Confirmatory tests were performed on a two-component quarantine treatment against the codling moth (Cydia pomonella L.) (Lepidoptera: Tortricidae) for seven apple [Malus sylvestris (L.) var. domestica (Borkh.) Mansf.] cultivars ('Delicious,' `Golden Delicious,' `Braeburn,' `Fuji,' `Gala,' `Jonagold,' and `Granny Smith') intended for export to Japan and Korea. Treatment consists of a 55-day cold storage at 40 °F (2.2 °C) or below, followed by a 2-hour methyl bromide fumigation (0.056 oz/ft3 or 56 g·m-3) at 50 °F (10 °C). No eggs or larvae survived this treatment. Comparison tests were conducted on all cultivars to demonstrate no difference in insect responses between a previously accepted cultivar and proposed cultivars. Concentration-mortality responses were determined for each of the components and no statistical differences were found in the regression slopes of pest mortality with controlling variable (either cold exposure or fumigation) among all cultivars. Descriptive mathematical models, developed for the effects of cold storage on egg mortality and for methyl bromide fumigation on larvae mortality, were sigmoid curve equations.

The two-component quarantine treatment was shown to be effective against at least 7,000 codling moth (Cydia pomonella) fifth instar larvae infesting `Fuji' apples (Malus × domestica) in each required confirmation test involving two sizes of cartons. After cold storage for 55 days at 36 °F (2.2 °C), infested fruit were placed in vented cartons, either 20-lb [7 × 12 × 12.5 inches (17.8 × 30.5 × 31.8 cm)], or 40-lb [12 × 12.5 × 20.5 inches (30.5 × 31.8 × 52.1 cm)], then fumigated with 0.056 oz/ft3 (56 g·m-3) of methyl bromide for 2 hours at 50 °F (10.0 °C). After each treatment, either no survivors were present or no moribund larvae survived beyond the first week of post evaluation of the larvae.

Time Required

Australian pome fruit exports to northern America and Japan are rejected if they contain lightbrown apple moth (Epiphyas postvittana Walker) or codling moth (Cydia pomonella Linnaeus) respectively. A warm controlled atmosphere (CA) disinfestation treatment (72 h at 28˚C at 0, 1 or 2 kPa O2 ), followed by varying lengths of cold storage (5 weeks, 10 weeks or 6 months), is described. Four cultivars were studied: Packham’s Triumph pears (Pyrus communis Linnaeus); Royal Gala; Fuji and Pink Lady apples (Malus domestica Borkh.). Consumer panels found that fruit subjected to the 2 kPa O2 warm CA treatment and cold storage were as acceptable as control fruit. This is an important finding as previously published results for a harsher treatment described treated fruit (especially Pink Lady) as being less acceptable than controls. Some advanced ripening was observed for treated Packham’s Triumph pears. After 5 and 10 weeks cold storage, treated Royal Gala apples were generally firmer than the controls. Insects were also subjected to the 2 kPa O2 warm CA treatment. The most tolerant life stage (MTS) of lightbrown apple moth was the sixth instar with an LT95 of 37 days cold storage (0.5˚C) after the 2 kPa O2 warm CA treatment. Comparison with previous research suggests that the 2 kPa O2 warm CA treatment approximately halves the time required in cold storage for effective control of late instar lightbrown apple moth. A LT95 of 81 days was achieved for fifth instar codling moths (considered to be the MTS) and this may need to be reduced for export to Japan. Preliminary observations suggested that there may not be substantial difference between the resistance of non-diapausing and pre-diapausing codling moth larvae to the warm CA followed by cold treatment.

Third Instar Larvae

AbstractAll codling moth larvae, Laspeyresia pomonella (L.), in 100,000 infested apples were killed by fumigation with 32 g/m3 methyl bromide for 2 h at about 17 °C followed by 31–35 days of storage at −0.5 °C. The apples were harvested into bins, fumigated, and placed in a standard cold storage room of a grower’s packinghouse as would be done under commercial conditions. Standard cold storage killed all first and second, and some third, instar larvae in nonfumigated fruit. Cursory sampling indicated that fumigation alone, without subsequent cold storage, could kill all stages. The fumigation and storage treatment did not injure Red Delicious, Golden Delicious, Spartan, Jonathan, or Newtown apples.

