TYLER, Texas – Seven students walked away winners at the Southwestern Branch of the Entomological Society meeting February 22-25 in Tyler.

Ph.D. student Derek Woller received the ESA’s Comstock Award. This prestigious award with one graduate student from each branch recognized for their accomplishments in research, service, and public engagement. The award is financial support to attend the annual meeting of the Entomological Society of America which this year is co-located with the International Congress of Entomology to be held in September in Orlando, FL.

Woller is a Ph.D student currently studying in Dr. Hojun Song’s lab where his research is focusing on unraveling the evolutionary history of a group composed of 24 flightless, small grasshopper species that inhabit scrubby, xeric habitats in the Southeast.

Woller said that he couldn’t have done it without his advisor, Dr. Hojun Song.

“There is no higher honor for a graduate student in entomology than the Comstock award, so I was thrilled when I received the news!” Woller said. “Looking over the list of past recipients

I see many names of people I know and respect very much in the entomological community, including my advisor, Hojun Song, and I’m proud to be a part of that shared history.”

Song was very proud of Woller’s hard work and dedication to his lab and research.

“The John Henry Comstock Award is the highest honor for graduate students in entomology to receive in this country. Derek has been an exemplar graduate student since 2011. First and foremost, he is an excellent scientist with many ideas. His dissertation research, which focuses on the evolution of flightless grasshopper in Florida, is likely to be a model study for studying the evolution of male genitalia in a phylogenetic framework.”

At the poster session, Erin Maxson received second place in the Master Student category for her poster “Species composition and seasonality of the natural enemies of sugarcane aphid on susceptible and resistant sorghum” and Isaac Esquivel received second in the Ph.D. category for “Spatial relationships of plant bugs in large scale cotton operations: Do edge and ecotone matter.”

Esquivel’s co-advisor Michael Brewer was proud of his accomplishments and said that he was grateful for him being in his lab.

“Isaac brings a fresh perspective to the question of how and why spatial patterns of insect presence of activity are relevant to insects on plants in agricultural lands nested within the coastal environment of South Texas,” Brewer said. “He really brings in the science of landscape ecology to his research. I has been fun to work with Isaac, and serve as his mentor along with Bob Coulson.”

Coulson also praised Esquivel for all of his hard work and dedication with his project.

“Both Dr. Brewer and I are celebrating with Isaac in his success at the Southwestern Branch Meeting. His award was not a surprise to either of us as the story of his poster was significant and interesting and his preparation was meticulous,” he said. “Good work Isaac.”

“Erin has worked very hard on the research that led to this poster, and she worked very hard on the poster itself,” Maxson’s advisor Dr. Jim Woolley said. “Her macrophotography of insects is really superb, and in a class by itself, so we were delighted, but not at all surprised, when her poster won second place in the graduate student competition.”

In the Undergraduate Ten-Minute Paper competition, Shelby Kilpatrick received first place for her talk “An updated checklist of the bees of the Commonwealth of Dominica (Hymenoptera: Apoidea: Anthophila)”

“Shelby had a lot of fun with this project during our field and tropical biology course in Dominica in summer of 2015, and she worked long hours collecting and identifying the bees,” Woolley said. “As a result she made several interesting new discoveries that she reported in her talk.  The talk itself was very well prepared and she practiced it over and over with different audiences, so again, we were delighted but not at all surprised when she won first prize in the undergraduate competition.”

Masters student Pierre Lau placed second in the Masters talks for his presentation “Analysis of pollen collected by honey bees (Apis mellifera) in developed areas”.

In the Ph.D. Student Ten-Minute Paper competition, Woller received first place for his talk “Exploring the sexy frontiers of functional morphology…in 3D!!! (Orthoptera: Acrididae: Melanoplus rotundipennis)” while Mackenzie Kjeldgaard received second for “Quantifying the diet of the red imported fire ant (Solenopsis

invicta): A next-generation sequencing approach to molecular gut content analysis,” and Adrian Fisher received third place for “The synergistic effects of almond protection fungicides on honey bee (Apis mellifera) forager survival.”

Song was very proud of Woller’s communication skills and praised his dedication to his achievements and dedication to teaching entomology.

“Derek is also a fantastic scientific communicator and his passion for outreach is unparalleled. He is dedicated to his teaching, which he takes very seriously, and the students that he interacts with always benefit and learn from him tremendously,” Song said.

“I am very proud of Derek’s achievements so far, including the recent award at the Southwestern Branch meeting, and I feel extremely lucky to have him as my graduate student. I am confident that Derek will be the next rising star in entomology.”

Eubanks was very proud of Kjeldgaard on receiving high marks on her talk.

“MacKenzie is an outstanding young scientist and an incredibly energetic student. This study utilizes the very latest molecular techniques to provide unique insight into the ecology of one of the most serious pests of Texas,” he said.

