Stem borer incidence and distribution varied significantly between the two states. In Maharashtra, the highest incidence was recorded in Amravati district (40%), followed by Yavatmal (39%). In Andhra Pradesh, the highest incidence and damage were recorded from Medak (31%), followed byMahbubnagar (30.3%). The natural enemies recorded in the survey included three larval parasitoids, viz. Cotesia ruficrus (Haliday) and C. flavipes Cameron, and Sturmiopsis inferens Townsend and one pupal parasitoid Xanthopimpla stemmator Thunberg. While species composition did not vary between the two states, species predominance varied considerably, such that Cotesia spp. were predominant in Maharashtra, and S. inferens in Andhra Pradesh. date: 1999 date_type: published publication: International Journal of Pest Management volume: 45 number: 1 publisher: Taylor & Francis pagerange: 3-7 refereed: TRUE issn: 0967-0874 official_url: http://dx.doi.org/10.1080/096708799227978 related_url_url: http://scholar.google.co.in/scholar?as_q=%22Incidence+and+distribution+in+sorghum+of+the+spotted+stem+borer+Chilo+partellus+and+associated+natural+enemies+in+farmers%27+fields+in+Andhra+Pradesh+and+Maharashtra+states%22&num=10&btnG=Search+Scholar&as_epq=& related_url_type: author citation: Duale, A H and Nwanze, K F (1999) Incidence and distribution in sorghum of the spotted stem borer Chilo partellus and associated natural enemies in farmers’ fields in Andhra Pradesh and Maharashtra states.
