ABSTRACT

The population dynamics of the peach fruit fly, Bactrocera zonata (Saunders) and oriental fruit fly Bactrocera dorsalis (Hendel) were monitored from January to December 2018 in guava orchards of the Sindh Pakistan. The investigations were done at different localities of Hyderabad and Larkana using Steiner type traps incorporated with methyl eugenol. The trap catches of B. zonata and B. dorsalis in both climatic zones shown a similar pattern during the study with a major peak in August in off seasoned guava. Whereas decreased population of Bactrocera flies were obtained in the month of January in Larkana (16.5±1.18, 12.9±1.47) and Hyderabad (19.3±1.28,13.4±1.39) regions, respectively. The abundance of fruit flies showed a significant correlation with temperature and slight negative relativity with humidity. The result suggests that high temperature enhances the fruit flies activity in connection with the availability of fruiting parts. The present investigations would be helpful to attain effective integrated pest management campaign in guava orchards.
