Descrizione Seasonal incidence, susceptibility and management of guava fruit fly
Experiment was carried out at FRS, Sakkar baug, CoH, JAU, Junagadh during the year 2022-23. The fruit fly population was recorded from the 23rd to the 52nd SMW. The peak incidence of fruit fly was recorded at 35th SMW which was 865.13 fruit flies per trap. On the other hand, the lowest population of fruit fly (10.00 fruit flies/trap) was recorded at 52nd SMW. Maximum activity of fruit fly was remained throughout August month with 800.31 fruit flies per trap and the minimum activity of fruit fly was observed during the December month with 21.12 fruit flies per trap. Fruit fly had a highly significant positive correlation with evening humidity (r = 0.670), morning humidity (r = 0.669) and minimum temperature (r = 0.522). While, wind speed (r = 0.216) and rainfall (r = 0.293) were also found positively correlated but it was non-significant to the fruit fly population. Temperature fluctuation (r = -0.696), relative humidity fluctuation (r = -0.616), bright sunshine hours (r = -0.486) and evaporation (r = -0.483) had a highly significant negative correlation with fruit fly population.
