Abstract/Contents:"Studies during 1998 focused on four specific areas. These include: 1.) defining high risk areas for mole cricket infestations, 2.) determining the impact of soil moisture on oviposition and mole cricket development, 3.) investigating the effect of irrigation and specific environmental parameters on insecticide (both conventional and biological) performance, 4.) documenting the repellant response behavior of mole crickets to insecticide applications. Defining high risk areas for mole cricket infestations: The field portion of this study was completed in 1998 year as a Masters student research project. The results of this study are undergoing statistical analysis and the measurement of the soil texture is still underway in the laboratory. However, preliminary findings indicate there is some degree of separation between those sites most commonly inhabited by tawny and southern mole crickets. Determining the impact of soil moisture on oviposition and mole cricket development: Greenhouse studies to document the impact of soil moisture on oviposition have been completed by a Ph. D. candidate student. These studies conduced in a 7.5cm diameter by 15cm deep PVC cylinders filled with a uniform mixture of Kureb fine sand maintained at specific soil moistures conclusively demonstrated that crickets lay eggs more quickly and in higher numbers when soil moisture is maintained above 7% (Figure 1). This effect helps explain the annual varation we observe in mole cricket oviposition and egg hatch in the field, not only on a calendar basis, bt also based on degree day accumulations. Investigating the efect of irrigation and specific environmental parameters on insecticides (bot conventional and biological) performance: Soil dissipation studies in association with insecticide rate and irrigation regimen treatment plots indicate that irrigation may play less of a role in positioning the insecticide than it does in affecting mole cricket behavior. This area is schedled for additional investigation. Documenting the repellant response behavior of mole crickets to insecicide applications: Field studies have examined a wide range of insecticide rates, formulations, and soil moistre levels for short an long-term control effects. Similar studies have been conducted for biological control (Beauveria vassiana). Results indicate that reverse rate responses often occur with higher rates providing less control. This may be the result of avoidance behavior associated with higher rates."
