Abstract
Jassid is one of the most serious pests and a threat to okra
production. An experiment was conducted in the Entomology Field Laboratory,
Department of Entomology, Faculty of Agriculture, Bangladesh Agricultural
University; Mymensingh related to Management of okra jassid (Amrasca
devastans) using bio-rational and conventional insecticides using 6
treatments Pymetrozine, Buprofezin, Lufenuron, Chorpyrifos, Neem oil including
control. The experiment was laid out in a Randomized Complete Block Design
(RCBD) with three replications. A total of 3 sprays were given at 10 days
interval. The effectiveness of selected insecticides was evaluated based on
different parameters vz. number of nymph/plant, number of adult/plant, total number
of curled leaf/plot, fruit weight and no. of fruits and yield. It was found
that all the treatments were effective in controlling jassid population than
control plants. But, the best results obtained from Pymetrozine treated plants
followed by Buprofezin, Lufenuron, Neem oil in comparision to control in terms
of fruit infestation. The results also indicated that highest marketable fruit
yield (15 t ha-1) was obtained from Pymetrozine treated plots
followed by Buprofezin (13.45 t ha-1) and Neem oil (12.52 t ha-1).
The lowest yield was (7.26 t ha-1) found in control
plots compared to other treated plots. Therefore, it might be concluded that
these botanicals, IGR’s and chemical insecticides could be used to reduce the
damage caused by okra jassid and Pymetrozine might be best for successful for
sustainable management of jassid.
