Mole Cricket IPM Guide for Florida

A pest management strategy using a systematic approach in which pest populations are monitored to determine if and when control methods are required. Integrated pest management (IPM) uses biological, chemical, physical, cultural and/or genetic control methods in order to minimize pesticide use, reduce production costs, and protect the environment. [NALT]

Integrated pest management is the careful consideration of all available pest control techniques and subsequent integration of appropriate measures that discourage the development of pest populations and keep pesticides and other interventions to levels that are economically justified and reduce or minimize risks to human and animal health and/or the environment. [AGROVOC]

Mole crickets can become serious pests of turfgrasses, pastures, and vegetable seedlings. Three non-native species of mole crickets occur in Florida, including the tawny, southern, and shortwinged mole crickets. Adults are about 1 1/2 inch long, light brown, and have enlarged forelegs that they use to dig in soil. The forelegs have large blade-like projections, called dactyls, and the number and arrangement of dactyls, as well as the pronotum pattern (area behind the head), are used to identify different species. Nymphs look like adults, but their wings (wing pads) are not completely developed and they can't reproduce. Shortwinged mole cricket adults have short wings and cannot fly. Mole crickets damage turfgrass in several ways. Nymphs and adults feed on grass roots and blades at night after rain or irrigation, during warm weather. Their tunneling near the soil surface dislodges plants or causes them to dry out. Small mounds of soil are also pushed up by late summer. More than 20 feet of tunneling per night can occur. Tunneling and root-feeding reduce turfgrass density and create patches of bare soil.

The Department of Entomology and Nematology maintains tripartite priorities consistent with the mandate given to full-service landgrant universities and associated experiment stations: Research, Extension, and Academics. These programs are facilitated with state funding, extramural contract and grant funding, donations and gifts, and the collaborative efforts of cooperating agencies and institutions. The Department has coordinated faculty efforts and strengths into what could be considered major thrust areas for the Department. These areas of emphasis include: Behavior, Ecology, and Systematics; Biological Control; Medical, Veterinary and Urban Entomology; Nematology; Pest Management; and Physiology, Biochemistry, and Genetics.
