| Abstract/Contents: | "Ormia depleta is a tachinid fly specialist on some species of Scapteriscus mole crickets. It is known from Brazil and Paraguay. A stock of this fly, captured at Piricicaba in subtropical Brazil (about 23° S) was brought to Florida in 1987 and cultured in quarantine. Beginning in 1988, progeny of these flies were released in all areas of Florida in attempt to establish a population - about 10,000 flies were released. A population became established in peninsular Florida and persists year-round to about 28° N, and seasonally (the fall of each year) in a marginal area extending to about 29° N. Subsequent releases in Georgia, North Carolina, and Alabama did not result in establishment of populations there. Although the established populations of the fly exhibit strong seasonality in Florida, with much greater numbers trapped in May-June and in November-December than at other times of year, the fly seems capable of breeding throughout the year. That is, there is no formant period (diapause) in winter. In the laboratory, adult flies need artificial nectar as a dietary items. Thus, it seems that the established stock of the fly, from subtropical Brazil, fares poorly in winter in northern Florida perhaps because it is not adapted to diapause during those months of the winter when plant nectars are in short supply (after freezes). But, the fly is known to exist in southern Brazil to 30° S. It is possible that flies at 30° S. are adapted to withstand colder winters by entering diapause. Therefore, they might be expected to survive in the southern USA at 30° N, and perhaps much farther north. The objective of this project is to obtain a stock of the fly from the extreme southern Brazil, bring it to quarantine in Gainesville, culture it, and provide stock to collaborating turfgrass entomologists in Alabama, Georgia, Louisiana, Mississippi, North Carolina, South Carolina, and Texas. In November 1998, two entomologists will travel to southern Brazil to spend almost 4 weeks collecting living Scapteriscus mole crickets as hosts for the fly. When scores of mole crickets have been assembled and maintained in containers in a laboratory in southern Brazil, flies will be trapped. Larvae of the flies will be reared on the mole crickets, and brought to the pupal stage. Fly pupae will be brought to quarantine in Florida for establishment of a laboratory culture. The timing of the visit (early summer)is based upon what is known about abundance and seasonality of Scapteriscus mole crickets and the fly in subtropical and temperate Brazil. Work in 1999 will focus on labor-intensive culturing of large numbers of the fly for distribution to other southern states." |
