Delairea odorata Lemaire (Cape ivy) (Asteraceae) has become naturalized and invasive in many countries including the United States of America where biological control is being considered as a long-term solution to managing this invasive vine. Extensive surveys throughout the natural range of D....

Cape-ivy, Delairea odorata Lamaire, is an ornamental vine, native to the eastern part of South Africa, which has escaped into natural areas in many countries and become a serious pest. Exploratory surveys in South Africa located several potential biological control agents. One of these is ...

Secusio extensa (Lepidoptera: Arctiidae) was evaluated as a potential biological control agent for Madagascar fireweed, Senecio madagascariensis (Asteraceae), which has invaded over 400000acres of rangeland in the Hawaiian Islands and is toxic to cattle and horses. The moth was introduced from...

A major step in tackling invasive alien plants consists of identifying those species that represent a future threat to managed and unmanaged habitats. The European and Mediterranean Plant Protection Organization reviews and organizes data on alien plants in order to build an early warning system. A ...

Medicinal plants have been historically used as treatment for different kinds of human diseases. In this study, hot water (HW) extract of five Taiwanese traditionally used medicinal plants (Eclipta prostrata, Blumea lacera, Ixeris chinensis, Senecio scandens and Tithonia diversifolia) was evaluated ...
