| 中文摘要: |
| 柑橘大实蝇Bactrocera minax (Enderlein)，是柑橘的重要害虫。本文基于光学显微镜、扫描电镜、石蜡切片观察，对柑橘大实蝇的内生殖系统形态结构进行研究。结果表明，柑橘大实蝇雌虫内生殖系统主要由卵巢、侧输卵管、中输卵管、受精囊、附腺、前生殖腔（包含布氏交配囊、桑葚腺、生殖腔片）、后生殖腔（阴道和产卵针）组成。雄虫内生殖系统主要由精巢、精泵、输精管、附腺、输入射精管、输出射精管、后附腺和阳茎组成。其雌虫有泄殖腔，位于产卵针前端稍后，雄虫无泄殖腔。雌虫前生殖腔表面被2对肌肉包裹，内部的布氏交配囊、桑葚腺和生殖腔片不易被观察。精泵是一个淡黄色球体，由射精突（精泵内骨骼）、肌纤维（肌肉）、射精囊组成。柑橘大实蝇的内生殖形系统形态结构或组织经过进化，从而适应其伪产卵器的运动、交配、产卵等行为机制。为理解昆虫繁殖生理、进化和多样性，以及昆虫的产卵、交配和代谢物排泄等行为机制提供理论基础。 |
| 英文摘要: |
| Chinese citrus fly, Bactrocera minax (Enderlein) (Diptera: Tephritidae), is an important pest of citrus crops. In this paper, the morphology and structure of internal reproductive system of B. minax was studied on observation of optical microscope, scanning electron microscopy and paraffin section. The results showed that the internal reproductive system of female B. minax mainly consisted of ovaries, lateral oviducts, median oviducts, spermathecae, accessory glands, anterior vagina (bursa copulatrix, ventral receptacle, and signum), and posterior vagina (vagina and ovipositor). The internal reproductive system of the male consists mainly of testis, ejaculatory pump, ejaculatory duct, male accessory gland, input ejaculatory duct, output ejaculatory duct, posterior accessory gland and aedeagus. The female had a cloaca, which was located slightly behind the anterior end of the ovipositor, while the male has no cloaca. The surface of the anterior vagina of the female was covered by two pairs of muscles, and bursa copulatrix, ventral receptacle, and signum in the interior were not easy to be observed. Ejaculatory pump was a pale yellow sphere, composed of the ejaculatory apodeme (the internal skeleton of the ejaculatory pump), muscle fibers (muscles), and ejaculatory pump sac. The morphology and structure or tissue of internal reproductive system of B. minax had evolved to adapt to the mating, egg laying and movement motion mechanism of the pseudo-ovipositor. This study will provide a theoretical basis for understanding the reproductive physiology, evolution and diversity of insect, as well as the insect behavioral mechanisms of oviposition, mating and metabolite excretion. |
