| 摘 要： | 为了明确种间竞争对西花蓟马和花蓟马种群数量增长的影响,研究了西花蓟马和花蓟马单种种群和两种蓟马混合种群在辣椒上的数量动态。结果表明:单种种群中花蓟马的增长速度大于西花蓟马;两种蓟马混合种群中,西花蓟马的种群增长速度大于花蓟马。说明,西花蓟马的种群增长受种间竞争影响较小,而花蓟马种群的增长受到的抑制作用较大,两种蓟马的种间竞争中,西花蓟马具有更强的竞争能力。

| Abstract: | The population dynamics of F.occidentalis and F.intonsa under the conditions of single species rearing and mixed species rearing on pepper were studied to explore the effects of interspecific competition on population of F.occidentalis and F.intonsa.The results showed that population growth of F.intonsa was larger than that of F. occidentalis in solitary population,and population growth of F.occidentalis was larger than that of F.intonsa in co-existing population.The population loss rate of F.occidentalis was lower at interspecific competition,while the population of F.intonsa was largely affected.The results indicated that F.occidentalis took the advantage at interspecies competition between two species of thrips. |
