The no preference for feeding of Epicauta in different species of passion fruit in free choice and no choice tests was evaluated under laboratory conditions. It was verified the best density of insects that provides the discrimination of resistance degrees. P. setacea, P. alata, P. edulis, P. cincinnata and P. laurifólia were evaluated. For the tests with and without possibility of choice, the preference for no feeding was evaluated through the attractiveness, where the number of insects attracted by species in Petri dishes was counted. The species P. laurifolia e P. alata had been resistant to E. atomaria, expressing the type of resistance of no preference for feeding. The densities of E. atomaria that better discriminated the species of passion fruit are three and five (test with and without choice) and two (test without possibility of choice) P. edulis, P. setacea e P. cincinnata are susceptible to E. atomaria.
