Larval density is an important factor modulating larval resource-acquisition, influencing development of insects. This study aimed to evaluate the effect of larval density and substrate content on some life-history parameters of Musca domestica Linnaeus, 1758 (Diptera: Muscidae). This research was carried out from March 2019 through September 2019 at Animal Physiology Laboratory of Ondokuz Mayıs University, Samsun, Turkey. Groups of 25, 100, 200, and 400 newly hatched M. domestica larvae were transferred to a polyethylene cup filled with different substrates (i.e., wheat bran, poultry meal, soybean meal) and kept at 25°C, 62% RH with a photoperiod of 12:12 (L:D) h. A two-way analysis of variance (Two way ANOVA) was used to analyze the data on the percentage of pupal and larval survival development time, pupal, and adult weight to evaluate the effect of density and rearing substrate. In this study, increasing larval density and nutrient content of food led to changes in the larval and pupal development time of M. domestica. The results also indicated that the weight of pupae and adult survival was negatively affected by increasing larval density. The wheat bran diet was superior to the other diets for all parameters tested. Our study indicated that life history parameters of Musca domestica are affected by the rearing conditions.
幼虫密度是调节幼虫资源获取的一个重要因素，影响昆虫的发育。本研究旨在评估幼虫密度和基质含量对家蝇（双翅目：蝇科）一些生活史参数的影响。这项研究于 2019 年 3 月至 9 月在土耳其萨姆松的奥登尼兹·迈赫迈特大学动物生理学实验室进行。将 25、100、200 和 400 只新孵化的家蝇幼虫分别转移到装满不同基质（即麦麸、禽肉粉、大豆粉）的聚乙烯杯中，并在 25°C、62%相对湿度和 12:12（L:D）h 的光周期下保存。采用双因素方差分析（Two way ANOVA）来分析幼虫存活率、幼虫和蛹发育时间、蛹和成虫体重的百分比数据，以评估密度和饲养基质的影响。在本研究中，增加幼虫密度和食物的营养含量会改变家蝇的幼虫和蛹发育时间。结果还表明，随着幼虫密度的增加，蛹和成虫的存活率呈负相关。在所有测试的参数中，麦麸饲料均优于其他饲料。我们的研究表明，家蝇的生活史参数受饲养条件的影响。
