Besides apple, its primary host, the codling moth Cydia pomonella uses walnut as a secondary host. Abundance of toxic naphthoquinones, among which juglone prevails, does not restrain this economically important pest insect from infesting walnut, but processes underlying the suitability of this host were yet unknown. Larvae feeding on an artificial diet supplemented with juglone at naturally occ...

The oriental fruit moth, Grapholita molesta (Busck) (Lepidoptera: Tortricidae), is an important pest of most stone and pome fruits and causes serious damage to the fruit industry worldwide. This insect pest has been primarily controlled through the application of insecticides; as a result, G. molesta has developed resistance to many different types of insecticides. To identify detoxification ge...

Three neonicotinyl insecticides, acetamiprid, thiacloprid and clothianidin, were evaluated for their impact on four species of lepidopteran pests of apple in Washington, the codling moth, Cydia pomonella (L.), the Pandemis leafroller, Pandemis pyrusana Kearfott, and the obliquebanded leafroller, Choristoneura rosaceana (Harris), and Lacanobia subjuncta (Grote & Robinson). None of the neonicotin...

In this study, Isomate-C Plus pheromone dispensers were used in the application of mating disruption method (ÇE) against codling moth Cydia pomonella (L.) (Lep.: Tortricidae) 2018-2019. The study was carried out on ten decares Braeburn, Red Gala, Fuji, Mondial Chief, Galaxy Golden Smith, and B apple cultivars Onikisubat district Kahramanmaraş province. As control area technique (ÇE), dispensers...

The codling moth, Cydia pomonella L. (Lepidoptera: Tortricidae), a worldwide apple pest, is classified as a freeze-intolerant organism and one of the most cold-tolerant pests. The objectives of this study were to examine the supercooling point of overwintering and non-diapausing larvae of C. pomonella as an index of its cold hardiness, and to assess larval mortality following 24 h exposure to e...

Codling moth, Cydia pomonella (L.), remains a principal insect pest of tree fruit orchards throughout the temperate regions of the world (Barnes 1991; Beers et al. 1993). Its larvae bore deep into the fruits of apple, pear and walnut making them unmarketable. The majority of conventional growers still rely on chemical insecticides to control this insect. However, concerns regarding development ...

Commercial Cydia pomonella granulovirus (CpGV) products have been successfully applied to control codling moth (CM) in organic and integrated fruit production for more than 30 years. Since 2005, resistance against the widely used isolate CpGV-M has been reported from different countries in Europe. The inheritance of this so-called type I resistance is dominant and linked to the Z chromosome. Re...

Two different baculovirus genes are known to be able to block apoptosis triggered upon infection of Spodoptera frugiperda cells with p35 mutants of the insect baculovirus Autographa californica nuclear polyhedrosis virus (AcMNPV):p35 (P35-encoding gene) of AcMNPV (R. J. Clem, M. Fechheimer, and L. K. Miller, Science 254:1388-1390, 1991) and iap (inhibitor of apoptosis gene) of Cydia pomonella g...
