[目的]研究美洲斑潜蝇对几种花卉的偏嗜性.[方法]以单位叶面积累积虫道数为主要指标,单位叶片累积虫道数和植株危害率为参考指标,研究美洲斑潜蝇在不同月份对几种花卉危害的选择性及危害规律.[结果]美洲斑潜蝇主要危害菊科、蓼科、十字花科和唇形科的花卉,美洲斑潜蝇在不同月份对花卉的危害程度并不相同,对一串红、万寿菊、非洲菊的危害高峰期均处于5月,6、7月依次减轻.对二月兰、金盏菊、三裂绣线菊和百日草的危害程度7月低于6月.整体来看,美洲斑潜叶蝇危害6月较重,7月危害面广,8月危害较轻,这可能与2008年7、8月雨水较多有关.[结论]美洲斑潜蝇在不同月份对花卉的危害程度并不相同,总体上,6月的危害较重,7月危害面较宽,雨水多的月份美洲斑潜蝇的危害程度减轻.

[Objective]The aim was to study the partial tropism of Liriomyza sativae Blanchard on some kinds of flowers.[Method]Parameters of accumulative insect holes per cm2, accumulative insect holes per leaf and harmfulness rate were used to study on the effect of host selection preference and against the law of Liriomyza sativae Blanchard. [Result]Harmfulness of different months was studied for some flowers in this experiment. The harmfulness of Liriomyza sativae is not the same at different months for different flowers. Overall, the harmfulness is heavier in June than other months,wide in July, and have less harm in rainy months. Againsted peak of Salvia spcendens,Tagetes erecta and Gerbera jamesonii was in May, and harmfulness alleviated successively in June and July. Orychragmus violaceus O.E.Schulz.,Calendula officinalis,Spiraea trilobata and Zinnia elegans had less harmfulness in July than in June. The harmfulness of Liriomyza sativae Blanchard is heavier In June than other months,wide in July, and have less harm in August . This might be associated with more rain in July and August of 2008. [Conclusion]The harmfulness of Liriomyza sativae Blanchard is heavier in June than others, wide in July, and have less harm in rainy months.
