Study on various synthetic pesticides and bio-pesticides for managing Helicoverpa armigera (Hubbner): Comprehensive Review

Abstract— Helicoverpa armigera Hubbner has been recognized as one of the most significant agricultural pest and causes damage to tomato fruit crops. Globally, India ranks second in tomato production. 8,14,000 hectares of agricultural land utilized for tomato cultivation, with a net productivity of 20.40 million tonnes in 2022-23. Both chemical and biological methods are employed for crop protection. This research examines various pesticides and bio-pesticides, determining their effectiveness based on LC50 values. The study identifies commonly used synthetic and bio-pesticides in farming, including Coragen (Chlorantraniliprole 18.5%), Acrobat (Dimethomorph 50% WP), Indofin M-45 (Mancozeb 75% W/W) and Tandav (Alkaloid: 10%, Benzanine: 12%). The research reveals that Chlorantraniliprole, Spinosad, Indoxacarb, and Emamectin benzoate show notable results in controlling pest infestations. The combination of Thiamethaxim and Chlorantraniliprole demonstrates the highest efficacy in managing pest populations. Bio-pesticides derived from Jatropha, Beauveria bassiana, and Neem seed extract exhibit a high larval mortality rate of 86%. Beauveria bassiana, Bacillus spp., Serratia spp., and Pseudomonas spp. are also effective bio-pesticides. Trichogramma spp. is found to be the parasitoid of Helicoverpa armigera, destroying pest eggs before they hatch and their predator species of pestinclude Chrysopids and ant species such as Pheidole spp. and Iridomyrmex spp. are effective as biological control of tomato fruit borer.
