一九七八年我们参加了在江苏农科院和广东农科院主持下的全国褐稻虱联合测报网。在院内、外各兄弟单位的大力支持下,在一九七七年工作的基础上对褐稻蝨在长沙东郊的发虫经过继续进行了系统观察,从4月22日起至11月上旬在我院教学农场及附近大队进行了田间系统调查;200支光测灯诱虫;田间长翅型雌成虫卵巢发育进度系统解剖,衡山南岳(海拔1,268米)装设高空捕虫网,固定专人逐日收集,定期取回学院在双解镜下鉴定所获虫种。通过这两年的初步观察与分析,对长沙地区褐稻蝨田间发生经过和各代成虫的来龙去脉,有了较明确的了解,现将七八年的情况整理如下。
In 1978, we participated in the joint national network of brown planthopper test under the auspices of Jiangsu Academy of Agricultural Sciences and Guangdong Academy of Agricultural Sciences. With the vigorous support of the brothers and sisters inside and outside the hospital and on the basis of their work in 1977, the systematic observation was carried out on the development of brown planthopper in the eastern suburbs of Changsha from April 22 to early November In our hospital teaching farms and nearby brigade conducted a field system investigation; 200 light trap light trap insects; field long-winged adult ovary ovarian development systematic anatomy, Hengshan Nanyue (1,268 meters above sea level) installed high-altitude insect net, fixed by day Collect and periodically retrieve the species identified by the institute under biomicroscopy. Through the preliminary observation and analysis in the past two years, we have got a clearer understanding of the ins and outs of brown planthopper in the field in Changsha and the generations of adults. The situation in 1978 is summarized as follows.
