The Bohart Museum of Entomology is hosting its annual "Parasitoid Palooza" from 1 to 4 p.m., Saturday, Oct.19.
The event, free and family friendly, takes place in Room 1125 of the Academic Surge Building on Crocker Lane, UC Davis campus.
"An insect parasitoid is a species whose immatures live off of an insect host, often eating it from the inside out," said Tabatha Yang, education and outreach coordinator of the Bohart Museum. "It is part of their life cycle and the host generally dies."
Senior museum scientist Steve Heydon, who researches Pteromalids or jewel wasps, will present his work and answer questions. Graduate student Socrates Letana will also field parasite questions from the crowd.
There are some 3,450 described species of Pteromalids, found throughout the world and in virtually all habitats. Many are important as biological control agents.
Also planned at the open house:
- A family craft activity, to be announced
- Sampling of Chirp Chips, from the Bohart Museum's recent entomophagy open house
- Display of orange and black Harlequin beetles (just in time for Halloween) from Jasmin Ramirez Bonilla of the Ian Grettenberger lab, UC Davis Department of Entomology and Nematology
- Display of pumpkin-eating pests--cucumber beetles--which can be a pest on squashes, cucumbers and other members of the cucurbits family.
The Bohart Museum, directed by Lynn Kimsey, professor of entomology at UC Davis, houses a global collection of nearly eight million specimens. It is also the home of the seventh largest insect collection in North America, and the California Insect Survey, a storehouse of the insect biodiversity.
Special attractions include a “live” petting zoo, featuring Madagascar hissing cockroaches, walking sticks, praying mantids and tarantulas. Visitors are invited to hold some of the insects and photograph them. The museum's gift shop, open year around, includes T-shirts, sweatshirts, books, jewelry, posters, insect-collecting equipment and insect-themed candy.
The Bohart Museum holds special open houses throughout the academic year. Its regular hours are from 9 a.m. to noon and 1 to 5 p.m. Mondays through Thursdays. The museum is closed to the public on Fridays, Saturdays and Sundays and on major holidays. Admission is free.

"Parasitoid Palooza! will set the theme for the Bohart Museum of Entomology open house on Sunday, Jan. 11.
The family-friendly event, free and open to the public, takes place from 1 to 4 p.m. in Room 1124 of the Academic Surge Building on Crocker Lane, UC Davis campus.
"Most everyone knows that mantids eat other insects or that ladybird beetles (lady bugs) consume lots of aphids, but there is another way insects eat other insects," commented Tabatha Yang, education and outreach coordinator.
"An insect parasitoid is a species whose immatures live off of one insect host, usually eating it from the inside out," she said. "It is part of their life cycle and the host dies. This sounds like a weird way to make a living, but there are more species of parasitoids than there are insects with any other single kind of life history. The movie Alien with Sigourney Weaver co-opts this phenomenon, but in reality there are no parasitoids on humans or other vertebrates."
The Bohart open house will spotlight this unusual life cycle. Wasps, flies and beetles are parasitoids to many different insect groups.
Senior museum scientist Steve Heydon, the Bohart collections manager, is a world authority on Pteromalids, or jewel wasps, a group of tiny parasitoids. He will be on hand to talk about them.
Another group of parasitoids that will be highlighted will be the Strepsiptera, or Twisted-Wing Parasites, an order of insects that the late UC Davis entomologist Richard M. Bohart (1913-2007), for whom the museum is named, researched for his doctorate in 1938. An entire family of Strepsiptera, the Bohartillidae, is named in honor of Professor Bohart.
Live parasitoids from the lab of Michael Parrella, professor and chair of the UC Davis Department of Entomolology and Nematology will be showcased. They include Encarsa, Eretmocerus, Diglyphus and Aphidius.
"Parasitoid Palooza" promises to be a fun and wacky celebration of the diversity of life, Yang said. A family-friendly craft activity is planned as well.
Along with parasitoids, native pollinator specialist Robbin Thorp, emeritus professor of entomology, will show some live male and female "teddy bear" bees or Valley carpenter bees. Allan Jones of Davis, a noted insect photographer, delivered some to the Harry H. Laidlaw Jr. Honey Bee Research Facility from a friend's cut-down apple tree in Davis.
