Abstract:
The study was carried out at
two experimental farms in Ismailia
Governorate, Egypt, during season of 2015
and 2016. GF-120 (Conserve® 0.024% CB)
was selected in this study to evaluate its
efficacy for controlling the peach fruit fly,
Bactrocera zonata (Saunders) and the
Mediterranean fruit fly, Ceratitis capitata
(Wied.), on mango fruits by using partial
bait spray and spots method. GF-120 was
used as low environmental impact method
and new way to control B. zonata and
C. capitata, compared with malathion 57%,
as traditional insecticide. During both
seasons, data revealed that the number of
C. capitata captured weekly from different
treatments and untreated plots was higher
than the number of B. zonata captured in
both seasons of experiment. Data revealed
that the number males of B. zonata and
C. capitata captured weekly from sticky
traps were lower in trees treated with GF-
120 than malathion and untreated plots. In
the farm of Faculty of Agriculture, Suez
Canal University, the lowest percentages of
infestation of both dropping and setting
fruits per tree were recorded in plots treated
with GF120 (spots), with an average of
25.14 and 17.022% for dropping fruits and
2.2 and 2.0% for setting fruits for 2015 and
2016 season, respectively. Data indicated
that the all tested formulation under field
condition caused significant reduction in the
rate of infestation from 54.92 to 81.79 for
both dropping and setting fruits. The lowest
percentages of infestations in the private
farm of both dropping and setting fruits per
tree were recorded in GF-120 (spray
treatment), with an average of 20.0, 12.12
for dropping fruits and 3.4 and 4.0 for setting fruits for 2015 and 2016 seasons,
respectively.
