**2.2 Edible insects as protein source**

*Acheta domesticus, A. mellifera* (honeybee), *Bombyx mori* (farmed silkworm), *Imbrasia belina* (mopane caterpillar), *Tenebrio molitor* (yellow meal worm), and *Rhynchoporus phoenicis* (African palm weevil) are the six most prevalent commercial edible insect species at the moment. The edible ratio of different orders is shown in **Figure 2**. Only the larvae of several species (*R. phoenicis*, *T. molitor,* and *I. belina*) are frequently ingested, as their rich lipids can produce a fascinating flavor. Because of its vigor, *T. molitor* production has been mechanized [9]. Only the adults of orthopterans, such as crickets, are commonly consumed. Swarming makes them extremely effortlessly harvest. Although, because they are common pests in most locations and are frequently exposed to pesticides throughout their lives, there is concern that may compromise food safety, which is the presence of latent pesticides.

Ingesting insects in a responsible and healthy manner has become a popular way to alleviate poverty. Insects that are edible play a vital part in a variety of food systems. In fact, in many underdeveloped countries, they have provided a critical supply of
