The introduction of new improved technologies and products is a difficult challenge, especially within a novel IPM domain such as mating disruption in which ‘standard’ and ‘time-tested’ products such as Shin Etsu ‘ropes’ have already taken hold and established themselves as the products of choice. Widely spaced, high-emission-rate pheromone dispensers are one such novel product for mating disruption. These have been in commercial use for many years in both field and fruit-tree crops. The Metered Semiochemical Timed Release System (“MSTRS”) started out in 1993 as a timed, metered aerosol device, but gradually evolved away from the clock-timer ‘active’ release of pheromone to now become an entirely ‘passive’ release system while still retaining its high-emission-rate low-point-source-density attributes. Many factors have influenced the evolution of this system, and our experience with it both on the research front as well as in commercial aspects, has given us new insights into how mating disruption might fit into IPM practices in the future. The biological effects resulting from mating disruption continue to be elucidated and understood, but our first-hand experience with the commercial side of an emerging technology such as this has revealed many challenges that we as research entomologists and biologists have not considered.
