- Bugscope TeamHello!
- 2:10 pm
- Bugscope TeamWe're defining presets to jump the scope quickly to interesting bits.
- 2:15 pm
- Bugscope TeamHi Josh! Bang on.
- Bugscope TeamYeah Dude.
- Bugscope TeamKids are often interested in the pinhole.
- 2:20 pm
- Bugscope TeamI'll do a test to make sure its working though
- 2:25 pm
- 2:30 pm
- 2:37 pm
- Bugscope Teamthat was me
- Bugscope TeamPresets are complete!
- GuestTeppie is a guest here.
- 2:43 pm
- Bugscope TeamWelcome, Teppie.
- Bugscope TeamWelcome Teppie! as a guest are you able to see private chat or just public? Will students be classified as guests when they log in.
- Bugscope TeamStudents should be in blue and guests in yellow.
- Bugscope TeamGuess you remember that.
- Bugscope TeamDifferent from all the other colors :)
- 2:48 pm
- 2:56 pm
- Bugscope TeamHi!
- Bugscope TeamHi Abby!
- Bugscope TeamHello Michele!
- StudentDr. Korb is roaming the room
- Bugscope TeamHi Erika!
- TeacherThis is Dr. Korb :) They will ask for control of the scope if you can guide them.
- Bugscope TeamHello M Team!
- Bugscope TeamHi Michele!
- Studentwhat are we looking at right now
Bugscope TeamIt's a flying spaghetti monster
Bugscope TeamI think actually it is a kind of airborne fungus -- we see it occasionally
Bugscope Teamto the left is a tarsus -- an insect 'hand'
- Bugscope Teamthere is a pollen grain on one of the FSM tendrils
- Bugscope TeamDr Korb has control. As she said, we can give anyone who asks control of the microscope.
- 3:01 pm
- Bugscope TeamM Team, Erika: are you with Dr Korb, or did you just hear about this some other way? Just curious.
- GuestHi Camille, We are all with Dr Korb
- GuestWould this fungus effect the pollinators?
Bugscope Teamnot likely. Would probably be like dirt on them
Bugscope TeamBut there are many different types of fungi and some are known to attack pollinators
- Bugscope TeamWhat is happening, worldwide, is that traditional pollinators, in the zones in which they normally live, are being forced to move to other areas
- GuestI am moving stations. I will jump back on when I get a quick break.
- Bugscope TeamDr Korb, to the left of the blue arrow are twenty other presets for you to point the scope at!
- Guestwhat kind would that be?
Bugscope TeamStonebrood and chalkbrood are examples of fungal infections that attack baby honeybees in their nests.
Bugscope TeamSounds like a couple of dwarf brothers on their way to Smaug.
- GuestCan we control the microscope please?
Bugscope TeamGo ahead!
- Bugscope TeamM Team, the Mag +/- buttons... ah, you figured it out.
- 3:06 pm
- GuestWhy would they be forced to move elsewhere? The weather? Humans?
Bugscope TeamAlso competition with introduced, non-native pollinators such as honeybees (if you werent aware, honeybees are not native to North America and were brought over by Europeans)
Bugscope Teamyes -- the weather is causing them to have to move, changes in the environment; they can move to areas where there is no food. Another thing that has happened is (e.g.) the introduction of European bees to places like Chile, where they displace (and completely replace) whole species of bumblebees
- Bugscope TeamAnd clicking in the image to recenter at that point, that's right.
- Bugscope TeamHi Michele! welcome to bugscope!
- GuestWe're leaving, but thank you so much! :)
- Bugscope TeamThank you, M team!
- GuestWhat insect is this?
Bugscope Teamit's a wasp
- TeacherDr. korb here - I am roaming the classroom helping with other sessions. Students are jumping off and on the Bugscope session as needed.
- GuestOh WOW!
- Bugscope TeamI kicked off Dr Korb! Ooops!
- Bugscope TeamSorry, I was trying to give her control of the scope. Clicked wrong thing.
- GuestIs it dead?
Bugscope TeamVery dead hopefully... the specimens need to be dead in order to be examined using an ESEM
Bugscope Teamyes all of the insects are dead, dried, and coated with gold-palladium to make them conductive
- GuestPLease give Michele control, Dr.Korb want to control it
- Bugscope TeamMichele is the supreme ruler
- Bugscope Teamthat is, Michele now has control
- 3:12 pm
- TeacherI am back...my connectivity for my laptop is sketch
- Bugscope Teamwe are hitting these specimens with 10kV of beam energy and they are under a vacuum!
Bugscope TeamSo if they werent dead, would that amount of energy kill them? Just curious
Bugscope TeamI think it's low wattage, maybe just a shock
Bugscope Teamthe vacuum might not kill them either. They could close up their spiracles (breathing holes) and wait it out
Bugscope TeamThat's what I would do!
