“…In contrast, previous studies in open-air bioassays suggested that imidacloprid at high concentrations (> 1% a.i. in water or acetone) was slightly repellent to A. obscurus (van Herk et al 2008b). There were no significant differences in the proportion of moribund wireworms at the end of the observation period or dead at 56 DAE among the Admire and Gaucho treatments, suggesting that both formulations affected wireworm health similarly.…”

“…Furthermore, wireworms that become moribund after coming into contact with seeds treated with Poncho, Gaucho, Admire or Vitavax Dual may do so before ingesting enough insecticide to die. Since recovery from morbidity induced by these chemicals may continue for months (van Herk et al 2008a;Vernon et al 2008), wireworms returning to the same insecticidetreated plants that induced morbidity initially may not be affected once the plants are established (i.e. wheat and corn).…”

“…Recent toxicology work has shown that wireworms can recover from long-term (> 150 d) morbidity induced by dermal exposure to imidacloprid, clothianidin and thiamethoxam (van Herk et al 2008a;Vernon et al 2008). In addition, certain insecticides are suspected to have repellent as well as toxic effects on wireworms, including aldrin and lindane (Long and Lilly 1958;Toba et al 1988), terbufos (Belcher and Tenne 1987), and chlorpyrifos and fonofos (Horne and Horne 1991;Missionnier and Brunel 1979).…”

Larvae of the dusky wireworm, Agriotes obscurus, and the Pacific Coast wireworm, Limonius canus, were exposed to germinated, insecticide-treated wheat seeds in a soil-filled bioassay in 2005 and 2006. Position in the bioassay and contact and/or repellence behaviour towards the seeds were recorded every 5 min for 3 or 5 h. Wireworm health was recorded for 70 or 126 d after exposure. Seeds were treated with the fungicides Dividend XLRTA (difenoconazole, mefenoxam) or Raxil MD (tebuconazole, metalaxyl), and/or the insecticides Vitavax Dual (lindane), Poncho 600F (clothianidin), Cruiser 350FS (thiamethoxam), Admire 240FS (imidacloprid), Gaucho 480FL (imidacloprid), Tefluthrin 20CS (tefluthrin), or Tefluthrin-Cruiser combinations. Most wireworms (> 80%) came into contact with the seeds in all treatments. Wireworms generally remained in contact throughout the observation period in the control treatments (Dividend, Raxil, untreated seeds). Unless moribund, wireworms were repelled after brief (< 20 min) contact in all Tefluthrin treatments. Most wireworms recovered from contact-induced morbidity within 21 d and did not relapse, except L. canus exposed to Cruiser and some A. obscurus exposed to Gaucho and Admire. Wireworm mortality was low (< 50%) in all treatments except L. canus exposed to Cruiser at 15 and 30 g a.i. 100 kg-1 seed (60 and 75%, respectively). Mortality was significantly less important when L. canus larvae were exposed to Tefluthrin-Cruiser combinations than when exposed to Cruiser alone. We suggest that efficacy assessments of insecticides for wireworm control require direct observation of their behaviour and long-term post-exposure health assessments, and discuss the impact of repellence and/or morbidity elicited by insecticides on wireworm control in the field.

“…However, in a soil-filled bioassay wireworm mortality was low (< 50%) when being exposed to insecticide-treated wheat seeds (clothianidin, thiamethoxam, imidacloprid) (van Herk et al 2008a). In contrast, van Herk et al (2008b) observed neither a toxic nor a repellent effect of those particular neonicotinoids in a soil-less bioassay.…”

The aim of this paper is to review and interpret relevant work on population monitoring, damage prediction, agronomic strategies, and chemical as well as biological control of Agriotes wireworms in Europe.Wireworm populations and damages are on the rise globally. During the past decade, particularly research on the determination and distribution of Agriotes species has been brought forward. Summarising the recent click beetle surveys throughout Europe, the most widespread destructive species is A. lineatus, followed by A. obscurus and A. sputator. Developing species specific control methods seems to be advisable as Agriotes species differ greatly from one another concerning biology, ecology and crop preferences. Additionally, there are great regional differences in the distribution of species depending on factors such as climate and landscape parameters. Therefore, it is important to reliably determine the wireworm species as well as mapping their regional distribution.When selecting an insecticide, it is crucial to consider the need to provide both stand protection and wireworm reduction as certain insecticides act either as repellents or allow an extensive recovery of wireworms. However, the lack of efficacious insecticides and increasing wireworm pressure has intensified the need to evaluate alternative management strategies. Concerning wireworm control by agricultural methods, first encouraging data have been obtained in the fields of trap crops and crop rotation. However, their implementation in IPM strategies is still limited. Most promising seems the use of entomopathogenic fungi such as Beauveria bassiana and Metarhizium anisopliae, and their combination with either nematodes or insecticides. However, products for their commercial use still have to be developed.Currently, damage prediction and reliable control strategies are still challenging and need further investigation. Economic thresholds in susceptible crops need to be established particularly for the most destructive Agriotes species. Finally, the knowledge about the species specific biology and ecology still needs to be completed.
