| 摘 要： | 本文研究了不同种植模式下月季上微小花蝽种群的发生特点及其对西花蓟马的捕食作用,结果表明:在昆明月季种植区,微小花蝽每年有2个发生高峰期,分别是4～5月份和8～9月份,其中,以4～5月份种群发生量最高;露地月季田块上的微小花蝽种群密度明显高于温室大棚;微小花蝽在不同月季品种上的种群密度也有所差异,月季艳粉品种上的蓟马种群密度高于超级品种。微小花蝽对西花蓟马的功能反应符合HollingⅡ型:Na=1.2330N/(1+0.02333N),1天内1头微小花蝽成虫对西花蓟马成虫的最大捕食量和最佳寻找密度分别为16.9头和7.7头。

| Abstract: | The population dynamics of Orius minutus and predation on Frankliniella occidentalis in different planting modes of China rose were conducted. The results as followed:there are two population peak of O. minutu in China rose planting areas of Kunming, that is in April-May and August-September. The population amount in April-May was significant higher than in August-September. The population densities of O. minutu in natural fields was higher than in the greenhouse. At same time, its densities in Yanfen breed... |
