    3. 3. • Though over a hundred species of insects, a few invertebrates and mammals have been recorded as pests on coffee in India, only a few of them are economically important.• Among coffee pests, insects form the major group. Coffee is a perennial plant and is subjected to attack by passing as well as sedentary insects.• Almost all portions of coffee plants are susceptible to one pest or the other.3/30/2013 AJITHKUMAR
    4. 4. • In India, coffee is cultivated under shade trees, which greatly influences the microclimate in the coffee ecosystem.• Coffee pests could be kept below economic injury level by adopting integrated management strategies such as anticipation and continuous monitoring of pest outbreaks, maintenance of optimum over-head shade for judicious management of ecological factors, handling and pruning of coffee bush, conservation and augmentation of indigenous natural enemies, introduction of exotic natural enemies and timely use of need based biopesticides / insecticides.3/30/2013 AJITHKUMAR

    6. 6. 1. White stem borer, Xylotrechus quadripes Coleoptera: Cerambycidae• It is a most serious insect pest of Arabica coffee in India (Hall et. al. 2006) it was first reported in india in 1883.• This is the one of the major cause for coffee decline in india.3/30/2013 AJITHKUMAR
    7. 7. Symptoms of attack and nature of damage• Larvae enter into the hardwood and make the tunnels may extend even into the roots.• Tunnels - tightly filed with the excreta of the grubs.• Infested plants show visible ridges around the stem.• Yellowing and wilting of leaves.• Young plants (7 to 8 years old) attacked by the borer may die in a year3/30/2013 AJITHKUMAR
    8. 8. Larva feeding on bark Tunnels3/30/2013 AJITHKUMAR
    9. 9. 3/30/2013 AJITHKUMAR
    10. 10. • Adult - slender, long beetle (2.5 cm).• Forewings are black with white bands.• Males are generally smaller than females.• Head Male beetle - possesses distinctly raised black ridges.• Female beetle these ridges are inconspicuous.3/30/2013 AJITHKUMAR
    11. 11. 3/30/2013 AJITHKUMAR
    12. 12. Management• Maintain optimum shade on the estates.• Trace the infested plants - flight periods (i.e, during March and September)• Every year - looking for ridges on the main stem and thick primaries.• Collars prune the infested plants, uproot and burn the affected parts.• Remove the loose scaly bark of the main stem and thick primaries using coir glove or coconut husk – kill the eggs• Scrubbing during flight periods - kills the eggs and grubs present in the bark region.3/30/2013 AJITHKUMAR
    13. 13. • Deep scrubbing should be avoided ( sharp implement may injure the green wood and eventually kill the plant)• Swab the main stem and thick primaries - Lindane 20 EC @ 1300 ml in 200 l of water along with 200 ml of any wetting agent.• Spraying the main stem and thick primaries with neem kernel extract may afford good control of the pest.• Field release of predators Apenesia sps for effective control of white stem borer• Field release of white muscardine fungus Beaveria bassiana (2.5 % field infection reported)3/30/2013 AJITHKUMAR
    14. 14. 3/30/2013 AJITHKUMAR
    15. 15. 2. Coffee berry borer, Hypothenemus hampei Coleoptera:Scolytidae• In India, the pest was first noticed on a few plantations in the Nilgiris during early 1990.Symptoms of attack and nature of damage• Pin hole at the tip of the berries (novel region)• Severe infestation - two or more holes may be seen.• Female beetle bores into the berries through the navel region make tunneling and feed inside content• Powdery substance pushed out through the holes3/30/2013 AJITHKUMAR

    17. 17. Identificatio n• Adult - small black beetle with a sub cylindrical body covered with thick hairs.• Males are smaller.3/30/2013 AJITHKUMAR
    18. 18. 3/30/2013 AJITHKUMAR
    19. 19. Management• Proper adoption of cultural practices and phytosanitary measures important for management of coffee berry borer.• Transportation of infested coffee to uninfected areas is the main reason for spread.• Crop bags should be fumigated before delivery to estates to avoid cross infestation.• Timely harvest3/30/2013 AJITHKUMAR
    20. 20. • Gleaning - spreading gunny bags or polythene sheets on the ground after picking the berries - minimize gleaning.• Maintain optimum shade and good drainage• Dipping infested berries in boiling water for 2-3 minutes kills all the stages inside.• Drying of coffee beans – prevents breeding of beetles in stored coffee based on moisture content level. – Arabica (10% moisture content) - 16kg/lit – Roubsta (11% moisture content) - 18kg/lit• Install attractant trap to collect and kill the beetles3/30/2013 AJITHKUMAR
    21. 21. • Install multiple funnel trap and pitfall trap to collect and kill the adults.• Spray application of endosulfan 35 EC at 340 ml/200 lit of water along with 200ml of wetting agent for quite effective.• Chlorpyriphos is also effective in controlling the beetle.• Field release of Cephalonomia stephendarix and phymastichus coffea (parasites) for effective control these pests.• Applications of white muscardine fungus, Beauveria bassiana effectively reduce the borer attack 3/30/2013 AJITHKUMAR
