Abstract:

The study on seasonal incidence of summer okra as influenced by weather parameters on aphid, lady bird beetle and syrphid fly showed its peak presence during 16th MW and maximum population of chyrsopa during 17th MW, predatory spider during 20th MW. The correlation studies indicated that aphid showed positively significant correlation with bright sunshine and negatively significant correlation with rainy days. While lady bird beetle, chrysopa and predatory spider showed positively significant correlation with maximum temperature, minimum temperature, evaporation and negatively significant correlation with morning RH and evening RH. Whereas syrphid fly revealed non- significant correlation. The equations of linear regression was set of aphid, lady bird beetle, chrysopa and predatory spider population by working out regression coefficient (b) and constant (a) but was not possible in syrphid fly population as the impact of all weather parameters were found non-significant. The multiple regression equation fitted were worked out and the coefficient of determination (R2) mostly showed higher indication, hence the predictions and forewarning of the aphid and natural enemies population by using weather parameters were reliable.
