1958年笔者在福建莆田县哆后农业社,夏种后,飞虱、浮尘子为害早期晚稻十分严重。这期间,了解到县农场及其他一些农业社因7月间一度洪水淹没稻田而无此虫害。我们初步认为其原因除了食料断绝外,还由于卵的淹没。稻虫中,曾有防治黑椿象的浸水杀卵方法。在这些启示之下,我们试图用之于飞虱、浮尘子类的防治上,乃对当时发生最严重的白背飞虱Sogota furcifera Horvath进行一些观察和试验。 白背飞虱在福建一年大约发生5代,以第3代的成虫侵入晚稻田产卵,产卵盛期一般在7月下旬,这是第4代的卵;第5代卵盛其则在8月下旬。
1958 I was in Fujian Putian County Agricultural Cooperatives, after the summer species, planthopper, floating dust damage early rice is very serious. During this period, I learned that there was no pest damage at the county farms and some other agricultural cooperatives due to flooding of paddy fields once during the floods in July. We initially believe that in addition to the reasons for the food cut off, but also due to the inundation of eggs. In the pest insects, there was a method of controlling the soaking and watering of black toon. Based on these revelations, we tried to use it for the prevention and control of planthoppers and dusty sub-species. We made some observations and experiments on Sogota furcifera Horvath, the then-occurring Sipota furfur at that time. Whitebacked planthopper occurred in Fujian about five generations a year, with the third generation of adult invade rice in the late rice spawning, spawning peak is generally late in July, which is the fourth generation of eggs; In late August.
