan, and Manitoba conducted from 2004 to 2019; the first such survey of the Canadian Prairie provinces since that published by Glen et al. (1943). Samples were collected f

Wireworms are important economic pests that attack the seeds and roots of numerous vegetable and field crops worldwide. A 5-yr study was conducted in the main agricultural regions of the province of Quebec (Canada), to identify and characterize the w
