本文报道以噻替派药膜接触成虫或用噻替派药液浸蛹均导致玉米螟雄性的显著不育。不仅可抑制亲代所产卵的孵化,而且能对子代产生一系列重要影响,子代卵也不能孵化,具有遗传不育作用。作者还研制出两种田间装置,可使药膜接触成虫不育方法与性引诱技术结合应用,从而导致玉米螟自然种群中的雄性不育。这种方法将比释放大量人工饲养并经过处理的不育个体具有一定的优越性。采用药液浸蛹不育方法,须在大量人工饲养害虫的基础上进行,但操作简便,处理后便于用水冲洗去除药剂残留,也有一定实用价值。此项研究力玉米螟化学不育的进一步探索提供了依据。
In this paper, we report that male sterility of maize borer was induced by exposure to adult worms with thiotepa or immersion of pupae with thiotepa. Not only can inhibit the parental hatch spawning, but also have a series of important impact on behalf of offspring, offspring eggs can not hatch, with the role of genetic sterility. The authors also developed two field devices that could be used in conjunction with the method of sexual contact with adult insects to induce male sterility in the natural population of the corn borer. This method will have some advantages over the release of a large number of sterile, treated and treated individuals. The use of liquid dip pupa infertility methods, to be carried out on the basis of a large number of artificial feeding pests, but easy to operate, easy to wash with water after treatment to remove pesticide residues, there are some practical value. This study provides a basis for further exploration of chemical sterility in corn borer.
