Maize Terpene Synthase 1 Impacts Insect Behavior Via The Production Of Monoterpene Volatiles Β-Myrcene And Linalool, Jessica P. Yactayo-Chang, Geoffrey T. Broadhead, Robert J. Housler, Marcio F.R. Resende Jr., Kashish Verma, Joe Louis, Gilles J. Basset, John J. Beck, Anna K. Block

Department of Entomology: Faculty Publications

Plant-derived volatiles are important mediators of plant-insect interactions as they can provide cues for host location and quality, or act as direct or indirect defense molecules. The volatiles produced by Zea mays (maize) include a range of terpenes, likely produced by several of the terpene synthases (TPS) present in maize. Determining the roles of specific terpene volatiles and individual TPSs in maize-insect interactions is challenging due to the promiscuous nature of TPSs in vitro and their potential for functional redundancy. In this study, we used metabolite GWAS of a sweetcorn diversity panel infested with Spodoptera frugiperda (fall armyworm) to identify …

Importance Of Sanitation For Stored-Product Pest Management, Georgina Bingham, David W. Hagstrum

Department of Entomology: Faculty Publications

Sanitation is essential for the cost-effective pest management of stored-product insects. The Food, Drug and Cosmetic Act of 1938 led to the Food and Drug Administration (FDA) tightening regulatory standards, and many local surveys, courses and conferences were organized to prepare the industry for these new regulations. Sanitation removes insects and residual food, which may also provide shelter for insects, with heat treatments and insecticide applications. The number of insects removed by cleaning may be reduced as the number of available hiding places increases. Decreased sanitation negatively affects the efficacy of most other pest management practices, with means of 1.3- …

Genomic Analysis Reveals New Species And Subspecies Of Butterflies, Jing Zhang, Qian Cong, Jinhui Shen, Leina Song, Nick V. Grishin

The Taxonomic Report of the International Lepidoptera Survey

Large-scale genomic sequencing of butterfly taxa reveals new findings that are presented here. While we focus on detecting species by comparative genomics and define subspecies as groups of populations genetically differentiated from each other but not as strongly as species (that is, subspecies as species in the making), we report other adjustments to butterfly classification. As a result, 4 subgenera, 11 species, and 6 subspecies are proposed as new. New subgenera are: Rapis Grishin, subgen. n. (type species Papilio rapae Linnaeus, 1758, genus Pieris Schrank, 1801) in Pieridae Swainson, 1820 and Callitera Grishin, subgen. n. (type species Eurygona? pulcherrima …

Reassessment Of Amblyscirtes Hegon (Hesperiidae) As A Complex Of Four Distinct Species Revealed By Genomic Analysis, Harry Pavulaan, Ricky Patterson, Nick V. Grishin

The Taxonomic Report of the International Lepidoptera Survey

After the discovery of a unique phenotype in the southern United States with a different ventral ground color than nominotypical Amblyscirtes hegon (Scudder, 1863), which occurs in the northeastern United States, genomic analysis revealed that A. hegon is a species complex. Phenotypic, genitalic, and genomic differences of the complex are presented here. Four species are identified: A. hegon; A. nemoris (W. H. Edwards, 1864), stat. rest.; A. matheri Patterson, Pavulaan & Grishin, sp. n. (TL: USA, Mississippi, Warren County); and A. gelidus Grishin, Patterson & Pavulaan, sp. n. (TL: USA, Michigan, Van Buren County).

Can The Vegetation Structure And Composition In Urban Green Spaces Determine Diversity Of Green Lacewings (Neuroptera: Chrysopidae)?, Jose I. Martinez, Raiza J. Castillo, Adrián Ardila-Camacho, Charles V. Covell, José Isabel López-Arroyo, Francisco Javier Nava-Guízar

Insecta Mundi

Green spaces represent the only natural areas in several cities around the world, providing good shelters for the local fauna. Based on this premise, many ecological studies have been conducted focused on these areas. Most of these works are about insects, particularly butterflies and beetles. Our study is centered on a different group: green lacewings (Neuroptera: Chrysopidae). These insects exhibit a similar feeding behavior to some other groups, such as beetles. We estimated diversity, richness, distribution, abundance and similarity employing two methods: sweep netting and suction trapping. Also, oviposition hosts were identified in 20 different green spaces. Approximately 740 specimens …

Genomics-Based Taxonomic Rearrangement Of Achlyodini And Carcharodini (Lepidoptera: Hesperiidae: Pyrginae), Jing Zhang, Qian Cong, Jinhui Shen, Leina Song, Nick V. Grishin

