A Novel Insect And Pest Identification Model Based On A Weighted Multipath Convolutional Neural Network And Generative Adversarial Network, Vinita Abhishek Gupta, M.V. Padmavati, Ravi R. Saxena, Raunak Kumar Tamrakar

Karbala International Journal of Modern Science

Timely identification of insects and their management play a significant role in sustainable agriculture development. The proposed hybrid model integrates a weighted multipath convolutional neural network and generative adversarial network to identify insects efficiently. To address the shortcomings of single-path networks, this novel model takes input from numerous iterations of the same image to learn more specific features. To avoid redundancy produced due to multipath, weights have been assigned to each path. For Xie2 dataset, the model shows 3.75%, 2.74%, 1.54%, 1.76%, 1.76%, 2.74 %, and 2.14% performance improvement from AlexNet, ResNet50, ResNet101, GoogleNet, VGG-16, VGG-19, and simple CNN respectively. …

Investigating The Potential Role Of Termites As Pathogen Vectors In The Decline Of Ironwood Trees (Casuarina Equisetifolia) In Guam, Garima Setia

LSU Master's Theses

Termites have been found associated with the decline of Casuarina equisetifolia (ironwood), an important agro-forestry species in Guam. While the ironwood tree decline (IWTD) was first reported in 2002, its association with termites as well as with bacteria Ralstonia solanacearum and Klebsiella species (K. oxytoca and K. variicola) was determined in 2010 and 2012 respectively. In 2019, the termite species attacking the ironwood trees were identified as Nasutitermes takasagoensis, Coptotermes gestroi, and Microcerotermes crassus. However, the role of termites in IWTD is not known. Since termites are repositories of bacteria and consume wood, termite foragers might …

Emerald Ash Borer (Agrilus Planipennis [Fairmaire]), Emily A. Parent, Lori R. Spears, Ryan S. Davis, Ricardo Ramirez

All Current Publications

Emerald ash borer (Order: Coleoptera: Family Buprestidae) (EAB) is an invasive wood-boring insect that infects the true ash species (Fraxinus spp.). EAB is native to parts of China, Korea, Japan, Taiwan, and small areas of Russia and Mongolia. EAB was first discovered in North America in June 2002 near Detroit, Michigan, and Windsor, Ontario, Canada, and is thought to have arrived to North America via infested wood packing material. EAB is generally established in an area for several years before it is detected and can spread over large areas through active flight and human-mediated dispersal.

Department of Entomology: Faculty Publications

Background Adaptations by arthropod pests to host plant defenses of crops determine their impacts on agricultural production. The larval host range of western corn rootworm, Diabrotica virgifera virgifera (Coleoptera: Chrysomelidae), is restricted to maize and a few grasses. Resistance of D. v. virgifera to crop rotation practices and multiple insecticides contributes to its status as the most damaging pest of cultivated maize in North America and Europe. The extent to which adaptations by this pest contributes to host plant specialization remains unknown.

Results A 2.42 Gb draft D. v. virgifera genome, Dvir_v2.0, was assembled from short shotgun reads and scaffolded …

Characterization Of Antiviral Immunity, Host Virus Interactions, And Toxicity Of Agrochemical Residues In The Western Honey Bee, Christopher Fellows

LSU Doctoral Dissertations

Honey bee colonies have perished at an alarming rate for over 15 years. Among the multitude of threats to bee health, virus infections and agrochemical exposure appear to be major drivers of colony loss. As virus infection is among the most damaging influences on bee health, we first investigated a putative target for antiviral immunity, termed K_ATP channels. We previously demonstrated that pharmacologically activating K_ATP channels induces the production of reactive oxygen species and increases survival during infection with Israeli Acute Paralysis Virus. Here, we demonstrate that K_ATP modulation and ROS induction reduce virus replication and enhance …

Taxonomic Notes On The Luciolinae (Coleoptera: Lampyridae), Oliver Keller, Lesley Ballantyne

Insecta Mundi

Several nomenclatural changes for taxa in the firefly subfamily Luciolinae (Coleoptera: Lampyri­dae) are proposed. Evidence is presented to correct the year of description for Luciola dregei Motschulsky 1853 to Motschulsky 1854 when the name was ratified. We correct the authorities and years of descriptions for type species designations for the genera Delopleurus Motschulsky, 1853, and Delopyrus Motschulsky, 1853 to Motschulsky 1854 for both. All remaining taxa described as variations in the subfamily Luciolinae by McDermott (1966), are evaluated to subspecies with their availability determined based on ICZN (1999) Article 45.6.

