Experiment on the management of mango hopper, Amritodus atkinsoni Leth. (Homoptera: Cicadellidae) was conducted in the laboratory and field Department of Entomology, Bangladesh Agricultural University, Mymensingh during January to May 2007. Three botanical pesticides namely Neem oil, Mahogoni oil and Karanja oil and a chemical pesticide, cythrin 10 EC and a net barrier as a mechanical control were evaluated in controlling mango hopper. Cythrin 0.2% was found to be most effective in controlling mango hopper but percentage of fruit set was relatively lower than cythrin 0.10% and 0.15%. Among the botanicals, Neem oil (3%) showed higher efficacy while Mahogoni oil (1%) was least effective. Observation on extent of hopper damage during flowering and fruit setting period of mango showed that 80-90% fruit damage. Net barrier protected the inflorescence from the attack of mango hopper but failed to produce fruits. The effect of different control approaches in the control of mango hopper and activities of pollinators are discussed.
