POPULATION DYNAMICS OF FRUIT FLIES (Diptera: Tephritidae) IN GUAVA ORCHARD IN JABOTICABAL – SP

Abstract

ABSTRACT: The importance about monitoring and population dynamics of fruit flies species (Diptera: Tephritidae) influence substantially in decision and on the choice of control methods recommended by Integrated Pest Management. In this way, the goals of this research were monitor and analyze the population dynamics of adults of fruit flies and your correlation with the meteorological elements in guava orchard in Jaboticabal – SP. The research was conducted in guava orchard between October 2007 and January 2009. The population monitoring of adults of fruit flies was performed with five Mc Phail® traps, with food bait consisting commercial product Moscatex® (3%) and sweet guava juice (50%). The population density of fruit flies was analyzed in histograms and correlated with the meteorological dates maximum temperature (°C), minimum temperature (°C), mean temperature (°C), relative humidity (%) and cumulative rain precipitation (mm). The results showed that C. capitata had lower prevalence when compared to the genus Anastrepha, with higher population density from October until December 2007 and reaches the top in October and November 2007. There were not significant correlations between the population of fruit flies and meteorological elements.   KEY-WORDS: Anastrepha spp., Ceratitis capitata, integrated pest management.
