Abstract
通过在人工气候箱内饲养香蕉花蓟马，测定了14、18、22、26℃和30℃ 5个温度下香蕉花蓟马不同虫态的发育历期，分析了温度与香蕉花蓟马发育速率的关系，计算了其发育起点温度、有效积温及存活率。结果表明：香蕉花蓟马各虫态的发育历期随温度的升高而缩短，发育速率和温度之间有很大的相关性；香蕉花蓟马卵、一龄若虫、二龄若虫、预蛹、蛹及世代的发育起点温度分别为8.26、10.56、7.92、9.17、9.53、8.69℃ ，世代的有效积温为153.81d·℃。26℃下香蕉花蓟马的世代存活率最高，为63.16%；30℃下的存活率最低，为46.34%。;<em>Thrips hamaiiensis</em> (Morgan) was tested at five contest temperature (14,18,22,26℃ and30℃) in the laborary to investigate the development periods of their different development stages and calculate their development threshold temperature、effective accumulated temperature and survival rate. The results showed that the development period of different development stages shortened with the temperature increasement, the relationship between temperature and development speed of each life stage fitted with liner model. The development start temperature of Egg,NymphaeⅠ,NymphaeⅡ,Prepupa,Pupae and Whole generation was 8.26,10.56,7.92,9.17,9.53,8.69℃. The effective accumulative temperature of Whole generation was 153.81d·℃. The Generation survival rate at 25℃ was high, being 63.16%, while at 30℃was lower, only 46.34%.
