The reproductive and diapausing adult females of brachypterous morph and macropterous females with reproductive arrest of non-diapause type, originating from the laboratory cultures of Pyrrhocoris apterus, were studied for their feeding and drinking behaviour, digestive enzyme activities, and carbohydrate and lipid contents. The highest feeding and drinking activities were observed in reproductive brachypters, the lowest in macropters. Macropters also differed from brachypters by lower activities of gut lipase, peptidase and protease, lower concentration of haemolymph sugars, and lower weight of fat body, which probably reflects their low feeding activity. The total content of fat body lipids was also lower in macropters (0.6 mg) than in reproductive and diapausing brachypters (4.6 and 7.5 mg, respectively) on day 14. A very high amount of glycogen was found in the fat body of diapausing brachypters, 363 micrograms on day 14, as opposed to 15 and 80 micrograms in macropterous and reproductive brachypterous females, respectively. The obtained data indicate that the most important difference between macropterous and brachypterous females with different types of reproductive arrest consists of an enhanced mobilization of lipids for dispersal in macropters and accumulation of energetic reserves for hibernation in brachypters.
对源自实验室培养的黑腹果蝇短翅型生殖和滞育成年雌虫以及非滞育型生殖停滞的长翅型雌虫，研究了它们的取食和饮水行为、消化酶活性以及碳水化合物和脂质含量。在生殖短翅型中观察到最高的取食和饮水活动，在长翅型中最低。长翅型与短翅型的不同还在于肠道脂肪酶、肽酶和蛋白酶的活性较低，血淋巴糖浓度较低，以及脂肪体重量较低，这可能反映了它们较低的取食活动。在第14天，长翅型脂肪体脂质的总含量（0.6毫克）也低于生殖和滞育短翅型（分别为4.6毫克和7.5毫克）。在滞育短翅型的脂肪体中发现了非常高的糖原含量，第14天为363微克，而长翅型和生殖短翅型雌虫分别为15微克和80微克。所获得的数据表明，具有不同类型生殖停滞的长翅型和短翅型雌虫之间最重要的差异在于，长翅型为扩散而增强了脂质的动员，而短翅型为冬眠积累了能量储备。
