摘  要:
调查了有机稻田褐飞虱种群与蜘蛛的发生动态。移栽后9 d褐飞虱发生量只有17头/百株,移栽后29 d增长到301头/百株,其中281头为1~2龄若虫。有机稻田中褐飞虱的发生量显著低于常规稻田,而有机稻田中蜘蛛类的数量显著高于常规稻田。

摘  要:
In this paper,the population dynamics of Nilaparvata lugens and spider in organic rice field were investigated.Nine days after transplanting,the population density of Nilaparvata lugens was only 17 heads per 100 plants;29 days after transplanting,the population density of this pest insect increased to 301 heads per 100 plants,among them there were 281 heads of 1~2 instar nymphae.The occurrence quantity of Nilaparvata lugens in organic rice field was significantly lower than that in conventional rice field,while the quantity of spider in organic rice field was markedly higher than that in conventional rice field.
