Abstract:

In this study the species diversity of rice leaf folder and their natural enemies were studied in three different blocks of Odisha and three Research stations of Odisha University Agriculture & Technology, Bhubaneswar(under North Eastern Coastal plains) during the year 2015 and 2016 at different growth stages of paddy crop on the basis of morphological characteristics, wing marking, coloration, characters of pronotum, subdorsal spots on prothorax and size of the larvae as described by Barrion and Litsinger (1991) etc. The study revealed that three rice leaffolder species were noticed i.e. Cnaphalocrocis medinalis (Guenée), Marasmia exigua (Bradley) and Brachimea arotraea (Meyrick) with the predominance of C. medinalis. Among the Leaffolder species, the highest population of Cnaphalocrocis medinalis (Guenée) (83.34%), was recorded in each location followed by M. exigua (12.22%) and B. arotraea (4.43%) was very meager and all the three species were prevalent in all seasons. The common natural enemy fauna of rice leaf folder C. medinalis comprised of 10 species predatory arthropods. Out of which the predatory beetles belonging to the family Carabidae, Cocconellidae were dominant and among different parasitoids on rice leaf folder, the main spp. observed were, Macrocentrus philippinensis, Cotesia angustibasis and Goniozus spp, from larvae. The extent of parasitization was more in kharif season than in rabi. The mean parasitization during kharif 2015&16, rabi 2015&16 was in the order of 21.8 and 17.02 per cent respectively.
