Item Attempts on introduction and colonization of the exotic reduviid predator, Platymeris laevicollis distant for the biological suppression of the coconut rhinoceros beetle Oryctes rhinoceros L.(2007-02-08) Antony, J.; Mariamma Daniel; Chandy Kurian; Pillai, G.B.Vander Plank (1958) detected along the east coast of Africa Platymeris laevicollis Dist., a predaceous bug preying on natural populations of Oryctes monoceros Oliv , and O. boas F., which are pests on coconut palm in those regions. However, no such predator attacking and killing adults of O. rhinoceros L. has been recorded from India so far. Hence its predatory habits and alienity have been taken advantage of in a trial on its introduction and colonization against O. rhinoceros in India. Viable culture of the predator was obtained from different sources including its native home viz. Zanzibar. In an attempt to colonize, the predator under different agro-ecological conditions, laboratory bred bugs were released in large numbers on the crowns of palms at Pandalam (Kerala), Androth (Lakshadweep) and Vittal (Karnataka). At Pandalam where field release of the bugs was done from 1968-74, the live population of the beetles in the crownsof one hundred palms under release was observed to be comparatively less than that of the dead beetles collected from the palms on which the predators were released. Consequent on the decrease in population of the beetle and the corresponding dip in incidence of the pest on the crowns of palms the intensity of infestation on leaves and unopened inflorescence had also come down. In Androth Island these bugs were released on 200 palms which were very heavily infested by the beetle with a high population density (243 beetles on 155 palms) On the fifth day after the release of the predator 213 beetles were found fed on and killed by the bug whereas 45 beetles including the newcomers were alive. Indications of establishment of the bug were also noticed at Pandalam, and at Vittal, where the bugs are being released regularly from 1971 onwards. At Vittal the incidence of the beetle in the crown of palms and the consequent reduction of damage on the spindle and spa the continued to be comparatively less than the pre-release incidence. Release of the predator at Vittal Centre is being continued.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 Biology and predatory habits of the lady bird beetle Stethorus keralicus Kapur (Coleoptera: Coccinellidae), predatory on the palm mite(2007-02-08) Mariamma DanielBiology and predatory habits of the lady bird beetle Stethorus keralicus Kapur were studied. The beetle required 12-14 days to complete the life cycle from egg to adult. Eggs hatch out in 3 . 0-4- 0 days. The larvae moult three times in 5- 0-6- 0 days. The pupal stage is completed in 3 . 5-4-0 days. The adults and larvae feed on all stages of the host mite. An adult consumes 2-41-6-46 mites per hour during a period of 24 hours.Item Control of acarine pests(2015) Mariamma DanielItem The eupelmid egg parasitoid of the pentatomid bug, Halyomorpha marmorea F. in Dakshina Kannada district of Karnataka(2003) Mariamma Daniel; Narendran, T.C.; Keshava Bhat, S.Item Evaluation of plant material, plant products, and oil cakes against arecanut white grub Leucopholis burmeisteri Brenske (Coleoptera : Scarabaeidae : Melolonthinae)(2007-02) Padmanaban, B.; Mariamma Daniel; Srimannarayana, G.Item Integrated management of root grubs in arecanut(2012-06) Alagar, M.; Jaganathan, D.; Mariamma Daniel; Keshava Bhat, S.Item Integrated Pest Management in Palms(1997-01) Nair, C.P.R.; Mariamma Daniel; Ponnamma, K.N.Item Integrated Pest Management in Palms(1997) Nair, C.P.R; Mariamma Daniel; Ponnamma, K.N.Item Investigaion on tendernut drop in arecanut(Central Plantaion Crops Research Institute, Regional Station Vittal, 1999) Chandra Mohanan, R.; Vidyasagar, P.S.P.V.; Mariamma DanielItem A non-destructive method to estimate surface area of areca fruit for entomological studies(1997-06) Padmanaban, B.; Mariamma Daniel; Jose, C.T.Item Observations on phytoseiulus persimilis Athias-Henriot (Acaridae, Phytoseiidae) for control of the phytophagous mites of areca palm(1976) Mariamma Daniel; Seshadri, S.N.Item Pests(1982-12) Radhakrishnan Nair, C.P.; Mariamma DanielItem Pests of Arecanut(2007-02) Mariamma Daniel; Prem Kumar, T.Damage to the arecanut palm due to pests results from feeding on seedlings, roots, stem, foliage, and inflorescence.