Rangel was very proud of her students and said their hard work and dedication in the past months had paid off during the meeting.

“I am incredibly proud of Pierre and Adrian because they worked really hard on their presentations,” In my lab we take time to practice every person’s talk at least twice before every meeting,” Rangel said. “Having practiced even the day before the competition one last time helped them to improve their talk and the way in which they presented their research to the audience. These and all the other awards that my students received make me not only proud but encouraged about continuing to excel in honeybee research.”

Woller also won Best Overall Photo for his photo named “Captivating Chrysalis” and Xanthe Shirley received first place in the Microphotography category for her photo called “Contemplating Quantum Physics”.

Photo salon committee chair Carl Hjelmen said that there were a total of 51 submissions in this year’s salon and said the images increased in quality compared to last year’s.

“I was very pleased with the number of submissions, especially that there were representatives from all around the branch,” Hjelmen said. “I hope the trend of increased photo salon entries continue.”

TYLER, Texas–The Department of Entomology’s graduates and undergraduate Linnaean Teams came out big during the annual Linnaean Games quiz bowl competition at the Southwestern Branch of the Entomological Society meeting during the last week of February.

The Graduate Linnaean Team received first place after defeating the Texas A&M undergraduate team in the final round of play. Both teams also competed other teams, graduate and undergraduate, from Oklahoma State University.

The graduate team consisted of Pierre Lau, Freddy Ibanez, Adrian Fisher, and Carl Hjelmen while the undergraduate team included Shelby Kilpatrick, Andrew Graf, Dayvion Adams and Bret Nash.

According to the Entomological Society of America website, the Linnaean Games are a lively question-and-answer, quiz bowl style competition on entomological facts played between university-sponsored student teams. Each team is comprised of four members and members score points for the team by answering questions correctly.

The two teams will advance to the national ESA Linnaean Games competition, as well as participate in the International Congress of Entomology meeting’s competition that will be held in Orlando in November.

“I was very excited to be participating in this year’s games, especially because we finally got first place at the meeting,” Hjelmen said. “Oklahoma historically has been a very difficult opponent and in previous years we have only achieved second. These games were especially exciting because the TAMU undergrad team was also able to beat both Oklahoma teams in order to get to second place.”

Hjelmen said that with the graduate team taking first place and the undergraduate team taking second helped them to get both undergraduate and graduate representation when they go to Orlando later this year. He also attributed the hard work to his teammates and Rangel for her great coaching.

“Needless to say, both teams have barely been able to contain their excitement for these games. This couldn’t have been achieved without all of the countless hours spent by the teams and our coach, Juliana Rangel, in practices and studying outside of the practices and games,” he said.  “All of this studying allowed us to easily answer the tricky historical entomology questions, sometimes with my personal favorite answer “C.V. Riley.”  There were really way too many difficult questions to count and it is always surprising when people know the answers!”

Undergraduate team member Shelby Kilpatrick was looking forward to going to Orlando for the national ESA Linnaean Games, as well as the International Congress of Entomology’s Linnaean Games. The national ESA meeting will be held in conjunction with the ICE meeting in Orlando, Florida.

“I am very excited about the opportunity to participate in the National Linnaean Games at the Entomological Society of America,” she said. “It will be my first time to attend a national ESA meeting and this is a historic year since it’s being held in conjunction with the International Congress of Entomology. I am very proud of my team and looking forward to the national contest in September.”

She said the hardest questions were the ones about toxicology while the easiest were the questions that included photos or about taxonomy and insect classification.

“One of my favorite things about entomology is that there will always be something new to learn,” she said.

This was Lau’s first time to participate in the Linnaean Games this year since he was an alternate during last year’s competition. He said that being an alternate helped him to know what to expect during this year’s competition.

“I thought the games this year were much better than the last because we won first and second place,” Lau said. “It has been a while since the graduate team won first at the meeting.”

Linnaean Team coach Juliana Rangel was very proud of both teams and was impressed by the amount of hard work and dedication they had put in before and during the competition.

I am extremely proud of the performance of both teams, dedication during practice rounds and their homework really had paid off,” Rangel said.

She was extremely proud of the undergraduate team because of their dedication and the depth of entomological knowledge, and their courageousness during the hardest parts of the games.

“I am extremely proud of the undergraduate. They were courageous enough to beat the graduate team from Oklahoma State University, despite the nervousness you usually get facing other teams in a competition.”

“Overall, I’m extremely proud of both teams and I’m also proud to be their coach,” she added.

COLLEGE STATION — Congratulations to Cesar Valencia and Joe Schaffner in receiving the Department of Entomology’s top awards for the year during the February faculty meeting on February 11.

Valencia received the Department’s Staff Meritorious Service Award while Schaffner was given the Lifetime Achievement award during the meeting.

