Revista Brasileira de Entomologia 55(3): 454–456, setembro, 2011 The Diamondback moth (DBM), Plutella xylostella (Lin-

pest of wild and cultivated Brassicaceae plants (Mussury et al. 2002; Ulmer et al. 2002). It is adapted to different cli-matic conditions (Martínez-Castillo et al. 2002) and causes serious economic losses worldwide (Jankowska & Wiech 2006). DBM presents high genetic variability (Garcia Campos et al. 2006), large number of annual generations, and high fertility (Ulmer et al. 2002), which facilitate the develop-ment of resistance to insecticides. Cross-resistance for organophosphates and pyrethroids has been observed (Yun Cheng 1985). Sarfraz & Keddie (2005) reported the physi-ological capacity of P. xylostella to detoxify glucosinolates, the natural defense system of Brassicaceae. DBM integrated pest management combines adequate pesticide use, biological control, floristic diversity in the field and trapping crops. Biological control can be very effective if control agents are available. There are over 90 parasitoid species recorded attacking the DBM larvae and pupae in in-tegrated pest management programs for commercial cabbag
