Abstract

The sawfly, Arge xanthogaster (Cameron) (Hymenoptera: Argidae), has recently emerged as a major pest of roses (Rosa spp. L; Rosales: Rosaceae) in Meghalaya and causes around 80% damage to wild and cultivated rose plants. This is a first report of A. xanthogaster as a pest of roses in India. Adults cause ovipositional injuries (split shoots) and larval feeding often results in complete defoliation. The species is multivoltine. Studies on its life history in new habitat are given. Since this species belongs to a species complex of Arge in which species are difficult to distinguish, an attempt was made to develop a DNA barcode based on standard barcoding gene cytochrome oxidase I (COI) of the mitochondrial DNA of this species.

 

El árgido, Arge xanthogaster (Cameron) (Hymenoptera: Argidae), ha surgido recientemente como una de las principales plagas de rosas (Rosa spp L; Rosales: Rosaceae) en Meghalaya y causa alrededor del 80% de daño a las plantas silvestres y cultivadas de rosa. Esto es el primer informe de A. xanthogaster como una plaga de rosas en la India. Los adultos causan lesiones (brotes divididos) al poner los huevos y la alimentación de las larvas a menudo resulta en una defoliación total. La especie es multivoltina. Se presentan estudios sobre su historia de vida en el nuevo hábitat. Puesto que esta especie pertenece a un complejo de especies de Arge en que las especies son difíciles de distinguir, se hizo un intento para desarrollar un código de barras de ADN sobre la base de los códigos de barras estándar gen citocromo oxidasa I (COI) del ADN mitocondrial de esta especie.