Valencia is a lab and field manager for Dr. Greg Sword’s lab and also serves as the proctor of the Entomological Research Laboratory, which houses various labs and offices for the Department.

He is responsible for several tasks in the lab, including various administrative functions, such as purchasing, procurement and obtaining USDA permits, and logistical, as well as personnel supervision and general research.

Valencia was also an Extension Assistant for the Department of Entomology in College Station for 5 years. As an Extension Assistant under Dr. Carlos Bogran, he was in charge of the statewide bark and longhorn beetle survey attacking trees in Texas. He also conducted various assays on greenhouse insecticides and testing new molecules against major pests that attack ornamental plants.

In the nomination letter, Sword praised Valencia for his help in growing the lab.

“The lab facility was completely empty and I had never conducted a cotton (or any other crop) field trial in my life,” Sword said. “Since starting, the lab has hosted over 35 postdocs, graduate students, undergrads and visiting scholars, obtained nearly $2.2 million in extramural funding, and been issued a U.S. patent. Cesar played critical roles in enabling all of these accomplishments by virtue of his organizational abilities and previous experience, particularly with agriculture in the field.”

“Cesar has been the glue that holds the lab together and keeps it running on a daily basis,” Sword said. “He never shuns the opportunity to take on new responsibilities, and equally if not important he constantly seeks new opportunities for additional training or projects to initiate in the lab.”

The Department also recognized Joe Schaffner with the Lifetime Achievement Award

Schaffner was hired as an Assistant Professor in our department in 1963. For several years he had responsibility for deciduous fruit tree entomology in Texas. He then moved through the ranks to become Professor, and retired and was awarded a Professor Emeritus in 1997. During this time he researched the systematics and taxonomy of true bugs, focusing on the Miridae, or plant bugs.

During his career, Schaffner also served for approximately 17 years as the Graduate Advisor for our department where he tirelessly worked to identify and recruit top prospects for our graduate program, and he stayed with them through the application process and their subsequent careers.

Students, particularly international students, remembered Schaffner as someone who was always willing to help them with anything that came up, and as someone that they could trust and always turn to for advice

Schaffner’s greatest contribution to the Department, and to the field of entomology, has been a lifetime of work in collecting, preparing, and curating a huge number of specimens of extremely high quality into the Texas A&M Insect Collection.

He was also well known for his extended collecting trips to Mexico, on which he took many students and colleagues, often providing students with their first experiences in international field work. Joe’s work in the Insect Collection has continued to the present (quite literally).

In addition, the Department recognized two faculty members for service, including Dr. Robert Coulson for 45 years with the Department, and Dr. John Oswald for 20 years.

The Department of Entomology would like to congratulate Ph.D. student James Glover for receiving the Best Ph.D. oral presentation prize in the Insect Management category at the Cotton Beltwide Conferences in New Orleans on January 5-7.

Glover received the award for his talk titled, “Comparing Boll Injury and EILs for Species of a Boll-Feeding Sucking Bug Complex (Hemiptera: Miridae and Pentatomidae) on South Texas Cotton.” Texas A&M AgriLife Research professor and co-mentor Dr. Mike Brewer said that Glover’s research is on the injury of cotton plants from a species complex of boll-feeding sucking bugs represented by one species of plant bugs and two species of stink bugs.

During his research, field collected stink bugs and verde plant bugs were used to infest cotton plants that were maintained free of insect injury. The plants were caged in different insect densities, including 0 for the control, 1 bug per cage, 4 bugs per cage and 8 bugs per cage. Each treatment was replicated 12 times across two bloom specific periods mid and late bloom.

Glover said that the bugs remained caged on the plants for 7 days then were terminated. After the infestation period, the plants or bolls were allowed to mature inside the cages. The response from the bolls, he said, included external and internal boll damage in the form of warts, galls, lint deterioration, and boll rot. The bolls were rated at harvest on a 0 to 4 scale, which corresponded to the number of damaged locules and the boll rot was scored by the visual presence or absence of diseased locules.

He said that significant boll injury differences were detected across species and yield and that insect density relationships were used to calculate and compare economic injury levels.

Brewer said that his research also included the assessment of economic damage and collaborative work with Gino Medrano of the USDA-ARS, about the insects’ transmission of cotton boll rot.

“James did a great job balancing the components of what makes for a solid field crops entomologist: he knew his cotton, he knew his science, and agricultural relevance to the topic,” Brewer said. “His work has direct implications in improving management of this pest complex in cotton grown along the Texas Gulf Coast, and contributes to understanding why ‘outbreaks of damage’ occur.”

Glover’s co-mentor Dr. Greg Sword also was proud of him and that he was the fourth person out of his lab to receive an award from the conference in the past four years.

“James is very thorough as a student, and that is reflected in the research his conducting. The work he presented at the Beltwide Conference to win this award was a well-designed field project that provides valuable information to help manage key sucking insects pests in Texas cotton.”
