| Sumario: | Monalonion velezangeli is considered one of the
most harmful pests of avocado cv. Hass, as far as it attacks
vegetative buds, flowers and fruits during all the productive stages
of the crop. This situation is aggravated by the lack of knowledge
on insect preferences and their relationship with crop phenology.
As a contribution to the management of this insect, we studied
the relationship between plant phenology and the presence of
M. velezangeli, as well as its preferences across tree strata and
structures. Data were obtained from six orchards located in the
Colombian departments of Antioquia, Caldas and Quindío. After
randomly selecting 20 trees at each orchard, 12 branches were
marked on each tree, covering the combinations of the four cardinal
points with three plant strata (low, medium and high). During a
period of 12 months, each branch was monitored by recording
its phenological stage (vegetative, flowering and fruiting), the
number of individuals of M. velezangeli and the presence of
fresh damages on it. An analysis of variance determined that the
presence of the insect and its damage were more abundant on the
flowering and fruiting branches than on the vegetative ones, as
well as in the medium and upper strata of the trees. The damage
caused by M. velezangeli was observed to be significantly higher
in the reproductive structures (flowers and fruits) as compared to
the vegetative structures. |
