南美斑潜蝇对蔬菜寄主的选择性

Host selectivity of the leafminer, Liriomyza huidobrenisis to vegetable varieties

摘要: 测定了南美斑潜蝇对豆科、葫芦科、茄科、十字花科、旋花科和伞形花科的20个蔬菜品种的选择性,结果表明,南美斑潜蝇对不同蔬菜作物的选择性从强到弱依次为豆科葫芦科茄科十字花科旋花科伞形花科。在豆科蔬菜中南美斑潜蝇最嗜食四季豆,其次是嗜食豇豆,对四棱豆的嗜好性较弱,对毛豆表现为非嗜好性。在葫芦科蔬菜中南美斑潜蝇最嗜食瓠瓜、黄瓜、丝瓜和南瓜,对苦瓜表现为非嗜好性;南美斑潜蝇对不同番茄品种的选择性也存在明显差异。

Abstract: The selectivity of Liriomyza huidobrenisis to 20 vegetable hosts from six families was studied in laboratory.The selectivity order of Liriomyza huidobrenisis to vegetable varieties was Leguminosae Cucurbitaceae Solanaceae CruiciferaeConvolvulanceaeUmbelliferae.Amond Leguminosae varieties, Liriomyza huidobrenisis preferred Phaseolus lunatus,Vigna sesquipedalis to Psophocarpus tetragonolobus, and exhibited nonpreference for Glycine max.Amond Cucurbitaceae varieties, Liriomyza huidobrenisis exhibited preference for Lagenaria vulgarisx, Cucumis sativus,.Luffa cylindrical, Cucurbita moschata, and nonpreference for Momordica charantia.There also showed significant difference in the selectivity of Liriomyza huidobrenisis to various tomato varieties.
