background: fascioliasis is a zoonotic disease caused by the liver fluke fasciola hepatica . drug resistance, high costs of treatment and economic losses in meat production have emerged the need of alternative control measures into consideration. the aim of this study was to evaluate the in vitro ovicidal activity of paecilomyces lilacinus fungus on f. hepatica eggs. methods: p. lilacinus isola...

Hydrogenated cardanol derivatives were evaluated as potentially active insecticides/repellent agents against insect pests such Liriomyza sativae (Diptera: Agromyzidae) and Bemisia tabaci biotype B (Hemiptera: Aleyrodidae). Benzoylation, acetylation, methylation made on the hydrogenated aromatic ring to synthesize ingredients with potential insecticide action. Nuclear magnetic resonance spectra ...

Haemonchosis is a serious parasitic disease which generates significant economic deficits worldwide. Alternative therapies based on herbal products have shown promising results. On this basis, Aloe vera Lynn extract stands out and was the aim to evaluate its anthelmintic potential Haemonchus contortus free life-cycle stages by in vitro assays. Results evidenced presence of alkaloids, catechins,...

The in vitro effect of four isolates of the nematophagous fungi Duddingtonia flagrans (AC001), Monacrosporium thaumasium (NF34a) and Pochonia chlamydosporia (VC1 and VC4) on the eggs of Trichuris vulpis was evaluated. One thousand eggs of T. vulpis were plated on Petri dishes with 2% water-agar with the fungal isolates grown and without fungus as control. After 7, 14 and 21 days 100 eggs were r...

CONTEXT The failure of modern anthelmintics to control nematode parasites of sheep and goats is a reality on many farms in the tropical/subtropical regions of the world. This necessitates chemotherapeutic control alternatives and plant secondary metabolite with activity is one of those potential solutions. OBJECTIVE This study was design to evaluate the efficacy of solvent: solvent fractions ...

The two-spotted spider mite, Tetranychus urticae, causes damage to crops grown in northeast Brazil. adoption of biological control methods and curative (plant-based insecticides) is an essential practice for pest management agroecological systems. Therefore, the aim present study was investigate chemical properties, toxicity, ovicidal activity oils (EOs) from Lippia sidoides, Croton rhamnifolio...
