IOBC Canada 2017 – Part III

This post is a part of a series of notes taken at the International Organization of Biological Control 2017.

Go back to Monday’s Agenda

Foraging and egg-laying behaviour of the coccinellid predator Rhyzobius lophanthae
Marjolein Kruidhof, Wageningen University & Research, BU Greenhouse Horticulture

  • Diaspis boisduvalii scales in cymbidium; major problem in Netherlands and they don’t know what to do anymore to control
    • Due to restrictions of use of chemicals (i.e. neonics), they have been unable to control the scale
  • Cage experiment; comparison of different natural enemies of Diaspis boisduvalii scales
  • Tried 8 different treatments, different release rates and frequencies of release of Rhyzobius lophanthae larvae or adults (with or without ephestia eggs)
  • In control, plant was covered with the scale at the end (5 weeks later)
    • When releasing R. lophanthae adults and ephestia eggs, got excellent control
  • R. lophanthae is a predatory beetle
    • Adults are about 2.5mm in small
    • Specialist predators of the Diaspididae family
    • Lays eggs under the shields of adult female scales

Jon Nemati – Ext. Demonstration Tech

Jonathan Nemati first joined the Six-legged Aggie team in early May of 2015 before returning to the center in April 2017. He graduated from LeTourneau University in 2016 with a B.S. in Biology.

He has had an interest in wildlife since he was little, collecting and observing a wide variety of wildlife as a hobby as well as studying to improve his knowledge of them. He also enjoys reading, hunting, hiking, fishing and a wide variety of sports. He intends to pursue graduate studies in ecology.

Jon’s role this summer will be to assist in data collection, analysis, and writing reports related to crapemyrtle bark scale, aphid, and thrips management.

Briton Grove – Ext. Demonstration Tech

Briton Grove is a graduate of University of Texas at Tyler with a BS in Biology and a minor in Biochemistry. 

She is interested in how the study of insects could help advance our understanding of antibiotics and disease. Her previous research experience including studying how CRISPRs grant acquired immunity to many viruses and how this tool could be used in autism research. She intends to start a master’s program this fall (2017) at University of Texas at Tyler, concentrating on entomology. For her master’s thesis, she will examine the roles that bacteria play in the stabilization of fungus-gardening ants and their symbiont fungi, including the use of antimicrobial compounds.

In her free time, Ms. Grove enjoys camping, traveling, and gardening. She also gives back to her local community by volunteering with Texas Mission of Mercy as a dental assistant, providing free dental care to low income residents.

Ms. Grove will be assisting Erfan Vafaie with research on the crapemyrtle bark scale, thrips, and aphid management this summer as an Extension Demonstration Technician.

IOBC Canada 2017 – Speaker Summaries

The International Organization for Biological Control (Nearctic Region and West Palearctic Regional Section) had a meeting in Niagara Falls (Ontario) from June 4th – 8th, 2017. Below is a list of the talks that I took notes for. When the notes for that talk are published, the title will become a clickable link. Since there were many talks and I need to gather my notes into coherent ideas presented by the speakers, I will be publishing notes progressively over time. Check back later if a title you are interested below is not yet posted.

Biological control in greenhouse IPM systems: Where we’ve been, where we are, and where we need to go?
by Michael Brownbridge

Greenhouse production:

  • Unique production environment
  • Many variables within the production system: crop, pest, production practices, and external environmental factors

Talk is on where Michael believes many of the challenges in biological control are (Canadian/NA perspective)
