摘要
亚洲柑橘木虱Diaphorina citri Kuwayama是柑橘黄龙病的传播媒介.本文利用SteREO Discovery V20体视显微镜对亚洲柑橘木虱成虫内生殖系统进行解剖观察,并探索了亚洲柑橘木虱雌雄成虫内生殖系统的形态变化规律.结果表明:雄虫内生殖系统由1对精巢、1对输精管、1个精泵、1个射精管、1对附腺和1个贮精囊组成.雌虫内生殖系统由1对卵巢、1对侧输卵管、1个中输卵管、2个附腺、1个黏腺和1个受精囊组成.交配前期和交配期的雄虫精巢饱满,精巢在交配后期明显萎缩.交配期和交配后期的雄虫贮精囊都明显大于交配前期的贮精囊.雌虫受精囊在交配前期、交配期和交配后期依次增大,交配前期的受精囊呈不饱满状态,交配期和交配后期受精囊呈饱满状态,内有白色精包.交配后期的雌虫卵巢内有大量成熟的橙黄色卵.
Abstract
Diaphorina citri Kuwayama(Hemiptera: Psyllidae)is the insect vector of Huanglongbing (HLB)that cause serious damage to the citrus production worldwide.In the present study, the internal reproductive system of D.citri was dissected and observed under the SteREO Discovery V 20 stereomicroscope to explore its morphological changes in different developmental periods.The results showed that the internal reproductive system of D.citri male adult was composed of testis,seminal vesical, accessory gland,vas deferens,sperm pump and ejaculatory duct.While that of D.citri female adult was composed of ovaries, spermatheca, bursa copulatrix, common oviduct, lateral oviducts, colleterial gland and accessory glands.The testes of male in the premating and mating period were fully filled and significantly larger than that in the post-mating period.The testis of male adult was atrophic in the post-mating period.The seminal vesical in the mating and later-mating period was significantly larger than that in the premating period.Female spermatheca gradually enlarged from the premating to the post-mating period, while the famle spermathecas in the mating period and post-mating period were fully filled and there were white fine sperm package inside the spermathecas.There were plenty of mature orange-yellow eggs in the female ovaries in the post-mating period.
