Fisher's test was used to investigate differences provoked by treatment with acetazolamide between the observations presenting pH⩽6.0 and a group formed by all other observations (with pH>6.0). P<0.05 was considered significant
TM, thoracic midgut; AM, abdominal midgut; ACZ, with acetazolamide; No ACZ,without acetazolamide
