-
摘要: 朱红毛斑蛾Phauda flammans 主要为害榕树Ficus microcarpa。为了迅速准确鉴别蛹和成虫性别,通过体视显微镜进行观察。结果表明,雌蛹第8 腹节有1 纵裂缝,两侧平坦,第9 腹节和第10 腹节分节不明显;雄蛹第9腹节有1 明显生殖孔裂缝,略微突起,第9 腹节和第10 腹节分节明显。雄虫体型较雌虫略小,雌虫触角鞭节白色,雄虫黑色;雌虫腹面体毛黑色,雄虫腹面体毛灰白色。雌虫腹部末端有明显的产卵器,轻挤腹部末端,伸出1 黄色囊状腺体;雄成虫腹部末端有1对黑色尾须,轻挤腹部末端,抱握器分开,阳具外突。朱红毛斑蛾雌成虫的生殖系统包括1 对卵巢、卵巢管、1 根中输卵管、2 根侧输卵管、受精囊、受精囊腺、阴道支囊、导精管、交尾囊、1 对附腺、产卵器;雄成虫的生殖系统包括1 个睾丸、1 对输精管、1 对附腺、双精管、单精管、阳茎和抱握器。Abstract: Phauda flammans damages Ficus. Observation on morphological properties and sexing was carried out by stereo microscope. The resultdemonstrated that there is one longitudinal cleft at the 8th abdominal segment in female pupa and one at the 9th abdominal segment in male one. Malemoth was slightly smaller in size than female one.Female moth has whiteantenna while male has black one. Ventral body hairs of female moth areblack, while that of male gray. By the end of female abdomen there is an obvious ovipositor, yellow vesicular gland. There are 1 pairs of black cercuson male adult abdominal end. Squeezing the abdomen end, claspers separated, penises protruded. The reproductive system of female P.flammansmoth includes one pair of ovaries, ovarioles, egg tube, spermathecae, etc. The reproductive system of male P. flammansmoth includes atestes, one pair of vas deferens, one pair of accessory gland, double precision tube, single precision tube, penis and claspers.
