Population dynamics of fruit fly species caught through methyl eugenol traps at different locations of Kanpur, Central U.P.

Studies on population dynamics of different fruit flies, by using locally made methyl eugenol (ME) traps were conducted at five locations of Kanpur district, (U.P.). The incidence of fruit flies was correlated with weather data. Three species viz. Bactrocera dorsalis (hendel), B. zonata (sounders) and B. correcta (Bezzi) were captured in the Me Traps, of which B. correcta was predominant followed by B. zonata and B. dorsalis. On population of B. correcta, temperature had a positive correlation at three places viz. horticulture orchard, vegetable farm and IIPR while at two places it had negative correlation (r = -0.034 and 0.2811) i.e. at insectary and Vishnupuri, respectively. Relative humidity was negatively correlated at four locations while it showed positive correlation at IIPR (r = 0.273). Rainfall had a positive correlation with catches of B. correcta at three locations while it showed positive correlation at two places. B.zonata and B. dorsalis had a positive correlation with temperature mostly.
