Be BRAVE: Pear Psylla Management

On Thursday, February 18, 2021 as part of an OSU/WSU webinar, Stijn van Laer gave a talk on pear psylla management in northern European pear orchards.  Stijn is a crop consultant that works for company called FruitConsult based in Belgium.  They are a private consulting firm that does not sell products (i.e., chemicals), just management recommendations. Stijn discussed management of pear psylla in European orchards with conservation biological control (i.e., only using soft insecticides and at economic thresholds) and by augmentation of earwigs.  He also discussed the importance of proper sprayer calibration and how this can make or break effective management.

Join us for pear study circles this winter – they’re free!  It’s a great learning opportunity for growers, consultants, researchers, and industry professionals.  Our goal is to improve pear profitability and sustainability. Each study circle will include a 30 minute presentation and 2 hours of facilitated discussion.

Topics include:

  • Oct 19, 2021 – Choosing products that work: A discussion of pesticide efficacy
    2019-2021 research results from Louis Nottingham, WSU Entomology. Grower experience from the field.
  • Nov 23, 2021 – Honeydew Washing Systems – Adding a Cultural Control to your Toolbox
    2020 research results from Tianna DuPont, WSU Extension. Grower presented case studies.
  • Dec 14, 2021 – Using pear psylla phenology to better time applications
    Outline of the new psylla phenology model from Louis Nottingham, WSU Entomology. Examples of scouting information showing when the model has worked and when it has not. Brief intro to potential scouting app. Discussion of getting weather stations to improve accuracy. Discussion of how growers/consultants want to best access data.
  • Jan 11, 2022 – Assembling IPM programs that work
    Discussion of IPM and bio-based IPM programs step by step through the season and new research on natural enemy impacts of current products, Louis Nottingham, WSU Entomology.
  • Feb 8, 2022 – How can we integrate thresholds and scouting?

Psylla Sampling Instructional Video

How to Sample for Pear Psylla Using Beat Trays

Louie Nottingham demonstrates how to sample for pear psylla using the tray tap method, also known as the beat tray method.  You will need an 18″ x 18″ beat tray (DYI or available for purchase at some ag chemical companies), a tapping stick and a sampling plan for your orchard.

Dr. Angelita (Angel) Acebes-Doria interview

November 19, 2020

Nottingham Interviews Dr. Angelita (Angel) Acebes-Doria in Entomology Today.

Read my interview with an incredibly inspirational entomologist, Dr. Angel Acebes-Doria; someone I’m proud to call a colleague and friend.

Angel discussed topics that many early career scientists face, such impostor syndrome and running a research lab during COVID, but also some that are more specific to people who came to the US from other countries for their education and careers.

Huge thanks to Angel for bravely sharing her stories and perspectives on some difficult issues, and to the Entomological Society of America, Early Career Professionals Committee, and Entomology Today for the platform and opportunity.
