Abstract
Tomato borer, Tuta absoluta is a polyphytophagous species with
highly reproductive potential and development on numerous cultivations, mainly
belonging to Solanaceae crops, especially to tomato crop, Lycopersicon esculentum.
It caused serious damages and yield losses of tomato crops due leaf
mines and fruit infestations reach to 100% yield loss in tomato crops in both
open-field and greenhouse conditions. Therefore, this study was carried out for
assessing some biological control tactics using parasitoid, sex pheromone and
bio-products against this pest on tomato crop. The obtained results showed that
the releasing of 60 cards of Trichogramma euproctidis /feddan
differed significantly comparing to the other rates of Trichogramma in
dead larvae numbers of T. absoluta. So that, the releasing of 60 cards
of Tr. euproctidis /feddan is the best rate that had been recorded
by increasing the reduction of T. absoluta eggs and larvae than other
treatments. The obtained data indicated that Tuta 100N baited with3 mg/
dispenser of (E,Z,Z) -3,8,11-Tetradecatrienyl acetate caught relatively high
numbers of males than other investigated sexual pheromone traps. Additionally,
the attractiveness longevity for the tested commercial sexual pheromone lures
was powerful
up to 30 days. In IPM program (treated field), the resulted a decreasing of
tomato borer, T. absoluta mines according to reduce the mean numbers of
larvae/ leaf through summer season, 2023. Abundance of T. absoluta eggs,
larvae, mines and moths remained low populations in treated program (IPM
tactics) than control field throughout summer season, 2023. Three peaks were
noticed in control plot while two peaks were recorded in the treated field.
Accordingly, this work was conducted by using of biocontrol agents including
orange oil (d-Limonene), a mixture of Capsicum oleoresin extract
+garlic oil+ canola oil, a mixture of citronella oil + jasmine oil + mineral
oil, Bacillus thuringiensis subsp. Aizawai and azadirachtin helps
in reducing T. absoluta infestations, thus it was essential in our study
to explore the efficiency of a combination between some parasitoids and using
of sexual-pheromone traps altogether to put the most suitable elements in
tomato borer management plan.
