BERGO, Eduardo Sterlino; BURALLI, Geraldo Magela; SANTOS, Jair Licio Ferreira and GURGEL, Sergio Mello. Evaluation of the larval development of Anopheles darlingi (Diptera - Culicidae) raised in the laboratory on different diets. Rev. Saúde Pública [online]. 1990, vol.24, n.2, pp. 95-100. ISSN 0034-8910. http://dx.doi.org/10.1590/S0034-89101990000200003.
Three diets for A. darlingi larvae were tested in order to arrive at the following parameters indicative of development in this phase: length of time, both for overall as for each stage of evolution and daily and total stage-survival. A methodology which combined two vital statistical methods of analysis, adjusted to the study of populations under laboratory conditions, was used for determining these parameters. The length of time for overall and for each stage of, evolution were graphically assessed on the basis of trend curves of colony median stages, in sequential surveys. Values for the total and the daily stage-survival were stimated from survival tables. Results permitted the selection of the most adequate diet for the larval development as that composed of one part of fish flour to two parts of bread flour and two parts of a heat germ, giving an average length of 12.9 days between the first larval stage and the emergent adult. Total survival rate was of 95%.