Flight Mills

AbstractFlight capacity of codling moths, Cydia pomonella (Linnaeus) (Lepidoptera: Tortricidae), was measured with computer-linked flight mills following exposure to one of two temperature regimes. Codling moth adults were held for 24 hours before flight under either chilled (2 °C) or unchilled (24 °C) conditions. The chilling treatment emulated conditions that codling moths are exposed to pre-release in the Okanagan Sterile Insect Release (SIR) Programme. Moths were assayed on flight mills for eight hours to obtain a measure of flight capacity based on total flight distance. Energy use was assessed by weight loss during flight and post-flight body lipid content compared with similarly treated moths that did not fly. Flight distance did not vary with pre-flight temperature treatment, however moth pre-flight weight influenced flight capacity; heavier moths flew further. Moths chilled before the bioassay used less energy based on reduced weight loss and higher lipid content post bioassay as compared with unchilled moths. The current cold storage procedure used in the SIR Programme does not negatively influence subsequent flight capacity and reduces energy use during flight. Codling moths can fly on average between 7–10km in an eight-hour flight mill bioassay and lipids, at least in part, are used to fuel flight.

Codling moth (CM Cydia pomonella) is a pest of quarantine concern on apple exports to Asian markets Apples exported to Japan must be fumigated with methyl bromide (MB) and then cold stored Ethyl formate (EF) as an alternative to MB is effective against a range of pests This project investigated the effectiveness of EF to control an internal pest such as CM by determining the responses of key insect stages without fruit and inside apples Trials without fruit in a 2 h fumigation showed that latestage CM eggs and third instar CM larvae were the most tolerant life stages requiring a mean concentration of 134194 EF to achieve 99 mortality but 100 mortality of 4th/5th instar CM larvae Trials with CM in fruit in a 2 h fumigation showed that 113 EF resulted in 534 mortality of 4th/5th CM larvae inside apples Increasing the mean concentration to 24 EF increased the mortality of 4th/5th larvae inside apples to 852

Sweet cherries (Prunus avium `Bing') exposed to 113 or 117 °F (45 or 47 °C) in an atmosphere of 1% oxygen with 15% carbon dioxide (balance nitrogen) were heated to a maximum center temperature of 112 or 115 °F (44 or 46 °C) in 41 or 27 min, respectively. Heated cherries had similar incidence of pitting and decay, and similar preference ratings after 14 days of storage at 34 °F (1 °C) as nonheated or methyl bromide fumigated fruit. Heated cherries and methyl bromide fumigated cherries were less firm after 14 days of cold storage than nonheated, control fruit. The stems of methyl bromide fumigated cherries were less green than heated or nonheated cherries. Cherries exposed to 113 °F had lower titratable acidity than nonheated cherries, fumigated cherries, or cherries exposed to 117 °F. Cherry quality after 14 days of cold storage was not affected by hydrocooling before heating (5 min in water at 34 °F) or by method of cooling after heating (hydrocooling, forced air cooling, or static air cooling). Cherries stored for 14 days at 34 °F in 6% oxygen with 17% carbon dioxide (balance nitrogen) had similar market quality as cherries stored in air at 34 °F. Results suggest that `Bing' sweet cherry can tolerate heating in an atmosphere of low oxygen containing elevated carbon dioxide at doses that may provide quarantine security against codling moth (Cydia pomonella) and western cherry fruit fly (Rhagoletis cingulata).

Malus Sylvestris

Codling moth [Cydia pomonella (Lepidoptera: Tortricidae)], found in exported apples (Malus sylvestris), can disrupt international markets. Cold storage at 1.1 °C was examined for possible control of three physiological larval states in ‘Fuji’ apples: diapausing (overwintering), diapause-destined, and nondiapausing. All nondiapausing larvae were dead within 12 weeks, diapaused-destined larvae were controlled by the seventh week, yet more than half of the original populations of diapausing larvae were still alive after 11 weeks. Because the diapaused-destined larvae were younger than the nondiapausing larvae, they may have been more susceptible to cold. Because larvae normally diapause outside the fruit, cold storage would not be applicable for controlling larvae in this state.
