dc.description.abstractThe present investigation on “Bio-diversity of major insect pests of mango and their bio-rational management” was carried out at Horticulture Farm, ARS, Banswara and Department of Entomology, Rajasthan College of Agriculture, MPUAT, Udaipur and five district of Southern Rajasthan during 2021-22 and 2022-23. The survey result revealed that the insect pests belonging to Hemiptera order showed maximum mean density and relative density. Shannon-Wiener index was maximum for Coleoptera followed by Hemiptera, which indicate that the order Coleoptera showed maximum evenness and less diversity. Simpson index was higher for Thysanoptera, Diptera and Orthoptera, which showed that the greater the value, the greater the diversity of insect pests of mango during both the years. The associated natural enemies belonging to Hymenoptera order showed maximum mean density and relative density, whereas Neuroptera and Mantodea order showed least mean density and relative density during both the years. Shannon- Wiener index was higher for Hymenoptera and Coleoptera, whereas minimum for Hemiptera and Neuroptera. Simpson index was maximum for Hemiptera, which showed that the greater the value, the greater the diversity of sample. The COXI gene sequences of mango hopper from Rajasthan, U.P. and Maharashtra regions demonstrated a noteworthy 99 to 100% similarity to sequences from various parts of India. The spray of Lambda cyhalothrin 5 EC at 0.50 ml/l gave the best results with highest mean reduction of mango hopper population at 1st, 3rd and 7th days after spray, while Buprofezin 25 EC at 1.25 ml/l was found superior at 14th days after spray during both the years. The next order of effectiveness of treatment was Metarhizium anisopliae 1.15% WP > Verticillium lecanii 1.15% WP > Beauveria bassiana 1.15% WP > Azadirachtin 10000 PPM > Dashparni @ 50 ml/l against mango hopper during both the years
