Parasitoids of the Brown Marmorated Stink Bug Workshop

Brown marmorated stink bug
Trissolcus japonicus

A specialized training workshop at the University of Florida, Gainesville, FL 32608

January 31 and February 1, 2019

Note: The workshop will continue to occur as originally scheduled. It is not affected by the government shutdown.



1) Identification of pentatomoid egg parasitoids

The focus of this workshop will be identification of egg parasitoids in the family Scelionidae, and tools for identification of parasitoids in Chalcidoidea will also be available. Within Scelionidae, Trissolcus has been a genus of interest for biological control of BMSB, particularly since the adventive appearance of Trissolcus japonicus in the United States and Europe. Participants will learn how to identify the genus Trissolcus and how to separate Trissolcus japonicus from other species of Trissolcus in the United States, Europe and Asia, depending on relevance to the participants’ research agendas.

2) Techniques for preserving, mounting, and examining specimens

Proper examination and preservation is essential for correct identification and to maximize the usefulness of specimens and their associated data. Lighting, specimen mounting and manipulation, and best practices for recording data will be discussed.


The most convenient accommodation is the UF Hilton Hotel located within walking distance of the UF Entomology Building where the workshop will take place. A rate of $109/night has been negotiated which is compliant with government rates, and rooms must be booked by January 2. Other hotels are listed below, but will require transportation, and in most cases are more expensive.

Specimens: Please bring your specimens for identification. We have a limited number of specimens, and also would like to provide training on specimens that may be collected by methods specific to your research project. Please bring a small specimen box to take home a small reference collection as needed.

Morphology: We encourage participants to examine the two following publications prior to the workshop to have a basic idea of important characters and terminology. Morphological structures are thoroughly illustrated in Figures 3–6 of Revision of Palearctic Trissolcus ( The Key to Nearctic Trissolcus ( will be used for the Nearctic fauna, and the keys in the Revision of Palearctic Trissolcus will be used for the Asian and European faunas.

Equipment: Participants are strongly encouraged to purchase a specimen manipulator and bring it to the workshop. Elijah recommends the manipulator made by Rose Entomology, which is the highest quality version known to him. This item is not cheap, but it will last for decades and will greatly facilitate specimen examination. It is difficult to over emphasize the utility of this item.

A significantly cheaper model can be purchased from BioQuip, but I recommend it only if the Rose Entomology model is not a possibility.

Who should attend?

Entomologists, extension specialists, and graduate students working on brown marmorated stink bug biological control or biology of Trissolcus. Some prior knowledge of parasitoid taxonomy will be useful but is not required.
