“…Studies have shown that female fruit flies require higher amounts of amino acids than males, because ingestion of amino acids is necessary for maximal egg development (Fontellas & Zucoloto 1999;Cresoni-Pereira & Zucoloto 2001;Aluja et al 2001). Those studies support the findings of Arredondo et al (2014) and Díaz-Fleischer et al (2009), which found greater attraction of A. obliqua females to different protein attractions in field trials than males of the same species.…”

“…Accordingly, it may be that the high protein content of the hydrolysed yeast (FN) in our study (Figure ) was responsible for increased egg–larval duration, reduced pupal weight and a drastic reduction in pupal number in 3FN:1LB and 1FN:0LB diets. Overall, although amino acids are essential for larval development (Chang, ), fruit fly larvae might prefer yeasts with optimal quantity or combination of amino acids (Cresoni‐Pereira & Zucoloto, ), less protein, and maybe more carbohydrate and fat (Chang et al., ; Ekesi et al., ). High nutrient concentration in larval diets does not necessarily improve the performance of diets in productivity or fly quality (Pascacio‐Villafán et al., ) and may result in reduced productivity and fly quality or increased waste.…”

Queensland fruit fly, Bactrocera tryoni (“Q‐fly”), is Australia’s most economically important insect pest of horticultural and commercial crops especially in the eastern regions. The sterile insect technique (SIT) has been adopted as an environmentally benign and sustainable approach for management of Q‐fly outbreaks. High‐performance larval diets are required to produce the millions of flies needed each week for SIT. Yeast products contribute amino acids (protein) to fruit fly larval diets, as well as carbohydrate, fat and micronutrients, but there can be substantial variation in the nutritional composition and suitability of yeast products for use in larval diets. Gel larval diets have recently been developed for large‐scale rearing of Q‐fly for SIT, and composition of these diets requires optimization for both performance and cost, including choice of yeast products. We assessed performance of Q‐flies reared on gel larval diets that contained debittered brewer’s yeast (Lallemand LBI2240), hydrolysed yeast (Lallemand FNILS65), inactivated brewer’s yeast (Lallemand LBI2250) and inactivated torula yeast (Lallemand 2160‐50), including blends. Q‐flies performed poorly when reared on diets containing only or mostly hydrolysed yeast in terms of pupal number, pupal weight and percentage of fliers. Performance was also poor on diets containing high proportions of torula yeast. Overall, debittered brewer’s yeast is recommended as the best option for Q‐fly gel larval diet, as it is cheap, readily available, and produces flies with good performance in quality control assays. Inactivated brewer’s yeast produced flies of comparable quality with only a modest increase in cost and would also serve as an effective alternative.

“…Above this concentration, the percent of matings showed a decreasing tendency. We did not test greater yeast concentrations because our own unpublished observations and results by Cresoni‐Pereira and Zucoloto (2001) on A. obliqua have indicated that these adversely affect survival.…”

The effect of post‐teneral diets on the mating performance, pheromone production and longevity of sterile Anastrepha ludens and Anastrepha obliqua fruit flies (Diptera: Tephritidae) was investigated. Enriched pre‐release diets improved male mating performance. Wild and sterile males fed on mango and orange fruits achieved the greatest copulatory success, followed by those fed on a 3 : 1 sugar : yeast (SY) diet. Males fed only on a sugar diet achieved the lowest number of matings. The mean numbers of copulas achieved by wild males were significantly higher than those by sterile males fed on a sugar‐only diet, while there were no significant differences between wild males and sterile males fed on yeast diets. There was a trend of reduced mean number of copulas as the proportion of yeast was reduced in the diet, but differences were not significant. Pre‐release diets had a significant effect on pheromone production. Males fed on a 3 : 1 SY diet produced the greatest amount of the three main pheromone components in A. ludens males and two major components in A. obliqua males, followed by males fed on fruits or pasteurized fruit juice. Males fed on a sugar only diet produced the lowest amounts. The longevity response to post‐teneral diets was complex. The most yeast‐rich diet and the poorest diet (sugar only) resulted in the lowest life expectancies. Flies fed on 24 : 1 SY diets showed the highest life expectancies for both males and females of the two species. Considering the tradeoffs between mating performance and longevity, the 24 : 1 SY diet would be recommended for programmes integrating the sterile insect technique, but the effects of these diets on field survival and dispersal still need to be investigated.
