“…The same is true for yellow mealworms; data from several studies suggest similar concentrations of Fe (3·3-10·0 v. 3·7-8·9 mg/ 100 g DM) and Zn (9·5-13·7 v. 11·3-14·4 mg/100 g DM) for larvae and adults, respectively (19,20,22,(24)(25)(26)31) .…”

Dietary deficiencies in Fe and Zn are globally widespread, causing serious health problems such as anaemia, poor pregnancy outcomes, increased risk of morbidity and mortality, stunted growth and impaired physical and cognitive development. Edible insects, of which a diversity of over 2000 species is available, are dietary components for about 2 billion individuals and are a valuable source of animal protein.In the present paper, we review the available information on Fe and Zn in edible insects and their potential as a source of these micronutrients for the rapidly growing human population. The levels of Fe and Zn present in eleven edible insect species that are mass-reared and six species that are collected from nature are similar to or higher than in other animal-based food sources. High protein levels in edible insect species are associated with high Fe and Zn levels. Fe and Zn levels are significantly positively correlated. Biochemically, Fe and Zn in insects occur predominantly in non-haem forms, bound to the proteins ferritin, transferrin and other transport and storage proteins. Knowledge gaps exist for bioavailability in the human alimentary tract, the effect of anti-nutritional factors in other dietary components such as grains on Fe and Zn absorption and the effect of food preparation methods. We conclude that edible insects present unique opportunities for improving the micronutrient status of both resource-poor and Western populations.

Inhabitants of the Indonesian island of Sumatra are faced with the problem of insufficient food supplies and the consequent risk of undernourishment and health issues. Edible insects as a traditional and readily available food source could be part of the solution. The nutritional value of insects depends on many factors, e.g., species, developmental stage, sex, diet, and climatic conditions. However, edible insects bred in Sumatra for human consumption have never before been assessed with regard to their nutritional value. Our study involved analyses of crude protein, chitin, fat and selected fatty acid contents of giant mealworm larvae (Zophobas morio), larvae of the common mealworm (Tenebrio molitor) and nymphs of the field cricket (Gryllus assimilis). Crude protein content in the samples ranged from 46% to 56%. Highest (35%) and lowest (31%) amounts of fat were recorded in giant mealworm larvae and larvae of the common mealworm, respectively. Chitin amounts ranged from 6% to 13%. Based on these values, which are comparable to those known from other food insects reared in different regions of the world, the edible species bred in Sumatra could become food sources with a potential to help stave off hunger and undernourishment.

“…S. gregaria is a very important agronomic pest but presents also many possibilities in terms of food production with an average of 76% of protein content [40]. Our most important inding is that desert locust polyphenism may be induced by multiple matings that act as a signal of phase shift.…”

“…As this species is usually consumed by human population [40] and may even be a source of dietary or therapeutic sterols [41], a beter knowledge of its mating strategies may improve possible mass rearing systems.…”

The multiple mating by female (polyandry) is a widespread behavior in insect species. This behavior is known to be a kind of itness maximization, but some case of sexual selection factors can explain the evolution of this behavior in relation with the phenotype plasticity model. In this paper, we analyze the role of polyandry in the reproductive success and in the phase shift process in the gregarious desert locust. In an applied perspective, knowledge on the reproductive success and in the phase shift process is essential to perform mass rearing for human food production. Our results suggest that multiple mating is not associated with itness beneits. Polyandry acts as a signal of phase shift through ofspring. We showed that hatchlings of gregarious females mated only once are smaller and green at 87.2% in irst egg pods and produced the solitary form of the desert locust. The coloration of ofspring in females mated with two males reaches only 15.2% of green forms versus 84.8% of mostly blacks. In this study, we showed that females mated more than two times with diferent males produce larger eggs, heavier, and black hatchlings characteristic of gregarious phase known in S. gregaria.
