得克萨斯州立学院试验站在生物气候室内使棉铃虫虫蛹的潜育期经受不同的光照期和不同的温度,并将潜育终止期所需的日数记录下来。潜育终止期受温度的影响很大,受光照期的影响则较小。潜育终止期所需日数与温度成负相关。棉铃虫在育虫室内是按照普通昼长和普通温度饲养的。潜育的蛹都在育虫 The Texas State College experimental station subjects the incubation period of the bollworm pupae to different light periods and different temperatures within the bioclimatic chamber and records the number of days required for the deadline. The end of incubation period is greatly affected by the temperature, but less affected by the light period. The number of days required to terminate the incubation period is negatively correlated with temperature. The cotton bollworm is kept in the houseworm indoor according to ordinary day length and ordinary temperature. Litter pups are insects
