A Note On Psoloessa Texana And Achurum Sumichrasti (Orthoptera: Acrididae: Acridinae) From Louisiana, Jovonn G. Hill

Midsouth Entomologist

During a 2024 survey in Kisatchie National Forest, Louisiana, Psoloessa texana and Achurum sumichrasti were collected, representing new state records. No prior records of P. texana exist for Louisiana, and while A. sumichrasti has been observed and reported online, no specimens were previously documented. These findings extend the known range of P. texana by ~320 km and suggest a broader distribution for A. sumichrasti. Their presence in xeric savannas may reflect Pleistocene-era disjunctions. With these additions, Louisiana’s documented grasshopper fauna increases to 41 species.

Bioassay To Evaluate Resistance Levels In Tarnished Plant Bug (Hemiptera: Miridae) Populations In Alabama To Common Cotton Insecticides, T. J. Douglas, K. Kesheimer, A. Jacobson, S. Brown, F. R. Musser, L. S. Catchot, S. H. Graham

Midsouth Entomologist

The tarnished plant bug, Lygus lineolaris (Palisot de Beauvois), has emerged as the major insect pest of cotton in the mid-southern United States following the eradication of the boll weevil and the introduction of genetically modified Bt cotton for caterpillar pests. The objective of this study is to evaluate tarnished plant bug resistance to the five most common insecticides used for control across six distinct growing regions. Glass-vial bioassays were used to evaluate resistance of field populations in a laboratory setting. Elevated levels of resistance of tarnished plant bug to bifenthrin and, to a lesser degree, imidacloprid have been reported …

Ground Truthing Of Inaturalist Submissions Confirms The Presence Of Asian Needle Ants, Brachyponera Chinensis (Emery) (Hymenoptera: Formicidae), In Louisiana, A New State Record, Aaron R. Ashbrook, Victoria Bayless, Stephen Baca, Gerardo Guevara-Milla, Chris E. Carlton

Midsouth Entomologist

Based on submissions to iNaturalist from citizen scientists, the presence of the Asian needle ant (Brachyponera chinensis), was confirmed for Louisiana in East Baton Rouge Parish. Use of citizen scientist platforms for sources of invertebrate taxa distributions is a powerful tool but requires caution because the records are typically not validated by physical voucher specimens that have been deposited in publicly accessible museums, and identification of many species is not possible by images alone. To demonstrate the usefulness of citizen scientist programs like iNaturalist, possible collection sites for Asian needle ant specimens were located. Specimens were collected, identified, and vouchers …

2024 Soybean Insect Losses In The United States, Fred R. Musser, Sebe A. Brown, Tim Bryant, Whitney D. Crow, Jeffrey A. Davis, Christina Difonzo, Chase Floyd, Scott H. Graham, Jeremy K. Greene, Kelly A. Hamby, David Kerns, Janet Knodel, David Owens, Dominic D. Reisig, Phillip M. Roberts, Nicholas J. Seiter, Adam J. Sisson, Benjamin C. Thrash, Kelley J. Tilmon, Raul T. Villanueva

Midsouth Entomologist

Estimated management costs and losses due to insects and other invertebrates in soybean during the 2024 growing season were collected and compiled from 19 states to provide a record of insect pressure and management practices for the year. These annual estimates provide a historical record of pest pressure and insect management and have been compiled in some states since 2004. Participating states represented 63% of soybean acreage grown in the United States, with near 100% participation in southern states. Overall, the stink bug complex was the costliest insect pest in soybean followed by corn earworm and soybean looper. Total insect …

A Technique For Estimating The Number Of Shoots On Pole-Sized Red Pine: The Relationship Of Selected Tree Parameters To Number Of Shoots In Central Wisconsin Sand Plains Plantations, J. H. Hainze, D. M. Benjamin

The Great Lakes Entomologist

Diameter at breast height (dbh) , of ten tree parameters tested, was most highly correlated with the number of shoots per tree in six red pine plantations in the central Wisconsin sand plains. Tree height, frequently used as an estimator of shoot number in young conifers, was not highly correlated with shoot number. A strong, nonlinear correlation existed between branch diameter and number of shoots per branch. Multiple regressions using several tree parameters yielded the highest R2 values, however, dbh was judged the simplest and most practical estimator of shoot number for central Wisconsin red pine plantations.

