The Interdepartmental Toxicology Graduate program believes that professional travel, whether local, national, or international, builds confidence, aids in networking, provides access to a community with similar research interests, and helps you develop the ability to communicate and defend your own research. Conferences and Symposia can recharge and open new avenues of thought. Talk with your major professor and POS committee members about the best opportunities.
Below are potential resources for funding for travel. Here is a form sample that you can use to keep track of travel expenses for reimbursement.
Request a Iowa State University Professional Advancement Grant Travel PAGs may be granted to students who attend a professional meeting, defined as a gathering of an organized society of professionals for the purpose of presenting research. Travel PAGs may also be approved for attending professional workshops that provide hands-on experiences not available at Iowa State University (ISU). Travel PAGs will not provide funding for required academic activities as defined in GPSS Bill 93-06, including workshops, classes, or other events required for fulfillment of a student's degree requirements or program of study. Travel PAGs are divided into two categories depending on the student's involvement at the meeting: Presenters and Non-Presenters (attending only). To qualify for a Presenting Travel PAG, the student must present results of research performed at ISU at the professional meeting. These categories are described in detail in GPSS Bill S07-01.
Symposia and Conferences may have travel grants for graduate students who are willing to help with the symposia or who are presenting. We recommend also checking with your home department for available travel awards.
Students who are supported by training grants maybe able to request funding from training grants resources. (Example: IGERT, USDA, MGET, NSF).

"Rapid screening for veterinary drug residues in food and companion animal tissues using liquid microjunction surface sampling probe mass spectrometry." LC/MS is frequently used to screen for veterinary drug residues and other xenobiotics in animal tissues for food safety, diagnostic, and toxicological purposes. Conventional LC/MS screening of animal tissue requires a series of time-consuming and resource-intensive sample extraction and preparation steps. The liquid microjunction surface sampling probe (LMJ-SSP) extracts analytes via a liquid microjunction with a sample surface. Extracted analytes flow through the LMJ-SSP to an electrospray ionization source where ions are created and passed to a mass spectrometer for analysis. The LMJ-SSP provides a simple, rapid, and economical option for screening of veterinary drug residues and xenobiotics in animal tissues.

ABSTRACT "Assessing risks of insecticides used in corn and soybean production on monarch butterfly (Danaus plexippus) larvae."

Over the last two decades populations of monarch butterflies in North America have declined significantly. Conservation efforts in the U.S. Midwest are focused on restoring milkweed (Asclepias species), the sole food source of monarch larvae. Restored milkweed habitat could be placed in close proximity of corn and soybean fields, where insecticides are often used for pest management. Risks of monarch larvae exposure to these insecticides at the individual habitat patch and landscape scales are unknown.
Larvae could be exposed through the cuticle by spray drift from foliar applications. Dietary exposure also could occur if monarch larvae ingest milkweed leaves with insecticide residues from spray drift deposition or systemic uptake from treated seeds. Cuticular toxicity studies were undertaken with beta-cyfluthrin, chlorantraniliprole, chlorpyrifos, imidacloprid and thiamethoxam and risk quotients (RQs) were calculated at different distances from treated fields (0, 50, 100 and 125 feet) using AgDRIFT, a spray drift model. For aerial applications, predicted percent mortality for 1st instars ranged from 100% to 44%, 100% to 7% and 100% to 1% at the edge of field, 50 feet and 100 feet away from treated fields, respectively. For 5th instars, percent mortality ranged from 100% to 0%, 97% to 0% and 82% to 0%. In general, predicted mortality rates were higher for beta-cyfluthrin and chlorantraniliprole and lower for thiamethoxam and imidacloprid. Preliminary acute dietary toxicity results for systemic insecticides are being compared with residue values reported in the literature. Cuticular and dietary neonicotinoid exposures to 5th instars caused them to die at the onset of pupation, approximately 96h after treatment. Prior to pupation larvae behaved normally. This phenomenon occurred less commonly with the other insecticides.
The estimated larval survival rates obtained from the deterministic risk assessments are being incorporated into a projection model to predict population responses at the landscape level. These analyses will inform conservation costs and benefits of establishing habitat in areas potentially exposed to insecticides.
- Edmund Norris, (Entomology/Coats) ($300)Society of Vector Ecology, Palama Mallorca, Spain. Abstract: The burden of mosquito-borne diseases to public health throughout the world cannot be underestimated. Every year, approximately 700,000 people die from complications associated with etiologic disease agents transmitted by mosquitoes. With insecticide-resistant mosquito populations becoming an ever growing concern, the need for new insecticidal formulations is more important than ever. We screened mixtures of various synthetic pyrethroids and natural pyrethrins (permethrin, deltamethrin, �-cyfluthrin, and natural pyrethrum) with various essential oils in order to enhance the efficacy of these insecticides. We have previously shown that some commercially available essential oils have the ability to enhance the mortality caused by the synthetic pyrethroid, permethrin. We have demonstrated that many plant essential oils are capable of differentially enhancing various synthetic pyrethroids. Moreover, we have also tested mixtures of plant essential oils and synthetic pyrethroids against insecticide-susceptible strains and an insecticide-resistant strain of Aedes aegypti in order to better assess the ability of these plant essential oils to enhance synthetic pyrethroids in wild mosquito populations. These plant essential oils were capable of enhancing synthetic pyrethroids in both insecticide-susceptible and insecticide-resistant mosquito strains. This percentage enhancement was most notable in insecticide-resistant strains. A second resistant strain of Anopheles gambiae was also screened. Here plant essential oils were capable of producing very high levels of enhancement of permethrin. This work demonstrates the potential of plant essential oils in future mosquito control formulations, especially those used for the control of Aedes aegypti and Anopheles gambiae, the primary vector of both Dengue fever and Zika virus.
