Phytochemical-based nano emulsions for stored grain protection:

摘要: Stored grain losses caused by pest insects contribute significantly to the global food crisis. Currently, there are two main chemical control methods against stored product insect pests: fumigation with very toxic gases and protection residual contact insecticides. Today, tendency is prevent/reduce wide use of insecticides, which have high toxicity humans harm environment. Therefore, an urgent need develop alternative eco-friendly approaches for control. Essential oils from Micromeria fruticosa Mentha rotundifolia (Fam. Labiatae) their constituent pulegone previously were shown us as active pests, encapsulated into coarse nano emulsions. The insecticidal activity developed formulations primary internal rice weevil (Sitophilus oryzae L.) secondary external red flour beetle (Tribolium castaneum Herbst) was evaluated in laboratory pilot experiments. It found that phytochemical-based emulsions offered significant advantages provided powerful prolonged biological compare formulations. could serve a natural, effective, low-toxify human, environmentally preferred method dry products insects.
