多年来,我们在永安、沙县进行三化螟测报的过程中,常发现在枯心苗(团)或白穗团周围有不少的稻株受三化螟危害之后,不表现出枯心或白穗,似乎“无螟害”的迹象,但只要仔细考察,便可见到一个至数个的蛀入孔;当稻株处于腊熟阶段被三化螟幼虫转株蛀入后,不久剑叶则先退黄(而邻近的健株却仍正常),好象早衰等特点,如再剖开稻株一看,茎内常有一定的虫量(1～3头/株),我们暂称此种稻株为“隐害株”(下同)。为了探索其危害情况和提高螟虫的测报技术与质量,
Over the years, we reported that in the Yong’an and Shaxian Counties of the Yellow Stem Borer, we found that after the rice plants were damaged by the three stem borers, White spike, it seems “no stem borer” signs, but as long as the careful examination, we can see one or several holes into the borehole; when the rice plants in waxy stage by the stem borer larvae rotten plants after decay, Then the first yellow (and adjacent healthy plants are still normal), such as premature aging and other characteristics, such as re-open the rice a look, the stem often have some insects (1 ~ 3 / plant), we tentatively This rice plant is a “hidden strain” (the same below). In order to explore its harm situation and improve the measurement technology and quality of stem borers,
