Vegetation manipulation impact on predator and prey populations in Louisiana sugarcane ecosystems


, : Vegetation manipulation impact on predator and prey populations in Louisiana sugarcane ecosystems. Journal of Economic Entomology, 786: 1409-1414

Plot tests in sugarcane fields in south-eastern Louisiana in 1982-84 demonstrated the beneficial impact of ground vegetation on the enhancement of predation. The abundance and diversity of both ground- and foliage-associated predators and prey were higher in weedy than in weed-free habitats. The formicid Solenopsis invicta, a major predator of the pyralid pest Diatraea saccharalis, was more abundant in weedy (there being 17 mounds/ha) than in weed-free (5 mounds/ha) habitats.
