通过随机抽样,比较了椰甲截脉姬小蜂Asecodes hispinarum Boucˇek林间种群与室内种群的雌雄比、出蜂量、未出蜂量、怀卵量的差异。t检验表明这些参数在2个种群间均存在显著的差异。野外种群和室内种群雌蜂比例分别占81.63%±2.54%和65.34%±1.80%,出蜂量分别是(25.13±1.17)头和(52.90±1.88)头。利用相关分析分析了寄主大小对寄生蜂性比的影响,表明寄主大小和寄生蜂雌雄比没有相关关系,不符合Charnov建立的寄生雌雄比与寄主大小关系的数学模型。
A random sample was used to compare the differences of the male and female ratio, the amount of bee-eaters, the amount of bee-eaters and the number of eggs laid between the Asecodes hispinarum Boucek forest and the indoor populations. The t test showed that these parameters were significantly different between the two populations. The proportion of female population in field and indoor populations accounted for 81.63% ± 2.54% and 65.34% ± 1.80%, respectively. The output of bees was (25.13 ± 1.17) and (52.90 ± 1.88), respectively. The relationship between host size and parasitoids was analyzed by correlation analysis, which showed that there was no correlation between the host size and the male-male ratio of parasitic wasps, which did not fit the mathematical model of the relationship between parasitic male-male ratio and host size established by Charnov.
