Schematic representation of P. fastuosa infestation to Tasar plants. Each column represents the experimental sites (Site I covering 4-year-old plants; Site II: 4–8; Site III: > 8) from where three equidistant equal-sized subplots with an equal number of plants (n = 30) were surveyed for three consecutive years (2017 to 2019). Subplot-wise pest infestations within a site, and year-wise pest infestations within a plant-age group were found to be statistically non-significant; however, when the data were compared between plant-age groups (among the sites), a significant result of pest infestation (p = 0.02732) was observed
