Stable flies can be found developing in a broad variety of substrates in nature and can be reared in many types of media in the laboratory. We have used wood shavings and vermiculite as bulking agents. Vermiculite worked well, but made separating puparia from rearing medium difficult and was expensive (~$0.60/pan). Possibly because of the added rigor of separating puparia from the medium, eclosion was also lower with vermiculite, 57% vs. 75% for wood shavings. Cottonwood shavings were comparable to vermiculite, but at ti...

Stable flies, Stomoxys calcitrans (L.), are hematophagous flies whose painful bites disrupt the grazing behavior of livestock, cause pain and suffering to companion animals and disrupt human recreational activities worldwide. Immature stable flies develop in fermenting vegetative matter, often contaminated with animal waste. Changing agronomic practices and crops have produced serious outbreaks of stable flies in crop residues, vegetables in Australia1, sugar cane in Brazil2, and pineapple in Costa Rica3. Although just 14 stable flies per animal are considered to be the economic threshold4, observations of more than 2,000 flies per animal have been made during recent outbreaks5. Such infestation levels reduce host productivity to near zero and can cause mortality6. As a result of agronomically associated outbreaks, stable flies are receiving renewed interest and demand for laboratory colonies has increased dramatically.
As for all holometamorphic insects, stable flies obtain all of the nutrients required for growth during the immature or larval stage. Therefore, an important component of a rearing system is the larval diet or substrate. Stable fly larvae have been observed developing in a broad range of substrates in the field7 and they are dependent upon the microbial community of the substrate8,9. Natural larval substrates are primarily composed of decomposing or fermenting vegetative materials often contaminated with nitrogenous wastes.
For laboratory rearing, stable fly larval substrates are usually composed of a vegetative material and an added nitrogen source. Numerous materials have been used for stable fly larval diets. The first larval diets mimicked natural substrates and included fermenting oat straw and horse or cow manure10,11. Carbohydrate sources include wheat bran12,13,14, alfalfa meal12,13,14 and a commercial formulation developed by Chemical Specialties Manufacturers Association (CSMA, 33% wheat bran, 27% alfalfa meal, 40% brewer&#39;s yeast granules)13,14,15,16. Nitrogen sources include yeast suspension12, fish meal and ammonium bicarbonate17. Inert bulking materials are often included in diets including oat hulls12, bagasse13, vermiculite16, wood chips13,18 and pelleted peanut hulls14.
A primary objective of laboratory rearing is to produce a product that is as physiologically similar to &#34;wild type&#34; as possible in order that laboratory experiments will produce results reflecting those of field populations. This requires that in-breeding and selection be minimized to maintain genetic diversity and nutritional resources be comparable to those in the field. Secondary objectives are to minimize labor and expenses. A major component of minimizing expenses is the use of locally available diet components. The stable fly rearing system presented was developed to meet these objectives.

laboratory rearing of stable flies and other muscoid diptera

Stable flies, Stomoxys calcitrans, are serious pests of livestock, humans, companion animals and wildlife worldwide. During the last 20+ years, changes in agronomic practices resulted in serious outbreaks of stable flies in several countries. These outbreaks disrupted livestock production and human recreation resulting in public demands for increasing research and management efforts for this pest. A simple and inexpensive procedure for rearing stable flies for laboratory studies is presented. The procedure uses locally available diet components, equipment and supplies. The procedure can be adapted for rearing other muscoid flies including face fly (Musca autumnalis), horn fly (Haematobia irritans), and house fly (Musca domestica). The procedure produces stable fly puparia averaging 12.5 mg and ~35% egg to adult survival. Approximately 3000 flies are produced in each pan.

Larvae pupariate 10&#8211;14 days and adults emerge 14&#8211;16 days after oviposition. Generation time, egg to egg, is ~24 days. Rearing data for May 2013 to January 2017 with three different bulking agents and two colonies are presented in Figure 5. Cottonwood gave the best yield, 3867 &#177;1442 (<img alt="Equation" src="/files/ftp_upload/57341/57341eq1.jpg" /> &#177; standard deviation) pupae weighing 12.5 &#177;1.6 mg with 74 &#177;19% eclosion producing...
