Research is currently being conducted at the Horticultural Research Farm of The University of Agriculture Peshawar, Pakistan, in the spring of 2021. The experiment was laid down in Randomized Completely Block Design (RCBD) with 3 replications 6 treatments and a control comprising of 1 synthetic pesticide used as a standard against P. demoleus and 5 aqueous botanicals extracts were randomly assigned to different plots. At intervals of 14 days, each treatment was applied to the plot it was assigned to. Results revealed that the lemon butterfly (P. demoleus) population was lowest in the plot treated with bifenthrin (13.00, 7.00 and 6.00 larvae plant^-1), neem fruit extract (14.00, 7.22 and 7.55 larvae plant^-1), ginger rhizome extract (15.00, 8.94 and 8.50 larvae plant^-1), black pepper fruit extract (16.00, 9.83 and 9.11 larvae plant^-1), tobacco leaf extract (16.11, 10.27 and 9.83 larvae plant^-1), garlic bulb extract (17.16, 11.11 and 10.61 larvae plant^-1) after first, second and third spray respectively. The highest P. demoleus population was in the plot control (21.27, 21.33 and 21.38 larvae plant^-1). The damage assessment percentage of treated plots was also correlated with P. demoleus. It was found that damage due to P. demoleus ranged from (50.28% to 73.56%) with maximum damage from 15^th May to 1^st July whereas, the minimum damage was observed from 1^st July to 15^th August but again increased after 15^th August. Biochemical analysis of healthy vs infested plant leaves was also investigated. It was found that leaves with higher Ca⁺² concentration were more prone to/attack by P. demoleus. However, leaves with higher K⁺ concentration was attacked in lower numbers/ of P. demoleus. Based on the current study among all treatments, bifenthrin was found more effective against both the insect pests of citrus and is therefore recommended for managing these pests effectively. However, among plant extracts, Neem fruit extract proved to be effective against P. demoleus and is therefore recommended for environmentally safe management against these pests in nurseries and kitchen gardening.
