摘要: 采用非自由选择法,在室内研究了南美斑潜蝇寄主选择性及其与植物叶片营养物质和叶绿素含量的关系.结果表明,南美斑潜蝇成虫对不同供试植物的选择性存在显著差异,选择性最强的为菜豆、茼蒿和西葫芦,最差的为番茄和甘蓝.相关分析表明,南美斑潜蝇成虫寄主选择性与叶片可溶性糖含量存在显著的正相关关系(R=0.5014,P=0.0174,F=6.717),而与叶片可溶性蛋白和叶绿素含量相关关系不显著.

Abstract: 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.
