Abstract
The southern potato wireworm, Conoderus falli Lane, and the corn wireworm, Melanotus communis (Gyllenhal), are important vegetable crop pests in organic soils of the Everglades. Sweet corn is one of the crops most susceptible to damage by either of these wireworms. The southern potato wireworm has developed resistance to chlorinated hydrocarbon insecticides in Florida (Workman 1963) and in South Carolina (Reid and Cuthbert 1956). However, it is usually adequately controlled by any one of several phosphatic insecticides. The corn wireworm has been the more difficult species to control in the organic soils of the Everglades. Soil insect control is usually more difficult in organic soils than in mineral soils. Wireworm control research in the Everglades was intensified in 1961 after many growers reported inadequate control with recommended practices. Several insecticides were compared. Insecticide baits were evaluated in applications made before planting sweet corn and in applications made after corn plants had emerged from the soil.
