Advancing Butterfly Systematics Through Genomic Analysis, Jing Zhang, Qian Cong, Jinhui Shen, Leina Song, Nick V. Grishin 2025 University of Texas Southwestern Medical Center

Advancing Butterfly Systematics Through Genomic Analysis, Jing Zhang, Qian Cong, Jinhui Shen, Leina Song, Nick V. Grishin

The Taxonomic Report of the International Lepidoptera Survey

Within the framework of an ongoing comparative genomic study of global butterfly diversity, we construct phylogenetic trees combining all protein-coding genes assembled from the whole genome shotgun data. When viewed in the context of current taxonomy and phenotypic knowledge, the genome-wide phylogeny points to further advances in butterfly systematics, which are presented here. We assign major clades with comparable levels of genetic divergence to the same taxonomic rank and apply criteria involving relative population divergence and gene flow to define species boundaries. As a result, one genus, 13 subgenera, 62 species, and five subspecies are proposed as new (type species …


Ammonia Regulation In Aedes Taeniorhynchus, A Salt-Water Mosquito, Joseph Edmonds 2025 University of San Diego

Ammonia Regulation In Aedes Taeniorhynchus, A Salt-Water Mosquito, Joseph Edmonds

Undergraduate Honors Theses

The salt tolerant mosquito species Aedes taeniorhynchus has been observed in high salinity and ammonia conditions. Previous studies indicate Na+/K+ ATPase (NKA), the proton pump vacuolar-type H+ ATPase (VHA) and sodium-dependent cation-chloride cotransporters (NKCC’s) in sodium secretion in larval Aedes taeniorhynchus. However ammonia transporter such as Rh-protein, Amt1, and Amt2 have only been characterized in Aedes taeniorhynchus’s fresh water relative Aedes aegypti. Our research exhibits the expression of these transporters in A.taeniorhynchus using immunohistochemistry techniques. Evidence of VHA and NKA function in ammonia transport was characterized in vivo using drug antagonists in varying saline and ammonia concentrations. Ammonia flux rates …


Potential Economic Impact Of Grapevine Phylloxera (Hemiptera: Phylloxeridae) On Western Australian Winegrapes, David C. Cook, Andrew S. Taylor, Peter S. Gardiner, Rodrigo Pires, Hamish L R McKirdy, Karen W. Holmes, Helen Spafford 2025 Department of Primary Industries and Regional Development, Western Australia

Potential Economic Impact Of Grapevine Phylloxera (Hemiptera: Phylloxeridae) On Western Australian Winegrapes, David C. Cook, Andrew S. Taylor, Peter S. Gardiner, Rodrigo Pires, Hamish L R Mckirdy, Karen W. Holmes, Helen Spafford

Viticulture Research Articles

Grapevine phylloxera Daktulosphaira vitifoliae Fitch (Hemiptera: Phylloxeridae) has been present in Australia for almost 150 years but has not spread to south-west Western Australia, in part due to the relative isolation of the region. Recent improvements in tourist access, with interstate flights now arriving at Busselton Margaret River Airport, raise concerns about potential phylloxera introductions via wine tourism. In this paper, we simulate the potential economic impact on the Western Australian winegrape industry following a hypothetical arrival event in the Margaret River wine region. We use soil texture maps to assess the suitability of winegrape-growing areas to phylloxera establishment and …

Description And Biology Of Bumblebees (Hymenoptera: Apidae) In Michigan, Robert W. Husband, Roland L. Fischer, T. Wayne Porter

The Great Lakes Entomologist

The distribution of Michigan Bombinae was first studied by Milliron (1939). Records of Michigan bumblebees were included in Cockerell (1916) Franklin (1912). Lutz and Cockerell (1920). and Mitchell (1962). Other major studies in the Great Lakes Region were Chandler (1950) for Indiana, Medler and Carney (1%3) for Wisconsin, Husband (1966) for Michigan, Macfarlane (1974) for Ontario, LaBerge and Webb (1962) for Nebraska, Stevens (1948) for North Dakota, Frison (1926) for Illinois, and Neave (1933) for Manitoba. The purpose of this paper is to add to the information presented by Milliron (1939) and to complement the works by Chandler, Medler and …


The Biology Of The White Pine Sawfly, Neodiprion Pinetum (Hymenoptera: Diprionidae) In Wisconsin, Aunu Rauf, D. M. Benjamin 2025 University of Wisconsin

