Pheromones are sex attractants. Adult female insect which are ready for mating emit species specific chemical odour to attract males. These specific chemical called Pheromones are synthesized and used for insect pest management in crops. The Funnel Trap consists of a funnel section and a polythene bag. A central pheromone dispenser holder is located on top of the funnel under an umbrella type cover. The traps are used in combination with pheromone dispensers. Funnel traps are useful tools for monitoring moths. They give information on the population density of the pest and help the grower to determine the optimal control strategy. These traps are designed for multi-season use and are resistant to severe weather conditions. They are very easy to assemble and clean.

Helicoverpa armigera (Cotton bollworm), Spodoptera litura (Cut worm), Pectinophora gossypiella (Pink bollworm), Earias vittella (Spotted Bollworm), Scirpophaga incertulas (Yellow Stem Borer), Plutella xylostella (Diamond back moth).
The males, attracted by the female pheromone lure, enter the trap and get hit by the sides of the walls at the base of canopy and fall into the polythene bag and get killed. Traps should normally be attached to stakes at crop height and placed within the crop with at least 50m between each trap. To avoid affecting the efficiency of the trapping system it is strongly recommended that traps be used only for the one species. Never use the dispensers for other insect species in these traps.
