西花蓟马对不同蔬菜寄主的选择性研究

Selectivity of Frankliniella occidentalis (Pergande) on different host vegetables

  • 摘要: 采用植株自由选择法和叶碟法研究了西花蓟马对不同蔬菜寄主及同一寄主不同部位叶片的选择性。结果表明, 西花蓟马成虫对7 种不同蔬菜寄主的选择趋性为西葫芦>茄子砧木>黄瓜>茄子>菜豆>辣椒>番茄,产卵选择性为西葫芦>茄子>菜豆>黄瓜>辣椒>茄子砧木=番茄。西花蓟马喜欢在辣椒、茄子和西葫芦相对幼嫩的上中部叶片产卵, 喜欢在番茄叶片中下部成熟叶片产卵, 而其在菜豆中部叶片的产卵量明显高于上部嫩叶和下部老叶。西花蓟马成虫在辣椒、茄子和菜豆上倾向于在嫩叶取食, 在番茄上喜欢在中下部叶片取食, 在西葫芦的中部叶片发现较多的西花蓟马成虫。

     

    Abstract: The selectivity of F. occidentalis on different host vegetables and vegetable leaves were studied using a pot experiment on 7 vegetables and a leaf disc test with selected vegetable leaves. The results showed that the preference of adult F. occidentalis for seven host vegetables was summer squash>eggplant rootstock>cucumber>eggplant>bean>chili pepper>tomato. The rank order of oviposition preference of F. occidentalis was summer squash>eggplant>bean>cucumber>chili pepper>eggplant rootstock or tomato. There were more larvae on apical or middle younger leaves of chili pepper, eggplant and summer squash than on basal leaves. However, more larvae hatched on middle and basal older leaves than on apical leaves of tomato. The amount of oviposition on middle leaves was significantly greater than on other parts of bean. Adult F. occidentalis preferred feeding on younger leaves of chili pepper, eggplant and bean. F. occidentalis liked feeding on middle and basal leaves of tomato, and preferred middle leaves of summer squash.
