Natural ecosystem services such as soil formation, nutrient cycling, pollination of plants and biological control of pests are provided by beneficial insects. But in present scenario due to heavy and indiscriminate use of chemicals decrease the diversity of these insects. Hence conservation point of view study was conducted to survey the diversity of beneficial insects in different agro climatic zones of Madhya Pradesh in the year 2017- 2020. Ten different species of beneficial insects were surveyed from the area. Diversity indices were calculated by using Shannon- Weiner index; Margalef’s index and Evenness index. The result shows that the diversity of beneficial insects in forest ecosystem in Madhya Pradesh is rich and diverse.

During the present study 1907 individuals of ten beneficial insects were collected from forest ecosystem of 11 agro climatic zones of Madhya Pradesh. As far as percent composition of each beneficial insect is concerned honeybee, Apis dorsata was the most dominant (35.3%) followed by red ants Oecophylla smaragdina (12.7%), Apanteles machaeralis (10.5%), Canthecona furcellata (8.44%), Antheraea paphia ((6.92), Trichogramma raoi (6.86) , Crocothemis servilia (5.76%), Kerria lacca (5.45%), Coccinella septampunctata (4.40 %) and in Xanthopimpla cera (3.51%) (Fig. 2).The variety and diversity of species in the study sites can be found by calculating Species diversity index, richness and evenness. Analysis of beneficial insect species diversity revealed that the maximum diversity, richness and evenness index was found in the year 2017 (2.08), (1.20) and (0.90) re
