A temperatura e o desenvolvimento larval de Chironomus sancticaroli (Diptera: Chironomidae)

Abstract

Development rate, survival and growth of a neotropical midge, Chironomus sancticaroli, were determined in laboratory at dillerent temperatures. The "lower thermal limit" is 12°C and the "thermal constant", characteristic for the species, varies Irom 140-144 day-degree. These results pointed out to a high development when compared with species 01 tempera te areas and permit to expect, for C. sancticaroli, 16-18 generations/year, in natural conditions.
