【摘要】：以茶小绿叶蝉、茶蚜和白背飞虱3种农业上重要的半翅目害虫为研究对象,观察比较它们在水面上的疏水行为及其前跗节的形态结构.结果表明,白背飞虱成虫和若虫均可站立于水面并具有较强的滑行能力,表明其前跗节疏水性最强;茶小绿叶蝉成虫可站立于水面,若虫足易陷入水中,表明成虫的前跗节疏水性强于若虫;茶蚜成虫和若虫足均陷入水中,表明其前跗节无疏水作用,但茶蚜成虫和若虫在水面均有聚集抱团现象;这3种昆虫都无法站立于大豆油面.电镜观察发现,茶小绿叶蝉成虫的前跗节较若虫更加扁平,爪中垫为一对椭圆形吸盘状结构,且表面附着的刺体数量显著多于若虫;茶蚜成虫和若虫具有一对发达的爪及2根棍棒状中垫毛,缺少爪垫及爪中垫;白背飞虱成虫和若虫具有发达的杯状吸盘结构的爪中垫.
[Abstract]:Three important hemiptera pests in agriculture, tea green leafhopper, tea aphid and white back planthopper, were used to observe and compare their hydrophobic behavior on the water surface and the morphological structure of the anterior tarsal. The results showed that both adults and nymphs could stand on the water and had strong gliding ability, which indicated that the anterior tarsal node was the most hydrophobic, while the adult of the tea green leafhopper could stand on the water, and the nymphs were prone to fall into the water. The results showed that the hydrophobicity of the anterior tarsal node of the adult was stronger than that of the nymphs, and that both the adult and the nymphs were in water, indicating that the anterior tarsal node had no hydrophobic effect, but both the adults and the nymphs were clustered on the water surface. None of the three insects could stand on soybean oil noodles. The results of electron microscope showed that the anterior tarsal ganglia of the adult was more flat than that of the nymphs, and the clawed with a pair of elliptical sucker structures, and the number of spines attached on the surface was significantly more than that of the nymphs. The adults and nymphs of the tea aphid have a pair of developed claws and two clavelike middle mats, but they lack the claw pads and the middle paw mats, while the adults and nymphs of the white back planthopper have developed cup sucker structure.
