In recent times short horn grasshoppers (i.e. acridids) have been emerged as a potential nutrient resource for livestock in India. But it is necessary to attempt their mass production for a sustainable supply which is also cost effective. In this context the present work aimed to evaluate the ability of annual production of Spathosternum prasiniferum prasiniferum (Walker, 1871). The insects were reared in captivity in natural condition without the aid of any environmental chamber that has been used in all the previous works. For estimation of biomass nymphal survival percentage, number of egg pods laid per female, number of eggs hatched per pod, sex ratio, energy content and dry body weight of adult individuals were taken into consideration. Then projected annual biomass was calculated from the obtained results. The findings were encouraging because we have estimated about 66,326 individuals, or 3.55 Kg of dry biomass i.e. 82,234.33 KJ of energy after one year starting from only one pair. Even though the probable annual biomass was found to be lower than the previous works, still it was a good amount, and heartening for mass scale production. Thus we have concluded the work with a notion that this might encourage small scale start up even by poor farmers who are unable to procure environmental chamber. However, other species should be explored in future that can produce a higher biomass.

关于 Spathosternum prasiniferum prasiniferum (Walker, 1871) (Orthoptera: Acrididae) 作为饲养家畜的潜在昆虫的生物量生产

最近，短角蚱蜢（即蚱蜢）已成为印度牲畜的潜在营养资源。但是有必要尝试大规模生产以实现可持续的供应，这也是具有成本效益的。在此背景下，目前的工作旨在评估 Spathosternum prasiniferum prasiniferum 的年生产能力（Walker，1871）。这些昆虫是在自然条件下人工饲养的，没有任何先前作品中使用过的环境室的帮助。为了估计生物量若虫存活率，考虑了每只雌性产下的卵荚数、每荚孵化的卵数、性别比、能量含量和成年个体的干体重。然后根据获得的结果计算预计的年生物量。研究结果令人鼓舞，因为我们估计大约 66,326 个人，或 3.55 Kg 干生物量，即一年后仅从一对开始产生 82,234.33 KJ 的能量。尽管发现可能的年度生物量低于之前的工作，但仍然是一个很好的数量，并且对大规模生产令人振奋。因此，我们以这样一种观念结束了这项工作，即这可能会鼓励即使是无法获得环境室的贫困农民也能进行小规模创业。然而，未来应该探索可以产生更高生物量的其他物种。并为大规模生产感到振奋。因此，我们以这样一种观念结束了这项工作，即这可能会鼓励即使是无法获得环境室的贫困农民也能进行小规模创业。然而，未来应该探索可以产生更高生物量的其他物种。并为大规模生产感到振奋。因此，我们以这样一种观念结束了这项工作，即这可能会鼓励即使是无法获得环境室的贫困农民也能进行小规模创业。然而，未来应该探索可以产生更高生物量的其他物种。
