2.
The influences of interspecies competition between Coccinella septempunctata and Leis axyridis were studied under the condition of single rearing and mixed rearing,and Lotka-Volterra equation was used to simulate the competition when more preys and less preys provided for the two ladybirds.
通过单种群与混合种群饲养,研究了猎物密度对七星瓢虫Coccinella septempunctata和异色瓢虫Leis axyridis种间竞争影响,并用Lotka-Volterra种间竞争模型对两种瓢虫在猎物相对充足与不足条件下的种间竞争进行模拟,结果表明:猎物充足,两种瓢虫的种群增长呈线性增长趋势;猎物不足时,单独饲养时,两种瓢虫的种群增长趋势呈Logistic曲线,混合饲养时异色瓢虫的种群增长呈上升趋势,七星瓢虫趋于下降。
