The paddy field grasshopper Oxya velox fed ad libitum on fresh leaves of the grass Digitaria is reared in the laboratory from hatching to death. A female grows to a maximum size of 218±40 mg wet weight on the 240th day, while a male attains a maximum of 132±17 mg weight on the 149th day. Total food intake amounts to 1341 and 557 mg dry grass for a single female and a single male respectively. Feeding rate averages 167 mg wet grass/g wet weight of grasshopper/day. Assimilation efficiency amounts to 27% in both sexes. Unassimilable faeces amount to 1 g for a female and 0.4 g for a male. About 32% of the assimilated food is used for total growth in either sex. Exuviae amount to 4% and 5% of the assimilated food in the female and the male respectively. The average amount of (dry) body substance used for reproduction is 82 mg in fertilized and 10 mg in the parthenogenetic female. A fertilized female consumes more food than a virgin. A female produces 3.5, egg pods on a average, each containing about 4 eggs. About 14% of the assimilated food energy is required for reproduction by a female and 3% by a male. At death the male contains 26% and the female 12% of the assimilated food energy respectively. The energy budget of O. velox is discussed in comparisn with that of Bombyx mori, a lepidopteran.
将稻田蝗虫中华稻蝗从孵化到死亡在实验室中用马唐草的新鲜叶片随意喂养。一只雌性在第240天生长到湿重最大为218±40毫克，而一只雄性在第149天达到最大体重132±17毫克。单只雌性和单只雄性的总食物摄入量分别为1341毫克和557毫克干草。摄食率平均为167毫克湿草/克湿重蝗虫/天。两性的同化效率均为27%。雌性不可同化的粪便量为1克，雄性为0.4克。在两性中，约32%的同化食物用于总生长。蜕皮分别占雌性和雄性同化食物的4%和5%。用于繁殖的（干）身体物质平均量在受精雌性中为82毫克，孤雌生殖雌性中为10毫克。受精雌性比未交配雌性消耗更多食物。一只雌性平均产3.5个卵荚，每个卵荚约含4个卵。雌性繁殖所需的同化食物能量约为14%，雄性为3%。死亡时，雄性和雌性分别含有同化食物能量的26%和12%。将中华稻蝗的能量预算与鳞翅目家蚕的能量预算进行了比较讨论。
