The pheromones only directly attract males to the Metarhizium granules; females are infected only if they happen to randomly encounter the fungus granules. There are usually two generations per year in temperate climates of North America (Alvarez et al. In fields that are plowed deeply in the fall, wireworms will turn up during plowing. Wireworm control involves taking a soil sampling for wireworms or inspecting the soil after plowing in the fall. To date, field tests of entomopathogenic nematodes in wireworm infested fields show they do not effectively control wireworms. Rondon SI, Hane DC, Brown CR, Vales MI, Dogramaci M. 2009. You should try to utilize cultural methods for preventing tuberworms in potato crops such as irrigation to prevent soil cracks, planting uninfected seed pieces and deep seating of tubers before attempting to use an insecticide for controlling potato tuberworms. Sisay A, Ibrahim A. In addition, Kabaluk and his AAFC colleague, Wim van Herk, are evaluating whether the pheromone granules could be used to cause mating disruption in click beetles. The Andean or South American potatotuber moth, Symmetrischema tangolias (Gyen), is a pest of stored potatoes in the Andes. Rondon SI, Brown CR, Marchosky R. 2013. 1998. “We feel quite confident in the ability of our test products to kill wireworms and protect crops, but we need to formalize application methods and rates so that they are affordable to farmers. The potato: genetic resources and insect resistance, pp. 2005).Bio-pesticides and natural chemicals Bacillus thuringiensis (Bt) formulations have proved effective for potato tuber moth control in various parts of world (Alvarez et al. Typical damage results from larvae boring tunnels in tubers. Hornworms are easily identified and will feed on potato foliage. Pheromone traps that attract males have been effective for monitoring potato tuber moth populations. Either way, the potato tuberworm damage is a hole in the potato that is filled with, well, feces. Mature larvae pupate in the soil, developing into adults that will remain in the soil until the following spring, when they emerge, mate, and lay eggs. In Egypt, potato tuber moth has caused up to 100% losses to potato plants in fields as well as in storage (Ahmed et al. West of the Cascade Mountains, other species of wireworms, including Agriotes spp., are pests. Photograph by Silvia I. Rondon, Hermiston Agricultural Research and Extension Center, Oregon State University. “For wireworms, we apply the fungus with a substance that produces carbon dioxide. Management-chemical control: COMMERCIAL USE, The research includes field trials to develop effective ways to deliver the Metarhizium biopesticide to wireworms and click beetles.Photo: Todd Kabaluk/AAFC. Insert large carrots at least four inches … Soil insects, primarily wireworms and white grubs, can severely damage seed pieces and tubers. If there are eggs still around the roots themselves, you may be creating a nice warm environment where those eggs could hatch and infest your compost. As a result, there may be serious damage when irrigated crops are grown on sagebrush or dry wheat land. Trivedi TP, Rajagopal D. 1992. (31 Jan 2014). Severe infestations result in yield and quality losses during storage where previously infested tubers are stored with healthy potato tubers (Malakar and Tingey 2006, Rondon 2010). ), Insect Plant Interactions. Environmental Entomology 39:1037-1042. Damage is most likely to occur when the plants are young and the weather turns cold, causing seed germination to slow down. All infected plants should be removed from the garden and disposed of immediately upon identification. And while it may take some work to get rid of these soil pests, I’ll give you a list of options that will help you wipe them out. As the researchers had hoped, the resistant clones fared as well as — and sometimes better than — the insecticide-treated Russet Burbank potatoes. Commonly impacts corn, wheat and other cereal crops in addition to brassicas, root crops like carrots, potatoes, beets and sweet potatoes, climbing plants like beans and cowpeas, trailing plants like melons, and an assortment of others such as onions, lettuce, and strawberry. One generation per year, the life-cycle requiring 1-6 years to complete. (2009), and it was confirmed that tubers of the transgenic clone Spunta G2 were resistant to potato tuberworm damage. Wireworms or Carpet Beetle Larvae in the House. Wireworm feeding damage is easy to spot, says Rich Novy, a USDA-Agricultural Research Service (ARS) plant geneticist seeking to shore up America’s $3.3 billion potato crop. Saudi Journal of Biological Sciences 16:1-9. Spacing Collards When Planting a Square Foot Garden, How to Control Ants Around Your Raspberry Plants, University of California Integrated Pest Management Program: Wireworms, University of California IPM: Cucurbit Pests: Wireworms, University of California IPM: Tomato Pests: Wireworms, University of California IPM: Spinach Pests: Wireworms, University of Minnesota VegEdge: Wireworms, University of Florida IFAS Extension: Click Beetles / Wireworms, Virginia Cooperative Extension: Wireworm Pest Management in Potatoes, University of Georgia Department of Entomology: Wireworms, University of Minnesota Department of Entomology: AmTide Imidacloprid 2F Label. The mission of the NRSP-6 Potato Genebank is to facilitate improvements in the potato of the future by promoting the use of valuable exotic genes found in wild potato germplasm. They generally appear between May 25 and June 5. Roots and stems: Roots may show small blackened pits where feeding has occurred; plants may suddenly wilt and die. On crops such as maize, stems may be chewed and frayed just above the old seed. Rondon SI. Similar triangles may appear at the end of each lateral veinlet or the entire margin may roll upward as though scorched. These nematodes seek out and kill soil inhabiting potato tuberworm larvae without harming beneficial insects, such as ladybugs or earthworms. the same method of killing the insect. CropWatch: Potato Education Guide, UNL Extension. of sources of resistance to the potato tuber moth, Phthorimaea operculella (Zeller). Stored crop losses in potatoes ranging from 50% in Yemen and Peru, 86% in Tunisia, Algeria, and Turkey, 90% in Kenya, and 100% in India and the Philippines have been reported (Alvarez et al. The larval or immature stages cause major damage to seedlings and the underground portions of many annual crops.

Pan-water traps baited with the pheromone can be used for attracting and monitoring adult male populations.
