摘要

图中显示了一种原生寄生于新热带蝇属(双翅目:绢蝇科)幼虫的原生寄生昆虫Utetes anastrephae(膜翅目:绢蝇科)未成熟阶段的形态。本研究旨在研究两种寄主——斜Anastrepha obliqua和芦丁Anastrepha ludens幼虫的未成熟阶段及其形态变化。通过解剖宿主的日常显微镜观察和照片来确定发育过程中的结构和形态变化。拟寄生物的未成熟发育对应于全变性昆虫,有三个明确的阶段:卵(2天),幼虫和三个幼虫(大约8天)和蛹(6天)。两种寄主的发育时间相似。雄性和雌性分别在17天和18天内完成月经周期。在卵-一龄发育过程中,寄主通过黑化作用和包封作用产生的拮抗作用是导致死亡的主要因素。这些结果为利用该寄生虫对果蝇进行生物防治提供了基础知识。

Immature stages of Utetes anastrephae (Hymenoptera: Braconidae) developed in Anastrepha fruit fly larvae (Diptera: Tephritidae)

The morphology of the immature stages of Utetes anastrephae (Hymenoptera: Braconidae), a native parasitoid of larvae of flies of the Neotropical genus Anastrepha (Diptera: Tephritidae), is shown. This study aimed to characterize the immature stages and morphological changes in the development of the koinobiont endoparasitoid in two species of larval hosts, Anastrepha obliqua and Anastrepha ludens. The definition of structures and morphological changes during development was made through daily microscopic observations and photographs of dissected hosts. The immature development of the parasitoid corresponds to a holometabolous insect with three well-defined stages: egg (two days), larva with three larval instars (approximately eight days), and pupa (six days). Similar development times were obtained in the two host species. Males and females completed their cycle in 17 and 18 days, respectively. During egg-first instar development, host antagonistic activity through melanization and encapsulation as mortality factors was evident and frequent only in A. obliqua. These results serve as basic knowledge for the use of this parasitoid in the biological control of fruit flies.

期刊介绍: Arthropod Structure & Development is a Journal of Arthropod Structural Biology, Development, and Functional Morphology; it considers manuscripts that deal with micro- and neuroanatomy, development, biomechanics, organogenesis in particular under comparative and evolutionary aspects but not merely taxonomic papers. The aim of the journal is to publish papers in the areas of functional and comparative anatomy and development, with an emphasis on the role of cellular organization in organ function. The journal will also publish papers on organogenisis, embryonic and postembryonic development, and organ or tissue regeneration and repair. Manuscripts dealing with comparative and evolutionary aspects of microanatomy and development are encouraged.
