Farmer’s Field was less disturbed eco-system where farmer followed traditional agriculture practices for growing crops. Research Field ecologically was highly disturbed area where scientists were fallowed intensive agricultural practices for growing crops. Light trap was used for study of biodiversity of Hemipteran phototactic insect fauna. Total 37 species of order Hemiptera belongs to 12 families were collected from rice ecosystem. Family Pentatomidae was the dominating family among the all 12 families. 5 species were collected more in number at Farmer’s Field in comparison to Research Field. 37 species were collected at Farmer’s Field, while 32 species were at Research Field. Keywords: Light trap, hemiptera, rice, diversity, taxonomy, eco-system Introduction Rice is a very important crop in India it has occupied 37.38 million ha area under cultivation and production was 104.8 [1] . while in Madhya Pradesh area under rice cultivation was 2.02 million ha and production was 5.32 MT [2] . Rice ecosystem provides favorable conditions for various kinds of invertebrates that inhabit soil, water and vegetation. Over 800 species of insects in rice ecosystems have been reported worldwide. Out of these, 100 species attack rice, while rest are considered as friendly insects [3] . Almost 20 insects are considered as rice pests of economic importance that include stem borers, gall midge, defoliators and vectors like leafhoppers and plant hoppers [4] . According to biodiversity productivity hypothesis [5] , biodiversity plays a significant role in maintaining a sustainable agronomic system. Order Hemiptera is also an integral part of insect bio-diversity in rice eco-system. The order Hemiptera is the largest of the non-endopterygote orders constituting 90000 species in about 140 families. Hemipteran insects are widely distributed found in all major habitats. They play an important role in maintaining the eco-system. Practices like over use of pesticides, monoculture, grazing, poor farming techniques etc. are posing threats to insect biodiversity associated with rice farming system [6] . Agricultural activities create fragmented landscapes, which cause small isolated patches of species to go extinct [7] . These oversimplified environments lead to intensified pest outbreaks, as well as a reduction in critical components of an ecosystem, such as pollinators [8] . In order to gain productive results, it is necessary to conserve diversity in agricultural systems. Light trap is a well-known tool for the study of biodiversity of phototactic insects. Light- trapping has become a general term which refers to all methods of attracting nocturnal insects with lamps or artificial light sources. Phototropic behavior and phototactic response of insects are being largely used to monitor pest activity for their effective suppression [9] . Light trap still occupied an important place in entomological studies world wide for survey, detection and management of insect pest population in various Agro-Horticulture crops [10] . Keeping the importance of biodiversity in mind for maintaining a sustainable agronomic system, this study proposed the insect diversity in rice ecosystem by using the light trap. Materials and Methods The present two year (2015 and 2016) explorative field research on Hemipteran phototactic insects rice ecosystems was carried out at two distinct locations separated from each other by
