Table 3 Pupae production and sex separation efficiency by using the entire larval rearing units

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

Parameter Wol-unit IAEA-unit
Number of trays per rack 40 50
Estimated number of male pupae per traya 2459 7144
Estimated male pupae production per unit (105)b 0.98 3.57
Male pupae production per unit (105) 0.89 ± 0.02 3.16 ± 0.11
Female pupal contamination rate (%) 0.5 ± 0.1 a 0.9 ± 0.2 a
Male pupae production efficiency (%)c 90.9 ± 2.4 a 88.5 ± 3.0 a
  1. aEstimated number of male pupae per tray for Wol-tray and IAEA-tray was obtained from the top, middle and bottom section of larval rearing unit
  2. bEstimated male pupae production per unit was calculated as: (Number of trays per unit × Estimated number of male pupae per tray)
  3. cMale pupae production efficiency was calculated as: (Male pupae production per unit / Estimated male pupae production)
  4. Note: Within each row, values followed by same lowercase letters were not statistically different using Mann-Whitney U-test analysis (P > 0.05). All the data in the table were presented as Mean or (Mean ± SE)
