中文摘要 | 本文研究了南美斑潛蠅對47種植物(Liriomyza huidobrensis)的寄主取食選擇性。對植物葉片進行了組織切片,對所選的15個葉片組織結構的特徵進行顯微測量。各葉片組織特徵與南美斑潛蠅寄主取食選擇性的相關性分析顯示,其取食選擇性與葉片含水率呈顯正相關,而與葉片表皮外壁厚度、柵欄組織和海綿組織的緊密程度呈顯負相關。南美斑潛蠅雌成蟲的刺探、取食行為受葉片組織結構的影響。葉片組織表皮外壁厚度、柵欄組織和海綿組織緊密程度高以及含水量低的植物,對南美斑潛蠅成蟲的選擇性有較強的物理組隔作用。葉片的柵欄組織和海綿組織緊密程度高,對南美斑潛蠅幼蟲的取食活動有一定的限制作用。植物片含水量低可能不利於南美斑潛蠅幼蟲的生長發育。 |
英文摘要 | Host feeding selection by the female pea leafminer, Liriomyza huidobrensis, on 47 species of plants was studied. The leaves were sectioned by microtome, and 15 characteristics of the leaf tissue structure were measured under a microscope. Correlation analysis between host feeding selection and leaf tissue structure indicated that the preference of host feeding selection was positively correlated with the percentage of moisture content of leaves and negatively with thickness of the epidermis wall, and densities of the palisade and spongy tissues of leaves. Leaf tissue structure was influential in feeding and probing behavior of female L. huidobrensis. So, thickness of epidermis wall, densities of the palisade and spongy tissues can act as a physical barrier to female oviposition. Furthermore, higher densities of palisade and spongy tissues can be considered a resistant trait which affects mining of leafminer larvae as well. As a result, plants with lower leaf moisture content may not be suitable for the development of L. huidobrensis. |
