“…The 2 nd generation showed low values for the percentage of ying insects, due to the reduction in the percentage of insect emergence, while in other generations, the percentage of ying insects reached values above 70%. Resilva et al (2014), working with B. philippinensis for 12 generations on a liquid diet, also obtained high rates of variation in the percentage of ying insects, from 40.2 to 93.2%. In the present study, even though radiation doses were not tested, it is possible to extract results that could be used for rearing insects using the sterile insect technique (SIT).…”

Anastrepha fraterculus (Diptera: Tephritidae) is considered an important pest in Neotropical countries. The laboratory rearing of this species should reproduce conditions in nature; thus, special attention is required to the nutritional quality of diets for larval development. Protein components (wheat germ) are costly and account for most production costs in lab insect rearing. In this sense, this work aimed to identify ingredients to replace wheat germ, without compromising diet quality for the lab rearing of A. fraterculus. We tested diets composed of whole rice flour, corn flour, and a mixture of whole wheat flour + soybean flour as substitutes for wheat germ as well as a raw wheat germ diet, considered as the control. The protein sources used in the larval diet influenced the biological performance of both the larval and adult stages of A. fraterculus during six generations. The diet containing corn flour and wheat germ showed similar results in the different developmental parameters. The diet with rice flour also provided adequate biological development for A. fraterculus throughout its life cycle and was nutritionally similar to the control. As it is local product, rice flour can replace wheat germ (costly imported product) in artificial diets for A. fraterculus, reducing production costs by roughly 30% without compromising the biological and nutritional parameters of the insects. Our findings provide basis to improve mass rearing of A. fraterculus for the biological control as parasitoids and in the sterile insect technique, sustainable management strategies currently implemented in the management of A. fraterculus.

“…An average value above 75% was reached only from the 43 rd generation onward. Resilva et al (2014) working with Bactrocera philippinensis (Drew and Hancock 1994) (Diptera: Tephritidae) on a liquid diet for 12 generations also reported wide ranges of variations, around 41.6 and 86.6% for egg hatch percentage.…”

“…The gel diets of Moadeli et al (2017) were based on liquid diet formulations of Chang, Vargas, Caceres, Jang, and Cho (2006) and Chang (2009a), retaining the original nutritional composition but suspending these materials in an agar matrix. Chang et al (2006) liquid diet contains inactivated brewer's yeast, while Chang (2009a,b) liquid diet contains a 3:1 mixture of debittered brewer's yeast (Lallemand LBI2240) and hydrolysed yeast (Lallemand FNILS65; for implementation of these liquid diets, see Chang et al, 2006;Chang, Caceres, & Ekesi, 2007;Chang, 2009a,b;Khan, 2013;Ekesi, Mohamed, & Chang, 2014;Resilva, Obra, & Chang, 2014). We investigated the potential of four yeast types-debittered brewer's yeast (Lallemand LBI2240; $7.55/kg), hydrolysed yeast (Lallemand FNILS65; $26.50/kg), inactivated brewer's yeast (Lallemand LBI2250; $12.46/kg) and inactivated torula yeast (Lallemand 2160-50; $28/kg) used alone or in combination as alternatives for the yeasts used in gel larval diets of Moadeli et al (2017).…”

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.
