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.

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.

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 …

Photonic Monitoring Of Atmospheric Fauna, Adrien P. Genoud

Dissertations

Insects play a quintessential role in the Earth’s ecosystems and their recent decline in abundance and diversity is alarming. Monitoring their population is paramount to understand the causes of their decline, as well as to guide and evaluate the efficiency of conservation policies. Monitoring populations of flying insects is generally done using physical traps, but this method requires long and expensive laboratory analysis where each insect must be identified by qualified personnel. Lack of reliable data on insect populations is now considered a significant issue in the field of entomology, often referred to as a “data crisis” in the field. …

Establishment Of The Invasive Cactus Moth, Cactoblastis Cactorum (Berg) (Lepidoptera: Pyralidae) In Pakistan: A Potential Threat To Cultivated, Ornamental And Wild Opuntia Spp. (Cactaceae), Muhammad Ather Rafi, Harry Pavulaan, Muhammad Islam, Muhammad Ashfaq, Haseeb Kamran, Walija Fayaz, Gul Naz Parveen, Riffat Sultana, Ahmad Zia, Waqar Ahmed, Qudrat Ullah, Muhammad Qasim, Falak Naz, Nazeer Ahmed, Muhammad Tariq Khan, Muhammad Saeed, Jalal Hayat Khan

The Taxonomic Report of the International Lepidoptera Survey

Subsequent to the significant accomplishment of biological control of Opuntia weeds in Australia, the larvae of the cactus moth, Cactoblastis cactorum (native to parts of South America), were released in many countries for the biological control of native Opuntia species (Simmonds and Bennett, 1966). Inauspiciously, larvae were also released in the Caribbean, where the moth spread naturally and by the human support all over the region (García-Turudi et al., 1971). Its enhanced dissemination rate and the biological potential for invasiveness, suggests that the cactus moth is likely to become an invasive pest of Opuntia in the Southeast United States, Mexico, …
