Evaluation of a suitable carrier plant for propagating Aphidius gifuensis Ashmead
In order to verify whether Gynura divavicata is a suitable host plants for propagating Aphidius gifuensis,we studied the developmental duration and fecundity of Myzus persicae on G.procumbens,Nicotiana tabacum,Solanum melongena and Raphanus sativus.Meanwhile,we got the innate capacity for increase (rm) and other major life table parameters,compared the effects of Myzus persicae which from different host plants on Aphidius gifuensis's development.The results showed that the developmental durations of M.persicae on 4 host plants were R.sativus (22.790 d) ＞ G.procumbens (22.225 d) ＞N.tabacum (22.005 d) ＞ S.melongena (18.924 d),there were no significant differences on the other 3 plants except S.melongena which was shortest.The reproduction of M.persicae on different hosts was R.sativus (63) ＞G.procumbens (52) ＞S.melongena (43) ＞N.tabacum (41);rm was S.melongena (0.283) ＞ R.sativus (0.278) ＞ G.procumbens (0.277) ＞ N.tabacum (0.255).Analysis of these results showed that under the same conditions,M.persicae prefer feeding S.melongena rather than feeding N.tabacum;the A.gifuensis's development were no significant differences between G.procumbens and S.melongena,Raphanus sativus.In summary,G.procumbens can be used as a suitable host plant to propagate large-scale M.persicae and A.gifuensis.
