Abstract

The pumpkin fruit fly, Bactrocera tau (Walker) (Diptera: Tephritidae) is one of the most serious insect pests of fruits, vegetables and nuts over the world due to its polyphagous nature and high reproductive rate. To gain insight into their sensory system, the external morphology, typology, density, and distribution of sensilla on full bodies of both adult male and female B. tau were observed using a scanning electron microscope. The observed sensilla showed organ as well as sex specific differences. Seven previously described sensilla (two non-olfactory, five olfactory with 17 subtypes) and a new sensillum named as “branched sensilla” (two subtypes) were identified and observed on the different body parts. Olfactory sensilla named as sensilla trichodea and sensilla basiconica were reported on the compound eyes for the first time. Majority of the olfactory sensilla were reported on the head appendages. The presence of species-specific as well as sex-specific branched sensilla in females showed different typology patterns of sensilla. The potential roles of observed sensilla were hypothesized through comparative analysis with prior research. The current findings can provide a reference for understanding the diversity of various olfactory and non-olfactory sensilla in B. tau as well as sex-specific morphological differences and functions of various body parts; thereby, aiding in the development of precise methods for regulating and managing insect behaviour.

南瓜果蝇 Bactrocera tau (Walker) (双翅目:头蝇科)的全身感觉器多样性
南瓜实蝇(Bactrocera tau (Walker))(双翅目:Tephritidae)由于其多食性和高繁殖率,是世界上危害水果、蔬菜和坚果最严重的害虫之一。为了深入了解其感觉系统,我们使用扫描电子显微镜观察了雌雄成虫全身感觉器的外部形态、类型、密度和分布情况。观察到的感觉器显示出器官和性别的差异。在不同的身体部位上发现并观察到了七个以前描述过的感觉器(两个非嗅觉感觉器,五个嗅觉感觉器,共 17 个亚型)和一个被命名为 "分枝感觉器 "的新感觉器(两个亚型)。在复眼上首次发现了名为 "三毛感觉器 "和 "基本感觉器 "的嗅觉感觉器。据报道,大部分嗅觉感受器位于头部附属物上。雌鼠身上存在的物种特异性和性别特异性分枝感觉器显示了不同类型的感觉器模式。通过与之前研究的比较分析,对观察到的感觉器的潜在作用进行了假设。目前的研究结果可为了解陶氏虫各种嗅觉和非嗅觉感觉器的多样性以及身体各部分的性别特异性形态差异和功能提供参考,从而有助于开发调节和管理昆虫行为的精确方法。

期刊介绍: The journal publishes original research papers, reviews and method papers. While reviews should be designed as comparative surveys, summarizing the current knowledge from an evolutionary perspective, method papers should present new approaches or reviews on methods used in animal morphology. The research papers should be based on morphological investigation of invertebrates and vertebrates at the macroscopic, microscopic and ultrastructural level, including embryological studies.
