摘要
Objective] Field and laboratory observation was conducted to investigate Clubiona corrugate. [Method] The trials investigated the bio-ecology and behavior of the spider C. corrugate. [Result] The spider overwintered with spiderlings, adults and instars turn into adults after 6-8 molts. It had 2-3 generations each year in Hunan, and it owned the character of overlapping of generation in paddies. The average duration of generations of C. corrugate was 158.2 days, and the survival days av-eraged 223.2 days. The female and male mated several times without cannibalistic behavior, average number of eggs female laid throughout its adult life was 371.5, and hatchability can get 85.4%. The sex ratio was 1∶1. Its capability of resistance to starvation and drought was strong. Through indoor observation, the spider can sur-vive 25-61 days under the condition of no water and food. [Conclusion] The behav-ior of C. corrugate was also recorded in detail, and female usual y has a strong a-bility to protect their egg-sacs and spiderlings. At present, the bio-ecology and be-havior of the spider C. corrugate had not been reported.
[目的]探究了褶管巢蛛(Clubiona corrugata)的生物生态学特性。[方法]分别在田间和试验室条件下对褶管巢蛛(Clubiona corrugata)进行观察。[结果 ]褶管巢蛛以成、若蛛越冬,若蛛6-8次蜕皮发育成成蛛。在湖南1年可发生2-3代,田间具世代重叠,世代平均历期158.2天,寿命223.2天。雌、雄蛛均可多次交配,雌蛛一生平均产卵371.5粒,孵化率为85.4%。雌雄性比为1∶1。在稻田中可捕食稻飞虱、稻叶蝉、纵卷叶螟、稻苞虫等多种害虫。抵抗干旱和饥饿的能力比较强,经室内观察,该蛛在无水无食的条件下可生存25-61天。[结论]试验中褶管巢蛛的行为被详细记录,雌蛛通常有比较强的保护蛋囊和幼蛛的能力。目前国内外未见有关褶管巢蛛生物生态学特性的研究报道。
