摘要: 蚧科昆虫的雄虫形态对其分类具有重要意义,但关于扶桑绵粉蚧雄虫的研究较少;为进一步补充扶桑绵粉蚧的分类学信息,对扶桑绵粉蚧雄虫发育过程中的形态变化进行了研究。结果表明,扶桑绵粉蚧卵为长椭圆形,呈半透明,橙黄色。1龄若虫,浅黄绿色,孵出后即可快速扩散。2龄若虫,初期体表光滑,呈明黄色,背部可见2条黑斑,体缘有明显的齿状凸起;末期可在形态上区分雌、雄虫。雄虫预蛹期1~2 d,身体狭长;预蛹初期分泌白色的丝状物。蛹期的雄虫包裹在柔软的丝茧中,蛹为离蛹,呈椭圆形,虫体表面被有蜡粉。雄成虫,体型较小,身体呈筒状,具有发达的单眼,口器退化致无取食能力,触角细长,前翅发达,后翅退化成平衡棒,腹部末端有2对白色的长蜡丝。

Abstract: Despite male morphology was of great importance for Coccoidea classification, little information about Phenacoccus solenopsis males was published. To supplement taxonomic information of P. solenopsis, morphological changes during individual development of P. solenopsis males were described in this study. The results showed that P. solenopsis eggs were oval, slightly translucent and pale orange yellow. The first instar nymph was yellowish green and moved fast. For the early second instar nymph, its body surface was smooth and bright yellow with two visible black spots on the back. Male and female individuals could be distinguished by morphological character in late-2nd instar stage. The pre-pupa stage of the males lasted 1-2 d. In this stage, the body was long and narrow, and the males began to produce white silk to cover their whole body. Pupae were in a soft silky cocoon. In the cocoon, the body was covered by white wax power. Male adults showed in barrel-shaped body, developed ocellus, degenerated mouthpart, long antennae, thin front wing, poisers developed from the degenerated hind wings, and two pairs of long wax filaments at the terminal abdomen.
