Abstract:
A survey was carried out at different locations in Gwalior at fortnightly intervals during the year 2021-2022 to investigate the distributional patterns, population dynamics and infestation of apical twig gall maker on aonla. During the distribution studies the infestation level of population dynamics of gall pest was recorded from November 2021 to April 2022. Significant variations in the population dynamics and infestation level were recorded. In the findings, it was revealed that the infestation level ranged from 8.33% to 48.61% among different locations. The population dynamics studies in the present findings revealed that the population count ranged from 0.43 to 10.71 galls/plant. The maximum infestation was noted in Tavopan (48.61%) region which was significantly higher than the other locations while the minimum infestation was found to be in the Krishi Colony (8.33%) location which was significantly lowest among all the locations. The highest gall population was found to be in the Tapovan location (10.71 galls/plant) which was significantly higher than all the other locations i.e. Government nursery (7.99 galls/plant), Jamuna bagh (4.53 galls/plant), Kedarpur-1 (7.07 galls/plant), Kedarpur-2 (5.79 galls/plant), K.V.K (8.40 galls/plant) and Krishi Colony (0.43 galls/plant) which recorded the lowest population significantly.
