The Lycaenid Butterfly Fauna (Lepidoptera) Of Cosñipata, Peru: Annotated Checklist, Elevational Patterns, And Rarity, Gerardo Lamas, Michael L. Mcinnis, Robert C. Busby, Robert K. Robbins

Insecta Mundi

Peru’s Cosñipata Region in Cuzco and Madre de Dios Departments is a valley between Manu National Park and the Amarakaeri Communal Reserve that ranges from 400 to 4,000 m elevation. A team of experienced lepidopterists sampled the butterfly fauna of this valley for more than a decade (7,440 field person-hours). We analyze the data for Lycaenidae (Lepidoptera: Papilionoidea), a family for which we have taxonomic expertise. After adding data on the fauna from museums and the literature, we present an annotated checklist of the 340 Lycaenidae species recorded from the Cosñipata Region with notes for each species on the elevations …

Design, Simulation And Testing Of Biomimetic Directional Acoustic Sensors, Brendan Francis

Thinking Matters Student Research Symposium

The Ormia ochracea, a species of parasitic fly, has become the focal point in sound localization research because of its finely tuned hearing abilities. The female of this species uses its super highly directional hearing to pinpoint the call of a host cricket, with hypersensitivity of frequency and phase difference, to reach and dispose of its eggs on the host. The goal of this study was to further the research of a previous Project in Professor Guvench’s group which implemented MEMS (Micro Electro-Mechanical System) technology on a chip to replicate these abilities. In this iteration, however, some commercially available …

Mems Directional Acoustic Sensors, Colby Damren

Thinking Matters Student Research Symposium

The purpose of my project is to test and verify two Micro-Electro-Mechanical-System (MEMS) microphones. The two MEMS devices are biomimetic microphones that imitate the eardrums of the Ormia Ochracea, a parasitic fly that listens for host crickets to lay their eggs. The MEMS microphones mimic the eardrum spacing of the Ormia Ochracea with a spacing of 1000um. This is roughly twice the opening of the Ormia Ochracea. The microphones will be tested for directionality inside a wooden box. This box will be lined with beveled foam to prevent any echo or outside noise from interfering with the results. These results …

How Do Vanhorniidae (Hymenoptera) Parasitize Eucnemidae (Coleoptera)?, Jyrki Muona

Insecta Mundi

The relationship between the beetle family Eucnemidae and the parasitic proctotrupoid family Vanhorniidae is discussed. The only proven host for Vanhornia eucnemidarum Crawford in North America is an undetermined species of the genus Isorhipis Boisduval and Lacordaire. In Europe, the only known host for Vanhornia leileri Hedqvist is Hylis cariniceps (Reitter). The biologies of the hosts differ radically and it ap­pears unlikely that they could be parasitized in a typical proctotrupoid fashion in which eggs are placed in or on the host larva. This supports the hypothesis that small Vanhorniidae larvae attach themselves to the newly hatched beetle larvae, before …

Los piojos pertenecen al orden Phthiraptera y generalmente se dividen en dos grupos según las piezas bucales y las preferencias alimentarias. Los piojos masticadores (Mallophaga) tienen mandíbulas bien desarrolladas y comen piel, plumas y pelaje de aves y mamíferos.

208— Describing Genetic Diversity In A Non-Native Ant-Mimicking Spider, Cassidy Mills, Jennifer L. Apple

GREAT Day Posters

The ant-mimicking spider Myrmarachne formicaria (Salticidae) is a species native to Eurasia and was first identified in North America in 2001. It has since been found in many locations in the Northeast including western New York, western Pennsylvania, northeastern Ohio, and southern Ontario. Little is known about its introduction to North America and how it has dispersed since. By characterizing the mitochondrial genetic diversity of this species, we can learn about its introduction history and dispersal patterns in North America. Sequencing of a 600-bp mitochondrial DNA gene region spanning the 16s rRNA, leucine tRNA, and part of the ND1 gene …

Exploring The Kairomone-Based Foraging Behaviour Of Natural Enemies To Enhance Biological Control: A Review, Pascal M. Ayelo, Christian W.W. Pirk, Abdullahi A. Yusuf, Anaïs Chailleux, Samira A. Mohamed, Emilie Deletre

All Peer-Reviewed Publications

Kairomones are chemical signals that mediate interspecific interactions beneficial to organisms that detect the cues. These attractants can be individual compounds or mixtures of herbivore-induced plant volatiles (HIPVs) or herbivore chemicals such as pheromones, i.e., chemicals mediating intraspecific communication between herbivores. Natural enemies eavesdrop on kairomones during their foraging behaviour, i.e., location of oviposition sites and feeding resources in nature. Kairomone mixtures are likely to elicit stronger olfactory responses in natural enemies than single kairomones. Kairomone-based lures are used to enhance biological control strategies via the attraction and retention of natural enemies to reduce insect pest populations and crop damage …

Insects Provide Unique Systems To Investigate How Early-Life Experience Alters The Brain And Behavior, Rebecca R. Westwick, Clare C. Rittschof

