Abstract: Alstonia scholaris R. Br. is commonly known as saitan ka jhad in Hindi belongs to the family Apocynaceae, is a classy and graceful evergreen tall tree grows up to 25m high which widely used as medicine and served as an important shade tree. Gall formation induced by psyllid herbivory Pauropsylla tuberculata, Crawf is of growing concern in A. Scholaris leaves infested with this insect developed an outgrowth called galls with change the leaf structure and alter physiological processes in the affected plant. A survey was conducted at Mewar University Rajasthan India Campus to access the incidence and severity from May to July 2020 and to study the total chlorophyll content and phenolic compound in the gall-infested leaves and uninfected viz (fresh leave, young gall, mature gall, and perforated gall) research survey depicted that incidence and severity of galls increase from May to July 2020 this is due to the onset of rainfall start in mid-June and gall require wet and warm temperature, activity of total chlorophyll were found to exhibit strong negative correlation with phenolic compound at different stages of gall development. The finding of this research can be enough to suggest that rainfall coupled with high-temperature increases galls incidence and severity and phenolic compound acts as a biochemical marker for foliar galls resistance in devil tree Alstonia scholaris.
