2. Seasonal abundance of fruit piercing moths
The seasonal abundance of trapped adult
FPM (all species) among the fruit plantings is
illustrated in Figure 3. Despite the differences in
numbers of trapped moths, two general annual
periods of adult activity are apparent. Subsequent
samples taken after December 2003 show a decline
in moth activity from the end of the year peak. The
next peak of moth activity started to occur in April.
In the longkong and pomelo plantings the moth
flight began to decline in July, whereas in citrus
moth activity dropped in August and September.
Between October and November the number of
moths trapped started to increase again. This
increase was much more pronounced in the citrus
planting.
