Female false black widows, Steatoda grossa (Araneae: Theridiidae), build energy-costly webs. We tested the hypotheses (H1, H2) that females prefer their own webs and the chemical extract of their own webs to those of conspecifics, and (H3) that mated females discern between their own egg sacs and those of conspecifics. In choice bioassays, females indiscriminately accepted both their own webs and egg sacs and those of conspecific females, although they chose extracts of webs based on their chemical cues. The females’ indiscriminate responses to webs or egg sacs are likely due to a lack of selection pressure to reject webs or egg sacs of conspecific females.

“我的或你的”:假黑寡妇蜘蛛(Araneae:Theridiidae)对自己的和同种的网和卵囊的不分青红皂白的反应
雌性假黑寡妇 Steatoda Grossa (Araneae: Theridiidae) 构建耗能的网。我们测试了假设 (H1, H2),即雌性更喜欢自己的网和自身网的化学提取物,而不是同种的,以及 (H3) 交配的雌性区分自己的卵囊和同种的卵囊。在选择生物测定中,雌性不分青红皂白地接受了自己的网和卵囊以及同种雌性的网和卵囊,尽管它们根据化学线索选择了网的提取物。雌性对网或卵囊的不加选择的反应可能是由于缺乏拒绝同种雌性的网或卵囊的选择压力。
