OVIPOSITION DETERRENCE OF FRUIT FLY IN TREATED MANGOES WITH ANT CUES AND FUNGUS B. BASSIANA

Abstract

Bacterocera zonata is a very serious pest of fruit crops especially mangoes over the globe. The present study was conducted to observe oviposition deterrence in B. zonata under lab conditions. Mangoes (Desi, Chaunsa and Anwar Ratool) were treated with ant cues and entomopathogenic Beauveria bassiana. Oviposition deterrence was recorded when nonspecific and variety specific (Chaunsa, Anwar Ratol) mangoes were treated with ant cues and B. bassiana at different intervals (exposure to 4 days). It showed that the mean number of oviposition punctures tend to increase with time. Minimum fruits puncture was found at day 1 in B. bassiana treated mangoes, while at 4th day, maximum number of punctures were observed in untreated mangoes. B. bassiana treated mangoes showed minimum number of punctures than ant cues and untreated mangoes were observed with highest number of punctures.
