Abstract

Information on the life history of the snail-killing fly, Dictya montana Steyskal 1954 is presented. The mean duration of the immature stages at 26°C was 21.56 ± 2.60 days and larvae were voracious predators with a mean predation capacity of 16.60 ± 1.76 snails. The survival period of unfed neonate larvae appeared to be temperature dependent and ranged from 2 to 29 days at 26°C and 4°C respectively. However, storage of freshly laid eggs at −20°C for 7 days did not yield viable larvae. For the first time, the phenology of D. montana is detailed and its biocontrol potential against snail-borne diseases is discussed.
