Item Attraction of red palm weevil Rhynchophorus ferrugweus oliv. to Ferrugineol based pheromone lures in coconut gardens(1999) Faleiro, J.R.; Mani ChellapanWith the synthesis of ferrugineol based aggregation pheromone during 1993, food bailed pheromone traps have been effectively used to monitor and mass trap red palm weevil. This study, aims at assessing the weevil capturing potential of different ferrugineol based pheromone lures in palm weevil infested coconut gardens. Of the different lures evaluated in this study for attractiveness to red palm weevil, it was seen that improved" ferrolure recorded the best captures. 'Ferrolure+' and ferrolure were equally effective in attracting the pest, while the use of food bait along with the pheromone lure in the trap was essential to obtain higher catches and pheromone trap captures were female dominated.Item Evaluation of pheromone trapping protocols for red palm weevil Rhynchophorus ferrugineus Oliv. in coconut plantations.(2002) Faleiro, J.R.; Satarkar, V.R.; Rangnekar, P.A.Item Occurrence of Heterodera oryzicola on banana in Goa(2007-02) Faleiro, J.R.; Koshy, P.K.; Sosamma, V.K.Item Occurrence of Heterodera oryzicola on banana in Goa(1987) Faleiro, J.R.; Koshy, P.K.; Sosamma, V.K.Item Ovipositional Preference of Red Palm Weevil Rhynochophorus ferruginous Olive, to Coconut Cultivars(2001-10) Faleiro, J.R.; Uangnekar, P.A.Item Present Management Technologies For Red Palm Weevil, Rhynchophorus Ferrugineus Oliver (Coleopteran: Curculionidae) In Palms And Future Thrusts(2002-12) Abraham, V.A.; Faleiro, J.R.; Radhakrishnan Nair, C.P.; Saritha S. NairItem A review of the issues and management of the red palm weevil Rhynchophorus ferrugineus (Coleoptera: Rhynchophoridae) in coconut and date palm during the last one hundred years(2006) Faleiro, J.R.The red palm weevil (RPW) Rhynchophorus ferrugineus (Olivier), a concealed tissue borer, is a lethal pest of palms and is reported to attack 17 palm species worldwide. Although the weevil was first reported on coconut Cocos nucifera from South Asia, during the last two decades it has gained a foothold on date palm Phoenix dactylifera in several Middle Eastern countries from where it has moved to Africa and Europe, mainly due to the movement of infested planting material. In the Mediterranean region, RPW also severely damages Phoenix cal1ariensis. Currently, the pest is reported in c. 15% of the coconut-growing countries and in nearly 50% of the date palm-growing countries. Infested palms, if not detected early and treated, often die. However, palms in the early stages of attack respond to chemical treatment with insecticide. RPW has been managed in several countries employing an integrated pest management (IPM) strategy including the use of food-baited pheromone traps. Early detection of infestation in the field is important for the success of any RPW-IPM programme. Ideally, movement of planting material from infested plantations within the country and also from one country to another needs to be stopped. Wherever this is not possible, it is essential to implement strict pre-and post-entry quarantme regimes, wherein only pest-free and certified planting material can be transported. The existing pheromone-based IPM programme can be strengthened by intensifying the search for effective natural enemies, coupled with the introduction of resistance in palms to RPW. This article reviews the work done during the last 100 years on various aspects of RPW viz. life history, damage and symptoms of attack, seasonal activity, spatial distribution, host range, IPM and its main components, including trapping adult weevils and chemical control, besides biological control, host plant resistance and male sterile technique.Item A review of the issues and management of the red palm weevil Rhynchophorus ferrugineus (Coleoptera: Rhynchophoridae) in coconut and date palm during the last one hundred years(2006) Faleiro, J.R.The red palm weevil (RPW) Rhynchophorus ferrugineus (Olivier), a concealed tissue borer, is a lethal pest of palms and is reported to attack 17 palm species worldwide.

Trapping of adult weevil population with food baited aggregation phero-mone (Ferrugineol) traps is becoming an important eco-friendly tactic of the Integrated Pest Management (IPM) programme to tackle RPW infestation in coconut, oil palm and date gardens throughout the world. Since August 1999 a surveillance programme has been implemented to monitor the activity of RPW using pheromone traps. Observations recorded between August, 1999 and July, 2000 on weevil captures from 40 pheromone traps set throughout Goa, showed that trap captures of RPW were female dominated. For every male weevil captured, 1.94 female weevils were trapped during this period, with maximum female activity being observed during April and May, 2000. Although, the natural population of RPW is known to exist in an equal ratio of 1.32 :'1 in favour of males, attraction of more females to pheromone traps, helps not only in monitoring the weevil activity but also to suppress the build up of the pest in the field. Mass trapping of adult weevils in endemic pockets with food baited pheromone traps is therefore, an important component of IPM strategy currently adopted to combat the menace of RPW in coconut.Item Standardising phoromone trap density for -nass trapping red palm weevil in coconut(2003) Faleiro, J.R.; Satarkar, V.R.Item Status Of Pheromone Trap Captured Female Red Palm Weevils From Date Gardens In Saudi Arabia(2001) Abraham, V.A.; Faleiro, J.R.; Al Shuaibi, M.A.; Saad Al AbdanItem A Strategy To Manage Red Palm Weevil Rhynchophorus Ferrugineus Oliv.
