TWD : Glossary: adenotrophic viviparity

Title

adenotrophic viviparity

Definition

A method of viviparous reproduction restricted to pupiparous Diptera. The egg hatches inside the mother and the larva feeds on uterine secretions produced by the mother. Pupation occurs shortly after larviposition (Gordh and Headrick 2001, Leak 1999). Reproduction in which the female gives birth to a larva which developed and has been nourished within the mother’s uterus (Leak 1999). The production of live offspring, where eggs are retained within the female oviduct until the larvae are mature at which stage they are laid and immediately pupate (Wall and Shearer 1997). A phenomenon in certain insects whereby the larvae are retained in the parent’s body after hatching, develop by feeding on ‘uterine’ secretions, moult twice and are finally deposited in a mature state ready for pupation (Leftwich 1976). See ‘gestation’, ‘larviposition’, ‘larviparous’, ‘viviparous’.
