Abstract

We introduce our ongoing work in the sweet potato production systems of Papua New Guinea (PNG) where cash-cropping is developing from subsistence farming. Surveys have shown that arthropods - especially weevils - are the major plant protection concern. Despite growers reporting use of a wide range of plant protection methods including biological control, a large majority use no active intervention. Our work is evaluating the potential for biological control interventions to complement traditional practices such as the use of pigs and poultry to consume pests and crop residues. Field surveys in PNG as well as in Australia are being used to explore the diversity of natural enemies, whilst laboratory and field studies are comparing candidate entomopathogens (e.g. Metarhiziumsp. and Pasteuria sp.) and investigating the influence of volatile and non-volatile plant compounds.

OtherMore than 130 biological control researchers and practitioners from 25 countries came together during the week of 11 to 15 September 2017 to participate in the global flagship conference on the biological control of arthropods using parasitoids and predators. Organised by CABI Malaysia and the Malaysian Agricultural Research and Development Institute (MARDI), the International Symposium on the Biological Control of Arthropods (ISBCA) took place in Langkawi, Malaysia. The local organising committee for the symposium comprised Dr. Loke Wai Hong and Dr. A. Sivapragasam from CABI together with Dr. Mohamad Roff from MARDI.

The conference, the fifth in a series of symposia held every four years, presented a unique forum for arthropod biological control researchers and practitioners to meet, exchange information and discuss up-to-date issues relating to biological control. This year’s event focused on the use of parasitoids and predators in the ongoing battle to control certain invasive arthropod species.
