Breeding:<\/h2>\n\n
Breeding these animals is very easy and very inexpensive compared to other animals. I use washable glass containers or plastic containers with a capacity of 500-1000 ml for breeding. I fill them with the breeding substrate to a height of approx. 3 cm. Wood wool, egg cartons, crumpled paper or strips of paper from the shredder are placed on the substrate as a walking surface. As a rule, I stock the new breeding boxes with 20-40 flies, so that the larvae are stocked quickly. I do not heat the fruit fly hatchery but keep it at normal room temperature. <\/p>\n\n
You should therefore keep the breeding cultures a little warmer and the containers with the already hatched animals a little cooler to increase their lifespan. Egg laying is best observed shortly after the cultures have been prepared, when the larvae are not yet disturbing. The eggs are preferably laid on the surface of the culture medium. The development period depends on the temperature. <\/p>\n\n
During larval development, the animals moult twice. The length of the animals increases. The larvae burrow into the culture medium. To pupate, they usually leave the culture medium and migrate up the wall of the breeding containers. <\/p>\n\n
Nutrient medium:<\/h2>\n\n
Drosophila larvae feed on yeasts. The culture medium must be such that it provides favorable growth conditions for yeasts. It should be firm enough so that nothing flows out when the container is turned over. However, the larvae must be able to bore into the substrate. <\/p>\n\n
Ingredients for a breeding container in summer:<\/h3>\n\n\n\n\n- 1 cube of baker’s yeast (1 packet of dry yeast)<\/strong><\/li>\n\n\n\n
- 2 teaspoons sugar<\/strong><\/li>\n\n\n\n
- 100 ml fruit vinegar (6 tablespoons)<\/strong><\/li>\n\n\n\n
- 40 g rolled oats (3 heaped teaspoons)
Ingredients for a breeding container in winter:<\/h3>\n\n\n\n\n- 1 cube of baker’s yeast (1 packet of dry yeast)<\/strong><\/li>\n\n\n\n
- 1 tablespoon sugar<\/strong><\/li>\n\n\n\n
- 135ml vinegar (8 tablespoons)<\/strong><\/li>\n\n\n\n
- 1 bag of mashed potatoes<\/strong><\/li>\n\n\n\n
- Water (half of the liquid indicated on the packaging)<\/strong><\/li>\n<\/ul>\n<\/div>\n<\/div>\n\n
You do not need an antifungal agent such as Nipagin as the proportion of vinegar is very high. You can also leave out the yeast, as there are yeast cells on the feet of the breeding flies. However, this delays breeding considerably. Due to the presence of yeast, it must be clear to everyone that completely odorless breeding is not possible. In the beginning, the smell of vinegar predominates. The longer the culture stands, the more unpleasant the smell of the substrate becomes. <\/p>\n\n
