Pheromone Dispenser Each Vial contains 1 mg of the pheromone Delta Trap in Olive Tree Control of Release Rate by Easily Available Means Vials Matrix System (Septa) Sachets in addition to Plastic Pouches The Lure Technology – Early Days

Types of Delivery Systems Employed Laminates Matrix systems Reservoirs Extrusions Attractant incorporated into structure of device Attractant mostly stored in enclosed lumen Laminate More Advanced Lure Technology Membrane systems Release Rate Profile days days Percent remaining Zero Order First Order Interpreting the In as long as mation Pheromone Monitoring

Pheromone Lures as long as over 1000s of species Semiochemicals now come from many sources 1-octen-3-ol An important flavour chemical in mushroom soup – is also an attractant as long as mosquitoes in addition to midges 4aS7S7aR-nepetalactone (cis,trans) Extracted from Nepeta cataria in addition to used in many aspects of aphid pest management para – menthane–3,8–diol Extracted from lemon Eucalyptus citriodora in addition to also synthesised – is a good repellent as long as biting insects Formulations of novel Semiochemicals Nepetalactone in controlled release polymer dispensers R-octenol in addition to ammonia dispenser as long as mosquitoes

Control of Moth Pests with Sex Pheromones Mating Disruption Pheromones are released to interfere with the ability of male insects to locate females of the same species, thereby disrupting mating in addition to controlling the damage to crops inflicted by the hatching larvae. The Principal of Mating Disruption Matrix Systems as long as Controlled Release Frustrate PBW Control of Pink Bollworm Pectinophora gossypiella in cotton 250 devices/ha applied once Lasts 3-4 months Selibate CS Control of Chilo suppressalis in rice 40-100 devices/ha applied once Lasts 3-4 months

Situation Today in addition to in the Future Market as long as pheromone-based control products is about $200 million world-wide currently but growing at over 10% per annum 780,000 ha treated in 2010 with pheromone-based products It has taken nearly 35 years to get to its current size. It is still under 3% of the world-wide Insecticide Market ($9 Billion) This is just the mating disruption market – in the future there will be markets as long as repellents, arrestants, dipersal or alarm pheromones, attractants as long as beneficial insects in addition to many more – All Requiring Controlled Release
