Abstract

Studies on ROSE sawfly (Arge rosae; Hym. Argidae) in 1999 revealed that there was another sawfly belonging to Tenthredinidae family whose larvae also feed upon ROSE leaves. Several specimens of adult sawfly were collected from ROSE by ordinary insect net and identified as ALLANTUS VIENNENSIS (Schr.) (Hym.; Tenthredinidae)and named as minor leaf eating sawfly. Male and female are generally dark in color with yellowish bands on legs and abdomen. Eggs are elliptical, white in color and are laid individually beneath the bark of the young shoots and also soft spins. Newly hatched larvae are yellowish white but become gradually green. The young larvae feed gregariously on the parenchyma of youngest leaves and as larvae grow, they eventually eat the entire leaf except main rib. Feeding also occurs on flower petals causing the color of larvae change into pinkish. Final instar larvae bore into ROSE shoots or enter stem crevices for pupation. There are three generations in a year and over wintering occurs as prepupa in ROSE shoots or broken branches. For determination of SPATIAL DISTRIBUTION PATTERN of this pest Taylor's power law model was used. The results indicated that the distribution of different larval stages populations of this wasp was clumped (b=2.395±0.14).
