To evaluate the predatory efficacy of Menochilus sexmaculatus Fab. on rose aphid (Macrosiphum rosae) a laboratory experiment was escort during 2012 at 27 2 0C and 62 5% relative humidity (RH) at Entomological Research Institute, Ayub Agriculture Research Institute, Faisalabad. Predation efficiency of the 1st , 2nd , 3rd and 4th instars larvae of M. sexmaculatus were 8.40 ± 0.50, 13.60 ± 0.81, 28.60 ± 1.50 and 57.40 ± 4.67 aphids, respectively while the predation efficiency of male and female adults were 802. 40 ± 2.56 and 916.60 ± 1.69 aphids respectively. The data of the aphid predation beetles unveil that the larvae of the 4th instars showed the highest predation performance and the 1st larval instars confess the lowest one. The female beetles were more cogent in aphid predation as compared to the male beetles.
