Investigation of the species Diversity of the Family Dolichopodidae (Dip. Empidoidea) In different parts of Tehran and Alborz provinces

Preserving and increasing the insect biodiversity is considered as one of the most important components in pest control without the use of chemical pesticides and plays an important role in reducing environmental pollution and achieving sustainable development. Dolichopodidae, the long-legged flies, with more than 7500 described species in about 276 genera is the most important and biggest family of the superfamily Empidoidea. Adults and larvae of the most species are predators of other insects. In the present study, in order to investigate the fauna of the family Dolichopodidae, sampling was performed using entomological nets and Malaysian traps in 2017-2018 in Tehran and Alborz provinces. Species diversity studies showed that the diversity of this family in the areas with high humidity and mixed and abundant vegetation is more than other areas.
