Control of melon thrips, Thrips palmi Karny, by a soil treatment of carbam sodium solution after the harvesting of greenhouse cucumber

Abstract

The effects of a soil treatment of carbam sodium solution on the density of melon thrips, Thrips palmi Karny, was investigated after the harvesting of greenhouse cucumber. In the treatment plot, the cucumber was covered with a film, and the carbam sodium solution was sprayed on the soil surface. The number of adult thrips caught by blue sticky traps and emergence traps was lower in the treatment plot than in the film plot and the control plot. These results suggest that a soil treatment of carbam sodium can effectively control the density of thrips.
