Revision of the North American Species ofLimonius(Coleoptera: Elateridae)

Efficacy of thiamethoxam and fipronil, applied alone and in combination, to control Limonius californicus and Hypnoidus bicolor (Coleoptera: Elateridae)

“…H. bicolor (no common name) is a smaller wireworm species with a 1–2 year life cycle, and it is distributed widely in the western, northeastern and central US states . The sugarbeet wireworm, L. californicus , is an average‐sized wireworm with a 4–11 year life cycle, and it is commonly found throughout the Pacific Northwest region of North America . Vernon et al .…”

“…Van Herk et al . observed that A. obscurus and L. canus spend significantly less time in contact with wheat seeds treated with a combination of thiamethoxam (Cruiser 350 FS) and a pyrethroid (Tefluthrin 20 CS) than with wheat seeds treated with each insecticide alone, resulting in lower mortality than when both insecticides were applied together . Intoxication by thiamethoxam might reduce wireworm feeding and the amount of fipronil ingested.…”

“…L. californicus and H. bicolor commonly infest wheat and barley crops in Montana, causing stand thinning and yield loss (Morales‐Rodriguez A, unpublished observations). H. bicolor (no common name) is a smaller wireworm species with a 1–2 year life cycle, and it is distributed widely in the western, northeastern and central US states . The sugarbeet wireworm, L. californicus , is an average‐sized wireworm with a 4–11 year life cycle, and it is commonly found throughout the Pacific Northwest region of North America .…”

DNA Barcoding to Improve the Species-Level Management of Wireworms (Coleoptera: Elateridae)

“…Field-collected adults were identiÞed to species using the appropriate literature (Brown 1935(Brown , 1936Becker 1956Becker , 1979Lane 1971;Stibick 1976Stibick , 1978Stibick , 1980Johnson 2002;Al Dhafer 2009). Locality and sequence information for all specimens was uploaded to BOLD and is available on the BOLD website (NCBI GenBank KF549671ÐKF549902).…”

Wireworms as Pests of Potato

“…Although little has been published from the Northeastern USA in recent years on wireworm species of economic importance, the most important species appear to be Agriotes mancus and Limonius agonus (listed as L. ectypus in older literature, but not the same as L. infuscatus, which is now called L. ectypus; Al Dhafer 2009) in Maine (Hawkins 1930, Hawkins et al 1958, New York State (MacLeod and Rawlins, 1935), Pennsylvania (Horsfall and Thomas 1926), and New Jersey (Pepper et al 1947). A. mancus is also listed as a key potato pest in Michigan, along with Melanotus spp.…”
