The experiment was conducted behind the biotechnology center, JNKVV campus, Jabalpur (MP) during the period between third week of October 2019 to third week of March 2020. Comparative studies of trap catches revealed that UV 15 watt (model SMV-4) has given better response than UV LED 7 watt solar trap (model Rakshak) in following species – Gryllus bimaculatus and unidentified Lepidoptera moths, But, there is no significant difference between the catches of UV 15 W and 7W UV LED light sources. UV15 w has given better response than UV LED 7 watt in case of Helicoverpa armigera, Gryllotalpa orientalis, Plusia orichalcea, Agrotis ipsilon, Creatonotos gangis with significant difference between the catches of SMV-4 UV 15 watt and SOLAR UV LED 7watt. Taking into consideration the total wattage of consumption i.e. UV 15watt (electric powered) v/s UV-LED 07 watt (solar powered) the UV 07 watt seems to a much cheaper & economic light source than 15 watt. Therefore, solar light source (07 watt UV) seems to be very good alternative source to 15watt for operation of light trap as pest control device. But cost wise compared the both models the solar powered light trap is much costlier.
