“…Optimization of temperature, the number of flies in a cage, and photoperiod resulted in increased egg production and reduced adult mortality (Berkebile et al., ) for the adult colony of the mass‐rearing facility. These same optimized conditions had a positive effect on male size as well as mating competence and competitiveness (Pitti et al., ).…”

New World screwworms, Cochliomyia hominivorax (Coquerel) (Diptera: Calliphoridae: Chrysomyinae), are devastating pests of warm-blooded animals that cause significant economic damage to livestock. The successful campaign to eradicate screwworms from continental North America, led by the US Department of Agriculture and using the sterile insect technique, continues to receive research support that has resulted in improved technologies for all aspects of the program. The process and ingredients for mass-rearing screwworms is more efficient and sustainable, and there is now a standardized protocol for developing new strains used in mass rearing. Cryopreservation of screwworm embryos allows strains to be preserved and recovered if necessary and also reduces rearing requirements for backup and research strains. Sterile fly release procedures and equipment have been updated leading to optimized sterile fly release rates. Surveillance for screwworm infestations and outbreaks have incorporated new trap designs, habitat analysis, and molecular genetic techniques that enhance monitoring the progress of the program as well as early detection and response to outbreaks. Genetic analyses of screwworm populations across their current range have increased the understanding of genetic differentiation, which may aide in developing new strains and determining the geographic origin of screwworms causing outbreaks when they occur. The ability to release only sterile males, which has been a goal of the program for over 60 years, has recently been accomplished through the development of transgenic sexing strains. The strains carry a conditional female lethal gene and are comparable to the wild-type strain for several biological parameters that are important for mass production and performance in the field. The strains should improve efficiency of population suppression of the current and future eradication and prevention programs against screwworms. These research advances as well as future considerations are presented.

“…There are two issues with these parameters used in the screwworm research: (i) measuring these parameters is time‐consuming and some of them may be highly correlated; and (ii) none of the parameters directly indicates the quality of males in relation to their performance in field eradication programme (Pitti et al. ).…”

The New World screwworm, Cochliomyia hominivorax (Coquerel) (Diptera: Calliphoridae), has been eradicated from North and Central America using the sterile insect technique. This success has been based on mass production of high-quality screwworms using artificial diets since 1958. Many diet formulations for both larvae and adults have been developed, mainly driven by cost efficiency and material supply. However, only four larval and two adult diet formulations have been applied in the six sterile fly mass production plants in the USA, Mexico and Panama. Herein, we briefly review the history of screwworm diet research and development, introduce the diet formulations used in mass rearing and discuss their advantages and disadvantages in terms of plant application. Finally, we propose future research on screwworm nutrition, potential protein sources, feeding stimulants, further optimization of screwworm formulations and possible methods to reduce the negative qualities of waste generated during the mass production.

“…While the ‘LengthOpt’ model allowed for the highest retention of males, it also led to an average of 70% of female pupae ending up in the throughput, thus reducing the MFR. The ‘Ridge’ model had the highest mean FER; however, despite its ability to remove an average of 91% of females from a sieved sample, the male recovery was too low and would lead to the loss of many of the larger, potentially more competitive males . The mass‐rearing output would have to be increased significantly to produce enough throughputs for irradiation, making the process highly inefficient.…”
