| Summary: | Salmwood (Cordia alliodora (Ruiz and Pav.) Oken) (Boraginaceae) is
used as a shade plant for cacao and coffee agroforestry systems in Colombia. In 2016
these trees were severely defoliated by insects on a farm in northeastern Colombia.
One hemipteran and one lepidopteran were found to be associated with the damage,
and one hymenopteran was found to parasitize the hemipteran. The hemipteran
was Edessa panamensis Fernandes von Doesburg and Greve (Pentatomidae), a new
record for Colombia and the first record of this species as a parasitoid host. A parasitoid
wasp, Neorileya albipes Girault (Eurytomidae), emerged from E. panamensis
eggs, and is recorded for the first time from Colombia. The lepidopteran feeding
on salmwood was Paridnea squamicosta (Walker) (Pyralidae). The larva takes refuge
from natural enemies in domatia on salmwood branches and emerges to feed
on leaves. The larval leaf consumption was estimated to be 134.1 cm2 with a larval
duration of 15.64 days; the pupal stage was 20.44 days. We also report for the first
time another host for this larva, the moncoro tree (Cordia gerascanthus L.), which
was affected to a lesser degree. Photographs of insect adults, larvae, eggs, and morphological
structures are provided. |
