摘要
通过室内观察,研究了悬铃木方翅网蝽的取食、产卵、孵化、蜕皮等行为。结果表明,其取食时头部有上下抽插动作,每次平均取食时间为11.2min,若虫有群集取食习性。雌虫经过触探确定产卵位置,通常选择在叶背面的叶脉交叉处或叶脉两侧产卵。卵的孵化过程需10～20min,分为顶开卵盖、展开附肢、晃动身体和脱离卵壳4个步骤。各龄若虫蜕皮的过程基本相同,经过外骨骼溶解、蜕皮、外骨骼硬化后进入下一虫态。成虫会有很频繁的梳理行为,既有对触角和足的梳理,又有对腹部和口器的梳理,其中对触角的梳理最为频繁。
The behaviors of feeding,ovipositing,hatching and ecdysising of Corythucha ciliate(Say) were observed in the lab.The results showed that the feeding sites were mainly at the edge of leaf veins and the borders of the leaves.The head of adult and nymph would thrust up and down when feeding,and average feeding time last 11.2min.The nymph often feed assembly.When ovipositing,the eggs often were laid in the infall of the leaf veins or on the both sides of the relatively coarse veins via two probes.The hatch of C.ciliata eggs was about 10 to 20 minutes needed,during which the four steps,opening the egg lid,expanding the appendage,shaking the body,and breaking away the egg shell,were divided.The moults processes of various nymph were the basically same and included the dissolution of exoskeleton,moult and harden exoskelet.The adults had frequent grooming behaviors and not only comb the antennae and feet,but also abdomen and mouthparts,in which the antennae's combing was the most frequently.