Insecta Mundi

Genomic analysis of Pyrginae Burmeister, 1878 (Lepidoptera: Hesperiidae Latreille, 1809) with an emphasis on the tribes Achlyodini Burmeister, 1878 and Carcharodini Verity, 1940 reveals many incon­sistencies between the resulting phylogeny and the current classification. These problems are corrected by proposing new taxa, changing the ranks of others, or synonymizing them, and transferring species between genera. As a result, five subtribes, one genus, 20 subgenera, and one species are proposed as new: Cyclo­semiina Grishin, new subtribe (type genus Cyclosemia Mabille, 1878), Ilianina Grishin, new subtribe (type genus Iliana E. Bell, 1937), Nisoniadina Grishin, new subtribe (type genus Nisoniades Hübner, [1819]), …

Defensive Behaviors Of The Mealybug Nipaecoccus Nipae (Maskell, 1893) (Hemiptera: Pseudococcidae) And The Green Lacewing Ceraeochrysa Claveri (Navás, 1911) (Neuroptera: Chrysopidae), With Videos Of Dorsal Packet Loading And Mealybug Ostiole Function, Erin C. Powell

Insecta Mundi

The interactions between the lacewing Ceraeochrysa claveri (Navás) (Neuroptera: Chrysopidae) larva and the coconut mealybug Nipaecoccus nipae (Maskell) (Hemiptera: Pseudococcidae) were recorded. The third-instar lacewing larva constructed a dorsal packet using mealybug wax from both male pupal cases and the bodies of adult females. Surprisingly, live nymphs were also frequently placed into the dorsal packet. Prey mealybugs were discarded and not incorporated into the packet after consumption. When disturbed, adult female mealybugs reflex bled from their dorsal ostioles, contacting the mouthparts of the lacewing. The lacewing quickly retreated to clean the mouthparts on the substrate, providing further evidence that ostiolar …

Predicting The Potential Distribution In South Korea Of Two Mealybug Species (Hemiptera: Pseudococcidae) Intercepted On Pineapples In Quarantine, S Bin Kim, Soo-Jung Suh

Insecta Mundi

Dysmicoccus brevipes (Cockerell) and Dysmicoccus neobrevipes Beardsley are major pests of pine­apples, ornamentals, and vegetable crops in many countries around the world. The potential distribution of these mealybug pests into South Korea remains a prime concern because of their high incidence in intercep­tions screened during inspection. Hence, these species prompted a modelling effort to assess their potential risk of introduction. Potential risk maps were developed for these pests with the CLIMEX model based on occurrence records under environmental data. The potential distribution of these pests in South Korea in the 2020s, 2050s and 2090s is projected based on the RCP …

Using Genetic Comparisons Of Populations From Arizona, Mexico, And Texas To Investigate Fall Armyworm Migration In The American Southwest, Rodney N. Nagoshi, Ashley E. Tessnow, Yves Carrière, Jeff Bradshaw Dr., Kyle Harrington, Gregory A. Sword, Robert L. Meagher

Department of Entomology: Faculty Publications

Fall armyworm (FAW) is a global agricultural pest, causing substantial economic losses in corn and many other crops. Complicating efforts to control this pest is its capacity for long distance flights, which has been described in greatest detail for the central and eastern sections of the United States. FAW infestations are also routinely found in agricultural areas in southern Arizona, which lie beyond the western limits of the mapped migratory pathways. Climate suitability analysis found that the affected Arizona locations cannot support permanent FAW populations, indicating that these FAW most likely arise from annual migrations. A better understanding of this …

Disruption Of Semiochemical-Mediated Movement By The Immature Trogoderma Variabile Baillon And Trogoderma Inclusum Le Conte (Coleoptera: Dermestidae) After Exposure To Long-Lasting Insecticide-Incorporated Netting, Sabita Ranabhat, Michael J. Domingue, Luke Lebar, Georgina Bingham, Kun Yan Zhu, William R. Morrison Iii

Department of Entomology: Faculty Publications

BACKGROUND: Highly mobile stored product insects may be able to readily orient in response to food cues and pheromones to attack durable commodities at each link of the postharvest supply chain. A 0.4% deltamethrin-incorporated long-lasting insecticide-incorporated netting (LLIN) is a successful novel preventative integrated pest management (IPM) tactic to intercept dispersing insects after harvest. However, it is unknown whether exposure to LLIN may affect olfaction and orientation to important semiochemicals by immature stored product dermestids, therefore the aim of this study was to assess whether exposure to LLIN disrupts the normal olfactory and chemotactic behavior of warehouse beetle, Trogoderma variabile …
