The pseudostemweevil (Odoiporus longicollis) is one of the most dangerous pests inbanana crop. On farm and laboratory experiments were carried out at the KrishiVigyan Kendra, Pechiparai, Kanyakumari District, Tamil Nadu, India during theperiod 2010-2011 to assess the bio-efficacy of Beauveria bassiana,Azadirachtin 10000 ppm and monocrotophos (spray and injection) insecticideagainst pseudostem weevil, Odoiporuslongicollis Oliver (Coleoptera :Curculionidae) in Red banana. Injection of monocrotophos @ 4ml/plant registeredthe highest per cent reduction (76.07%) followed by the injection ofAzadirachtin 2ml/plant (70.0%), application of B. bassiana @ 25g on thepseudostem trap (56.75%) and monocrotophos spray (38.39%). However, applicationof monocrotophos (4ml/plant) and Azadirachtin (2ml/plant) by stem injectionproved to be more effective than by spraying of monocrotophos. Stem injectionof monocrotophos, Azadirachtin and the application of B. bassiana recordedthe highest per cent mortality of 96.15, 84.74 and 75.36%, respectively, after96 hrs of application. All the treatments were found to increase the fruityield with better cost benefit ratio.
