南美斑潜蝇寄主选择性与植物营养物质及叶绿素含量的关系

The laboratory study with no free choice means showed that the host preference of Liriomyza huidobrensis(Blanchard)adult differed significantly with test plants.Phaseolus vulgaris,Chrysanthemum coronarium and Cucurbita pepo were the most preferred,while Lycopersicum esculentum and Brassica oleracea were the least.Correlative analysis indicated that the host preference of L.huidobrensis adult had a significant positive correlation with the content of soluble sugar,but less correlation with soluble protein and chlorophyll contents in host foliage.
