为做好水稻抗螟的鉴定工作,作者于近年探索了螟虫饲养及大量保存技术、接种虫态及抗性标准等内容。研究结果表明,在大田自然感虫条件下抗性表现在3级以上的品种,需要进行室内外多次人工接虫鉴定才能肯定抗性。以天然饲料饲养幼虫,低温保存卵、幼虫和蠕等方式解决接虫所需虫源。低温保卵又以前期和后期卵更耐低温。 In order to do a good job in the identification of rice stem borer, in recent years, the authors explored the stem borer feeding and a large number of preservation techniques, inoculation status and resistance standards and so on. The results showed that in the field of natural resistance to insects under the conditions of resistance in more than three varieties, the need for indoor and outdoor artificial insects to identify several times to confirm the resistance. Feeding larvae with natural feed, egg, larvae and creep preservation at low temperatures to solve the insect source required. Low-temperature pre-and post-ovulation eggs are more resistant to low temperature.
