摘要
通过对棘跳虫生活习性及发生规律的观察研究和防治试验表明,棘跳虫在绥宁县1a发生6～7代,世代重叠;以成虫或高龄若虫越冬;发生适宜温度18～28℃,低于15℃或高于33℃不利发生,相对湿度在80%～90%时有利发生;一至三代发生量大,为害百合严重;选择对口农药,采用生态农业综合治理技术可控制其为害。
The living habitats,occurring rule s of Onychiurus sp.and its control techniques were s tudied.Results showed that Onychiurus sp.reproduced 6～7generations annually and overlap generations existe d as well.Onychiurus sp.overwintered by imagoes or higher instars of larva.S uitable temperature range for its development was 18～22℃,the temperatu re above 33℃or below 15℃wasn' t favorable for its incidences,rela tive humidity between 80%and 90%is i ts favorite humidity range.Onychiurus sp.could be controlled by properly s praying pesticide and the implement ation of IPM strategies.
