Abstract
Effect of different food plants on the development and biotic potential of the coconut white grab, Leucopholis coneophora was studied in specially designed field cages. Three-day-old first instar grubs were Individually reared upto adult stage on coconut seedlings, cassava, cacao and wild sunn-hemp. Duration of different stages of L. coneophora, size and body weight, percentage survival, fecundity and vlability of eggs were recorded. The duration of devetopioeat was least In cassava and coconut followed by those in cacao and wild sunn-hemp. The observations indicated that cassava and coconut were more,: favourable hosts of L. coneophora. A higher build up of pest population is, hence, likely In coconut ' gardens In which cassava is grown as an intercrop.
