The “makings,” is now published. It's the first of what is expected to be many in his entomological career.
“A Checklist of Mantodea of Belize, with a Regional Key to Species,” co-authored with UC Davis professor and arachnologist Jason Bond, is now online on ZooKeys.
“Lohit did a great job on this, and there's even an online Lucid identification key,” said Bond, the UC Davis Department of Entomology and Nematology's Evert and Marion Schlinger Endowed Chair in Insect Systematics and the newly selected associate dean of the UC Davis College of Agricultural and Environmental Sciences.
“This is a great example of undergraduate research opportunities in entomology,” said Bond. Garikipati worked in the Bond laboratory as a lab assistant before and after receiving his bachelor's degree in entomology in June 2019. He is now studying for his master's degree in biology at Towson University, Md., with advisor Christopher Oufiero.
For the ZooKeys publication, Garikipati and Bond updated the list of known Mantodea in Belize, adding 12 new species to the country records, bringing the total known species of Mantodea in Belize to 21. They provided information on habitat and microhabitat observations; and a regional dichotomous key and Lucid interactive key to known species in Belize. They also included a list of other possibly endemic species. In addition, the scientists remarked on the merit of further sampling efforts in central America, based on recent studies.
“Our findings,” they wrote in their abstract, “suggest that our understanding of Central American Mantodean diversity could be vastly improved by further documentation.”
Grateful to Jason Bond. “After a probably too lengthy amount of time, I am extremely pleased to present my first publication,” Lohit wrote on his Facebook page. “I cannot understate how grateful I am to Jason Bond for providing his time and advice to help guide me through this process, it quite literally would not have been possible without his enthusiasm and support. Thanks to the other members of the Bond lab as well for their advice and critique of various parts of the manuscript during its development. Hopefully we can continue to update and document the fauna of the southern Yucatan peninsula and further our understanding of mantis distribution.”
Mantids have long fascinated Lohit, who grew up in Pleasanton, Alameda County. “I first became interested in praying mantises when I was about six years old,” he said. “I found a praying mantis on my aunt's curtain in India and had no clue what the insect was! After a lot of Googling and finding out that people kept various species as pets, I started rearing both native and exotic species.”
“Admittedly, mantises are not the easiest organism to rear; it took me a few years before I bred my first species, Mantis religiosa (Linnaeus),” Lohit said. “I was really fascinated just by their hunting methods and cryptic strategies; I think I could watch them hunt another thousand times and still be as fascinated. Currently, I think I'm pushing 40 or 50 species that I have reared, with representatives from most families. Captive observations have been a large part of fueling my interest and raising questions about these organisms, as they've afforded me the chance to watch organisms that are often rarely found in the wild.”
High Biodiversity. The June 22-July 6 bioblitz, led by biology professors and Bohart associates Fran Keller of Folsom Lake College and Dave Wyatt of Sacramento City College and headquartered at Toucan Ridge Ecology and Education Society (T.R.E.E.S) Field Station and Research Center, spanned four locations. The area boasts "some of the highest biodiversity the country has to offer," according to its website.
“Lohit and Brian Fridie (undergraduate at the University of Florida, Gainesville) captured many more individuals and more species than I ever saw on any of our trips,” said Keller, who holds a doctorate in entomology from UC Davis, where she studied with major professor Lynn Kimsey, director of the Bohart Museum and a UC Davis distinguished professor of entomology. “Granted, I was collecting everything and leading the trip but having specialists on the trip helps us gather and document insect diversity greater than we could do with just Dave and I collecting.”
“Possibly the thing that surprised me the most was the sheer underrepresentation of taxa in the country,” Garikipati said. “I had expected to maybe find one or two new country records, but I did not expect to more than double the number of species recorded from the country! The other thing that astounded me was how numerous and diverse insect populations were as well (this was my first time collecting in the tropics). Despite the sheer scope of the environment there, mantises were not an uncommon find (though they are still as a whole much more difficult to find than many insect groups).”
“It was a real pleasure searching for mantises in Belize,” Garikipati said. “My favorite find was most likely seeing wild individuals of species I'd only be able to see in pinned collections and on iNaturalist. There is something so enchanting about seeing an animal in its natural habitat, and these observations bring up many questions. It was definitely a fun experience and I am very happy to be able to contribute to our understanding of these animals.”
More Than 50 Specimens. He and his colleagues collected more than 50 specimens from 14 genera and 19 species as part of the survey. Using the specimens they collected, they generated a dichotomous key and a Lucid interactive key.
“The aim is to provide both citizens and entomologists unfamiliar with this group with an easy method to identify collected species with high accuracy,” wrote Garikipati and Bond. “Photographs in the Lucid key are included to aid with character determination.”
In their publication, the scientists thanked Julio Rivera (an entomologist at Universidad San Ignacio de Loyola in Lima, Peru) for his assistance, patience, and providing some of his unpublished work to assist in identification. “We also thank Brendon Boudinot (UC Davis doctoral alumnus) for his boundless energy, support, and methodological feedback; Philip S. Ward (professor and ant specialist at UC Davis) for assisting in identification of Formicidae; Brian T. Fridie (undergraduate at the University of Florida, Gainesville) for his assistance in collecting mantises; and one anonymous reviewer for feedback on an earlier version of the manuscript.”
Garikipati's future plans? “I am looking to continue to incorporate ecology into my comparative morphology work,” he said. “Currently, I am investigating diversity in prey capture mechanisms in mantises, which may have implications for prey specialization.” His thesis title: “Diversity of Prey Capture Mechanisms in Praying Mantises: Implication for Prey Specialization.”
“Mantises,” he said, “have long been homogenized--until relatively recently--both in terms of their behavior and morphology by the general public, and I'm hoping by showcasing diversity both in behavior and morphology, the public's perception of these animals will change. “And this research will provide us valuable insight into the impact mantises have in the ecosystems they are in, as well as their potential use as bioindicators for conservation purposes.”

