Developing green insecticides to manage olive fruit flies? Ingestion toxicity of four essential oils in protein baits on Bactrocera oleae
2020
Abstract Effective and eco-friendly plant-borne insecticides for developing lure and kill control tools against tephritid flies are scarce. Herein, the activity of four essential oils (EOs) obtained from two Apiaceae, Pimpinella anisum L. and Trachyspermum ammi (L.) Sprague, and two Lamiaceae, Thymbra spicata L. and Ocimum gratissimum L., was evaluated against the olive fruit fly, Bactrocera oleae (Rossi), a key pest of olive groves. The EO chemical composition was determined by gas chromatography coupled with mass spectrometry (GC-MS) analyses. The four EOs incorporated in protein baits were tested for ingestion toxicity on B. oleae adults, mimicking lure and kill assays. Results showed con…
Invasive Alien Plants in Sub-Saharan Africa: A Review and Synthesis of Their Insecticidal Activities
2021
Despite the cornucopia of agricultural, economic and ecological ramifications of invasive alien plant species (IAPs) in sub-Saharan Africa, studies on their potential use as bio-insecticides have not received adequate attention compared to the burgeoning plethora of literature on their use in ethnomedicine. In the current study, we review the existing, but scattered literature on the insecticidal activity of different parts of some IAPs; specifically those invasive in sub-Saharan Africa but with published literature from Africa and elsewhere. From our literature survey, we found that 69 studies from four continents (Africa, Asia, North America and South America) reported the insecticidal ac…
