非寄主植物与月季混栽对月季长管蚜种群的影响

采用非寄主植物孔雀草和韭菜与月季混栽,研究其对月季长管蚜种群的影响。分别将月季苗和孔雀草及韭菜按照3∶1、2∶1、1∶1、1∶2、1∶3的比例混栽,然后在开放和密闭两种生境下研究月季长管蚜的繁殖情况,通过计数蚜虫数量计算蚜虫增长率,比较不同混栽比例对蚜虫增长率的影响。试验结果表明：非寄主植物与月季混栽后,无论是在开放空间还是在密闭空间均影响了月季长管蚜的繁殖增长率。孔雀草与月季混栽,开放空间中对月季长管蚜繁殖增长率影响最大的是1∶3处理组,比对照组低351个百分点;密闭空间影响最大的是2∶1处理组,比对照组低502百分点。韭菜与月季混栽,开放空间中影响最大的是1∶3处理组,比对照组低433个百...

Bibliography:Non-host plant Tagetes patula L.and Allium tuberosum were mixed planted with Rosa hybrida,and at the same time,they brought the influence of Macrosiphum rosirvorum Zhang was investigated.The mixed planting proportion of Rosa hybrida and them was 3∶1,2∶1,1∶1,1∶2 and 1∶3,separately.Then the reproduction of the Macrosiphum rosirvorum Zhang was investigated under open and close conditions,and the increasing rate of the Macrosiphum rosirvorum Zhang was investigated under different mixed planting proporation.The experimentation indicated that once the mixed planting of non-host plant and Rosa hybrida,the increasing rate of the Macrosiphum rosirvorum Zhang was all affected both under the open and close conditions.When Tagetes patula L.was mixed planted with Rosa hybrida,the increasing rate of the Macrosiphum rosirvorum Zhang was affected mostly by the proportion 1∶3 under open conditions,which was less 351% than control group;while under close conditions the proportion 2∶1 was affected mostly,which was less 502% tha
