The experiment was carried out from April to May, 2011 at the laboratory of Mennonite Central Committee Bangladesh in Bogra district to know the efficacy of different soil amendments to control cucurbit fruit fly (CFF) Bactrocera cucurbitae. Seven treatments viz. Control (untreated), Dursban 20EC (@ 10 l ha-1), Furadan 3G (@ 10 kg ha-1), Neem oil cake (@ 1500 kg ha-1), Mustard oil cake (@ 1500 kg ha-1), Tricho compost (@ 2500 kg ha-1) and poultry refuse (@ 1500 kg ha-1) were used in the experiment and each treatment was replicated thrice. A similar effectiveness was found with the use of Dursban 20EC (@ 10 l ha-1), Furadan 3G (@ 10 kg ha-1) and poultry refuse (@ 1500 kg ha-1) for controlling of puparium. The experimental findings indicated that the use of poultry refuse (@ 1500 kg ha-1) in soil is a non-chemical way and could be a good practice in destroying the puparia of cucurbit fruit fly effectively for the bitter gourd farmers to manage the menace of fruit fly.

This experiment was conducted at Birganj Upazilla under Dinajpur district during 2008-2009 to know the effects of different organic components on the incidence of insect pest and diseases of eggplant. There were six treatments viz. use of chemical fertilizers (@ recommended dose), poultry refuse (@ 80 g pit-1), mustard oil cake (@ 80 g pit-1), vermi-compost (@ 200 g pit-1), cow-dung (@ 500 g pit-1) and Trichoderma (@ 2 g pit-1). Eggplant was selected as test crop. The plants were attacked by Phomopsis, bacterial wilt and root knot diseases in different treatments, but statistically there were no significant differences. The highest plant height (cm), number of flower plant-1 and yield was performed by the treatment use of Poultry Refuses (@ 80 g pit-1). The highest number of branching plant-1 was found in treatment use of Poultry Refuses (@ 80 g pit-1) and use of vermi-compost (@ 200 g pit-1).
