Sex pheromones and aggregating pheromones are the most common types used. A pheromone-impregnated lure is encased in a conventional trap such as a bottle trap, delta trap, water-pan trap, or funnel trap. Pheromone traps are used both to count insect populations by sampling, and to trap pests such as clothes moths to destroy them.
A simple light trap A more complex moth trap. Entomologists primarily use light-based moth traps, which exploit the phototactic behavior of moths, attracting them to a light source. Moths navigate by using natural light sources such as the moon and stars, and artificial light sources can confuse and draw them in.
Female M. hutchinsoni employ a specialized hunting tactic where they aggressively mimic the pheromones of moths to attract male moths near their bolas trap. Female moths produce a complex pheromone typically combining two compounds in a ratio specific to the species. This allows male moths to easily distinguish between mates of different species.
In pest control, the use of pheromones in attractant traps to control insects is common practice. This can involve attracting the insects to kill them with an insecticide or physically to trap them or for monitoring. Bark beetles are attracted with aggregation pheromones to trap them. The attractant is usually released when drilling into spruce ...
Pheromone traps work by attracting organisms with a pheromone and then using some means of trapping them. In field studies with P. citri, this pheromone can be applied to a sticky trap to capture males. Male mass trapping aims to trap the males of a species; therefore, fewer females are fertilized, and the number of moths in the generation will ...
Pheromones of certain pest insect species, such as the Japanese beetle, acrobat ant, and the spongy moth, can be used to trap the respective insect for monitoring purposes, to control the population by creating confusion, to disrupt mating, and to prevent further egg laying.
