The potential for spread of codling moth (Lepidoptera: Tortricidae) via commercial sweet cherry fruit: a critical review and risk assessment
نویسندگان
چکیده
The identity, geographical distribution, and host range of codling moth is reviewed, and the evidence for sweet cherry being a host is critically analysed. A model is described which assesses the risk of codling moth being spread through international trade in sweet cherries, as exempli"ed by exports from, respectively, New Zealand and USA to Japan in winter and summer. The model is based on the recorded incidence of codling moth in cherries and its estimated probability of survival during storage, transport to, and arrival in Japan, using data from speci"c studies and from wider knowledge of the phenology, life history, and biology of the species. There is unambiguous experimental evidence, supported by "eld observations, that sweet cherry is not a host of codling moth. It is concluded that the risk of codling moth establishing in an overseas country such as Japan through the cherry trade is extremely low and that speci"c quarantine measures to prevent the introduction of this insect by this route are not technically justi"ed. 2001 Elsevier Science Ltd.

Sweet cherries, Prunus avium L., from the United States must be fumigated to control codling moth, Cydia pomonella (L.) (Lepidoptera: Tortricidae), before exporting them to Japan. However, the status of sweet cherry as a true host for codling moth has been debated because of the limited survival of the pest. Previously, laboratory methods have been developed to rear the codling moth on sweet ch...

Codling moth (Cydia pomonella L.) is an internal feeding pest of apples and can cause substantial economic losses to fruit growers due to larval feeding which in turn degrades fruit quality and can result in complete crop loss if left uncontrolled. Although this pest originally developed in central Asia, it was not known to occur in China until 1953. For the first three decades the spread of co...

'Bing' cherries, Prunus avium L., were obtained from an organic orchard and a conventional commercial orchard. The two groups were examined separately in replicated tests infested with each fruit initially infested with a first-instar codling moth, Cydia pomonella (L.). To simulate commercial postharvest holding conditions, the treatments were 0 (control), 1, 2, 4, 7, 10, and 14 d cold storage ...

Quarantine regulations require domestic sweet cherries (Prunus avium) exported to Japan to be treated to control codling moth [Cydia pomonella (Lepidoptera: Tortricidae)]. The current procedure, methyl bromide fumigation, may be discontinued because of health, safety, and environmental concerns. To examine a potential alternative method, ‘Bing’ sweet cherries were each infested with a codling m...
