  1. Eggs were collected from small rearing cages, and either hatched immediately or dried before hatching into larval mass-rearing trays (100 × 60 × 3 cm), and then reared to adulthood. Results of a t test comparison between fresh and dried egg batches are presented
  2. Within each egg type all parameters were found not to be significantly different from each other (t test) (P > 0.05)
  3. PR pupation rate as a proportion of eggs, ER emergence rate as a proportion of total pupae, IR insemination rate as a proportion of all female adults, F fecundity (mean number of eggs per treatment), WL wing length
