Some ecological issues and their impact on termites (Insecta: Isoptera) occurance in Haryana state (India)

Ecologically, Haryana state has been divided into three zones, viz. arid, semiarid and wet zone on the basis of specially rainfall. The principal ecological factors which influence the abundance, distribution and dispersal of termites are rainfall, atmospheric temperature, humidity, vegetation and soil types. The termite fauna of Haryana comprises of 42 species distributed under 17 genera and four families recorded from 279 localities during the three years (2007-2010) survey. Out of which family Rhinotermitidae and Termitidae are versatile in nature. The family Termitidae is found abundantly in two zones viz. semiarid and wet zone. The family Termitidae consist nine genera (75.00%) and 30 species (88.23%) in semiarid zone in contrast to eight genera (88.88%) and 21 species (95.45%) in wet zone. As the climatic conditions of arid zone is not favourable to the family Termitidae an insignificant amount of 3 genera (42.85%) and four species (50.00%) were reported. The family Kalotermitidae represented only in semiarid zone and having only one genus (8.33%) and one species (2.94%) composition. The niche space for the family Hodotermitidae was confound to arid zone and consist of one genus (14.28%) and one species (12.50%). As the family Rhinotermitidae is versatile in nature, recorded from all the three zones (viz. arid, semiarid and wet zones) the genera and species composition of family Rhinotermitidae is three genera (42.85%) and three species (37.50%), two genera (16.66%) and three (8.82%) species and one genus (11.11%) and one species (4.76%) recorded from arid, semiarid and wet zones respectively.
