| 长角直斑腿蝗是一种鸟类昆虫饲料，具有较高市场经济价值。在广州从化对长角直斑腿蝗进行了初步的人工大量繁殖试验。分别采用了箱养和棚养两种方式，比较了不同饲养条件下长角直斑腿蝗成虫的存活情况，昼夜温差和昼夜湿度差的变化对成虫存活的影响，以及在棚养条件下各棚成虫死亡的差异。结果显示，虽然棚养的成虫密度（?=29.87±2.51头/m3）远低于箱养成虫（?=2371.26±87.23头/m3），但成虫死亡率（88.02±0.07%）却是箱养成虫（40.71±0.11%）的2.16倍，差异显著。昼夜温差和昼夜湿度差的变化与成虫死亡无显著的相关性（箱养、G棚和I棚）或相关性程度低（F棚：R2=0.1596）。在棚养条件下，F棚成虫的死亡73.94%发生在4月，而G棚和I棚在4月死亡的成虫不及其死亡成虫总数的50%，分别为47.18%和40.80%，各棚之间差异极显著。棚养成虫的死亡可能主要是与成虫交配产卵等相关的生物学因素有关。在棚养条件下，长角直斑腿蝗的卵能正常发育并孵化，若虫能正常蜕皮并发育至3龄，然而3龄若虫在发育初期突然大量死亡，其原因有待探究。解决3龄若虫大量死亡的问题是人工繁殖长角直斑腿蝗的关键技术所在。 |

| Stenocatantops splendens (Thunberg) is one of the live food of entomophagous birds with the highest economic value in commercial markets. Trial mass-rearing of S. splendens was conducted in Guangzhou Conghua, Guangdong Province, China. Adult S. splendens collected from wild were reared in cages and in mesh-houses, respectively, before which both ♀ and ♂ had been mated. Death of adults was compared between cage rearing and mesh-house rearing, and among mesh-houses, and influence of diurnal variation of temperature and relative humidity on adult mortality was analyzed. And mass death of the 3rd instar in mesh-house rearing was discussed. Results showed that, although adult density in mesh-house (?=29.87±2.51 adult /m3) was extraordinarily lower than in cage (?=2371.26±87.23 adult/m3), adult mortality (88.02±0.07%) in mesh-house was 2.16 times higher than in cage (40.71±0.11%), which was statistically significantly different. Influence of diurnal variation of temperature and relative humidity on adult mortality was either not statistically significantly different for cage-rearing and mesh-houses G and I, or of low correlation for mesh-house F (R2=0.1596). 73.94% of adult death in mesh-house F occurred in April, while adults died in the same month in mesh-houses G and I were both less than half of the respective total death, with 47.18% and 40.80% for mesh-house G and I, respectively. It is supposed that adult death in mesh-houses may be related to biological factors relevant to adults mating and laying eggs. In mesh-houses, development of eggs and 1st and 2nd instars and ecdysis of 3rd instars were completed. However, a mass of 3rd instars were dead at their early stage. The reason has not known yet. It is concluded that the mass death of 3rd instars would be the crux of mass-rearing of S. splendens. |
