| 中文摘要: |
| 枸杞红瘿蚊是宁夏枸杞上重要成灾害虫之一。枸杞白瘿蚊是继枸杞红瘿蚊后在宁夏枸杞上新发现的另一种瘿蚊科害虫。两种瘿蚊均以幼虫为害宁夏枸杞幼嫩花蕾使其不能正常发育,但形成的虫瘿结构差异明显。本文通过外部形态观察、石蜡切片等方法对两种虫瘿发育过程中的外部形态特征、内部组织结构进行了对比。结果表明,两种瘿蚊幼虫的取食不会引起花部结构的增加或缺失,但均影响花部结构发育,使其无法正常开花结果。枸杞红瘿蚊主要造成子房细胞数量增多形成虫瘿,枸杞白瘿蚊主要造成花冠细胞体积增大形成虫瘿。此外两种虫瘿在花柱、花丝、蜜腺、花药、花柄等处均存在一定差异。 |
| 英文摘要: |
| Gephyraulus lycantha (wolfberry red gall midge, WRGM) is one of the most important pests of Lycium barbarum, and Contarinia sp. (wolfberry white gall midge, WWGM) is another newly found flower gall midge. These two midges can both induce flower bud galls that cannot develop normally, but the gall structures induced by the two species of gall midges are obviously different. Here, the external morphology and internal tissue structure of the two kinds of flower galls during development were compared by means of external morphological and paraffin section observations. The results showed that the feeding by larvae of the two gall midge species did not cause any increase or loss in floral structure, but both affected the development of floral structure and prevented them from flowering and fruiting normally. WRGM mainly induced an increase in the number of ovary cells leading to an enlarged appearance of galls, while WWGM mainly induced an increase in the size of corolla cells leading to an enlarged appearance of galls. There were also some differences in the style, filament, nectary, anther, and stalk. |
