Item Biological Control of Pests of Coconut(2000) Pillai, G.B.; Antony, J.; Mohan, K.S.; Mariamma Daniel; Devasahayam, S.; Sathiamma, B.; Dangar, T.K.; Ramachandran, C.P.; Abraham, V.A.; Bhat, S.K.; Sreekumar, K.R.; Sukumaran, A.S.; Chandrika Mohan; Murali Gopal; Sosamma, V.K.; Gulsar Banu, J.Item Biological suppression of Oryctes rhinoceros by re-release of Baculovirus oryctes in an infected contiguous area(2007-02-08) Biju Babjan; Sudha Devi, K.; Dangar, T.K.; Sathiamma, B.Item Effect of baculovirus infection on carbohydrate, protein and amino acid levels, and protease activity in haemolymph of Oryctes rhinoceros grubs(2007-02-08) Biju Babjan; Sudha Devi, K.; Dangar, T.K.; Sathiamma, B.; Pillai, G.B.The effect of baculovirus infection on the levels of sugars, proteins and aminoacids was studied in the haemolymph of third instar grubs of Oryctes rhinoceros. Baculovirus infected grubs maintained almost identical levels of total sugars as the healthy grubs at different stages of analysis. Total protein level was higher in the healthy grubs when compared to that in diseased ones, but reverse trend was observed in protease activity and amino acid levels. The dl4 post-infection was the critical phase at which drastic variations of the macromolecules occurred in the haemolymph.Item Infection of Red Palm Weevil by Microbial Pathogens(2007-02) Dangar, T.K.; Banerjee, A.Item Infection of Red Palm Weevil, Rhynchophorus Ferrugineus, by a Yeast(1997-12) Dangar, T.K.Item Infection of the coconut palm beetle, Xylotrupes gideon (Coleoptera: Scarabaeidae), by a nonoccluded baculovirus(1994) Dangar, T.K.; Solomon, J.J.; Pillai, G.B.Item Integrated Control of Rhinoceros Beetle(2007-02) Pillai, G.B.; Dangar, T.K.; Sathiamma, B.The rhinoceros beetle, Oryctcs rhinoceros L. is one of the key pests of the coconut palm. Adoption of mechanical, cultural, chemical and biological methods in an integrated manner is feasible for the effective management of the pest. Release of the reduvid predator Platymeris laevicollis can also be combined with the above operations, provided the crown treatment with insecticide is eliminated from the schedule. The entomogenous fungus MambMum anisopliae produces epizootics in Oryctes population. Baculovirus of Oryctes is one of the most successful microbial control agents employed for the biosuppression of the pest in several countries. Success achieved from the introduction of baculovirus in Minicoy and Androth in Lakshadweep and the impact of re-release of baculovirus to an already infected contiguous area are also highlighted.Item Mass Production of the Entomopathogen Metarhizium anisopliae in Coconut Water Wasted from Copra Making Industry(2007-02) Dangar, T.K.; Geetha, L.; Jayapal, S.P.; Pillai, G.B.Item Taming insect pests in coconut(1991) Pillai, G.B.; Sathiamma, B.; Dangar, T.K.Biological suppression of two key pests of the coconut palm : the rhinoceros beetle and black-headed caterpillar has been achieved through natural enemies—parasitoids, predators and pathogens. Bacuiovirus of Oryctes introduced into Minicoy and Androth (Lakshadweep) in 1983 and 1988 reduced the population density of rhinoceros beetle and its incidence on coconut palms remarkably. While, a number of spiders are major natural enemies of the black-headed caterpillar.
