After repeated sampling tests, the results (Table 5) indicate that the mealybugs are rich in inorganic salts, and the trace element content may vary depending on the type of feed and the place of origin. If appropriate amount of sodium selenite is added to the feed, absorption by the parasites can be converted into biological selenium, so that selenium-enriched foods can be produced quantitatively. It can also be seen from Table 5 that the beneficial elements contained in insects such as zinc, copper, and iron are higher than conventional foods.
