Rumor names Egypt but, although the fresh waters of Egypt are replete with curious and beautiful dwarf fishes and the Egyptians developed the art of glass blowing during the Ptolemaic and Roman periods, after 300 B.C., there is no evidence that vessels of glass were used for aquaria. It would be interesting to know in what country little fishes were first placed in glass receptacles for purposes of esthetic enjoyment. This article was originally published in the National Geographic Magazine of March 1931 and is presented for historical interest! More Than 600 Varieties of Aquarium Pygmies Afford a Fascinating Field for Zoological Study in the Home This way, the flies will just crawl out and get caught. It is also possible, in a glass covered terrarium, to place a screen over the culture. With herptiles you can also release a number of the flies as a meal. Biological supply houses also sell them, but are generally very expensive.įor fish, just pour a quantity of the adults on the surface of the water. WINGLESS Drosphila starter cultures are available from fish club members, friends at High Schools and Colleges, and by mail order from companies listed in aquarium magazines. The adults and larvae just use the sides of the jar. I’ve found this to be unnecessary and an added complication when harvesting. Many suggest placing some sort of stiff plastic in the jar as a roost for the flies and as a surface for the larvae to pupate on. NORMAL fruit flies will wind up all over the house! Also, if the Fruit Flies escape, the WINGLESS won’t get very far. With WINGED you have to knock them out with ether or deal with them flying all over the place. With the WINGLESS flies you just tap the jar until they fall to the bottom and then pour them into new media. The WINGLESS fruit flies are easier for your pets to catch and are very convenient to transfer from culture to culture. Make sure you get the WINGLESS and not the VESTIGAL WINGED, for the latter will produce normal phenotype WINGED progeny under various environmental conditions. Your best bet is to obtain a culture of WINGLESS Drosophila. The jars must be very clean, preferably sterile, or you will be culturing a host of molds, instead of fruit flies! Cover the tops with a piece of paper toweling held in place by a rubber band. Sprinkle a pinch of dried yeast on the surface of the mash. Pour in water to the same level as the potato-sugar. Add one inch of this blend to a wide mouth jar. Mix one tablespoon of sugar with one cup of dried instant mashed potatoes, available from any supermarket. You can also culture fruit flies indoors. Your birds will occupy themselves by hunting for the insects, as they would in the wild. This will provide as much psychological as nutritional benefit. The culture will yield a steady supply of flies. As long as the air temperature is generally above sixty degrees, wild fruit flies will soon appear. If the birds get at the mess they will certainly soil their plumage and possibly consume the tainted fruit with no good result. The screen keeps the birds out of the foul mash. This size lets the flies in to breed and the progeny out for the birds to eat. The container must be covered with quarter inch wire mesh. It is important that the fruit has gone bad, for Drosophila can’t colonize fresh produce. In an outdoor aviary you can take a bucket and throw in several pieces of rotting fruit. To anoles, young pantodon bucholzi, tree frogs, red efts etc!įruit Flies (Drosophila sp.) Are a valuable food for many birds, fish, and herptiles.
