Influence of environmental factors on the wandering phase and pupariation in stable fly, Stomoxys calcitrans, larvae

Linda J McPheron , Alberto B Broce
ABSTRACT
"Components of the wandering phase of mature stable fly (Stomoxys calcitrans L. (Diptera:Muscidae) larvae were examined. The mean lenght of the wandering pase was estimated to be 10.6+/-3.5 h. In a factorial experiment in which wandering lavae were allwed to pupate in media with three levels of moisture, temperature, and light, the mean time to 50% pupariation was delayed and the rate of pupariation was lowest at high moisture levels, but this latter effect was seen only at the moderate light level. Pupae in media with higher moisture contents had significantly higher fresh weights. However, none of the three factors affected dry weight of pupae. A significant interaction was observed between the effects of miosture and temperature on survival; only at highest moisture content and at the highest temperature did a significant decrease in survival occur. In a separate experiment, density was found to have no effect on mean time to 50% pupariation or the rate of pupariation. Puparium formation appeared to be random under a LD 16:8 photocycle, showing no apparent circadian rhyhm."
