Studies on the succession and incidence of different shoot gall maker (Betousa stylophora) on aonla was studied at College of Agriculture, RVSKVV, Gwalior. The observations were recorded at weekly interval in the field conditions starting from the first week of October at different stages of plant growth up to fourth week or last week of May, on the three randomly selected trees, on the incidence of various shoot gall maker (Betousa stylophora). The highest number of gall (9.7/ plant) and branch infestation (73.4%) due to shoot gall maker was recorded in the 8 standard week (19-25 Feb.) and 14 standard weeks (02-08 April) respectively, when the average minimum and maximum temperature, relative humidity and rainfall observed were 11.7*0 to 29.2'C. 40.1'C to 22.8'C. 87.0% to 50.1% and 0.0 - 0.0 mm. respectively. The correlation studies reveal a significant and positive correlation between population of shoot gall maker (r=0.100) with average temperature. Whereas, correlation coefficient was found no significant between average relative humidity and populations of shoot gall maker.
