Abstract:

Four parasitoids of the passion fruit flower bud fly,
Dasiops inedulis were collected, i.e., a larva-pupa type
parasitoid, Utetes anastrephae (Viereck) (Hymenoptera:
Braconidae), and three pupal parasitoids, namely
Pachycrepoideus vindemmiae Rondani, Spalangia sp.
(Hymenoptera: Pteromalidae) and Aganaspis sp.
(Hymenoptera: Figitidae). In the field we observed a
species of Chrysopidae (Neuroptera) larva feeding on the
sentinel pupae of D. inedulis. We conducted experiments
on the efficiency of a toxic bait made from the bacteria Saccharopolyspora spinosa, as a new alternative for controlling D. inedulis on yellow passion fruit. This toxic bait maintained the injury levels below the conventional management used by farmers and the control plots in both study areas. A list of
natural enemies of D. inedulis was compiled by inspecting
passion fruit flower buds, using sentinel pupae, and
information taken from the literature. For the control of
D. inedulis, an integrated pest management strategy is
proposed that will allow the farmer to maintain D. inedulis
populations under control with different management
tools, i.e., natural enemies which can be incorporated
at different stages of development of D. inedulis, low
toxicity baits, recollection of flower buds with symptoms
of damage, monitoring with McPhail traps baited with
protein hydrolysate, thus intervening at different stages
the development breaking its life cycle
