Along with the productive system and cropping system reform, the single harvest rice area expands. High yield of paddy rice dependes upon high planting density, high fertilizer aplication, and those creates advantageous enviroment for rice planthopper occurs. Temperature affects the main climatic factor for rice planthopper occurs in Anqing city.
