Table 1 Effects of Aedes albopictus larval rearing densities on the pupae production and larval survival at different pupation times when using the Wol-tray or the IAEA-tray

From: Establishment of a medium-scale mosquito facility: optimization of the larval mass-rearing unit for Aedes albopictus (Diptera: Culicidae)

  1. Abbreviations: PP pupae production, MPP male pupae production, M% percentage of male pupae in PP
  2. aLarval survival was calculated as: (Total number of pupae collected + Residual number of larvae after sex separation) / (Estimated number of larvae per tray)
  3. Note: Within each column, values followed by different lowercase or capital letters were statistically different using ANOVA analysis and Tukey post-hoc test (P < 0.05)