Entomology Faculty Publications

Early-life experiences have strong and long-lasting consequences for behavior in a surprising diversity of animals. Determining which environmental inputs cause behavioral change, how this information becomes neurobiologically encoded, and the functional consequences of these changes remain fundamental puzzles relevant to diverse fields from evolutionary biology to the health sciences. Here we explore how insects provide unique opportunities for comparative study of developmental behavioral plasticity. Insects have sophisticated behavior and cognitive abilities, and they are frequently studied in their natural environments, which provides an ecological and adaptive perspective that is often more limited in lab-based vertebrate models. A range of cues, …

Correlation Between Abundance Of Fossils In Harvester Ant Nest And Proximity Of Fossil Sites, Hayeong Woo

Campus Research Month

Harvester ants have an interesting behavior of bone collecting. Therefore, harvester ant nests that are positioned around the fossil sites contain various fossil fragments. If there is a statistically significant correlation between the abundance of fossil fragments and the distance of the ant nests from the main fossil sites, ant nests can potentially be used to predict the proximity of the main fossil sites.

Development Of A Rapid Drug Detection Method For Insects Using Paper Spray Ionization Mass Spectrometry (Psi-Ms), Alexandria Plyler

Undergraduate Research and Scholarship Symposium

Insects have the ability to reflect the chemical environment that they have developed in. Thus, necrogenous insects can reflect the chemical environment of cadavers they have fed on. Forensic scientists can potentially utilize insect larvae as an alternate biological matrix to detect drugs in cadavers that are skeletonized, burned, or otherwise badly damaged. Analysis of insects using paper spray ionization mass spectrometry (PSI-MS), an analytical method requiring little to no sample preparation, could prove a rapid, cost-effective, and non-destructive alternative form of toxicological analysis. Traditional tissue analysis via GC and LC-MS often require lengthy sample preparation, use expensive reagents, and …

High Tunnel Pest Management - Aphids, Nick Volesky, Zachery R. Schrumm

All Current Publications

Aphids are a common pest found on high tunnel crops such as fruits, vegetables, ornamentals, grasses, and weeds. Four aphid species commonly found in Utah in high tunnels are green peach aphid (Myzus persicae), melon aphid (Aphis gossypii), potato aphid (Macrosiphum euphorbiae), and cabbage aphid (Brevicoryne brassicae). This fact sheet describes different aphids and reviews the aphid life cycle. It also addresses how to monitor for damage caused by aphids and cultural, biological, and chemical controls.

Soybean Gall Midge In Nebraska, Anthony J. Mcmechan, Thomas Hunt, Robert J. Wright

Eastern Nebraska Research, Extension, and Education Center

Soybean gall midge (Resseliella maxima Gagné) was described in 2019 as a new insect species in Nebraska, due to observations of widespread early season injury in eastern Nebraska, eastern South Dakota, western Iowa, and southwest Minnesota soybean fields (Gagné et al., 2019). Since its discovery, soybean gall midge has been causing significant injury and yield losses in soybean in eastern Nebraska. Although only recently identified, soybean gall midge is not likely new to the north- central region of the U.S. In 2011, orange larvae were documented in some isolated fields in northeast Nebraska that had received hail damage during the …

Determination Of The Presence Of Rickettsia Spp. And Borrelia Spp. Carried By Tortoise Ticks From Madagascar, Anna Phan

Biological Sciences Theses & Dissertations

Ticks were removed from three species of Malagasy tortoises, Astrochelys yniphora, A. radiata, and Pyxis arachnoides (comprising two subspecies P. a. arachnoides and P. a. oblonga), between 2012 and 2015. The ticks were presumed to be from the genus Amblyomma. Ticks were morphologically identified and then checked molecularly to confirm their classification or identify any ticks that could not be morphologically identified. Molecular identification was done via end-point PCR that amplified tick cytochrome oxidase (CO1) and tick 12S rRNA genes. Ticks were screened via a real-time polymerase chain reaction assay for the presence of Rickettsia spp. …

Managing And Monitoring Genetic Isolation And Local Adaptation Of Endemic And Introduced Cotesia Sesamiae For The Biological Control Of The Cereal Stemborer Busseola Fusca In Cameroon, Rose Ndemah, Bruno Pierre Le Ru, Claire Capdevielle-Dulac, Fritz Schulthess, Laure Kaiser, Rachid Hanna, Alexandre Depoilly, Julius Obonyo, Paul André Calatayud, Albert Abang, Stéphane Dupas

All Peer-Reviewed Publications

The success of biological bontrol (BC) introductions can be enhanced by considering theory and knowledge of biological systems. The gregarious braconid parasitoid Cotesia sesamiae (Cameroon) is one of the best studied biological control agent from the perspective of molecular ecology. Its evolutionary adaptation to the target host involves symbiotic partners. Polydnaviruses are responsible for immune and developmental adaptations whereas Wolbachia bacteria may reinforce this local adaptation though genetic isolation mechanisms. The noctuid Busseola fusca is a major stemborer pest of maize in sub-Saharan Africa. In contrast to eastern Africa, C. sesamiae is rarely found on B. fusca in western Africa. …