Rutkowski's abstract:
"Native bees including bumble bees are important pollinators but face threats from multiple sources, including agrochemical application. Declining bumble bee populations have been linked to fungicide application, which could directly affect the fungi often found in the stored food and GI tract of healthy bumble bees. Here, we test the hypothesis that fungicides impact bee health by disrupting bumble bee -fungi interactions. Using two species, Bombus vosnesenskii and B. impatiens, we test the interactive effect of the fungicide propiconazole and fungal supplementation on the survival, reproduction, and microbiome composition of microcolonies (queenless colonies). We found that both bee species benefitted from fungi, but were differentially affected by fungicides. In B. vosnesenskii, fungicide exposure decreased survival while fungal supplementation mitigated fungicide effects. For B. impatiens, fungicide application had no effect, but fungal supplementation improved survival and offspring production. Fungicides altered fungal microbiome composition in both species, and reduced fungal abundance in B. vosnesenskii microcolonies, but not in B. impatiens, where instead fungal addition actually decreased fungal abundance. Our results highlight species-specific differences in both response to fungicides and the nature of fungal associations with bees, and caution the use of results obtained using one species to predict the responses of other species. These results suggest that fungicides can alter bee- fungi interactions with consequences for bee survival and reproduction, and suggest that exploring the mechanisms of such interactions, including interactions within bee-associated fungal communities, may offer insights into bumble bee biology and bumble bee conservation strategies.

