Bionomics of two key pests Barathra brassicae and Tetranychus viennensis in poppy (Papaver somniferum).
Poppy (P. somniferum [Mamestra brassicae]) is one of the most important medicinal plants. It contains opium and its derivatives can be used in the pharmaceutical industry as narcotic analgesics, hypnotics and sedatives. The bionomics of the 2 key pests in poppy, cabbage armyworms (Barathra brassicae) and red spider mites (Tetranychus viennensis [Amphitetranychus viennensis]) were investigated. Larvae of the cabbage armyworm are gregarious, and feed mainly on leaves and seeds of poppy plants. Red spider mites mainly damage perennial poppy plants, especially during the summer and dry seasons.
