  • not just popular spices essential oils from cuminum cyminum and Pimpinella anisum are toxic to insect pests and vectors without affecting non target invertebrates
    Industrial Crops and Products, 2018

    Abstract:

    Abstract Each year the flavor and fragrance industry produces more than hundred thousand tons of essential oils. An important portion of this production might be directed to the fabrication of green pesticides relying on the well-documented efficacy of many essential oils against insect pests as well as vectors, besides their safety for human health and the environment. In this regard, two popular spices of economic importance, such as cumin (Cuminum cyminum) and anise (Pimpinella anisum), which are not only cheap, readily available, generally recognized as safe (GRAS), but also produces larger amounts of essential oils, are gaining interest for botanical insecticide development. Herein, we evaluated the efficacy of the essential oils obtained from seeds of these two spices on two agricultural pests, i.e., the peach-potato aphid Myzus persicae and the tobacco cutworm Spodoptera littoralis, and on two insect vectors, i.e., the common housefly Musca domestica and the lymphatic filariasis and Zika virus vector Culex quinquefasciatus. Furthermore, their safety on beneficial organisms such as the earthworm Eisenia fetida and the aphid predator Harmonia axyridis was assessed. The two essential oils, characterized by γ-terpinen-7-al (35.3%), cumin aldehyde (21.8%), and α-terpinen-7-al (15.4%), and (E)-anethole (93.0%), respectively, showed noteworthy effects against all pest targets, with anise more effective on larvae of C. quinquefasciatus (LC50 = 25.4 μl L−1) and S. littoralis (LD50 = 57.3 μg larva−1), whereas cumin was more active on adults of M. persicae (LC50 = 3.2 ml L−1) and M. domestica (LD50 = 31.8 μg adult1). Moreover, when compared at sub-lethal concentrations with the commercial insecticide α-cypermethrin, they were definitely devoid of toxic effects on E. fetida and H. axyridis. These results represent a milestone to manufacture and commercialize green formulations to be used in crop protection and to combat insect vectors of public importance.

  • Pimpinella anisum essential oil nanoemulsions against Tribolium castaneum—insecticidal activity and mode of action
    Environmental Science and Pollution Research, 2018
    Co-Authors: Ahmed S Hashem, S S Awadalla, Gamal M Zayed, Filippo Maggi, Giovanni Benelli
    Abstract:

    The red flour beetle, Tribolium castaneum Herbst (Coleoptera: Tenebrionidae), is an economically important pest of stored products. As possible alternative to conventional insecticides for its management, plant essential oils have gained interest owing to their effectiveness and eco-friendly features. However, they also show some drawbacks, such as low stability, poor water solubility and diffusion, and limited persistence in the environment. A good strategy to overcome these disadvantages is represented by green nanotechnologies. Herein, we developed a nanoemulsion based on the essential oil from Pimpinella anisum L. (Apiaceae) containing 81.2% of ( E )-anethole and evaluated its toxicity on T. castaneum adults and F_1 progeny, as well as its morphological and histological impact. The aniseed oil nanoemulsion was characterized by the formation of a semi-solid interphase between oil and water; mean drop size was 198.9 nm, PDI was 0.303, zeta potential was − 25.4 ± 4.47 mV, and conductivity was 0.029 mS/cm. The nanoemulsion showed toxicity on T. castaneum (LC_50 = 9.3% v / v ), with a significant impact on its progeny. Morphological and histological damages triggered by feeding and exposure to the aniseed nanoemulsion were analyzed by scanning electron microscopy (SEM) and light microscopy. Overall, our findings showed that the development of nanoemulsions allows to improve the stability of P. anisum essential oil enhancing its efficacy against stored grain pests and contributing to reduce the use of harmful synthetic insecticides.
