Comparative Efficacy of the Different Power Sources in Light Trap during Rabi Season

The present investigation entitled, “Comparative efficacy of different power sources in light trap against major phototactic insect pest of rabi season” was carried out at the BSP (Breeder Seed Production) Farm, Adhartal, JNKVV, Jabalpur (MP) during rabi (mid-November 2022 to mid-April 2023) season 2022-2023.Four light traps design were used in study via. T1 – Solar light trap (with 40 cm funnel diameter, T2 – Solar light trap (50 cm funnel diameter), T3 – Electrical light trap (with 40 cm funnel diameter), T4 – Electrical (with 50 cm funnel diameter). All four light traps were operated every evening and collection was collected every morning for the duration of the investigation for 12 species viz., Helicoverpa armigera, Agrotis ipsilon, Creatonotus gengis, Spodoptera litura, Gryllus bamaculatus, Gryllotalpa orientalis, Nezara viridula, Amata cyssea, Asota ficus Perina nuda, Thysanoplusia orichalcea and Theretra oldenlandiae analysis daily data were combined into weekly totals, this data was subjected to analysis in paired and two sample t-test. In conclusion, electrical light traps were superior in terms of trapping efficacy compared to solar light traps for most of the species collected. The advantage of electrical light traps is in their ability to provide continuous illumination while the power is on, which ensures a higher attraction and capture rate of insects. On the other hand, solar light traps have limitations in providing consistent and sustained light throughout the night, potentially leading to reduced trapping efficiency.
