Cost effective trapping of fruit flies in mango

Field experiments were conducted to evaluate cost effective management strategies against fruit flies in mango during 2009–10 to 2012–13 in south Gujarat. Installing the plastic bottle trap containing wooden block (5 x 5 x 1 cm) impregnated with mixture of ethyl alcohol, methyl eugenol and DDVP in ratio of 6: 4: 1 @10 traps/ha collects maximum number of male fruit flies (22823/ha); this resulted in lowest fruit fly damage (4.45%) and maximum cost benefit ratio (1: 76.17). The glass (wide mouth) bottle trap is the next best containing 0.1% methyl eugenol and 0.1% DDVP followed by the Nauroji traps.
