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。
In this paper, we studied the pest occurrences and their predation effects on F. occidentalis in different planting patterns in the different planting patterns. The results showed that there were 2 peaks occurring each year in Kunming rose planting areas, which were 4 ~ May and August ~ September, of which the population was the highest in April-May. The population density of O. microphylla on the open-field rose-field was significantly higher than that of the greenhouse. The population density of S. aurantiaca on different varieties of rose was also The difference was that the population density of thrips was higher than that of the super breeds on the rose varieties. The functional response of S. occidentalis to F. occidentalis was in accordance with the Holling type II: Na = 1.2330 N / (1 + 0.02333 N). The maximum predation amount and the optimum seek density of adult S. occidentalis adults Respectively, 16.9 and 7.7 head.
