Attractants drawback insect sex

Sex pheromones are powerful chemical attractants emitted by female insects to attract males for mating. Pheromones of many species have been identified and are synthetically produced for use in insect pest management programs. Some pheromones attract only one type of insect, while others attract several related species. They can be used to monitor the arrival of pest populations, as a mass-trapping control method, and for mating disruption. Note that not all lures contain pheromones. Some include floral or food analogues that attract females as well as males e.

Pheromone-mediated mating disruption MD represents an important tool to manage insect pests in agriculture and forestry. MD relies on the release of synthetic sex pheromones from dispensers in crops, interfering with mate finding and reproduction of a pest through both competitive and non-competitive mechanisms. However, the mode of action of aerosol dispensers is still not well understood and there are concerns of whether they are as effective as passive dispensers. This review focuses on the history of aerosol dispensers, mode of action, and effectiveness on various crops; deployment strategies; and the movement of pheromone once released. Limitations of aerosols and challenges for future research and commercial use are discussed. Currently, the European Commission Directives and Regulations are strongly encouraging a major reduction in pesticide use [ 1 ], with the aim of boosting the production of residue-free foods and reducing the negative impacts of pesticides on human health and the environment [ 2 , 3 ].

Pheromone trap

Insects and sex. Most organisms reproduce sexually, but the evolution of sexual reproduction is not yet well understood. Sexual reproduction leads to new variation and adaptations to the environment, but sex is also costly. Some insects reproduce without sex through parthenogenesis or paedogenesis.

A pheromone trap is a type of insect trap that uses pheromones to lure insects. Sex pheromones and aggregating pheromones are the most common types used. A pheromone-impregnated lure, as the red rubber septa in the picture, 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. Pheromone traps are very sensitive, meaning they attract insects present at very low densities.
