Use of Pheromone Traps in Integrated Pest Management
If pheromone traps are used in the field, the male insect can be caught in the trap by being attracted to the artificial odour of the female insect. The odour of different insects varies greatly in nature. Such artificial temptations are produced in the laboratory at a commercial level.
Pheromone trap functioning methods:
Male insects are drawn to female lure and are therefore captured in the trap. A once-stuck male cannot escape, according to the trap structure. Falling into a pheromone trap prohibits male insects to mate with female insects, thus forbidding the production of eggs.
Role in pest management:
When insects are scarce, it is essential to use cane traps to capture mites. Setting a large amount of pheromone traps can assist capture a huge amount of moths and, in addition, help reduce further reproduction. The cost of pheromone traps is much lower than pesticides. Traps are easy to use throughout the year, only to be replaced with regular lures.
Care to be taken when using Pheromone traps:
• Select the lure according to the type of crop pest
• Use 15 to 20 traps per hectare to capture a large amount of moths
• The trap lures should be changed after 3-5 days
• Traps should usually be put at the height of the plant from 2 to 3 feet above ground level
• The moth caught in the trap should be frequently removed and destroyed
