The green peach aphid is important sucking lice on many fruits, vegetables and other crops belonging to over forty different plant families. It has prominent morphological dark green longitudinal stripe on its pale green body. It can damage plants by sucking the sap resulting in water stress wilting and retarding growth of plant leaves especially the growths of seedlings. Their feeding on young leaves causes distortion and transmission of viral diseases. Different management practices have been adopted for their effective and timely management. Proper monitoring was done using different traps including water tray trap, yellow sticky trap and degree days models based on their developmental threshold are used for early diagnosis of their presence. Despite many options available for their control, many producers usually use insecticides for their effective management. Present study focuses to investigate the available insecticides to check their efficacy against this important aphid. Six insecticides i.e., Acetamiprid, Diafenthiuron, Imidacloprid, Thiacloprid, Bifenthrin and Plenum tested against green peach aphids under field conditions on peach trees in Horticultural garden, PMAS-Arid Agriculture University Rawalpindi using Randomized Complete Block Design for statistical analysis. Two frequent applications were used to analyze aphid mortality. Data were taken from the leaves, three replication branches for each insecticide treatment and total of thirty branches after 24hrs and up to ten days.
