- 1. TRAPS IN CROPPESTS MANAGEMENT Presented By- Pooja Singh
- 2. TRAP A device thatimpedes or stops the process of an organism • Population fluctuation & their peak period of emergence • Mass trapping & killing
- 3. TYPES OF TRAPS •Physical (light and sticky traps) • Chemical (pheromone & bait traps) • Mechanical (suction, pit fall and emergence traps)
- 4. LIGHT TRAP • Bonfires are base for development of light traps • Followed by lanterns and kerosene lamps • Light traps were designed
- 5. SOURCES OF LIGHT •Use of various lamps • Quality (wave length) & quantiity (power) • Three major categories 1. Incandescent lamps 2. Mercury vapour lamps 3. Black light
- 6. TYPES OF LIGHTTRAP 1. Simple incandescent light trap 2. A low intensity incandescent light trap 3. Robinson trap 4. Rothamsted light trap 5. Black light trap 6. Electric grid type 7. Light trap with automatic separation of insects
- 7. USES OF LIGHTTRAP • Seasonal incidence for forecasting • Flight pattern and abundance in a locality • To decide spray or not to spray • Migration details can be worked out
- 8. • Attracts nocturnalinsects only • Fixed 2 – 3 feet height above the vegetation @ 5 / ha. • Collection is less in full moon day X new moon day LIMITATIONS
- 9. TARGET PESTS • Leafhopers • Plant hoppers • Bugs • Chaffers • Leaf folder • Stem Borer • Boll worms etc.,
- 10. OPERATION • Attracts beneficialand non target organisms also • Operate only during peak period of incidence For example Rice – 8pm to 12midnight Sorghum – 8 – 11pm
- 11. STICKY TRAP • Toattract aerial and small sized insects • Sticky material – castor oil / vaseline / grease • Stickiness + colour attract more insects White – Pigeon pea fly and weevils Yellow – cotton white fly and aphids Red – Apple maggots • Stickiness + Pheromone is also better
- 12. YELLOW STICKY TRAP •Set in field at different locations 30cm above the ground level • Sticky materials to be replaced once in two days • Erect against wind direction @ 5 / acre Target pests: White flies, hoppers, aphids and lepidopteran insects
- 13. PHEROMONE TRAP • Pheromone– synthetic substance • Available as lures in rubber septa • Deployed at 1m above crop canopy @ 2 -3 / acre • Distance between two traps should be 40m
- 14. (i) UNI TRAP •To capture large number of insects • Durable and cost effective • Recommended for cut worms and army worms TYPES OF PHEROMONE TRAPS
- 15. (ii) FUNNEL TYPE Targetpests: Tobacco cater pillar and boll worms etc.,
- 16. (iii) DELTA TYPE (IV)BUCKET TYPE
- 17. PURPOSE 1. Monitoring 2. Masstrapping 3. Mating disruption
- 18. AVAILABLE LURES • Spodolure • Heli lure • Pectino lure • Ervit ure • Ferro lure • Rhino lure
- 19. POISON BAIT TRAPS BAIT:Food materials mixed with poison or insecticides to trap insects • Used mainly where dusting and spraying not possible
- 20. Perforated plastic containerwith cotton soaked DDVP • To trap sorghum shoot flies FISH MEAL TRAP
- 21. CHEMICAL WITH POISON Ex:Methyl Euginol : DDVP (1:1) Target pest: Fruit flies
- 22. OTHER BAITS • Molasses/ toddy + 0.1 % Nuvan • To trap coconut rhinoceros beetle and fruit sucking moths
- 23. TRAPS FOR RODENTS (I)SINGLE DOSE POISON Zink phosphide (2g) + ground nut oil (3g) + pop corn or rice (95g) (II) MULTI DOSE a) Dry bait: Flour(450g) + edible oil (10g) + jaggery (15g) + anticoagulant (25g) b) Liquid bait: Anticoagulant : water (1:19)
- 24. LIMITATIONS • Pre baitfor 2 – 3 days • Place bait where rats are frequently more • Replace the bait frequently • Discontinue the baiting as soon as rats controlled • In field, keep 30cm from bunds and 5mts. between two stations
- 25. BACK BREAK TRAP •Used in godown / house / field • Easy to handle and carry
- 26. GLUE TRAP • Glueapplied on a card board, wood / plastic • Placed in boxes with openings • Not suitable all the time
- 27. CAGE / LIVETRAP • Box like trap to catch live rats • Easy to handle
- 28. ELECTROCUTION TRAPS • Ratselectrocuted when it enters the trap • One rat trapped at a time
- 29. TRIBAL RAT TRAP •Flat stone and 3 pieces of elongated sticks • Made with in 5 – 10 minutes • Local name is RALANGAL • Used by Malayali tribes of Kalrayan and Kolli hills of TN
- 30. REMODELLED TRIBAL RATTRAP • Flat concrete stone of 30×25cm • An “Y” like wooden stick made with neem wood with 2 arms each 7.5cm and 16cm central length
- 31. BAIT STATIONS • Tincontainers with punctures- Fish meal trap • Mud pot – Molasses • Box type (rectangular box) – Rats • Bamboo type (one side closed with tin sheets) - Rats
- 32. TRAPS FOR STOREGRAIN PESTS (I)TNAU probe trap There are 3 major parts 1. A main tube 2. Insect trapping tube 3. Detachable cone • 2mm perforations • Behaviour exploited- Air loving • Good mass trapping tool @ 2 - 3 nos. / 25kg bin • Removes more than 80 % of insects • R. dominica, S. oryzae and T. castaneum
- 33. PIT FALL TRAP •To capture insects on grain surface • Mass trapping and monitoring tool • There are 2 important parts 1. Perforated lid 2. Cone shaped bottom • Coating with sticky material on the inner side TNAU model: • Simple and made with plastic • Easy to handle
- 34. TNAU TWO INONE TRAP • Components 1. Perforated tube 2. Pit fall mechanism 3. Collection tube • Combination of pit fall & probe trap • Suited for pulse beetle
- 35. UV LIGHT TRAPFOR GRAIN PESTS • Light is fitted at centre of funnel (250nm) • Plastic container used as collection jar • Place at 1.5 – 5.0m above ground level • Erect it in corners • Used to trap Lesser grain borer Red flour beetle Saw toothed beetle and Psocids • 2 nos. per 60 ×20m(L×B) godown
- 36. OTHERS Malaise trap •Used tocollect flying insects (Dipterans and Hymenopterans) • Lepidopterans can also be collected • Made of nylon net
- 37. PIT FALL TRAP •To trap insects on soil surface Ex. Ground beetles and spiders • Made with glass jar contains kerosene and a funnel
- 38. CONCLUSION • Traps areuseful devices to collect various insect pests easily • Used mainly for mass trapping, monitoring of pests in a locality • Plays a major role in IPM • Helps to conserve the eco-system
