不同温度下浸水对褐飞虱生存、繁殖及其寄主的影响

This paper dealt with the effects of submerging rice plants on the hatchability,survival rate,feeding rate and fecundity of brown planthopper (BPH), Nilaparvata lugens St a °l ,at different temperatures.The physiological change of rice plants resulted from submerging was studied for revealing the impact of nutrient change of rice plant on BPH growth.The results showed that the egg hatchability of BPH collected from both Zhejiang and Guangxi Provinces was not significantly changed under the submergi...
