Online published on 21 July, 2020. Abstract Spiders are preying upon majority of phytophagous insects and remain in the ecosystem for a long time even after harvesting of crops. An experiment was conducted in the Biocontrol laboratory of Jawaharlal Nehru Krishi Vishwavidyalaya, Jabalpur to determine the predatory potential of spider Hyllus semicupreus (Araneae: Salticidae) as test predator on tobacco caterpillar Spodoptera litura (Lepidoptera: Noctuidae). The study revealed that the predatory potential varied from 20 to 100% according to prey density and fall under II type of the functional response, as regards guild functioning.
