Ruth Huwer is a research entomologist at the Centre for Tropical Horticulture in Alstonville, Far North Coast NSW, where she is leading the Entomology team.
She joined NSW Agriculture* in 2002 as Entomologist and has undertaken research in pest management in subtropical/tropical horticultural crops, developing more sustainable pest management strategies with the aim to reduce the use of broad-spectrum insecticides. Her research includes advancing IPM in macadamias. Particular aspects of this research are biological control, pest – host plant interaction specifically host preferences, semiochemicals and chemical ecology, alternative host and trap crops, evaluation of new insecticides. Management of fruitspotting bug (Amblypelta spp.) a key pest, is driving the IPM strategy.
As part of a management strategy of longicorn beetles in lychees, the optimum timing of chemical application and efficacy of different chemicals are being evaluated.
Ruth Is also involved in PestWeb, an insect pest monitoring program developed by farmers from a local Landcare group. PestWeb allows tracking of the movement and the distribution of pests, facilitates communication between farmers, sharing of monitoring data and helps farmers make pest management decisions.
A previous study investigated the management of scarabid beetles in blueberries. This study included pesticide trials and utilization of different cover crops in the inter-rows.
Ruth has over 10 years scientific research experience in Australia, and has published a number of scientific papers, including peer-reviewed publications.
