在实验室条件下，研究了金龟子隐翅虫在不同常量营养素组成的饲料中的存活和繁殖情况。对饲喂每种试验饲料的雌性动物的性器官进行解剖，以评估卵巢随时间的发育。吃碳水化合物丰富饮食的成年人比吃其他饮食的成年人活得更长，但这种饮食提供的营养不足以繁殖。摄食高蛋白饲料的雌性具有较高的繁殖力，但与摄食高碳水化合物的成虫60-70d相比，繁殖期成虫的平均寿命显著缩短20-30d。相比之下，提供高脂饮食的成年鼠存活率和繁殖力都较低。总体而言，结石形成前毛囊的发育受到饮食制度和开始特定饮食的天数的显著影响。饲喂富含蛋白质饲料的雌性仔猪，在开始饲喂2周后，卵泡大小增加了0.5倍。相比之下，雌性富含碳水化合物的卵泡发育缓慢，雌性高脂饮食的卵泡退化。在卵巢成熟方面，以富含蛋白质的食物喂养的女性大多含有卵黄生成和绒毛膜形成的卵泡。相反，高碳水化合物饮食的雌性大鼠的卵巢小管大部分被卵泡发育前期和卵黄发育阶段所占据，而脂肪丰富饮食的雌性大鼠在整个实验过程中卵泡仍处于发育前期阶段。
The survival and reproduction of the beetle Paederus fuscipes Curtis on diets that differed in macronutrient composition were investigated in the laboratory. The sex organs of females fed each test diet were dissected to evaluate the ovarian development over time. Adults fed on a carbohydrate-rich diet lived longer than adults fed the other diets, but this diet provided insufficient nutrients for reproduction. Females fed on a protein-rich diet had high fecundity; however, the mean longevity of reproductive adult P. fuscipes significantly was shortened by 20-30 d compared with longevity of 60-70 d for adults fed a carbohydrate-rich diet. In contrast, adults that were provided lipid-rich diet had low survival and fecundity. Overall, the development of previtellogenic follicles was significantly affected by diet regime and days since starting a particular diet. The follicle size of females given protein-rich diet increased 0.5-fold 2 wk after beginning the diet. In contrast, the development of the follicles was slow in females given the carbohydrate-rich diet and the follicles degenerated in females given the lipid-rich diet. In terms of ovarian maturation, females fed on a protein-rich diet contained mostly vitellogenic and chorionated follicles. In contrast, the ovarioles of females on the carbohydrate-rich diet were largely occupied with previtellogenic and vitellogenic follicles, whereas for a lipid-rich diet, the follicles remained at the previtellogenic stage throughout the experiment.