Effect Of Artificial Defoliation On Broccoli Yield, W. S. Cranshaw, R. J. Default

The Great Lakes Entomologist

Broccoli plants were artificially defoliated at varying plant growth stages and defoliation intensities to determine bases for control decisions with lepidopterous defoliators. Low levels of defoliation (<25%) did not significantly depress head weight at any treatment date. Higher levels of defoliation severity (50%) depressed head weight when inflicted following the development of small (<2 cm) heads. Only complete defoliation (100%) consistently affected head weights. Because of the great ability of broccoli plants to compensate for leaf loss, most pre heading insecticide applications should be able to be eliminated in Minnesota without yield losses.

Sewage Sludge Application Linked To Increase In Eastern Tent Caterpillar Populations (Lepidoptera: Lasiocampidae), Louis F. Wilson, John H. Cooley, William J. Mattson

The Great Lakes Entomologist

Numbers of Malacosoma americanum caterpillar tents were positively correlated with average numbers and biomass of cherry trees as well as with amount of sludge applied. The enhancing effect of sewage sludge on amounts of black cherry biomass and foliar nitrogen may have been the principal factors leading to higher tent caterpillar populations on fertilized plots.

Record Of Michigan Mosquito Species (Diptera: Culicidae) Collected In A Natural Focus Of Jamestown Canyon Virus In 1984, Paul R. Grimstad, Michael J. Mandracchia

Data are presented on the seasonal succession of 22 species of mosquitoes collected at the Houghton Lake Wildlife Research Area, Missaukee County, in northcentral Michigan during a three-month period in 1984. Nine species represent new county records.

Observations On The Nesting And Unique Cachement Behavior Of Calicurgus Hyalinatus (Hymenoptera: Pompilidae), Frank E. Kurczewski, Margery G. Spofford

The Great Lakes Entomologist

The components of the nesting and provisioning behavior of Calicurgus hyalinatus are delineated chronologically. The unique cachement of the prey, whereby the spider is suspended from vegetation by its own silken threads, is described. The nesting and provisioning components we observed are compared with those described in the Nearctic and Palearctic literature.

Nearctic Epiblema: A New Synonymy, A Revised Identity, And Two New Species (Lepidoptera: Tortricidae), William E. Miller

The Great Lakes Entomologist

New findings are reported for four species: Epiblema naoma Clarke is a junior synonym of E. iowana McDunnough; E. numerosana (Zeller) is currently misidentified; E. chromata, currently identified as the preceding, is described from Texas and differentiated from E. grossbecki Heinrich by maculation and female genitalia; and E. arctica, recently discovered in the Alaskan tundra, is described and differentiated from the boreal E. lyallana McDunnough by maculation and male genitalia.

Winter Wheat Cold Hardiness And Fructan Reserves Affected By Rhopalosiphum Padi (Homoptera: Aphididae) Feeding, S. G. Wellso, C. R. Olien, R. P. Hoxie

The Great Lakes Entomologist

The cold hardiness of 'Winoka' and 'Genesee' winter wheats was each significantly less (P = 0.05) when fed upon by bird-cherry oat aphids, Rhopalosiphum padi, than non-infested seedlings. Aphid feeding also reduced the amount of fructans in crown tissue ca. 20% compared to extracts from crowns of non-infested seedlings. It appears that the cold hardiness of these wheat cultivars may have been reduced because of fructan depletion by insect feeding.

Control Of Hyadaphis Tataricae (Homoptera: Aphididae) On Honeysuckle Including Observations On Host Plant Resistance, Philip L. Nixon, Carolyn Peet Nixon, James E. Schuster

The Great Lakes Entomologist

llyadaphis tataricae causes witches-brooming to the growing tips of Zabelii and other large bush-type honeysuckles in the north central states. Insecticide tests show that acephate (Orthene), dimethoate (Cygan), or oxydemeton-methyl (Metasystox-R) sprayed monthly in June and July will reduce witches-brooming. Malathion was not effective in reducing damage. Host plant resistance observations indicate that Lonicera x notha, L. x muendeniensis, L. x amoena 'Alba', L. x ).;ylosteoides, and L. tatarica 'Arnold Red' are ll. tataricae resistant. These large bush-type honeysuckles would appear to be good replacements for Zabelii and other susceptible honeysuckles in ornamental plantings.

