近年来,自治区苜蓿面积不断扩大,因而苜蓿籽象(虫甲)(Tychius medicaginis Bris)所造成的损失,更值得重视。据一九六二年在下野地四场调查,苜蓿种籽被害率高达50％。为害苜蓿籽的象(虫甲)种类很多,常见的有苜蓿籽象(虫甲),草木樨籽象(虫甲),以苜蓿籽象(虫甲)为北疆准噶尔盆地玛纳斯河地区的优势种。 苜蓿籽象(虫甲)成虫为害苜蓿茎、叶、花、蕾,幼虫则为害种籽。一九六三年在石河子地区调查,种籽被害率高者达30％,一般为10％,严重地影响苜蓿的生产和发展。现将对此虫的初步观察,报导于后。
In recent years, Autonomous Region, alfalfa area continues to expand, so the loss of alfalfa seeds (insects) (Tychius medicaginis Bris), more worthy of attention. According to the four surveys conducted in the field in 1962, alfalfa seeds have been victimized by as much as 50%. The main types of alfalfa seeds are insects (insects), common alfalfa seeds (insects), herbaceous seeds (insects), alfalfa seeds (insects) as the Manas River area of northern Junggar Basin The dominant species. Alfalfa seeds (insect) adult damage alfalfa stems, leaves, flowers, buds, larvae are harmful seeds. In 1963, a survey of Shihezi region showed that the highest rate of seed-killing was 30%, usually 10%, seriously affecting the production and development of alfalfa. Now the initial observation of this worm, reported later.
