The objective of this research was to determine whether immediate cooling of mangoes (Mangifera indica L.) in water or air affected survival of Mexican fruit fly (Anastrepha ludens Loew) larvae. Two tests were conducted with mortality of late third instar Mexican fruit fly larvae evaluated after infested mangoes were immersed in 46.1 °C water for 65, 75, or 90 minutes depending on fruit weight and immediately cooled in water or air at 22 to 26.5 °C. Results suggest a need to amend the current hot water quarantine dip treatment schedule to require cooling of fruit for 30 minutes in air. We suggest a 25-g allowance in maximum permitted fruit weight be established for the 65-, 75-, and 90-minute dips and a monitoring system used to ensure compliance. Synchronization between maximum permitted fruit weight for each hot water dip duration and commercial sizing practices would facilitate monitoring of fruit weight. We also recommend confirmation of efficacy for the 75-minute treatment of flat-elongated mangoes that weigh 375-570 g.

Artificial Infestation

Market demand exists in the United States for fresh mango (Mangifera indica L.) fruit weighing >700 g, yet fruit of this size cannot be imported for lack of a quarantine treatment against fruit flies (Diptera: Tephritidae). Therefore, the objectives of this research were to evaluate the influence of fruit infestation method on mortality of late third instar, fruit fly larvae after fruit were immersed in hot water, and to generate dose mortality and fruit quality data for mangoes >700 g. Results suggested that artificial infestation is preferable to cage infestation because artificial infestation eliminates the direct influence of fruit weight loss on the heat dose delivered to the fruit center. Other advantages of artificial over cage infestation include: fruit maturity at treatment is similar to commercial application, mortality of untreated control fruit can be calculated, larval maturity is uniform and observable, and larvae can be placed into the slowest heating part of the fruit. Infesting with 50 rather than 25 larvae per fruit was preferred because the number of larvae placed into the fruit did not influence mortality and twice as many larvae were evaluated using the same number of fruit. The dose mortality and fruit quality data generated in this research suggest that immersion in water at 46.1 °C for 110 minutes may provide Probit 9 level quarantine security against Mexican fruit fly (Anastrepha ludens Loew) for mangoes weighing up to 900 g without adversely affecting fruit market quality.

Polyols are commonly used in food and medicines as sweeteners and preservatives but may also have insecticidal properties against some species of Diptera. Here we compared the insecticidal activity and feeding response of glycerol and propylene glycol (PG) on two tephritids: Anastrepha ludens and Anastrepha obliqua, and the drosophilid Drosophila suzukii. First, flies were exposed to solutions of 50% sucrose and the two polyols at concentrations of 1.67 M, 2.78 M and 4.18 M for 24 h and then observed at 24 h intervals for a period of three days. Both polyols elicited strong regurgitation behavior in the three flies and killed them. Regurgitation apparently also reduced flies’ body weight, and this was particularly apparent in insects that fed on 4.18 M PG solutions. A high percentage of individuals exposed to PG solutions perished after 72 hours. The number of proboscis extensions, which is associated with feeding preference, was lower in the 4.18 M polyols + sucrose mixtures than in the 50% sucrose solution. Glycerol had a lower insecticidal effect in Anastrepha spp. and very little insecticidal effect in D. suzukii. Finally, elevated regurgitation and mortality was confirmed in A. ludens treated with 1.0–2.78 M of erythritol plus sucrose. Our results demonstrate that PG, and to a lower extent glycerol, have the potential for being used as a safer method of insect pest control. The hyper-regurgitation response may contribute to the insecticidal properties of these polyols in Diptera.
