BARI identifies invasive insect pest Whitefly

Our Correspondent GAZIPUR, Jan 13: The scientists of the Entomology Division of Bangladesh Agricultural Research Institute (BARI) for the first identified the invasive insect pest Rugose Spiraling Whitefly (Aleurodicus rugioperculatus Martin) in Bangladesh. Chief Scientific Officer (CSO) of the Entomology Division of BARI Dr. Debashish Sarker advised the farmers not to spray toxic chemical insecticides indiscriminately as this practice would kill the beneficial insects which naturally control this pest, resulting the pest problem to be more severe. Scientist Debashish suggests spraying different bio-pesticides, especially Neem- based bio-pesticides e.g. Fytomax, Bioneem plus etc. to control this whitefly. Scientists observed this species, which is a new exotic Whitefly, in coconut trees at Regional Agricultural Research Station (RARS), BARI, Jashore, in April 2019, which was the first report of its occurrence in Bangladesh. By this time, BARI Entomologists have recorded this pest attack in coconut trees from Magura, Pabna, Panchagarh and Gazipur districts. Although the pest is native to Central America, in 2016 it was reported from India infesting coconut trees. Worldwide, this whitefly has been reported on more than 60 plant species, but it prefers coconut and other palm trees, banana etc. However, farmers should not be panicked due to infestation of this pest. In case of severe infestation, less toxic new generation chemical insecticides can be sprayed with the consultation of local agricultural extension personnel.
