  1. 1. October EGO Meeting Minutes– Tuesday October 5, 2004 Thank you to the Department of Entomology for providing us Pizza for lunch! Attendees: Luke Jacobus Craig Roubos Al Fournier Alisha Johnson Jody Aleong Casey Butler Philip Morton Jami Guenther Wan-Tien Tsai Hong-Mei Li Shujuan Li Kate Girsch Margaret Schwinghammer Matt Tarver Soledad Rodas Overview • Future courses in Entomology • Committee Updates and Reports o Seminar Series o OVEA o Grad Symposium o Seminar Series o IT o Student Affairs o Advisory o Teaching & Curriculum • Upcoming Events o IPM in Schools Online o Grad Student Workshops o Insectaganza o Social Events • Additional Information o Handouts regarding new courses in entomology GUEST SPEAKERS: Future Courses in Entomology Dr. Virginia Ferris and Dr. Jeff Stuart Dr. Ferris discussed the new course ENTM 692X, “Insect Molecular Genetics, Phylogeny and Evolution”. This is a course that explores discussion of up-to-date journal articles. It is a 2 credit, 2 hour a week course, with no lab portion that will be offered spring semester 2005. There is a handout that outlines in detail the course taught by both Dr. Ferris and Dr. Stuart who each teach 8 weeks. Dr. Larry Murdock Dr. Murdock and Dr. Edwards introduce a new course ENTM 595A, “Case Studies in International Pest Management: Nuts, Bolts and Bailing Wire”. This course uses the real life
  2. 2. experiences of faculty members who will share stories of their international travels, research, trials and tribulations of being in a foreign land. It is a 1 credit, 2 hour a week class (1st hr - presentation, 2nd hr discussion), that will be offered spring semester 2005. Evaluation is based mainly on student participation. There is a handout with the synopsis of ideas for this course which will be taught by seven faculty members (Edwards, Murdock, Foster, Yaninek, O’Neil, Stuart, Lowenberg-DeBoer). Dr. Hunt emailed the grad students regarding a new course course entitled "Genes and Behavior" (ENTM 692G, or something like that). It will probably be Mondays from 12:30 to 1:20. Since this is the first time it will be offered, it will just be a one-credit class. However, I think that participants will get a lot out of it because it is a complex area. It is also pretty controversial because we will be talking about such topics as nature versus nurture in regards to IQ, drug addiction, schizophrenia, sexual orientation etc. However, there will be a heavy emphasis on insects and especially honey bees. Please look below minutes for additional information about new courses for spring from the professors. GRAD STUDENT AGENDA: Committee Updates and Reports Survival Skills Seminar Mike Meyers said that the program is slowly materializing. The next topic is about post doctorate positions. If there are any questions, comments, or ideas please contact Mike. Ohio Valley Entomology Association (OVEA) Al Fournier reports that there are eight Purdue students presenting at the meeting October 29 in Hanover, IN. Al Fournier will email grad students the information regarding a possible practice. Graduate Student Symposium Craig Roubos has the entomology grad student symposium ready to go for November 4 and 11. Four students will present during session 1 (Nov.4): Shujuan Li, Omprakash, Mitapalli, Wan- Tien Tsai, and Justin Vitullo. Three students will present during session 2 (Nov.11): Rajat Aggarwal, Venu Margam (new PhD student in the department), and Kris Wyckhuys. Casey Butler and Kris Wyckhuys will also be presenting posters at session 2. In addition to written feedback which the audience can provide, the option for videotaping the presentations is being explored. Department Seminar Series Schedule can be found at http://www.entm.purdue.edu/Entomology/news/seminar.html. Note there is a change on October 28. Dr. Charles Whitfield from the University of Illinois UC will be here to present “Hereditary and environmental influences on gene expression in the brain and division of labor in honey bees”. Information Technology (IT) committee Al Fournier said there is a meeting will take place October 13. Stay tuned for updates in Novemeber.
