为观察丝光绿蝇室内连续饲养的各代蛹形态变化,将丝光绿蝇引入室内,采用人工配制的幼虫饲料在室内进行连续饲养,分别随机挑取室内第2～5代1日龄蛹,及时称量蛹重,测量蛹长。结果发现,第2～5代蛹长（x±s）分别为（mm）:6.85±0.30,7.13±0.21,7.17±0.22,6.79±0.22;蛹重分别为（g）:0.0268±0.0032,0.0294±0.0018,0.029±0.002,0.026±0.003。经t检验,第3、4代间蛹重、蛹长均无显著性差异,但蛹重、蛹长都显著性大于第2代及第5代;第2、5代间在蛹重及蛹长均无统计学差异。
In order to observe the morphological changes of pupae cultured continuously in the laboratory, the silky green flies were introduced indoors, and the larvae feed was manually fed indoors. Weigh the pupal weight and measure pupal length. The results showed that the pupal length (x ± s) of 2nd to 5th generation were (mm): 6.85 ± 0.30, 7.13 ± 0.21, 7.17 ± 0.22 and 6.79 ± 0.22, respectively. The pupa weights were 0.0268 ± 0.0032 and 0.0294 ± 0.0018, 0.029 ± 0.002, 0.026 ± 0.003. There was no significant difference in pupal weight and pupal length between the 3rd and 4th generation after t-test, but the pupal weight and pupal length were significantly greater than those of the 2nd and 5th generation. The pupal weight and pupal There was no statistical difference between them.
