70年代以来,随着杂交水稻的推广,稻秆潜蝇(Chlorops′oryzae mats.)已急剧上升为丘陵和高、中海拔山区一季水稻主要害虫。以一代幼虫蛀食水稻秧苗心叶,致使叶片沿叶脉呈丝状破碎,破坏生长点,抑制水稻秧苗的生长;以二代幼虫钻入心叶,取食幼穗,最后留下半截或大半截,形成空秕。对于稻秆潜蝇的发生规律和为害习性近几年各地植保界相继进行了研究,作者于1985—1988年对其一、二代为害损失和防治指标进行了探讨,现将二代稻秆潜蝇被害率与卵株率相关性的研究简报于后。
Since the 1970s, with the popularization of hybrid rice, Chlorops’oryzae mats. Has risen sharply to the main pests of rice in the first season in the hilly and high altitude mid-elevation mountainous areas. A generation of larvae eats rice seedling heart leaves, resulting in filamentous rupture of the leaves along the veins, damaging growth points, inhibiting the growth of rice seedlings; second-generation larvae into the heart leaves, eating young ears, and finally leave half or half , Forming an empty 秕. For the occurrence of rice stem leaf miner and pest habits habits in recent years, plant protection circles have been studied in 1985 to 1988, the author of their first and second generations of damage and loss prevention and control indicators were discussed, now the second generation of rice straw lurking Research report on the correlation between flies damage rate and egg plant rate.
