Effect of Botanical Insecticides on Coffee Berry Borer, Hypothenemus hampei (Ferrari) (Coleoptera : Scolytidae)

In a laboratory study with eight botanicals against the coffee berry borer, Hypothenemus hampei (F.) showed that neem oil (3%) was superior (78.67%) to others in bringing about berry borer mortality, followed by TNAU NO 60 EC A 3%, TNAU NO 60 EC (3%) and NSKE 5%. In the field studies, NSKE 5% was superior to others botanicals and was followed by TNAU NO 60 EC A 3%, TNAU NO 60 EC C 3% and neem oil 3%. It was concluded that the variation noticed in effectiveness of the botanicals in the laboratory and field experiments may be due to the rate of photodegradation.
