Strain effect on the development and mating compatibility of Tenebrio molitor L. (Coleoptera: Tenebrionidae)


Abstract: The yellow mealworm, Tenebrio molitor L. (Coleoptera: Tenebrionidae), is a
secondary insect pest of stored products. Most research on T. molitor has been directed to its
nutritional requirements, as well as to the optimum rearing environmental conditions. However, a few published data also reveal that genetic material affects economically important life table characteristics, towards the effect of strain on life table characteristics and infestation patterns. In this context, the aim of our study was to evaluate larval development and adults’ performance of seven T. molitor strains (i. e., Greek, Turkish, German, USA, Spanish and two Italian strains), as well as the mating compatibility among different strains.