The Biology Of The White Pine Sawfly, Neodiprion Pinetum (Hymenoptera: Diprionidae) In Wisconsin, Aunu Rauf, D. M. Benjamin

The Great Lakes Entomologist

The white pine sawfly, Neodiprion pirletunl. is monophagous on eastern white pine, Pinus strobus, throughout its range in eastern North America. Localized outbreaks occur frequently, and small areas of white pine may be killed. The high population upsurge in Crawford County. Wisconsin, in 1978 was mitigated by the eulophid egg parasite, Closterocerus cinctipennis, when a mean 90.1 t 4.870 parasitization occurred. Larval parasitization in the Grant County infestation averaged 45.05%. and involved the ichneumonid, Olesicampe lophyri, the perilampid Perilamplts l~yalirllcs, and the tachinid Spathimeigenia erecta.

The Great Lakes Entomologist

PETE (Predictive Extension Timing Estimator) model output for Grapholitha molesta (Busck) was within ca. 30 ? 46 degree-days or 1.4 2 2 days of predicting 50% adult moth activity as measured by pheromone trap catches in the spring and first summer generation in both Michigan apple and California Peach orchards. In subsequent summer generations. model output was less reliable.


Instar Head Widths, Individual Biomass, And Development Rate Of Forest Tent Caterpillar, Malacosoma Disstria (Lepidoptera: Lasiocampidae), At Two Densities In The Laboratory, Jocelyn M. Muggli, William E. Miller 2025 USDA Forest Service

Instar Head Widths, Individual Biomass, And Development Rate Of Forest Tent Caterpillar, Malacosoma Disstria (Lepidoptera: Lasiocampidae), At Two Densities In The Laboratory, Jocelyn M. Muggli, William E. Miller

The Great Lakes Entomologist

Two colonies of forest tent caterpillar were reared at different densities on trembling aspen foliage in an environment chamber programmed for natural temperatures. Based on direct observation of molting, both colonies underwent five instars which overlapped negligibly in head width. Instar head widths were relatively stable between colonies, but individual biomass was sensitive to the different densities. Instars 3-5 in the less dense colony were heavier than those of the more dense by factors of 1.3-1.9. Development to 10-20% of larvae spinning cocoons took 40 days in the less dense colony and 45 days in the more dense. Size of …

Localized Field Migration Of The Adult Alfalfa Weevil, Clover Leaf Weevil, And Clover Root Curculio (Coleoptera: Curculionidae), And Its Implication For A Fall Pest Management Program, Robert D. Pausch, Stephen J. Roberts, Robert J. Barney, Edward J. Armbrust 2025 Illinois Natural History Survey

Localized Field Migration Of The Adult Alfalfa Weevil, Clover Leaf Weevil, And Clover Root Curculio (Coleoptera: Curculionidae), And Its Implication For A Fall Pest Management Program, Robert D. Pausch, Stephen J. Roberts, Robert J. Barney, Edward J. Armbrust

The Great Lakes Entomologist

The migration of the alfalfa weevil, clover leaf weevil and clover root curculio from aestivation sites into adjacent alfalfa fields was monitored with several different trapping systems. It was found that the initial dispersal back into alfalfa fields following aestivation was a slow gradual movement across the soil surface with flight occurring only after the insects had been in the alfalfa for several days.


Observations On The Biology Of The Slender Seedcorn Beetle, Clivina Impressifrons (Coleoptera: Carabidae), Robert D. Pausch, Lois M. Pausch 2025 Illinois Natural History Survey

Observations On The Biology Of The Slender Seedcorn Beetle, Clivina Impressifrons (Coleoptera: Carabidae), Robert D. Pausch, Lois M. Pausch

The Great Lakes Entomologist

The slender seedcorn beetle, Clirina impressijirons, is known to attack germinating corn seed, but field and laboratory studies of its life history indicate it may sometimes play a beneficial role. Feeding studies show that adults and larvae are primarily carnivorous but will feed on corn seed when their primary food is absent or in short supply. Certain behavioral aspects indicate that populations of this beetle might be attracted to selected agricultural areas where adults and larvae could serve as predators of soil pests of corn. Much of the activity of these beetles is governed by temperature. with low temperatures below …
