本文研究了过度拥挤对埃及伊蚊幼虫的影响。并说明在高密度条件下对应激的补偿反应。测试的密度水平为每80 ml溶液40、160、280、400、520、640、960和1280只幼虫。评估的一些参数包括幼虫发育率、幼虫-蛹蜕皮的开始和速率、蛹重量和幼虫存活率。
随着密度的增加，幼虫的发育率急剧下降。蛹的重量也减少了过度拥挤。结果表明，随着密度的增加，整个转移的幼虫蛹蜕皮模式。揭示了性别、生存和体重之间的关系作为密度增加的函数。
提出了一种处理密度关系的描述性模型。它试图发展一些统一的术语，以便在过度拥挤的许多方面的研究之间提供更好的比较。
An experiment was performed to investigate the effects of overcrowding in larval Aedes aegypti (L.) and to illustrate the compensatory responses to stress in highdensity conditions. Density levels tested were 40, 160, 280, 400, 520, 640, 960, and 1280 larvae per 80 ml of solution. Some of the parameters evaluated included rates of larval development, onset and rates of larval-pupal ecdysis, pupal weights, and larval survival.
Rates of larval development were drastically reduced as density was increased. Pupal weights were also reduced by overcrowding. Results indicated entire shifts in patterns of larval-pupal ecdysis as the densities were increased. Relationships between sex, survival, and weight as a function of increasing density were revealed.
A descriptive model dealing with density relationships is presented. It attempts to develop some uniformity of terminology, to provide better comparisons between studies of the many aspects of overcrowding.
