8,10-Dodecadien-1-ol as a Pheromone Component: Pre-Exposure Effects on Male Codling Moth Behaviour

The effect of pre-exposure to codling moth sex pheromone on the pheromone-mediated behavior of male moths.

Judd, Gary JR, et al. Entomologia experimentalis et applicata 114.1 (2005): 65-78.

8,10-Dodecadien-1-ol (codlemone) is the major sex pheromone component of the codling moth (Cydia pomonella). Pre-exposure of males to codlemone under controlled conditions induces dose- and time-dependent reductions in subsequent antennal sensitivity, behavioural response, and attraction, with implications for mating-disruption strategies.
Experimental Protocol: Male moths were pre-exposed to codlemone in static air (35 μg/L) or moving air (0.9-18 μg/h) for 2-30 min, then tested in a flight tunnel for upwind flight and source contact. Electroantennograms (EAGs) measured antennal sensitivity. Field exposure used orchards treated with 1000 Isomate-C dispensers /ha.
Performance Evaluation: Pre-exposure to 500 μg for 30 min reduced attraction by 99% and significantly lowered EAG responses. Recovery of full antennal sensitivity required >1 h, but behavioural recovery took >4 h, suggesting habituation. Pre-exposure in moving air (75 min at 18 μg/h) caused 99% disruption. However, 30-h field exposure to orchard air with dispensers (estimated concentration ng/m³) had no measurable effect on subsequent flight-tunnel response, though trap catches in the treated orchard were completely inhibited.
Conclusion: Codlemone pre-exposure induces long-lasting adaptation and habituation only at high concentrations (near-source contact), not at average atmospheric field levels, indicating that close encounters with dispensers may be necessary for these neurological effects to contribute to mating disruption.

8,10-Dodecadien-1-ol (Codlemone) as a Microencapsulated Mating Disruption Agent Augmented by Pear Ester

Microencapsulated codlemone combined with pear ester reduces moth catches and fruit damage.

Kovanci, Orkun B. Journal of Pest Science 88.2 (2015): 311-319.

Codlemone, the major sex pheromone component of codling moth (Cydia pomonella), is formulated as a microencapsulated sprayable pheromone (Ph-MEC) for mating disruption. Co-application with microencapsulated pear ester (DA-MEC) enhances its efficacy by interfering with both male and female orientation and reducing fruit damage.
Experimental Protocol: Field trials in two apple orchards (2009-2010) compared Ph-MEC alone (25 g a.i./ha), DA-MEC alone (5 g a.i./ha), and their combination in high-volume (635 L/ha) or ultra-low-volume (40 L/ha) sprays, applied four times per season. Moth catches were monitored with dual lures (codlemone + pear ester). Fruit damage was assessed mid-season and pre-harvest.
Performance Evaluation: Ph-MEC alone reduced trap catches by 61 % and the combination by 85 % (both spray volumes). Combination treatments achieved 85-93 % reduction in fruit infestation over untreated controls. DA-MEC alone was less effective (43 % trap shutdown). Female catches in DA-Combo traps were low (9-14 % of total moths) across all pheromone-treated blocks. Mating status of captured females did not differ significantly between treatments.
Conclusion: Codlemone microcapsules effectively disrupt mating, and co-application with pear ester significantly improves performance, offering an integrated tool for codling moth management.
