RISK ASSESSMENT OF THE LABORATORY HOST RANGE AND A MOLECULAR CHARACTERISATION DETERMINING THE FIELD HOST RANGE OF LIXUS AEMULUS, FOR THE BIOLOGICAL CONTROL OF CHROMOLAENA ODORATA IN SOUTH AFRICA

Risk assessment of the laboratory host range and a molecular characterisation determining the field host range of Lixus aemulus, for the biological control of Chromolaena odorata in South Africa

Chromolaena odorata (Asteraceae: Skort Eupatorieae) is a sprawling shrub native to the Americas, and a destructive invader of much of the humid tropics and subtropics of the Old World.Opportunistic native-range exploration in 1995 identified a stem-boring weevil, Lixus aemulus, as a promising biological control candidate agent.Host-specificity test
