| description | Aphis spiraecola Patch. (Hemiptera: Aphididae)
is a key pest of citrus clementines. This aphid colonizes
tender clementine shoots in the spring and causes
important economic losses. A complex of predators preys
on A. spiraecola colonies but does not result in satisfactory
control. To disentangle the reasons for this failure, we investigated
the effect of predators on A. spiraecola colonies
and damage over a 3-year period. A. spiraecola colonies
were tracked every 48–72 h from the period of aphid
colonization until the colony declined or disappeared. The
number of aphids, their stage and the presence of predators
were recorded in each colony. Different life parameters of
A. spiraecola colonies (maximum number of aphids,
longevity and colony phenology) varied among the orchards
over 3 years. Predators attacked one-third of the
colonies, and this did not significantly differ among orchards
for the years studied. The maximum number of
aphids and longevity of A. spiraecola colonies were not
related to the ratio of colonies attacked by predators but
were negatively correlated with the time of their first attack.
More importantly, the percentage of shoots occupied
by A. spiraecola remained below or close to the intervention
threshold when colonies were attacked prior to *200
degree days from the beginning of the aphid colonization.
These results suggest that (1) the presence of predators at
the beginning of the season should be considered to develop
new intervention thresholds and (2) biological control
programs should promote the early presence of
predators in clementine orchards. |
