“…Pest management of wireworms does not require the prophylactic use of neonicotinoids and in cases where pest densities are high, alternatives to insecticides exist. Some approaches are still being tested, such as mass trapping of adult wireworms with light traps [104], crop rotations with brown mustard or buckwheat [105], attraction to insecticide-treated wheat grown between untreated potato rows [106]; they represent alternative control measures that are under development in Canada. Other methods, such as trap crops using pea and lentil [107] or the use of entomopathogenic fungi such as Metarhizium anisopliae [108,109,110] could be tested on a large scale against wireworms.…”

Agricultural soil pests, including wireworms (Coleoptera: Elateridae), are managed primarily with pesticides applied directly to seeds before sowing. Seeds coated with neonicotinoids have been used widely in Quebec (Canada) for several years. To assess the agronomic and economic value of neonicotinoid seed treatments in soybeans and corn in Quebec, trials were conducted from 2012 to 2016 in 84 fields across seven regions in Quebec. We evaluated the effect of neonicotinoid seed treatments on soil pest densities, crop damage and yield. The results showed that 92.6% of corn fields and 69.0% of soybean fields had less than 1 wireworm per bait trap. However, no significant differences in plant stand or yield were observed between treated and untreated corn or soybeans during the study. This study shows that neonicotinoid seed treatments in field crops in Quebec are useful in less than 5% of cases, given the very low level of pest-associated pressure and damage, and that they should not be used prophylactically. Integrated pest management (IPM) strategies need to be developed for soil insect pests to offer effective alternative solutions to producers.

“…However, with wireworms, the presence of higher numbers of larvae caught in bait traps buried in empty plots indicates that closely planted trap crop might work better for distracting wireworms away from the main crop. For wireworm management, attract‐and‐kill (A&K) strategies can be used by luring the wireworms to an attractant, and killing them with an associated insecticidal agent (El‐Sayed, Suckling, Byers, Jang, & Wearing, ; Gut, Stelinski, Thomson, & Miller, ; Vernon, Herk, Clodius, & Tolman, ). Recently, this method was found to be effective in managing A. obscurus and Melanotus spp.…”

“…Recently, this method was found to be effective in managing A. obscurus and Melanotus spp. in potato crops in Canada, where wheat seeds treated with fipronil and/or thiamethoxam were planted in‐furrow alongside untreated mother tubers of potatoes (Vernon et al, ). Association of the high number of wireworms in plots with zero wheat seeds, but sown with trap crops, could work as an A&K strategy if the trap crop seeds were pesticide‐treated.…”

Assessing the performance of pea and lentil at different seeding densities as trap crops for the management of wireworms in spring wheat

Wireworms, the larvae of click beetles (Elateridae), are difficult to manage due to their habitats and behaviour. Wireworms pose a major threat to the wheat crop in the north‐western USA. Seed treatment with neonicotinoids, biological control management and some cultural controls are recommended to manage these pests. Trap cropping is an emerging way to manage wireworms. In strawberry and potato crops, trap cropping has been found effective at attracting wireworms away from the principal crop. An earlier study in the Golden Triangle area of Montana found that pea and lentil could be effective trap crops for managing wireworms in spring wheat. In the present study, experiments were conducted at two locations. The effectiveness of peas and lentils as trap crops with wheat at different seeding densities was assessed [pea at 0, 4, 8, 16 seeds/sq.ft. or 0, 43, 86, 172 seeds/sq.m.; lentil at 0, 6, 12, 18 OR 0, 65, 130, 194 seeds/sq.m.; both with wheat at 0, 11, 22, or 28 seeds/sq.ft. or 0, 120, 230, 300 seeds/sq.m.] in a randomized design where all three crops were intercropped. Both trap crops were found to be effective in protecting wheat at standard seeding rates of 8 seeds/sq.ft. for pea and 12 seeds/sq.ft. for lentils. At these seeding rates, higher numbers of wireworms were found to be attracted to the trap crop, resulting in higher yield (7%–10%) of the associated spring wheat plant stands at 22 seeds/sq.ft. To develop an effective trap crop strategy, the pea–wheat and lentil–wheat spatial patterns that are possible need to be assessed in further field trials. Proper design and evaluation of the cost–benefit ratio of pea and lentil as trap crops are likely to produce good results for wheat crops in Montana.

“…2,000‐fold less water than usual spray application (Hiltpold et al., ). The innovative combination of suitable formulations and an A&K approach has the potential to enhance biological control (Brandl et al., ; Hiltpold et al., ) and reduce insecticide use (Schumann et al., ; Vernon, van Herk, Clodius, & Tolman, ) in soil pest control. Much knowledge on the WCR immature chemical ecology is required to improve this approach and contribute to a more sustainable pest management.…”

In the darkness of the soil matrix, the larva of the western corn rootworm (WCR) Diabrotica virgifera virgifera LeConte relies on chemical cues to locate and accept its host plant roots. For almost 40 years, entomologists and chemical ecologists have tackled the challenge of isolating and identifying active chemical compounds emitted by host plant roots (most of the research has been conducted on maize Zea mays L.) and used by the foraging insect pest larvae. A number of molecules of interest have been documented but have so far only been implemented with little success in the current arms race to manage WCR (and soil‐dwelling pests). An in‐depth understanding of the mechanisms underlying the insect foraging behaviour is certainly critical to the development of highly effective and sustainable pest control strategies. This contribution reviews the progress and highlights the gaps in our current knowledge on the chemical ecology of WCR larvae. An individual‐based model of the larval behaviour in response to root volatiles has been developed based on data from the literature. It also proposes avenues (tested or theoretical) to eventually implement this knowledge in integrated pest management of this major maize pest, a critical approach as WCR has evolved resistance to several control strategies.
