Abstract:
An experiment was conducted under field conditions at Anand Agricultural University, Anand during December, 2021 to December, 2022. The incidence of psyllids started from the 50th SMW i.e., 2nd week of December, 2021. Initially, it’s population was low (6.25 psyllids per 10 cm twig per plant) and attained peak level of psyllids population (40.15 psyllids per 10 cm twig per plant) during the 10th SMW i.e., 2th week of March, 2022. The lowest population of psyllids were recorded at 38th SMW i.e., 4th week of September, 2022 (0.56 psyllids per 10 cm twig per plant). While, the psyllids population gradually increased from the 40th SMW i.e., 2nd week of October, 2022 (0.92 psyllids per 10cm twig per plant) to the 49th SMW i.e., 2nd week of December, 2022 (5.45 psyllids per 10cm twig per plant). The higher incidence of this pest was found during the fourth week of December, 2021 to second week of July, 2022 (52nd SMW to 28th SMW). Psyllids population showed significantly positive correlated with the evaporation and bright sunshine hours. While, evening relative humidity, morning relative humidity and evening vapor pressure were found significantly negative correlated with the psyllid’s population.