Bugscope TeamSo hypothetically the main reason you couldnt image live specimens with the ESEM (other than ethical concerns) is that because they arent holding still the images would be blurry?
- GuestThis is amazing! Thank you.
- Studentteam buuugggggss here Dr. Korb says we can could control the microscope
- Teacherwhat is the main diet of this insect
Bugscope TeamI'm not sure which insect we are looking at right now - is this the honeybee, fly or the wasp?
Bugscope Teampresently it's the wasp
Bugscope TeamWasps usually predators or parasitoids of other insects - its difficult to tell which this one is at this magnification
- 3:18 pm
- Bugscope Teamhere is a top down view of the sample
- StudentWhat are the spikes for?
Bugscope Teamit helps stick onto things. like a burr on pet fur
Bugscope TeamBotanists also use these spikes to identify which species of plant produced the pollen. But that isnt something that the plant "cares" about.
- GuestDr. Korb says we can control the microscope
Bugscope Teamgot you!
- StudentAre the spikes why pollen irritates our eyes?
Bugscope Teamprobably in part, but there is also the possibility of an allergic reaction
- Bugscope TeamOOF
Bugscope TeamYou okay Scott?
Bugscope TeamOOF = out of focus
Bugscope TeamGotchya, I thought you might have fallen ;)
- Studentwhy are they so hairy?
Bugscope Teamthere are different types and levels of 'hairs"
Bugscope TeamInsects have an exoskeleton which makes it hard for them to sense their environment. Many of these hairs are sensory in purpose, and allow the insect to touch and smell the environment around them
- Teacherwe are going to investigate for about another 15 minutes - OK?
Bugscope TeamNo prob.
- Guestwhat are the web things?
Bugscope Teamspider webs!
- Studentwhy are bee eyes hexagons?
Bugscope Teamthat's the best shape to fit something with a curvature
Bugscope Teamlike a soccer ball
- 3:23 pm
- TeacherSOOOO great to be back on Bugscope again!!!
Bugscope TeamDr K we are totally stoked as well
Bugscope TeamI am also pretty excited about this :)
- GuestPlease take control back and show us where the leg connects to the body please :)
Bugscope Teamwe're looking for a good example...
Bugscope TeamHere you go, at last.
- StudentDr. Korb is giving Kayla microscope control now because we want to see the wasp antenna.
Bugscope Teamgot her
- Teacherif they break any limbs can they regrow?
Bugscope Teamsometimes they can grow back, but only if they have another part of a life stage to go through or a molt. Usually insects don't live long enough to molt
Bugscope TeamSpiders on the otherhand are pretty good at regrowing lost limbs if they lose them early enough in life or are long live. I had a pet tarantula named Peggy who lost a leg and regrew it in a few months when he was about half grown
Bugscope Teamis that why you named him Peggy?
Bugscope TeamYes :)
Bugscope TeamHe unfortunately was the victim of an "unsuccessful mating attempt" a few months back and is no longer with us :(
- Bugscope TeamJackie, Evellyn: you can look at a bunch of predefined parts, at the left of the screen
- Bugscope TeamClick the blue arrow to see the grid of presets to click on.
- Teacherare the hairs on the antennae to sense vibrations?
Bugscope TeamSome probably are, but most are likely serve a chemosensory function and allow the wasp to smell!
- 3:29 pm
- StudentYou can have control back.
- TeacherDr Korb here - could you give control back to korb?
Bugscope Teamgot it
- Bugscope TeamDr K do you want us to make a new sample for tomorrow?
- StudentWhat are the different parts of the mouth?
Bugscope Teamthe parts that look like insect legs coming out are called palps. they help move around and taste food
Bugscope TeamIt varies from insect to insect, but the primary mouthparts are the mandibles, labrum, labium, and maxillae. The maxillae and labium both have a pair of palps, which are used to taste
Bugscope Teamthe maxillae and mandibles are used to chew food, and the labrum and labium act sort of like lips
- Bugscope Teamjuju
- Bugscope Teamtwo tarsi
- 3:34 pm
- TeacherWhat s a flying spaghetti monster?
Bugscope TeamI think its fungus
Bugscope TeamA very special fungus...
- Bugscope Teamhere you can see the labrum Josh mentioned
- Bugscope Teamit has a pin hole
- Bugscope Teamfrom being stuck in someone's collection box
- Bugscope Teamsetae on the surface of the compound eye
- Bugscope Teamprobably mechanosensory setae that let the insect get an idea of wind speed and directions
- Bugscope Team(retest credits.html in win7 chrome: vertical layout glitch)
- 3:39 pm
- Teacherhi all - we are going to sign off. This is Michele Korb now.....we will be back tomorrow with another team of students :) YAY!!! good bye for now.
