Evaluation of Sulfoxaflor 50%WG against Tea mosquito bug, Helopeltistheivora Waterhouse (Hemiptera: Miridae). Radhakrishnan B. and…, The principal landmark in the history of tea research in south India, was the establishment of a Tea Experimental Station in Gudalur in 1926. Eggs are bright red, elliptical, laid in clusters; incubation period is 7-10 days; developmental stages include three legged larva, protonymph and deutonymph and each developmental stage is followed by a quiescent stage; life cycle completed in 30-36 days. The spray volume can be adjusted between 175 and 300 litres per hectare. The pink tea mite – together with some other eriophyoid mite species such as the purple mite, Calacarus carinatus (Green) (Keifer, 1952) – is an important pest of tea (C. sinensis) in Asia, causing discoloration of the leaves and debilitation of the plant (resulting in crop Application of endosulfan 35 EC @ 1000 ml/ha or quinalphos 25 EC 750 ml/ha recommended for its control. Management of mite species . The quotations may be sent to the Director, UPASI Tea Research Foundation – Tea Research Institute, Nirar Dam P.O. Factors influencing incidence of red spider mite of tea, Oligonychus coffeae (Nietner) in Assam Adults and immature stages suck the sap from tender shoots. Developmental stages include six legged larva, protonymph and deutonymph. Uprooting of affected bushes, forking and loosening soil and taking 60 X 60 X 60 cm pits 3-4 months prior to planting and keeping them open for aeration are suggested. Similar observations were reported earlier in pink mite infested tea leaves in South India (Loganathan, 1992). North East India, tea plant is colonized by a complex of pest species including the tea mosquito bug, red spider mite, pink mites, thrips, termites, red slug caterpillar, looper, green leaf hopper etc. Application of endosulfan or quinalphos will be effective. Hepialid borer, Sahyadrassus malabaricus (Hepialidae: Lepidoptera): Young caterpillars bore into the stems; excavate long cylindrical tunnels; eating of bark and sapwood resulted in cankers; top end of the tunnel opens into cankers; feeding takes place at night; it can move forward and backward with equal ease; attacked bushes can be easily located by the frassy mat, formed of powdered wood and silk, hanging near the holes; they have grey forewings with faint mottlings; male produce sharp, pungent, mustard like smell by the scent glands; eggs are broadcast by the female in flight; a few succeed in tunneling the tea stems; caterpillars made very long galleries extend up to roots; mature larva is pale yellow, pencil thick and 6-10 cm long; Larval duration is 10 months; pupated in the lower part of the tunnel; pupal period lasts for 3-5 weeks. Epsom salt is pink colored magnesium sulfate. Especially it is the best ingredient you can use for a refreshing bath. (Isoptera): Damage tea bushes in north-east India while Glyptotermes dilatatus, Neotermes greeni and Postelectrotermes militaris attack tea in Sri Lanka. Tea Red spider,Scarlet,Purple,Pink mites 2.25 Kg Cucurbits Powdery mildew 2 gm/Litre of water 7 Ronovit 80 WG AP-388 Bayer CropScience Limited Tea Red spider mites 2.20 Kg Jute Yellow mites 0.12% formulated 8 Cosavet DF AP-397 Alpha Agro Limited Jute Yellow mites 880 gm Addition of non ionic wetting agent (5 ml/10 l of water) will be helpful in achieving better control. Mealy bug, Nipaecoccus viridis (Pseudococcidae: Homoptera: Hemiptera): Feeds on the young shoots and its severe infestation leads to defoliation. The research activities include investigations on physico-chemical properties of soil, soil-plant interactions, response of tea to major, secondary and micronutrients and their interactions. Biological control measures include allowing the build up of natural enemies (phytoseiid mites and coccinellid beetles (lady bird beetles) in tea ecosystem and application of spore suspension of the entomopathogen, Verticillium lecanii @ 1.5 kg/ha in the evening hours when humidity is more. 750 ml/ha recommended for its control pre heating of nursery soil and check the organic manure/compost thoroughly for or..., Albizia and Erythrina you might not feel the bite until after it happens or notice the mite 's cycle!
