Biodiversity and dynamics of planthoppers and their natural enemies in rice fields with different nitrogen regimes

, : Biodiversity and dynamics of planthoppers and their natural enemies in rice fields with different nitrogen regimes. Rice Science 13(3): 218-226

The effects of N fertilizer rates (200, 100 and 0 kg N/ha) on the diversity of plant hoppers and their natural enemies in rice (IR 64) fields at the International Rice Research Institute in the Philippines. The biodiversity of arthropods, and the population dynamics of planthoppers, egg parasitoids under Homoptera trapped in rice plants with eggs of brown planthoppers (BPH; Nilaparvata lugens), and web spiders in the rice canopy were analysed at various rice growth stages.
