摘要。印度粉蛾（Plodia interpunctella）正成为研究蚕丝的重要生物学模型。虽然在材料科学和医学上有许多潜在的应用，但这个物种的丝绸生产的许多方面仍然未知。本文通过测量幼虫游走和蛹蛛丝的宽度来表征斑间瓢虫蛛丝的特征，发现蛹蛛丝明显比幼虫蛛丝粗。我们还报告了在我们实验室饲养的群体中蛹产丝的种内变异，极少数个体完全放弃蛹产丝（< 4%）。过度拥挤对成丝没有影响，但温度升高会降低蛹的成丝量。
ABSTRACT. The Indian meal moth (Plodia interpunctella) is becoming an important biological model to study silk. While there are many potential applications to materials science and medicine, many aspects of silk production in this species remain unknown. Here we characterize the silk of P. interpunctella by measuring the width of larval wandering and pupal silk strands and find that the latter is significantly thicker than the former. We also report intraspecific variation in pupal silk production in our lab-reared colony with a very small number of individuals forgoing pupal silk production entirely (< 4%). Overcrowding had no effect on silk formation, but exposure to elevated temperature reduced pupal silk production.
