New trends in Semiochemicals

The use of pheromones for pest control has become established over recent years, and is now an essential part of the fight against insect pests in agriculture. The specificity, low environmental impact, and proven effectiveness of pheromone-based treatments for major pests are the chief reasons for this recent surge in their development. Moreover, regulatory restrictions on the use of some conventional pesticides have turned pheromones into essential resources to control some major pests.
Pheromone-based methods for pest control may be based on attraction (including trapping or attract-and-kill approaches), but chiefly act through mating disruption.

Pheromone-based methods for pest control may be based on attraction (including trapping or attract-and-kill approaches), but chiefly act through mating disruption. Mating disruption methods currently boast more successful implementations than other pheromonal approaches and are the object of greater research and development efforts, as they are typically more effective and less costly than attraction methods. However, evaluation of many of these methods currently in use has so far been largely empirical: most evaluation exercises merely correlate acceptable damage levels with different forms of application, particularly considering the number, load, and distribution pattern of pheromone dispensers; or else they rely on wind-tunnel observations of behavior. Often, the price of the pheromone is the main component of mating disruption cost; in some cases it is a limiting cost, as certain low-profitability crops have an inherent cost ceiling. The scientific study of certain aspects of mating disruption effects on insects provides for a more rational use of pheromones, leading to more effective treatments and paving the way for such methods to be extended to pests that could not until now be targeted. Use of pheromonal pest control methods, particularly through mating disruption, can only be expanded with greater scientific knowledge of how pheromones affect insects, with reasonable pheromone prices obtained through more efficient synthesis methods, and with a regulatory framework conducive to pheromone registration for practical applications.
