Abstract
Locusts are often considered as humans’
nuisances and crop pests, despite evidence that they are high in protein and
maybe consumed by animals. They have generally been overlooked. However, the
current increase in entomophagy has been partly attributed to the nutritional
value of insects, which is important, especially when considering the global
scarcity of dietary sources. At the same time, locusts are rich in nutrients
and can be mass-produced sustainably. Purpose of this study was to determine
the chemical composition, nutritional and mineral content (macro and micro),
and the heavy metal elements of migratory locusts (Locusta migratoria
(L.), Orthoptera: Acrididae) at various metamorphic stages in
newly emerged nymphs of the 4th and 5th instars, as well
as immature adults (IA) and mature adults (MA). Crude protein (CP), ether
extract (EE), total carbohydrates (TC), crude fiber (CF), ash, energy, dry
matter (DM), and moisture were all measured as percentages. The macro and micro
minerals content were determined, macro-mineral as (calcium (Ca) g/100g,
phosphorus (P) g/100g, magnesium (Mg) g/100g, potassium (K) g/100g, and sodium
(Na g/100g), micro minerals as (iron (Fe) g/100g, copper (Cu) mg/kg, manganese
(Mn) mg/kg, Zinc (Zn) g/100g, boron (B) mg/kg, and cobalt (Co) mg/kg, nickel
(Ni) and chromium (Cr) were measured. Selenium (Se), lead (Pb), mercury (Hg),
arsenic (As), and cadmium (Cd) were all undetectable in samples.
