Seed orchards function as the primary source of high-quality seeds for reforestation in many European countries, but their seed yields can be severely reduced due to seed- and cone-feeding insects. We evaluated various parameters of pheromone-based mating disruption for control of the moths Cydia strobilella and Dioryctria abietella, which are major pests in European Picea abies seed orchards. We applied different types of pheromone dispensers (rubber septa or wax droplets) at different… 
Development of Monitoring and Mating Disruption against the Chilean Leafroller Proeulia auraria (Lepidoptera: Tortricidae) in Orchards
Mating disruption (MD) field trials showed that application of 250 pheromone point sources using the dispenser wax matrix SPLAT resulted in trap shutdown immediately after application, and mating disruption >99% in all orchards for at least 5 months.
Molecular characterization and its binding properties of general odorant binding protein 2 in Dioryctria abietella
Exploring the functions of DabiGOBP2 can help in better understanding the mechanism of the olfactory system of D. abietella and developing novel strategies to control this pest.
Genetic Improvement of Pinus koraiensis in China: Current Situation and Future Prospects
This review summary summarizes the recent progress in the selective improvement of P. koraiensis varieties, such as elite provenance, family, and clones, using various breeding procedures, and proposes future research directions, which will provide new insight for subsequent genetic breeding research on the species.
Optimal strategy in controlling non-vector pest insect using green insecticide and mating disruption with cost-effectiveness analysis
A generic model to describe plant-insect interaction and focuses on the interaction between non-vector pest insect and plant, finding a set of control strategies that regulate the system optimally.
Optimal Pest Control Strategies with Cost-effectiveness Analysis
A cost-effectiveness analysis suggests that a strategy with two measures of green insecticide and plant removal is the most cost-effective, followed by one which applies all control measures, which projects the decrease of potential loss from 65.36% to 6.12%.


It may be feasible to prevent mating of Dioryctria spp.
Potential for mating disruption to reduce cone damage by the spruce seed moth, Cydia strobilella, in spruce seed orchards
It is suggested that mating disruption has potential for controlling C. strobilella and to protect seed cones in white spruce seed orchards.
Mating Disruption of Paralobesia viteana in Vineyards Using Pheromone Deployed in SPLAT-GBM™ Wax Droplets
It is indicated that wax-deployed pheromone can reduce crop infestation by P. viteana after 2 years of deployment, and that the increasing of phersomone release by using application of greater droplet densities or by using larger droplets will improve the level of disruption achieved.
Mating disruption of Coleophora deauratella (Lepidoptera: Coleophoridae) using laminate flakes in red clover seed production fields.
Pheromone-mediated mating disruption with laminate flakes has the potential to suppress C. deauratella populations and may help to reduce damage even at high pest densities.
Aerial Application of Pheromones for Mating Disruption of an Invasive Moth as a Potential Eradication Tool
Mating disruption enhances Allee effects which contribute to negative growth of small populations and, therefore, it is highly suitable for area-wide control and eradication of biological invaders.
Mating disruption of pea moth (Cydia nigricana) in organic peas (Pisum sativum)
It is concluded that mating activity was only prevented in cage tests, whereas substantial mating occurred during the transit phase outside the pheromone‐treated fields either within non‐crop vegetation and/or at the edges of phero‐treated pea fields orientated upwind, which can be regarded as the major constraint to reliable MD control.
Identification of the Sex Pheromone of the Spruce Seed Moth, Cydia strobilella L.
The spruce seed moth, Cydia strobilella L., is a serious pest on cones of spruce (Picea spp.) in the Holarctic region. Previous studies from different parts of its area of distribution have reported
Efficacy and Mechanisms of Communication Disruption of the Red Clover Casebearer Moth (Coleophora deauratella) with Complete and Partial Pheromone Formulations
It is suggested that both formulations have the potential to disrupt pheromone communication in C. Deauratella, but that the disruption mechanisms of the two formulations likely differ.
Spatial distribution of pheromone in vineyards treated for mating disruption of the grape vine mothLobesia botrana measured with electroantennograms
The spatial distribution of the pheromone of the grape vine moth was measured in vineyards treated for mating disruption by using an electroantennogram technique and the results indicate that inside the borders of treated areas the phersomone was evenly distributed.
Reduction in an almond moth Ephestia cautella (Lepidoptera: Pyralidae) population by means of mating disruption.
It is suggested that this statistical approach may be used more frequently in mating disruption experiments where it is extremely difficult to control external factors and therefore equally difficult to use a comparable control plot to evaluate the treatment.
