Abstract: Surveys conducted to understand the diversity of phytophagous insects infesting Tabernaemontana divaricata in Karnataka revealed the occurrence of 13 species of phytophagous insects which includes 4 species of defoliators and 9 species of sap suckers. Among the insect pests, the infestation of Parotis marginata was found to be severe, affecting health and even causing death of plants, requiring cultural as well as plant protection management strategies.
