Abstract
Stored grains are easily attacked by insects that
can get adapted to these artificial environments. In
Colombia, economic loses due to this fact are very
high. To prevent and combat these situations, it is
necessary to know the life cycle of the organisms
involved, their feeding habits and their most vulnerable
stages. Objective. To evaluate the life cycle of the
“cucarrón del maní“ (peanut beetle) Ulomoides
dermestoides COLEOPTERA: TENEBRIONIDAE
in three kinds of substrates. Methodology. The
damage level produced to the grains and the larvae
populations were determined in three substrates:
Corn, peanut and corn-peanut in a 1:1 proportion,
by the use of a design of random blocks with three
repetitions. Results. It was discovered that, from
the egg to the adult stage, the larvae take about
11.3 months. Besides, they pass through 11 instars
and also present mobile pupae. There were no big
differences found among the larvae in the different
substrates, nor in the level of damage caused to them.
Conclusion. The larvae of Ulomoides dermestoides
COLEOPTERA: TENEBRIONIDAE has a good
capability of adaptation and, therefore, they can infest
a considerable variety of stored grains.
