BISC413 Lab 3, Sept. 3: Collecting


Look at your worms. You should have a lot; let me know if it looks like something's wrong. Replace the lid and leave a small gap for air to get in.


Today, you'll go collecting some of the organisms for the allozyme project. I'll provide containers; put tape on the containers and label them with your name, the date, and the location. Put the organisms in the containers and bring them back to the lab when you're done, and I'll put them in a -80° freezer until it's time to run allozyme gels on them.

Cullen, Emily, Greg and Lisa will drive around looking for fall webworms. I've seen them on Route 273 out past Christiana Towers and some along White Clay Creek. The goal will be to get 50 from each of six areas: maybe Route 273, White Clay Creek, Paper Mill Road, and then three similar roads south of Newark?

There are a few small patches of mile-a-minute weeds along White Clay Creek and bordering the fields in the upper part of White Clay Creek State Park (the part on Route 273). There's a very healthy clump of the weeds on the north side of Little Egypt Road, just south of Westover Road; I don't know if it has weevils in it. Once you've seen one patch of the weeds, it should be easy to recognize others; drive around and look for other patches (while you're looking for fall webworms, too).

I think this team should be able to sample fall webworms from more than one location this afternoon (although not all six). I don't know how easy it will be to sample the weevils, but hopefully you can find at least one patch of weed with a bunch of weevils in it.

Pat, Laura, Wendi and Christinewill walk up to the woods along North College Avenue and look for bess beetles. I'll provide screwdrivers for prying apart rotten wood, garden gloves, and containers. I have no idea how hard it will be to collect 50 bess beetles; if it turns out to be easy, this team should walk to another patch of woods and collect a second sample. This team should also keep an eye out for walnut trees, although I suspect it will be too early to find the walnut husk flies.

Ramya, Matt, Nate, and Zara will start by making and hanging yellowjacket traps. The traps should be clearly labelled with Matt's name and contact information, and placed where they're hidden from casual passersby; maybe a couple of traps near McKinly and a couple up on North College near the woods.

After hanging the yellowjacket traps, the team should walk up North College and collect Oniscus asellus and Armadillidium nasatum under logs and rocks next to the road.

Anna, Brianna, Fanta and Sam will make amphipod traps and put them in White Clay Creek and Paper Mill Pond. They will also look for Armadillidium vulgare. They should look for flowers with lots of honeybees and record the location, although unfortunately all of my sources of insect nets fell through so they won't be able to collect them today. I'll have some nets for next time.
