The Mexican fruit fly Anastrepha ludens Loew (Diptera: Tephritidae) is one of the most important insects infesting mangoes, citrus, and other fruits in Mexico and other Latin-American countries. Quarantine methods approved to destroy this insect decrease the shelf life of commodities. The objective of this study was to determine the effect of high-pressure processing using an initial temperature of 50 degrees C on the survivorship of eggs and larvae of the Mexican fruit fly. Eggs and larvae were pressurized at 25, 50, 75, 100, or 150 MPa for 0, 5, 10, or 20 min. The hatching ability of pressurized eggs of 1, 2, 3, and 4 days old and survivorship of the first, second, and third instars were registered. Further, the ability to pupate was studied in surviving third instars. The results showed that eggs were more resistant than larvae to the high-pressure processing. Treatments at 150 MPa at initial 50 degrees C for 10 min destroyed all eggs and larvae of A. ludens, indicating that this process might be useful as a quarantine method for infested mangoes or other fruits.
墨西哥实蝇 Anastrepha ludens Loew（双翅目：实蝇科）是一种重要的昆虫，会侵害墨西哥和其他拉丁美洲国家的芒果、柑橘和其他水果。为了消灭这种昆虫而批准的检疫方法会降低商品的保质期。本研究的目的是确定使用初始温度为 50°C 的高压处理对墨西哥实蝇卵和幼虫存活的影响。将卵和幼虫在 25、50、75、100 或 150 MPa 的压力下处理 0、5、10 或 20 分钟。记录了加压后 1、2、3 和 4 天龄的卵的孵化能力以及第一、第二和第三龄幼虫的存活率。此外，还研究了幸存的第三龄幼虫化蛹的能力。结果表明，卵比幼虫对高压处理更具抵抗力。在初始 50°C 下用 150 MPa 处理 10 分钟可杀死所有 A. ludens 的卵和幼虫，表明该过程可能可用作受感染芒果或其他水果的检疫方法。
