【摘要】 欧洲蛷螋的雌性通过护卵活动可以有效地抑制卵表面霉菌的生长，以保证胚胎的正常发育。但是抚幼行为，特别是接触活动的生物学功能至今尚不明确。本实验表明：幼虫可通过雌虫间接地获取营养物质，从而明显地提高其发育速率和存活率；而单纯的抚幼活动对幼虫的生长和存活并无影响。更多还原

【Abstract】 In common earwig, For ficula auricularia L., parental care is necessary for the development of eggs. However, so far the selective value of family group remains as an outstanding question.Our experiment shows that there is a female contribution to larval food intake, and this feeding aid canimprove significantly the larval survival rate and development. However, the female care alone has noeffect on larval survival and development.更多还原
