Effect of weather parameters on seasonal incidence of fruit flies in mango (Mangifera indica L.)

Among the different varieties grown Dashehari recorded a minimum trap catch of 11.50 adult fruit flies (20^th standard week) and Totapuri a maximum of 104.25 trap catch (21^st SW) followed by Suvarnarekha a trap catches of 70.25 (19^th SW) during their peak periods. The mean trap catch of all experimental SW was also highest in the variety Totapuri (51.43) followed by Suvarnarekha (42.00) while the lowest mean trap catches (6.69) was recorded in the Dashehari. The incidence of fruit flies had a high significant and positive correlation with both maximum and minimum temperature and significant negative correlation with morning relative humidity when monitored during the fruit development and maturity period. The mean number of maggot emergence per fruit showed highest values in Suvarnarekha (6.40) followed by Totapuri (6.10) and lowest in Langra (1.07).