  3. 3. Student Affairs Casey Butler said the graduate student board is discussing the issue of International Students and parking The issue of parking was then discussed among the entomology grad students. Student vehicles are not allowed on campus and in loading zones, even though grad students are doing most of the loading in this building. There were discussions regarding C parking and future of phasing out of vehicles on campus all together. Advisory Committe Margaret Schwinghammer said the meeting is October 12. Stay tuned for updates in Novemeber. Teaching and Curriculum Committee Luke Jacobus reported changes in required credits in Life Science for undergraduate. Scientific illustration has changed numbers from a 500 level course to a 300 level class. Graduate student enrollment might be an issue. The question was posed: Would the number of course (300 level) discourage you from taking it as a graduate student? UPCOMING EVENTS Integrated Pest Management in Schools: On-line training course Photos are still missing for the website that will be put together by Tim Gibb, Fred Whitford and Al Fournier together with Ag Communcation. Requests for the following photos: 1) Contaminated food, 2) Animals fighting over food, 3) Field work such as scouting out in agricultural fields. If you have any of these photos please contact Al. PGSG – Academic and Professional Committee Hong-Mei is on the committee that cooperates with the graduate school to bring us seminars and workshops to improve our skills as grad students. Check http://web.ics.purdue.edu/~pgsg/ for upcoming schedule of events. This Thursday there is workshop called The Robert Lowman Proposal Writing Workshop/ The Twelve Keys to Success in Grant Writing”. Jody will be in attendance if you need information or notes.

  7. 7. Case Studies in International Entomology: Nuts, Bolts, and Bailing Wire DRAFT ENTM 595A Organizers -- C. Richard Edwards and Larry Murdock Course goals: (i) To give graduate students an opportunity to learn about the trials, tribulations, joys and professional rewards of research in international pest management; (ii) To help students to think innovatively and creatively about specific international pest management challenges that have been researched by Purdue faculty; (iii) To share the experiences and lessons learned by participating faculty – and thereby to get better acquainted with those faculty and profit from their experience. Approach Seven faculty will present their research experiences in international pest management and lead subsequent discussions. Two class hours will be given to each topic. There will be a total of seven topics. During the first hour for each topic the presenter/discussion leader will introduce the subject matter. He will define the international pest management issue, provide historical background, socio-economic information, tell about the importance and role of the crop, provide a political perspective on the country or region, talk about partners such as Non-Governmental Organizations (NGO’s) and National Agricultural Research Programs (NARS) as well as International Agricultural Research Centers (IARC’s) and share other appropriate information with the students. The students will be challenged to develop their own ideas about how to address the problem at hand. During the second hour there will be an interactive, active discussion covering how the students might have approached the problem as well as how the discussion leader actually approached it. Lessons learned will be discussed. The students will develop a Scope of Work, including projected budgets for an proposed international pest management project. Length is expected to be several pages. Readings may be assigned by individual presenters. Attendance and Grades Class attendance and participation are essential. Grades will depend upon class participation and evaluation of the written Scope of Work prepared by the students. International Pest Management Topics Specific topic titles have not yet been developed. Areas to be explored include: C.R. Edwards – on management of corn rootworm in eastern Europe; L.L. Murdock – technologies for post- harvest storage of cowpea grain in West Africa; Rick Foster – IPM of vegetable pests in Mali. Additional faculty participants are: Prof’s. Steve Yaninek, Bob O’Neil, Jeff Stuart, and Jess Lowenberg-DeBoer (Ag Economics).
  8. 8. Genes and Behavior Class: 1 credit Overview. This class will be an introduction to genes and signaling pathways that influence behavior, primarily by taking examples from current literature. Since the scope of the class is broad, it will be considered as a brief introduction to this area of study. Topics will range from classical behavioral ecology of insects to examples from human diseases. Examples from mice, C. elegans and Drosophila will be used, but many examples will come from social insects and especially the honey bee. Particular topics will include genetic assumptions in behavioral ecology, group selection and social behaviors in honey bees, microarray studies, intra-genomic conflict and imprinting, neural signaling components and mapping behavioral genes as quantitative trait loci. The organization of the course will be as a journal club. Papers will be provided each week as PDFs. Students will take turns leading discussions. Topics: What is behavior? Are there genes for behavior? Discussion of behavioral ecology and the adaptationist approach. Intro to QTL mapping. The “social gene” of C. elegans. Drosophila behavioral genetics. Signaling pathways, molecules and behavior. Discussion of neurotransmitters, neuromodulators, second messengers and receptors. QTL mapping in mammals. Role of Inheritance in Behavior Eugenics Revisited. The Genetic Basis of Complex Human Behaviors. The Maddening Hunt for Madness Genes QTL studies for reading disability and sexual orientation. Genetic markers for schizophrenia. The genetics of drug addiction in people, rats and flies. Behavioral genetics of honey bees. How haplodiploidy influences evolution of social behavior and polyandry. Division of labor. Foraging choices that are under genetic constraints. The “foraging gene” in flies and bees. Aggressive/defensive behavior of bees. Genetics of the rate of behavioral development in bees – microarray and QTL data. Learning in flies and bees: Genes identified in flies, QTLs in bees, motivational states. Imprinting and behavioral traits. The kinship theory of genomic imprinting and how haplodiploidy influences imprinting. Complexity and phenotypic plasticity of behavior.
