Sustainable approach to polystyrene management and bioinsecticide production: Biodegradation by Tenebrio molitor larvae co-fed with residual biomass and bioactivity of frass pyrolysis bio-oil against insect pests.

Tenebrio molitor has gained attention as a potential solution for plastic pollution. This study explored the biodegradation of polystyrene (PS) by mealworms co-fed with rice bran (RB) under an optimized rearing scheme. The RB co-diet significantly increased PS consumption by two-fold compared to wheat bran (WB).

From waste to food and bioinsecticides: An innovative system integrating Tenebrio molitor bioconversion and pyrolysis bio-oil production.

To achieve a waste-free clean production, the present study aimed to valorize an underused agroindustrial byproduct (rice bran) by mealworms bioconversion and produce bio-oil from pyrolysis of insect excreta (frass) as bioinsecticide. To reach the first goal, the suitability of rice bran (RB) versus standard diet, wheat bran (WB), was examined by determining feed conversion, growth performance, and nutritional profile of T. molitor larvae.

Development and characterization of nanoemulsions loaded with essential oil and β-cypermethrin and their bioefficacy on insect pest of economic and medical importance.

Background: The development of novel and ecofriendly tools plays an important role in insect pest management. Nanoemulsions (NEs) based on essential oils (EOs) offer a safer alternative for human health and the environment. This study aimed to elaborate and evaluate the toxicological effects of NEs containing peppermint or palmarosa EOs combined with β-cypermethrin (β-CP) using ultrasound technique.
