Insect Phys Final - Images And Diagrams

Front 1

Label the bars of the spider's contact with mesh and explain.

Back 1

Ground contact distributed along leg, not just foot

Front 2

Label the bars of contact with mesh and explain.

Back 2

On solid surfaces and mesh, spider does better with hairs. Roaches do better on solid without spines and worse without tarsi/with spines. On mesh they do better w/o spines but do worse without tarsi

Explain the Ashburner model below and some modifications that have been made since. Describe what technique/experiment Ashburner used to support the model.

Back 26

Puffing sequence of Drosophila polytene chromosomes initiated by moulting hormone. Model described interaction between ecdysone, its receptor, and early/late puffs during response. Ecdysone+receptor activates directly = rapid few early puffs and no late puffs. When proteins encoded by early puffs are abundant enough they repress their own promoters and activate late genes. Recent studies have IDed the different genes.

Front 27

Describe

Back 27

Parasitoids release JH and prevent JH degredation so host doesn't metamorphasize, PTTG release is stopped, PG less responsive to PTTH = decrease of ecdysone until parasitoid metamorphosis when there is a large spike

Front 28

What type of equipment did researchers use to obtain these images?

Back 28

Synchrotron

Front 29

Draw relative positions of tracheoles, taenidiae, trachea, spiracles

Back 29

Front 30

Draw diagram of mechanims of proteolytic digestion involving trypsin in mosquitoes. Explain in words. At least 1 hormone and 2 types of trypsin genes. Discuss why 2 types are needed.

Back 30

JH + blood meal activates early trypsin gene > early trypsin mRNA. Digested peptides activate transcription of late mRNA to break down peptides to aas
