近几年稻绿蝽在我区为害严重。为此我们对其进行了调查研究和防治试验,现将结果报道如下:一、为害损失调查1987年稻绿蝽在双晚穗期虫口密度较大,据9月下旬水稻灌浆期调查,百蔸虫口密度10~257.5头,一般百蔸虫口密度27.5~75头。稻绿蝽主要以成、若虫在水稻灌浆期用刺吸式口器吸取谷粒汁液,造成谷粒空瘪。以灌浆期虫口密度最大,随着水稻逐渐成熟,虫口密度逐渐下降。据调查,水稻穗期受稻绿蝽不同
In recent years, green rice stink bug in our area seriously harmed. To this end we carried out research and prevention and control of the test, the results are reported as follows: First, the loss of damage survey 1987 green rice stink bug in double-headed earwax population density, according to late September survey of rice filling period, Insect population density of 10 ~ 257.5, the general population of insects mouth density 27.5 ~ 75. Rice stink bug mainly to as, nymphs in the rice filling stage suction piercing mouthparts to absorb grain juice, resulting in empty grain deflated. At the filling stage, the density of insect population was the largest. As the rice matured, the density of insect population gradually decreased. According to the survey, paddy rice different stages of rice bugs
