Researches Regarding the Use of Mating Disruption Pheromones in Control of Apple Codling Moth - Cydia pomonella L

Abstract

The climatic changes of the latest years led to obvious changes in the biological cycle of the many orchard pests. In the case of the apple codling moth -Cydia pomonella L., one of the most damaging pest of the apple orchards, under our Country conditions it can develops also the third generation, the adults flight extent became wider, the attack of the second generation of larva is more aggressive and under some particular orchard conditions resistance to various groups of insecticides were noticed. The work presents the results obtained during 2013-2014 at Research Institute for Fruit Growing Pitesti Romania, using matting disruption method. ISOMATE C pheromone dispensers (E,E-8,10-dodecadiene-1-ol 52.4%, 1-dodecanol 30.6%,1tetradecanol 7.1%) combined with a reduced number of treatments with insecticides were used to control apple codling moth. The percentage of the attacked fruits in the plot where pheromone dispensers were applied was 0.3-0.4% (in 2013) and 0.08-0.011% (in 2014). The results obtained during the study revealed that matting disruption is an efficient alternative method to control apple codling moth -Cydia pomonella L., which contribute to environment protection and cleaner high quality fruits production.

Efficacité de la confusion sexuelle contre <i>Thaumatotibia</i> (= <i>Cryptophlebia</i>) <i>leucotreta</i> (Lepidoptera: Tortricidae) dans les exploitations cotonnières en Côte d’Ivoire

“…Les . La confusion sexuelle est donc effective car elle a été totalement observée dès la semaine qui a suivi la mise en place des diffuseurs, comme cela a été démontré par Sumedrea et al (2015) sur le carpocapse Cydia pomonella L. et par Boguslawski and Basedow (2001) en Egypte sur le ver rose P. gossypiella. La réduction des captures, dans les pièges à phéromone dès la mise en place des diffuseurs dans les parcelles sous confusion a traduit l'incapacité des papillons mâles à localiser les femelles pour s'accoupler, dénotant ainsi d'un bon contrôle des populations par les pièges (Sumedrea et al, 2015 ;Frérot et al, 2013).…”

“…Le diffuseur ISOMATE FCM 240 a prouvé son efficacité et les avantages dont bénéficieraient les paysans qui l'utiliseraient. La mise en oeuvre d'une telle méthode de lutte pourrait amener à réduire le nombre de traitements insecticides comme l'ont montré Sumedrea et al (2015).…”

Assessment of Granulovirus, Spinosad, and Mating Disruption for Controlling Cydia pomonella L. [Lepidoptera: Tortricidae] in Organic Coastal California Apple Orchards

“…Spinosad has been shown to reduce codling moth populations and fruit damage caused by codling moth larvae in apples (Arthurs, Lacey and Miliczy 2007). Mating disruption in the form of female sex pheromone, Codlemone®, has been shown to reduce codling moth populations, is species specific, and has no effect on beneficial organisms (Sumedrea, et al 2015). Efficacy of these organic materials in controlling codling moth varies from 2 to 90% reduction in fruit damage (Arthurs, Lacey and Miliczy 2007).…”

“…Mate finding can be obstructed by permeating the atmosphere with species-specific synthetically produced codling moth pheromone, Codlemone®, thereby reducing the need for companion insecticide applications (Witzgall, et al 2008). Mating disruption has been widely used among apple and pear growers and has been shown to be successful in decreasing fruit damage (Sumedrea, et al 2015).…”

“…Pheromone disruption techniques only work to prevent mating, having no effect on females that have already successfully mated and are able to fly into treated areas unaffected by the pheromone (Sumedrea, et al 2015). 2009).…”
