The effect of access to buckwheat flowers (Fagopyrum esculentum Moench; Polygonales: Polygonaceae) or vetch extrafloral nectaries (Vicia sativa L. cv. ‘cahaba white’; Fabales: Fabaceae) on the fitness of Anagyrus pseudococci (Girault) (Hymenotpera: Encyrtidae) (a parasitoid of the vine mealybug, Planococcus ficus [Signoret]) (Hemiptera: Pseudococcidae) was determined in the laboratory. Female A...

In this study we investigated the effect of maturity stage on chemical composition, in vitro dry matter digestibility (IVD) and volume of gas produced at 24 h (G24) of forages from Avena sativa L. (oats), Trifolium alexandrinum (berseem), Vicia sativa L. (vetch), Avena sativa-Vicia sativa (OV) and Avena sativaTrifolium alexandrinum (OB) mixtures collected at progressive morphological stages (S1...

Associated grass-legume pastures have advantages over grass monoculture; in order to evaluate them the association of black oat (Avena strigosa Schreb) with winter vetch (Vicia villosa Roth) was analysed. The objective study forage yield, botanical, morphological, and chemical composition monoculture vetch, at different crop heights residual stubble heights. Eighteen treatments were evaluated r...
