types of traps

1. WELCOME Snehal Arun Mane

2. Practical Visit to meteorological observatory / automatic weather reporting station. Terrestrial and pond ecosystems of insects. Behavior of insects and orientation. Distribution patterns of insects, sampling techniques for the estimation of insect population and damage.

3. Pest surveillance through light traps, pheromone traps and field incidence. Practicable IPM practices- Mechanical and physical methods, Cultural and biological methods. Chemical control – Insecticides and their formulations. Pesticide appliances, insecticide application techniques C alibration of plant protection appliances, Calculation of doses/concentrations of insecticides.

4. Compatibility of pesticides and Phytotoxicity of insecticides IPM case studies– Cotton, Sugarcane, Mango/ Citrus/ Pomegranate. Identification of common phytophagous mites and their morphological characters Identification of rodents, bird pests, their damage and management . Vermiculture – visit to vermiculture unit, Biopesticides used in IPM with mass multiplication of NPV and Entomopathogenic fungi.

5. Pest surveillance through traps . Types of traps Light trap Bait trap Pheromone trap Sticky trap

6. Light trap A light trap consist of light source above funnel and container below to collect the catch the insect. A light source generally oil lamp or electric bulb fluorescent tube.

7. It is used for sampling agricultural pest particularly moths, hoppers and beetles.

8. Disadvantage S ometimes large number of non target species which may be useful one also get trapped . Which is not only cumbersome but also disturb the ecological balance .

9. Bait trap Bait traps are rely on an insect olfaction or sense of smell for attraction. A common attractant is food.(food containing poison )

10. Sorghum shoot fly - fish meal trap

11. Corn maggot - A mixture of yeast and molasses fruit sucking moth - over ripen banana Disadvantage The utility of such traps is short lived due to infection of the bait by micro -organism . Therefore the bait needs to be changed frequently to keep the trap active.

12. Pheromone trap . Pheromone - A chemical used to communicate between individual of the same spp. Synthetic sex pheromone are placed in traps to attract the target species , there is no sorting or identification problem. No power is required as like light trap so, these can be installed in any field.

13. Pheromone traps used in detecting or sampling of fruit flies . Fruit fly trap

14. Funnel trap Pheromone traps / Funnel trap - used in detecting or sampling of S potted bollworm ( Earias spp ) Cotton bollworm ( Helicovepa armigera . ) Codling moth ( C ydia pomonella ) Pink bollworm ( P ectinophora gossypiella )

15. Disadvantage Such traps are is that almost all traps detect only the adult males . Eg- H elicoverpa armigera traps suspended at 1.8 m from the ground.

16. Sticky traps These traps are installed on a wooden stack or bamboo stick at various height above plant canopy .

17. Yellow sticky trap – Use to trap whiteflies ,shore flies thrips , fungus gnats, winged aphid ,leaf miners, scales. But be aware they may capture parasitic wasp, midge flies and beetles. Use with care Reduce hang duration if needed ,just be consistent.

18. White fly Aphid

19. Blue sticky trap – Use blue sticky traps are for thrips only. Which is useful if you need to monitor for thrips But be aware they may capture parasitoids like Aphidius spp. Hot pink is supposed to be another good color for thrips ,but it not commercially available trap color

20. Thrips