The southernmost record for Chrysobothris piuta Wick­ham, from Baja California, Mexico, is established. A specimen of the Argentinian Chrysobothris rugosa Gory and Laporte labeled from Florida is reported. A lectotype for Chrysobothris vulcanica LeConte is newly designated.

A New Species Of Biclonuncaria Razowski And Becker, 1993 (Lepidoptera: Tortricidae: Polyorthini) From Costa Rica, John W. Brown

Insecta Mundi

Biclonuncaria recurvana, new species (Lepidoptera: Tortricidae: Polyorthini), is described and il­lustrated from Area de Conservación Guanacaste in northwestern Costa Rica. It is most similar to B. conica Razowski, 1993, from Mexico, but the two are easily distinguished by features of the male genitalia. Biclo­nuncaria recurvana has been reared (n = 12 specimens) from field-collected larvae feeding on the leaves of Dalbergia glomerata Hemsley (Fabaceae), consistent with the previously reported host plant for B. dalbergiae Razowski and Becker, 1993, which has been reared from Dalbergia in Brazil.

Minute Pirate Bug And Big-Eyed Bug Populations In Pyramided Bt Sweet Corn Bordered By Native Perennial And Pasture Border Rows, Hanna Waller, John D. Sedlacek, Karen L. Friley, Jenny Galvin, Anjana Duwal

Posters-at-the-Capitol

Sweet corn is an important vegetable crop grown in Kentucky. The major sweet corn ear pests are European corn borer, Ostrinia nubilalis, and corn earworm, Helicoverpa zea. Ecological control measures have been introduced to manage these pests, reducing use of broad spectrum insecticides. Conservation biological control (CBC) is a component of these approaches. CBC manages pests in agroecosystems using habitat management to enhance populations of natural enemies that are already present in the system. Another important advancement is the cultivation of Bacillus thuringiensis (Bt) sweet corn resistant to the Lepidopteran corn ear pests. This study used CBC of corn ear …

Subgenera Of Dacne Latreille, 1797 (Erotylidae: Erotylinae: Dacnini) Given Full Generic Rank, Paul E. Skelley

Insecta Mundi

Previously described subgenera of Dacne Latreille, 1797 (Coleoptera: Erotylidae) show charac­ter states and combinations implying closer relationships with genera other than with Dacne, suggesting “Dacne” is not monophyletic. These characters are briefly discussed along with the genera sharing the charac­ters. To improve the current classification, the subgenera of Dacne are raised to generic status as: Afrodacne Delkeskamp, 1954, Ameridacne Skelley, 2009, and Xenodacne Boyle, 1956. A checklist of all species included in these genera is presented, updating generic combinations as needed.

Untangling The Complex Interactions Between Turtle Ants And Their Microbial Partners, Manuela O. Ramalho, Corrie S. Moreau

Biology Faculty Publications

Background: To understand the patterns of biodiversity it is important to consider symbiotic interactions as they can shape animal evolution. In several ant genera symbiotic interactions with microbial communities have been shown to have profound impacts for the host. For example, we know that for Camponotini the gut community can upgrade the host's diet and is shaped by development and colony interactions. However, what is true for one ant group may not be true for another. For the microbial communities that have been examined across ants we see variation in the diversity, host factors that structure these communities, and the …

Entomology Outreach Presentations To Four Audiences, Michael Goldman

Department of Entomology: Distance Master of Science Projects

I proposed that my master’s Project would be outreach on Entomology at four levels: School aged children, laymen, non-entomologists in a technical field, and entomologists. The idea here is basically how to talk about entomology to varying levels of expertise, from first graders to experts in both entomology and occupational health and safety. Presentations were given to audiences at each of the four levels. The specific topics varied for each audience. The determination was made by the inviting audience in the cases of school aged children and adult laymen and by me in the cases of Occupational Safety and Health …
