The shoot and fruit borer, Earias vittella Fab. (Lepidoptera: Nolidae) is an important and most devastating insect pest on okra and cotton. The pest mainly responsible for causing significant direct damage to tender shoots and fruits of okra, flowers and green bolls of cotton causing net yield loss in both crops. Many non-chemical control strategies have been developed under the insect pest management program, A complete knowledge on the antennal morphology of E. vitella is essential for future electrophysiological and behavioural studies. In the present study, the antennal morphology and types of sensilla on the antennae of both sexes of E. vitella were examined using light and scanning electron microscopy. Nine distinct types of sensilla were identified on the antennae of both sexes: sensilla trichodea, sensilla basiconica, sensilla coeloconica, sensilla auricillica (multiporous), sensilla chaetica, uniporous peg sensilla (uniporous), sensilla styloconica, sensilla squamiformia and bohm bristles (aporous). Among all sensilla, the most widespread are multiporous sensilla trichodea with 42.90 ± 1.77/flagellomere in male and 37.38 ± 1.38/flagellomere in female. Sensilla basiconica were the second most common sensillum type in male antennae with 15.67 ± 1.92/flagellomere. Other multiporous sensilla such as auricillica (11.90 ± 0.99) and coeloconica (4.57 ± 0.25) were significantly more abundant in female than in male antennae. Results of the study provide morphological evidence that E. vitella antennae possess microscopic cuticular structures that can play a role in perception of pheromones, plant odours and other chemical stimulants. This will open up opportunities to assess the possibility of using pheromones and plant-derived compounds for the monitoring or management of E. vittella moths in the agricultural landscapes.

芽和果实蛀虫，Earias vittella Fab。（鳞翅目：Nolidae）是秋葵和棉花上的一种重要且最具破坏性的害虫。这种害虫主要对秋葵的嫩芽和果实、花卉和棉花的青铃造成严重的直接损害，导致两种作物的净产量损失。在害虫管理计划下已经开发了许多非化学控制策略，关于E. vitella触角形态的完整知识对于未来的电生理和行为研究至关重要。在本研究中，E. vitella两性触角上的触角形态和感受器类型使用光学和扫描电子显微镜检查。在两性的触角上鉴定出九种不同类型的感受器：毛状感受器、基本感受器、腔感受器、耳状感受器（多孔）、毛皮感受器、单孔钉感受器（单孔）、柱状感受器、鳞状感受器（多孔感受器） . 在所有感受器中，最普遍的是多孔感受器 trichodea，男性为 42.90 ± 1.77/flagellomere，女性为 37.38 ± 1.38/flagellomere。基本感器是雄性触角中第二常见的感器类型，为 15.67 ± 1.92/鞭毛。其他多孔感器如 auricillica (11.90 ± 0.99) 和 coeloconica (4.57 ± 0.25) 在雌性触角中明显多于雄性触角。研究结果提供的形态学证据表明E. vitella触角具有微小的表皮结构，可以在信息素、植物气味和其他化学兴奋剂的感知中发挥作用。这将为评估使用信息素和植物衍生化合物监测或管理农业景观中的E. vittella蛾的可能性提供机会。
