Cold Storage to Control Codling Moth Larvae in Fresh Apples

Abstract

<jats:p>Codling moth [<jats:italic>Cydia pomonella</jats:italic> (Lepidoptera: Tortricidae)], found in exported apples (<jats:italic>Malus sylvestris</jats:italic>), 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.</jats:p>

Meat Traceability: Traditional Market Shoppers’ Preferences and Willingness-to-Pay for Additional Information in Taiwan

“…Therefore, the implementation of a food safety concept is necessary [8][9][10][11] since these concerns can significantly affect consumers' choices [12]. In Taiwan, past scandals, including avian influenza cases (2015) [13], mad cow disease, dioxin defilement, high percentages of pesticides remaining on agriculture products (the 1990s) [14,15], a codling moth larvae outbreak (1990s) [16,17], and the prominence of footand-mouth disease (1997) [18,19], lessen citizens' trust in food safety [20]. Therefore, food-safety-oriented consumers must be guaranteed safety and quality as they become more selective in buying.…”

Fate of Codling Moth (Lepidoptera: Tortricidae) in Harvested Apples Held Under Short Photoperiod

“…The remaining six larvae came from cold storage durations of 8 wk or less. Hansen et al (2007) found that cold storage of infested apples at 1.1ЊC all codling moth larvae destined to diapause were killed within 7 wk, and nondiapausing larvae were controlled within 12 wk. This is most likely the reason why no codling moth larvae have been detected by regulatory ofÞcials upon inspection in Taiwan after 19 December in any year (M. Willett, personal communication).…”
