Biological Control Effect and Occurrence Regularity of Leguminivora glycinivorella in Mudanjiang Hilly Midlevels
调查了牡丹江丘陵半山区大豆食心虫种群数量的动态变化及有关气象因素,并对化学防治与生物防治的效果进行比较.结果表明:2011年该区大豆食心虫始发期在7月下旬,终结期在8月末,持续时间约为35 d,高峰期出现在8月中下旬；随着温度的升高,食心虫数量有增高趋势,当温度达到一定程度后食心虫的数量波动幅度明显减小；化学防治与生物防治的单株粒重、虫粒数、虫食率、单株粒数在1％显著水平上达极显著差异,生物防治的单株粒数和单株粒重分别是化学防治的1.16和1.2…查看全部>>
Leguminivora glycinivorella seriously affect soybean production. We investigated the population change and related meteorological factors of Leguminwora glycinivorella in Mudanjiang hilly midlevels, also compared the prevention effects of chemical and biological control in this paper. Leguminwora glycinivorella started in late July and ended in the end of August in 2011, lasting for 35 days. Its peak time was in mid-to-late August. With the increase of tempe…查看全部>>
