A pilot study for area-wide management of fruit fly in mango for the central gangetic plain.
The management of fruit flies (Diptera: Tephritidae) in mango orchards by the male annihilation technique (MAT) is considered beneficial when deployed in a wide area involving many individual farms. This experiment assessed the patterns of invasion of flies when para-pheromone and insecticide-soaked wooden blocks were used in 24 hectares area of mango orchard at Central Institute of Subtropical Horticulture, Lucknow (India). The MAT greatly reduced the fly population in the inner parts of the protected area, while higher population was found in the outer areas. Even after twenty weeks, the population in the inner core remained at a lower level. It was concluded that MAT is efficient to protect over large areas, subject to uniform distribution of blocks. However, implementation of techniques at village level will require sound understanding of village needs, ecology and social aspects.
