Seasonal abundance of rose pests in relation to weather parameters
SD Chaudhari and Sushil Kumar
The study based on seasonal incidence of rose pest was carried out at Khambhaliya, in Nasari district of Gujarat during 2018-2020. Seasonal incidence of rose pests indicated highest activity of thrips during 19th SMW. Aphid and bud borerlarvae remained more active during 6-7th SMW. Higher activity of Castor semilooper was noticed during 24th SMW while, higher activity period of Tussock moth was observed during 40th SMW. Thrips population exhibited positive correlation with temperature (maximum and average) and negative with RH and rainfall. Aphid was negatively influenced by minimum temperature, RH and rainfall. Castor semilooper was directly influenced by temperature while, Tussock moth was directly associated with RH. Bud borer was negatively influenced by temperature (minimum and average) and RH.
