Biology: A Molecular Approach, Laboratory Lab 2 Today’s Plan • • • • • • Attendance Handout Introduction to Your Research Project Webquest on Mosquito Biology Mosquito Trapping Mosquito Identification Introduction to your Research Project Mosquito Heartworm nematode (Dirofilaria immitis) Bacteria (Wolbacchia pipientis) WO Phage Introduction to your Research Project • Questions – In our region: • Which mosquito species are infected with the bacteria Wolbacchia pipientis? • Which mosquitoes species are infected with the heartworm Dirofilaria immitis? • Methods – Trap mosquitoes – Identify sex and genus/species of trapped mosquitoes – Use PCR to detect presence of Wolbacchia pipientis and/or Dirofilaria immitis in identified mosquitoes Webquest on Mosquito Biology • Assignment – Goal is to help you learn about • • • • Mosquito biology and ecology The nematode Dirofilaria immitis The bacteria Wolbacchia pipientis The WO phage – You will use this information to prepare your scientific writeups on your research project – You also will be tested on this during a lecture exam Webquest on Mosquito Biology – Complete this assignment individually! – After lab, download the file “Mosquito Biology and Ecology” • Angel; JCC Biotech; BAMA: A Molecular Approach, Laboratory; Lab 2 • Follow instructions exactly as stated in the file • Type your answers directly into the file and submit your file into the Angel drop box called “Mosquito Biology and Ecology Drop Box”: – Angel; JCC Biotech; BAMA: A Molecular Approach, Laboratory; Lab 2 – Due date is Wednesday,September 12, 2:40pm Mosquito Trapping • In a couple of weeks, you will need to writeup how to trap mosquitos for your scientific writeup – Two places to obtain this information • File called “Mosquito Trapping” – Angel, JCC Biotech, BAMA: A Molecular Approach, Laboratory, Lab 2 • Jamie Haight – Take notes on his presentation today Mosquito Trapping • Jamie Haight’s Presentation • Walk to the woods to set the traps Mosquito Morphology • Two Resources – Identification Guide to the Mosquitoes of Connecticut • Is in the ring binder at your lab benches • p. 37 - 39 – File called “Mosquito Identification” • Angel, JCC Biotech, BAMA: A Molecular Approach, Laboratory, Lab 2 • Get your laptop on and logon to the Internet • Find and open this file now • p. 1 – 5 • Don’t memorize the morphology; just refer to these two resources when you come across terms as we do mosquito sexing and genus/species identification Mosquito Sexing • Do this activity in your group • Open the file called “Mosquito Identification” • Angel, JCC Biotech, BAMA: A Molecular Approach, Laboratory, Lab 2 • Read the section on “Mosquito Sexing” on p. 1 • Identify the sex of the mosquitoes in your practice tube – Use the dissecting microscope – Gently empty the tube of mosquitoes into the petri dish – Use forceps to gently manipulate and view the mosquitoes • We’ll help you use the scopes – Keep females in the petri dish – Put males back into the practice tube Mosquito Genus and Species Identification • You need to learn how to identify the genus and species of the most common local mosquitoes – Anopheles genera • Anopheles quadrimaculatus • Anopheles punctipennis • Anopheles walkeri – Culiseta genera • Culiseta melanura • Culiseta morsitans – Culex genera • Culex territans • Culex pipiens • Culex restuans – Coquillettidia genera • Coquillettidia perturbans Mosquito Genus and Species Identification • Two Resources – Identification Guide to the Mosquitoes of Connecticut • Is in the ring binder at your lab benches – File called “Mosquito Identification” • Angel, JCC Biotech, BAMA: A Molecular Approach, Laboratory, Lab 2 • Should have this file already open – Don’t memorize these resources, just learn how to use them to identify the mosquito genus and species Mosquito Genus and Species Identification • Do this activity in your group • Identify the Anopheles genera – Do step 1 on p. 40 of the Identification Guide to the Mosquitoes of Connecticut • You do not need to look at the scutellum • Identify the Anopheles species – Use the information on p. 7 of the filed called “Mosquito Sexing and Identification” Mosquito Genus and Species Identification • Do this activity in your group • Identify Coquillettidia perturbans – Do step 8 on p. 43 of the Identification Guide to the Mosquitoes of Connecticut – See also the information on p. 10 – 11 of the filed called “Mosquito Sexing and Identification” Mosquito Genus and Species Identification • Do this activity in your group • Identify the Culiseta and Culex genera – Do step 9 on p. 43 of the Identification Guide to the Mosquitoes of Connecticut Mosquito Genus and Species Identification • Do this activity in your group • Identify the Culex species • Do steps 1 and 4 on p. 57 – 58 of the Identification Guide to the Mosquitoes of Connecticut • See also the information on p. 9 of the filed called “Mosquito Sexing and Identification” Mosquito Genus and Species Identification • Do this activity in your group • Identify the Culiseta species • Do steps 1 on p. 59 of the Identification Guide to the Mosquitoes of Connecticut • See also the information on p. 8 of the filed called “Mosquito Sexing and Identification” Supplies • Mosquito trapping – CO2 tank – Dry ice machine – 6 dry ice cubes – Cooler to hold dry ice at -80C until used – 2 CO2 traps – Batteries – Battery charger – Sheets to record when set and what was collected – Mosquito Trapping File • Mosquito ID – 6 Dissecting microscopes – 6 Forceps – 6 Petri dishes – Mosquitoes sorted into 6 plastic tubes in a rack which are a mix of unknowns – 6 Printouts of Identification Guide to the Mosquitoes of Connectictut – Mosquito Sexing and Identification File • General – Laptops – Mosquito Biology and Ecology Webquest File
