The overpopulation of the planet in combination with the depletion of resources will inevitably lead to mass starvation, so scientists are now looking for alternative sources of food. One of the most promising are the insects and especially their larvae: they contain huge amount of protein, and, moreover, they are very easy to breed. But in order to extract from them the maximum amount of nutrients, they themselves must be fed properly. This task is being solved by the experts from Georgia Institute of Technology.
For experiments was taken the black linki (lat. Hermetia illucens). These flies lay about 600 eggs from which develop larvae up to a length of 27 mm and a weight of about 0.22 g. They are characterized by their ability to absorb practically any organic waste accumulating in your body a complex of macro – and micronutrients. Now they are used for feeding farm animals, but they contained proteins, fats and other substances are also suitable for man. To understand exactly how the larvae feed on black livinec, scientists put them on a pizza and turned on the video camera.
The pizza was destroyed in two hours, while the larvae showed amazing technique – “the fountain”. While some larvae absorb food, others are trying to break through to her, they do it, they throw chewing relatives and bite into pizzas, while the next layer of the hungry larvae will not reject them, and the process only ends with the disappearance of the food source.
This is a very effective way of feeding: it allows you to get enough of the greatest number of individuals. Other animals, including scavengers, do not touch each other when feasting at the same time.
While collective efforts to help the larvae as quickly as possible to get to the soft and high-quality food: if pizza once was hollowed crust, larvae have focused on soft cheese, ignoring the crusty bread.
But another alternative source of food, besides insects, can become air.
