Entomology - plant pests and garden wildlife  

Red lily beetle

The Entomology Section is part of the RHS Plant Health Team, and specialises in the fauna found in gardens. The RHS has employed full-time specialist entomological researchers and advisors since 1918, providing advice to RHS members, staff and the public. Currently the section consists of two entomologists, a research assistant and a volunteer.


The Entomology Section provides advice on all animal related matters, not just insects and it is not restricted to plant pests; many enquiries concern how to encourage wildlife. This advice is given directly to RHS members and staff, and to the wider public via the RHS website and other publications. The Entomologists provide advice in person at the Chelsea and Hampton Court flower shows and respond to requests from the media and fellow scientists.


The focus of the Entomology sections research is biodiversity (wildlife) in gardens and the biology of plant pests. This research enables RHS entomologists to provide accurate and up-to-date advice on pests and wildlife in UK gardens. Results from research are published in scientific journals and interpretation provided in garden magazines and via the RHS website

Plant pest & garden wildlife publications

Plant pest & garden wildlife publications

Articles on pests and garden wildlife are regularly produced for The Garden magazine, the gardening advice pages and the Wild About Gardens website.

Research work is published in peer-reviewed journals, as are records of pests new to Britain, which are sometimes first detected as a result of enquiries sent to the RHS Members’ Advisory Service. Suspected first records are always reported to The Food and Environment Research Agency (Fera).
