Flight performance and metabolism of the moth Spodoptera frugiperda

Journal of Insect Physiology, 1971
Abstract Tethered moths were flown continuously for 4 to 7 hr in a sealed flight mill which allowed the trapping of CO2 and the recording of distance flown. The respiratory rate was approximately 10 cal/km per g or 30 cal/hr per g in flight, and 5 cal/hr per g at rest.

Characterization of the 20S proteasome of the lepidopteran, Spodoptera frugiperda

Biochimica et Biophysica Acta (BBA) - Proteins and Proteomics, 2019
Multiple complexes of 20S proteasomes with accessory factors play an essential role in proteolysis in eukaryotic cells. In this report, several forms of 20S proteasomes from extracts of Spodoptera frugiperda (Sf9) cells were separated using electrophoresis in a native polyacrylamide gel and examined for proteolytic activity in the gel and by Western ...
