The wheat wireworm, Agriotes mancus Say, is a serious pest to Maine crops. An upland species of the genus Melanotus is second in importance. Certain cultural practices and immune crops have been found to be effective in checking wireworm infestations. Meadows and oat fields seem to be favorite breeding grounds for the wheat wireworm. Clover, buckwheat, and peas are resistant to the attacks of these insects and potatoes are very susceptible. Fertilizer is useful in strengthening plants to withstand wireworm attacks. Drainage is helpful in controlling the wheat wireworm and fall plowing is but partially effective.
