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: 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 testing wa

The Gram-positive, spore-forming bacterium Paenibacillus larvae is the etiological agent of American Foulbrood, a highly contagious and often fatal honey bee brood disease.The species P.larvae comprises five so-called ERIC-genotypes which differ in virulence and pathogenesis rexford rut v5 strategies.In the past two decades, the identification and

The fungus Fusarium verticillioides can infect maize ears, causing Fusarium ear rot (FER) and contaminating the grain with fumonisins (FUM), which are harmful to humans and animals.Breeding for resistance ar-13995n to FER and FUM and post-harvest sorting of grain are two strategies for reducing FUM in the food system.Kernel and cob tissues have bee
