A field study was conducted to evaluate the effectiveness of bitter
melon oil at an average of 2 ml/L and Bifenthrin at a rate of 1 ml/L,
as well as the interaction between Bifenthrin + bitter melon oil at a
concentration of 1 ml/L and 2 ml/L of …
A field study was conducted to evaluate the effectiveness of bitter
melon oil at an average of 2 ml/L and Bifenthrin at a rate of 1 ml/L,
as well as the interaction between Bifenthrin + bitter melon oil at a
concentration of 1 ml/L and 2 ml/L of oil on adult and immature roles
and eggs of the two-spotted red mite Tetranychus urticae Koch
(Acari: Tetranychidae) on the okra plant Abelmoschus esculentus L
(Malvaceae).The results indicated that the highest mortality rate for
adult mites was when the treatment of the interaction between
Bifenthrin + cognac oil with the mentioned concentration and the
lowest mortality rate was when the control treatment (water only)
reached 1,181 and 2,654 mite /leaf, respectively. There are significant
differences between the mentioned treatments, and all treatments are
significantly excelled on the control treatment in reducing the number
density of adults. As for the non-adult roles, the results showed that
the highest average of the number density of larvae and nymphs
appeared in the control treatment and the lowest rate appeared in the
Bifenthrin + cognac oil treatment with a concentration of 1 ml / liter
for the pesticide and 2 ml / liter for the oil. It reached 4,305 and 2,117
caterpillars and nymphs/leaf. Also, the results indicated that there
were significant differences between all the mentioned treatments,
and all the treatments were significantly excelled on the control
treatment. The results showed that there were no significant
differences in reducing the number density of eggs between the
Bifenthrin pesticide treatment and the interaction treatment between
Bifenthrin + bitter melon oil, and indicated that the Bifenthrin
pesticide treatment was excelled on the bitter melon oil treatment. All
of the mentioned treatments were excelled on the control treatment in
reducing the number density of eggs, where the lowest number
density appeared in the treatment + Bifenthrin + bitter melon oil
during the time period of 21 days of treatment, and the highest number
density appeared in the control treatment during the same time period
mentioned, as it recorded 1.282 and 2.807 eggs. /Leaf respectively.