Rutkowski completed her bachelor's degree at Cornell University, where she studied how the relationship between mycorrhizal fungi and their host plants impacts insect herbivores. On the Vannette lab website, she specifies that she studies "how bumble bees interact with the microbes, particularly fungi, in their environment, and how these relationships impact bee health."
Vannette describes her lab as "a team of entomologists, microbiologists, chemical ecologists, and community ecologists trying to understand how microbial communities affect plants and insects (sometimes other organisms too). We often study microbial communities in flowers, on insects or in soil. We rely on natural history observations, and use techniques from chemical ecology, microbial ecology and community ecology. In some cases, we study applied problems with an immediate application including pathogen control or how to support pollinators. Other questions may not have an immediate application but are nonetheless grounded in theory and will contribute to basic knowledge and conservation (e.g. how can dispersal differences among organisms affect patterns of abundance or biodiversity?)"

Gabriel Zilnik, a researcher at USDA's Agricultural Research Service, in Wapato, Wash. will be the UC Davis Department of Entomology and Nematology's next speaker.
Zilnik says the topic is of growing interest for biological researchers around the globe. "In this seminar I will attempt to demystify Artificial Intelligence and Machine Learning, assuage fears of a robot takeover, and demonstrate its utility in complex but semi-structured systems like North Carolina tobacco."
"While machine learning is based on the idea that machines should be able to learn and adapt through experience, AI refers to a broader idea where machines can execute tasks 'smartly.' Artificial Intelligence applies machine learning, deep learning and other techniques to solve actual problems.--SAS.
Zilnik holds a doctorate in entomology from North Carolina State University (2020), where he also received his master's degree in 2016. He received his bachelor's degree in anthropology from Arizona State University in 2012.
While at NCSU, he founded and hosted, Pints of Science, for two years, ending in April 2015. "I partnered with a colleague in the Department of Communication to develop an outreach program where we could provide a space for graduate students and academics to get out of their comfort zone and interact with the public," he writes on his Linked In site. "We helped our speakers develop their presentations and engage with the public in venues outside of the University."

"Since its 2008 detection in North America, management of the invasive Drosophila suzukii has primarily relied on calendar insecticide applications, creating a scenario where selection pressure from frequent insecticide
applications could result in development of insecticide resistance," Ganjisaffar says in her abstract.
"Field-derived resistance to spinosad has already been documented in California caneberry production, and there is significant concern among berry and cherry growers for development of resistance to other insecticides," she wrote. "This seminar will present the status of our ongoing studies to assess development and extent of insecticide resistance in California D. suzukii populations, seasonal changes in resistance, stability of resistance and potential cross-resistance between chemical classes, as well as our work on the behavioral control of D. suzukii and evaluating the efficacy of some Attract-and-Kill products."
Ganjisaffar joined the Zalom lab in August 2020 from UC Riverside where she served as a postdoctoral scholar after receiving her doctorate in entomology there in 2016. She was a member of the UC Riverside team that won second place in theESA's Linnaean Games (now Entomology Games). She received a University of California Dean's Distinguished fellowship in 2011.

Kyle Lewald's abstract
Tuta absoluta represents one of the largest threats to tomato production worldwide. While initially contained to South America throughout the 20th century, T. absoluta were detected in Spain in 2006 before rapidly spreading throughout Europe and Asia over the next decade. To facilitate study of pesticide resistance, adaptation, and control strategies, researchers require a high quality, highly contiguous, and well-annotated genome assembly. The currently published genome assembly was generated using short-read technology for the purpose of developing molecular markers and studying population genetics; however, due to the genome's large size, heterozygosity, and repetitiveness, the assembly was highly fragmented, making it unsuitable for annotation or functional genomic studies. To address this, we extracted DNA from a single T. absoluta individual for sequencing with long-read PacBio HiFi technology to avoid assembly issues expected due to high genetic diversity and repetitiveness. We have now successfully created a diploid assembly that contains 98% of complete BUSCO groups and 99% of initial raw reads, with an N50 of 6Mb. The genome is 3% heterozygous, and is 60% composed of repeat elements, explaining the fragmented nature of the previous assemblies. By annotating this assembly with previously published RNAseq, protein, and repeat-element datasets, we expect this resource to advance efforts in understanding and developing control strategies for this invasive moth.
