摘要
通过研究黄花美人蕉、黄花槐、凤尾兰和夹竹桃4种花卉寄主对西花蓟马生长发育、存活率的影响,及西花蓟马对4种寄主的颜色选择、自由选择行为,探讨了西花蓟马对4种寄主的偏好性。结果表明,西花蓟马在4种寄主上的生长发育速率为黄花美人蕉>黄花槐>凤尾兰>夹竹桃,存活率为凤尾兰>黄花美人蕉>黄花槐>夹竹桃。西花蓟马对寄主颜色的选择趋性为黄花美人蕉=黄花槐>凤尾兰>夹竹桃,对寄主自由选择的趋性为黄花槐>黄花美人蕉>凤尾兰>夹竹桃。综上,西花蓟马对黄花美人蕉和黄花槐的偏好性强于凤尾兰和夹竹桃。
The host preference of Frankliniella occidentalis was explored by researching the effect of different hosts on the development and survival of the insects, as well as the colour choice and the free choice behaviors of insects to the hosts. The results showed that the preference level decreased in Cannaceae indica,Sophora xanthantha,Yucca gloriosa and Nerium indicum,according to the development period of F. occidentalis on the four hosts. F. occidentalis showed different preference according to the survival rate versus development period, the highest was on Y. gloriosa, followed by C. indica and S. xanthantha, and the lowest was on N. indicum. The preference level decreased in C. indica, S. xanthantha,Y. gloriosa and N. indicum, according to the colour choice of F. occidentalis to the hosts, while there was no significant difference between C. indica and S. xanthantha. Similar to the colour choice,the preference level decreased in S. xanthantha,C. indica,Y. gloriosa and N. indicum,according to the free choice of F. occidentalis to the hosts. From these results,we could conclude that F. occidentalis prefers C. indica and S. xanthantha to Y. gloriosa and N. indicum.
