Two different types of condensed tannins (CTs), which were extracted and purified from tilia (Tilia L.) black locust (Robinia pseudoacacia), studied tested against two kinds bacteria, including Gram-negative Gram-positive, avian pathogenic E. coli (APEC) Staphylococcus epidermidis (S. epidermidis) respectively, by minimal bactericidal concentrations (MBCs) scanning electron microscopy (SEM). Bo...

Oobius Trjapitzin (Hymenoptera, Encyrtidae) species are egg parasitoids that are important for the biological control of some Buprestidae and Cerambycidae (Coleoptera). Two species, Oobiusagrili Zhang & Huang and Oobiuslongoi (Siscaro), were introduced into North America for classical biocontrol and have successfully established. Two new native North American species that parasitize eggs of Agr...
