Manipulation of fire ant density, Solenopsis spp., for short-term reduction of Diatraea saccharalis larval densities in Brazil
Provedor de dados: 63
Autores: Rossi,Marcelo Nogueira; Fowler,Harold Gordon.
The sugarcane borer, Diatraea saccharalis (Fabr.) is the main sugarcane pest in Brazil. In the State of São Paulo, the main active population control of D. saccharalis is by inundative releases of the exotic parasitoid, Cotesia flavipes (Cam.). However, the production of C. flavipes in sugar mills entails costs and few studies have evaluated the effects of native predators on sugarcane borer populations. Using a simple colony translocation method, we evaluated the effect of fire ants (Solenopsis spp.) on population densities of D. saccharalis and concurrently upon rates of parasitism by classical biological control agents in the São João sugar mill in the State of São Paulo, Brazil. The translocation technique proved to be feasible and economically...

Predaceous ant fauna in new sugarcane fields in the state of São Paulo, Brazil
Provedor de dados: 52
Autores: Rossi,Marcelo Nogueira; Fowler,Harold Gordon.
Predaceous ant fauna present in natural sugarcane field plantations in the state of São Paulo, Brazil, was evaluated by using sardine baits sampling technique. Three-month-old sugarcane plants were used for ant fauna estimation in two sugarcane mills, São João and Barra Mill. Twelve 30m X 30 m (900 m²) plots were previously delimited in each sugarcane mill for ant sampling. Ants were sampled in each plot by placing nine sardine baits in 12 mm X 75 mm plastic tubes. In the São João Mill, the predominant ant species observed was Solenopsis saevissima, followed by Dorymyrmex sp. 1, Pheidole sp. 2, and Crematogaster sp. 1. Considering only ant genus, Solenopsis, Pheidole, Dorymyrmex, and Crematogaster, were predominant. In the Barra Mill, the predominant ant...
