| dc.description | Banana is ravaged by number of insect pests, diseases and nematodes, of them, insect pests play a major role in reducing yield and quality. More than 180 species of insect pests have been recorded on banana world over (Simmonds, 1966). In India, nineteen species infest banana (Padmanaban et al., 2002), which includes major pests such as corm weevil (Cosmopolites sordidus, Germar ), pseudostem borer (Odoiporus longicollis, Olivier), banana aphid (Pentalonia nigronervosa f. typica Coquerel), tingid or lace wing bug (Stephanitis typicus, Distant), fruit rust thrips (Chaetanaphothrips signipennis, Bagnall), castor hairy caterpillar (Pericallia ricini, Fabricius), cut worm (Spodoptera litura Fabricius) etc. In recent years, banana industry is facing problem due to several other emerging pests such as banana skipper (Erionota thrax, Linnaeus), spiralling whitefly (Aleurodicus disperses, Russell) and different species of mealybugs. Among these pests, the pseudostem weevil (banana pseudostem borer) [Odoiporus longicollis (Olivier) (Coleoptera: Curculionidae)] is one of the serious monophagous pest limiting the production and productivity of bananas. In recent years, severe incidence of banana pseudostem weevil has been reported from different parts of India and it is becoming very serious in southern India particularly in Tamil Nadu and Kerala (Justin et al., 2008). It has been estimated that the stem weevil causes 10-90% yield loss depending on the infestation stage and management efficiency (Prasuna et al., 2008). Because of long life span of the adults and endophytic behaviour of the grubs, conventional methods of control, especially chemical control using the insecticides proved to be less effective. | en_US |
| dc.description.abstract | A survey was conducted during 2014-2015, in major banana growing districts of Tamil Nadu, for assessing the distribution, infestation level and the relative importance of banana pseudostem borer Odoiporus longicollis Olivier. The common susceptible cultivar was Nendran with 43.90% infestation in Kanyakumari, followed by Coimbatore and Tiruchirapalli. Matti and Red Matti specifically grown in Kanyakumari were susceptible with 19.62 and 18% infestation, respectively. Rasthali was the least susceptible variety (0.16 %), followed by stSingan (0.18 %). 50. 83 % respondents ranked pseudostem borer as the most important pest with 1 rank. The technological gap index (TGI) was high in use of pseudostem traps (76.23 %), biological control agent (82.79 %) and the use of pseudostem injector (79.51 %), which are the effective management practices for the management of pseudostem borer. A majority of the respondents (54.10 %) belonged to the high technological gap category, whereas, only 7.38 % were in low level of technology gap. Thus, efforts should be taken to create awareness in the banana growers for the use of eco-friendly bio-control methods against pseudostem borer as well as other pests of banana | en_US |
