Surveillance on Population Dynamics and Fruits Infestation of Tephritid Fruit Flies (Diptera: Tephritidae) in Mango (Mangifera indica L.) Orchards of Faisalabad, Pakistan
Fruit flies (Diptera: Tephritidae) are amongst the world's worst pests of fruits that cause enormous losses in orchards. Due to their economic importance, fruit flies are severe pests of Mango Mangifera indica L. fruit, and their monitoring and infestation estimation are essential in order to formulate integrated pest management program. For practical field implementation, two variables such as flies per trap per weak were monitored by installation of Steiner traps hung on tree baited with Methyl eugenol attractant and percent fruit infestation through fruit host samplings. Surveillance for flies per trap was done each week by counting trap catches, recording and removing any flies that have been collected in traps and identifying the species. The percentage of fly infestation for mango fruit was examined by randomly analyzing a total of 100 fruits and observing number of fruits showing fruit fly oviposition or injury marks.
