Autor: Robert S. Vernon, W. G. van Herk, Stephen D. Gaimari, E. M. L. Cronin
Publikováno v: Journal of Applied Entomology. 139:154-157
Little is known about the natural enemies of wireworms (Coleoptera: Elateridae), but there are frequent anecdotal reports of (usually unnamed) stiletto fly larvae (Diptera: Therevidae) preying on various species. We observed larvae of Thereva nobilit

Blending of pheromone lures for two exotic European pest elaterid beetles
Autor: Robert S. Vernon, J. A. Tanaka, W. G. van Herk
Publikováno v: Journal of Pest Science. 87:619-627
Two exotic European click beetle species, Agriotes obscurus and Agriotes lineatus, were introduced into the lower Fraser valley of British Columbia over a century ago, and are now predominant pests of a number of arable crops. A semiochemical-based m

The molecular identification and genetic diversity of economically important wireworm species (Coleoptera: Elateridae) in Canada
Autor: Roderick P. Blackshaw, Robert S. Vernon, W. G. van Herk, Carly M. Benefer, Jonathan Ellis, Mairi E. Knight
Publikováno v: Journal of Pest Science. 86:19-27
Click beetle larvae (wireworms) are significant crop pests in Europe and North America. In Canada, there are ~30 economically important species which are morphologically difficult to identify, but for which sequence data are lacking. Accurate knowled

Autor: H. Ortiz Saavedra, Robert S. Vernon, J. H. Tolman, W. G. van Herk
Publikováno v: Journal of Economic Entomology. 101:375-383
Ten insecticides representing seven chemical groups were applied at various concentrations topically by using a Potter Spray Tower to evaluate their relative toxicities on the European wireworm Agriotes obscurus L. (Coleoptera: Elateridae). Wireworms

Repellency of a Wireworm, Agriotes obscurus (Coleoptera: Elateridae), on Exposure to Synthetic Insecticides in a Soil-Less Bioassay
Autor: Bernard D. Roitberg, W. G. van Herk, Robert S. Vernon
Publikováno v: Environmental Entomology. 37:534-545
A soil-less bioassay arena to test repellency of wireworms (A. obscurus) to insecticides and carrier solvents is described. The bioassay and variables measured distinguish between shorter-range (contact and/or volatile) and longer-range (volatile) re

Publikováno v: Entomologia Experimentalis et Applicata. 126:228-232
Late instars of the Pacific Coast wireworm, Limonius canus (LeConte) (Coleoptera: Elateridae), were exposed to wheat seeds treated with tefluthrin at 10 g active ingredient/100 kg wheat seed, for 2 min, at 10,15,20, and 25 °C. All wireworms were mor
