The importance of co - authorship and disciplined research

This study reviewed articles in a Pacific Islands Educational Journal from 1978 to 2005 in order to analyse the types of authorship and types of papers published. It was specifically interested in looking at the prevalence of co-authorship and in identifying the style of authorship and the research approaches taken. It was found that of the 362 authors, most of them are single authors at 75.7 and 24.3% were involved in co-authorship. In terms of the types of papers, 72.7% wrote essay or opinion papers, 17.7% wrote articles based on quantitative approaches, 7.7% wrote qualitative articles and 2.2% wrote articles using mixed method approaches. These findings have important implications for research and publication in higher education and research in and on the Pacific Islands, in terms of encouraging collaborative research among researchers and being out in the field to collect data to enable better evidence for education

Biological control of cacao diseases

This chapter discusses the advances in biological control of cacao diseases over the last 15 years. Most attention has been focused on biological control of frosty pod rot (Moniliophthora roreri), witches' broom (Moniliophthora perniciosa) and black pod disease (Phytophthora spp.). Research on biocontrol of other diseases in the cacao phyllosphere or rhizosphere is scarce or in its infancy. There is, however, a steady increase in information regarding the factors influencing and the mechanisms underlying biological control of cacao diseases as well as practical aspects such as inoculum production, formulation and application. There has been a clear shift away from inundative approaches using epiphytic BCAs towards more classical biocontrol approaches using bacterial and fungal endophytes as well as vesicular arbuscular mycorrhiza. These have the advantage that they can permanently establish themselves in the cacao tree. Moreover, besides direct competition for space and nutrients, antibiosis and mycoparasitism, through induced resistance and growth promotion, endophytes have a larger arsenal of mechanisms through which they can help protect their host. Endophytic BCAs could thus provide more effective and sustainable disease control. Recent advances in our understanding of the mechanisms through which endophytic biocontrol agents can reduce pest and disease impact provide possibilities for innovative disease control strategies, including combination therapies together with natural or chemical products. Continued work on production, formulation and application is also necessary in order for biocontrol to become economically interesting. However, biological control will not become a stand-alone solution for disease control but should become part of integrated pest management strategies, with cultural management as a central and reinforcing pillar.
