“…Diet formulation is a key issue in any mass rearing system, as it should guarantee proper insect nutrition at low cost using a practical application method (Hernández et al., ; Cohen, ). The diet for larval fruit fly development is normally prepared by mixing dried Torula yeast, sugar, preservatives, and bulking compounds.…”

The sterile insect technique (SIT) requires the rearing, sterilization, and release of large numbers of insects to induce sterility within wild pest populations. In 1992, the Mexican government launched a national campaign against economically important fruit fly pests, with the aim of establishing free areas and strengthening fruit exports. To achieve these objectives, the Moscafrut facility began operations in 1993 with the mass rearing of Anastrepha ludens (Loew) (Diptera: Tephritidae: Toxotrypanini) and in 2002 with Anastrepha obliqua (McQuart). Field releases of sterile insects began in the north of the country, and currently 51% of the country is free of these pests. In this review, we describe the mass‐rearing process and the quality control tests used in the production of the above‐mentioned species. As a case study, we also describe the achievements of applying the SIT against A. ludens populations in the citrus‐growing zone of the state of San Luis Potosí, which has resulted in dramatic reductions in both wild fly populations and the use of chemical sprays. We discuss the implications, achievements, and perspectives regarding the use of this technology to control Anastrepha pests in Mexico.

“…Gel diets developed in this study could also be used as cost-effective generic diets for rearing other pestiferous Anastrepha spp. [10,49]. Having cost-effective diets for mass-rearing fruit flies becomes particularly relevant under current climate change conditions that is expanding the distribution and host range of pestiferous flies [6,50], as this may require increasing the mass production of artificially-reared sterile flies and parasitoids to protect fruit growing areas that were not previously attacked.…”

The development of cost-effective diets for mass-rearing fruit flies (Diptera: Tephritidae) and their parasitoids in pest control programs based on the Sterile Insect Technique is a high priority worldwide. To this end, we tested carrageenan, agar, gelatin and two types of pregelatinized corn starches as gelling agents at varying percentages in a yeast-reduced liquid larval diet for rearing the Mexfly, Anastrepha ludens. Only diets with 0.234% (w/w) agar or 0.424% carrageenan were identified as diets with potential for mass-rearing A. ludens in terms of the number of pupae recovered from the diet, pupal weight, adult emergence, flight ability and diet cost. Comparative experiments showed that yeast-reduced agar and carrageenan gel diets produced heavier pupae and higher proportions of flying adults than the standard mass-rearing diet. The gel-agar and mass-rearing diets produced more pupae than the gel-carrageenan diet, but the latter produced more suitable larvae as hosts for rearing of Diachasmimorpha longicaudata (Hymenoptera: Braconidae) females, a widely used fruit fly biocontrol agent. Yeast-reduced agar and carrageenan gel diets could represent cost-effective fruit fly mass-rearing diets if a practical system for gel diet preparation and dispensation at fruit fly mass-rearing facilities is developed.

“…The pelleted ready‐to‐use maize cob diet named Nutri‐Fly P‐AL™ was produced by Coltecinter (Guadalajara, Jalisco, Mexico) using the ingredients in the proportions described for A. ludens by Orozco‐Dávila et al (2017). It was used in the current study for both A. ludens and A. obliqua as a generic diet (Hernández et al, 2014). The pelleted‐maize cob diet, Nutri‐Fly PAL, was manufactured especially for experimental purposes by Coltecinter company as the first pelleted prototype diet for mass rearing tephritid fruit flies (Figure 2).…”

“…Most artificial diets for mass‐rearing of fruit fly larvae are prepared in the laboratory, after purchasing and independently weighing each ingredient of the composition. With regard to A. ludens and A. obliqua diets, several formulations and compositions of artificial diets for larvae have been proposed (Moreno et al, 1997; Hernández et al, 2010, 2014, 2016; Rivera et al, 2012). These artificial diets have been used successfully to produce millions of fruit fly pupae per week at the Moscamed and Moscafrut facilities, in Metapa de Domínguez, Chiapas, Mexico – 478, 150, and 62 million of Ceratitis capitata (Wiedemann), A. ludens , and A. obliqua , respectively (Orozco‐Dávila et al, 2017; Senasica, 2017a,b).…”

Most artificial diets used for mass‐rearing of fruit fly larvae involve the purchase and independent weighing of each ingredient of the formulation, followed by mixing and diet preparation process. A ready‐to‐use formulation would avoid this time‐consuming task and simplify the preparation procedure, leading to a more standardized diet. In this work, we compared life‐history traits and survival and developmental parameters of Anastrepha ludens Loew and Anastrepha obliqua (Macquart) (Diptera: Tephritidae) reared on two formulations of an artificial diet. Two experiments were performed; first, a conventional non‐pelleted diet was compared to a newly developed pelleted diet, which was mixed with water before being given to the larvae. The second experiment consisted of a comparison between the pelleted diet which was stirred in a mixer with water and dissolved preservatives and a pelleted diet which was only soaked in water with dissolved preservatives. We found that the pelleted diet allowed the mass‐rearing of A. ludens and A. obliqua. Moreover, feeding larvae with pelleted diet led to increased weight of the larva by 7.4 and 11.8%, and of the pupa by 9.5 and 16.7% for A. ludens and A. obliqua, respectively, compared to conventional diet. For process evaluation, the number of activities, handling time, reception, storage, and larval diet preparation were recorded. The pelleted diet only needed soaking in water containing preservatives, thereby simplifying the mass‐rearing process and saving time, space, and labour. Pelletizing is a versatile technology that can be adjusted for better physicochemical quality and reduced microbiological risk. This diet should be of particular interest for the mass‐rearing process in ‘sterile insect technique’ applications.
