The projections for the production of insects as food and feed show an enormous increase for insect production in the near future, which will subsequently lead to the increase of the stored quantities of insect meals and related products. However, information on the susceptibility of insect meals to infestations by stored-product insects is rather limited. To this end, the objective of the present study was to evaluate the potential of major storage insect species to grow and reproduce on insect meals that are based on larvae of the lesser mealworm,Alphitobius diaperinus. The progeny production of thirteen stored-product insects onA. diaperinusmeal, as well as their instantaneous rate of increase, as a measure of population growth, was recorded for each species. Based on the results, six out of the thirteen examined insect species (A. diaperinus,Tenebrio molitor,Trogoderma granarium,Lasioderma serricorne,Tribolium confusum, andTribolium castaneum) were able to infest pureA. diaperinusmeal, as they grew well and developed progeny on the insect meal substrate.Tribolium confusum,T. castaneum, and especiallyT. granariumgave the highest progeny production numbers in theA. diaperinusmeal with the latter giving an instantaneous rate of increase of 0.067. Expecting the upcoming increase in the production of insect-based products globally, further research in this field is needed for improved production and storage facilities, detection and estimation methods, and technologies to minimize insect infestations without causing negative effects to farmed insects.