Vulnerability Of Hybrid Populus Nursery Stock To Injury By The Tarnished Plant Bug, Lygus Lineolaris (Hemiptera: Miridae), Louis F. Wilson, Lincoln M. Moore

The Great Lakes Entomologist

The tarnished plant bug injured 21 Populus clones in the clonal nursery of the Packaging Corporation of America in Michigan. Degree of injury ranged from 0.5 to 81.09<. Clone 'Wisconsin 5' sustained the heaviest attack, followed by Imperial Carolina poplar. 'Wisconsin 5' was salvaged by changing the standard and accepting shorter cutting stock for outplanting.

Interspecific Interactions Between Orchelimum Nigripes And Orchelimum Volantum (Orthoptera: Tettigoniidae), Marianne Niedzlek Feaver

The Great Lakes Entomologist

[Excerpt] Interspecific interactions are relatively rare among coinhabiting Orthoptera. Most records are of overzealous males courting females not of their species or, for that matter, inanimate objects. Less frequent are reports of two signalling males interacting, yet these are of interest. Calling songs are used to distinguish species (Alexander 1956). The possibility then exists that the "interference" or, more correctly, the competition for broadcast space that occurs when two closely related species with similar songs interact, may have been influential in shaping aspects of song delivery or pattern.

State Records And Confirmations Of Odonata From Illinois And Missouri, T. E. Vogt, J. E. Mcpherson

The occurrence of several species of Odonata in Illinois and Missouri is reported for the first time including Telebasis byersi Westfall, Tachopteryx thoreyi (Hagen), Aeshna mutata Hagen, Celithemis fasciata Kirby, fodona deplanata (Rambur), and Dythemis fugax Hagen for Illinois; and Cordulegaster obliqua (Say), Gomphus quadricolor Walsh, Helocordulia uhleri (Selys), C. fasciata, and C. verna Pritchard for Missouri. Also, the presence of several species is confirmed including Archilestes grandis (Rambur), C. obliqua. Hagenius brevistylus Selys, and Anax longipes Hagen for Illinois; and Lestes eurinus Say, H. brevistylus, Stylogomphus albistylus (Hagen), Arigomphus villosipes (Selys), A. longipes, and L. deplanata for Missouri.

Systematics Of Anepeorus (Ephemeroptera: Heptageniidae), W. P. Mccafferty, A. V. Provonsha

The Great Lakes Entomologist

The enigmatic genus Anepeorus has a confused and complex taxonomic history that is discussed and clarified. The genus is redefined and described in the adult stage. Although laryae have been assigned to Anepeorus, these larvae cannot be shown at the present to be Atnepeorus. Two North American species are known from a total of 10 adult specimens . . -tnepeorus rusticus McDunnough and A. simplex (Walsh) are redescribed, and a neotype is designated for the latter species. Genitalic differences are diagnostic, but the penes may be found in different states of inflation and rotation that should not be interpreted as …

Environmental, Social, And Molecular Regulation Of Foraging Behavior In The Formosan Subterranean Termite, Arjun Khadka

LSU Doctoral Dissertations

Foraging is a critical activity in social insects, essential for resource acquisition and colony sustenance. In termites, this behavior is shaped by environmental, social, and genetic factors, yet the underlying regulatory mechanisms remain poorly understood. In this study, we examined how environmental food and moisture availability, and the age of termites affected foraging activities, along with the molecular regulation of foraging in the Formosan subterranean termite, Coptotermes formosanus, using a combination of behavioral assays, transcriptomics, and molecular biology approaches. First, we demonstrate that food and moisture deprivation (FMD) significantly affects foraging, with termites under deprivation conditions exhibiting increased foraging …
