Distribution of Anomis flava (fabricius) (lepidoptera: noctuidae) larvae on mungbean, urdbean and cowpea

Spatial distribution pattern of larvae of Anomis f1ava (Fabricius) was studied on mungbean [Vigna radiata (L.) Wilczek], urdbean [Vigna mungo (L.) Hepper] and cowpea [Vigna unguiculta (L.) Walp.] during kharif seasons of 1992 and 1993. About 50% time the values of various indices were less or close to random distribution and rest ~f the values revealed aggregated behaviour. However, the values of several indices did not reveal strong aggregation as one could think of in aphids or in similar cases. Distribution pattern on all the three crops was similar and it was not influenced by the stage of the crop and different seasons.
