Sweet Granadilla (Passiflora ligularis) is a crop of great importance for Ecuador because it has agro export
prospects in countries like Colombia have conducted research to learn pests affecting it; in Ecuador they have not
executed these activities why there are no records of the pest that most commonly attack plants of Passiflora. This
study aimed to determine the severity of the Lonchaeidae species attack this crop, and identify the causative agent.
The present study was carried out in the province of Tungurahua, Baños canton, parish Illuchi. 15 plants were
selected on five sites, 4 reviews spaced 30 days, in each sample, 50 flowers/plants/site were considered. In order to
obtain adult specimens, adequate samples were collected from the field, and maintained in the laboratory condition
for the identification of imagos. Totally 9766 samples were collected and evaluated, out of which 20.51% are
flowering botton affected by plague and 39.76 % of the flowers were destroyed by the Dasiops larvae attack the
ovary of flower bud. Dasiops curubae and Dasiops brevicornis are new record of parasite species for Ecuador and
Passiflora ligularis is also a new record of host species.
