Sap beetles are typically considered a secondary pest of corn and overripe fruits and vegetables. They are broadly identified by their small and ovular bodies and club-shaped antennae. Adult sap beetles often feed on corn silk, pollen, and tassels. Larvae feed on kernels inside the husk. This fact sheet reviews how to identify sap beetles and their hosts and damage. It also provides ideas on how to monitor for sap beetles and outlines the options for managing them.

Stink Bug (Hemiptera: Heteroptera: Pentatomidae) Ecology In Nebraska Agroecosystems, Blessing Ademokoya
Department of Entomology: Dissertations, Theses, and Student Research
Stink bugs (Hemiptera: Heteroptera: Pentatomidae) have gained considerable attention in Nebraska in the last decade due to increasing densities of native stink bug and spread of invasive species in the Midwest. Little is known about stink bug dynamics in Nebraska cropping systems. Based on data from a recent field survey, specimens at the University of Nebraska State Museum and the diagnostic lab of the Entomology Department at the University of Nebraska Lincoln, as well as published literature, we present a checklist of 72 species and subspecies of Pentatomidae (55 Pentatominae, 13 Asopinae, 3 Podopinae and 1 Edessinae) that occur in …

Cardenolide, Potassium, And Pyrethroid Insecticide Combinations Reduce Growth And Survival Of Monarch Butterfly Caterpillars (Lepidoptera: Nymphalidae), Annie J. Krueger, Emily A. Robinson, Thomas J. Weissling, Ana M. Vélez, Troy D. Anderson
Department of Entomology: Faculty Publications
The monarch butterfly, Danaus plexippus L., has evolved to be insensitive to milkweed cardenolides via genetic modifications of Na+/K+-ATPase. There is concern for insecticide exposures near agriculture, with little information on monarch caterpillar toxicology. It is unclear how cardenolide insensitivity may affect the sensitivity of monarch caterpillars to pyrethroid insecticides. Additionally, potassium fertilizers may affect monarch caterpillar physiology and cardenolide sequestration. Here, we investigated the growth, survival, and development of caterpillars exposed to the cardenolide ouabain, bifenthrin, and potassium chloride (KCl) alone and in combination. Caterpillars were either exposed to (1) ouabain from third- to fifth-instar …
Evidence Of Western Corn Rootworm (Diabrotica Virgifera Virgifera Leconte) Field-Evolved Resistance To Cry3bb1 + Cry34/35ab1 Maize In Nebraska, Jordan Reinders, Emily E. Reinders, Emily Robinson, Brian W. French, Lance J. Meinke
Evidence Of Western Corn Rootworm (Diabrotica Virgifera Virgifera Leconte) Field-Evolved Resistance To Cry3bb1 + Cry34/35ab1 Maize In Nebraska, Jordan Reinders, Emily E. Reinders, Emily Robinson, Brian W. French, Lance J. Meinke
Department of Entomology: Faculty Publications
BACKGROUND: Western corn rootworm (WCR; Diabrotica virgifera virgifera) field-evolved resistance to transgenic maize expressing the Cry3Bb1 protein derived from Bacillus thuringiensis (Bt) has been confirmed across the United States Corn Belt. Although use of pyramided hybrids expressing Cry3Bb1 + Cry34/35Ab1 has increased in recent years to mitigate existing WCR Bt resistance, susceptibility of Nebraska WCR populations to this rootworm–Bt pyramid has not been assessed. Plant-based bioassays were used to characterize the susceptibility of WCR populations to Cry3Bb1 and Cry3Bb1 + Cry34/35Ab1 maize. Populations were collected from areas of northeastern Nebraska with a history of planting Bt maize that expressed Cry3Bb1 …
American Burying Beetle, Plant Richness, And Soil Property Responses To Collapse Of Juniperus Virginiana Woodlands With Fire, Alison Ludwig
American Burying Beetle, Plant Richness, And Soil Property Responses To Collapse Of Juniperus Virginiana Woodlands With Fire, Alison Ludwig
Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research
Grasslands are declining in the Great Plains due to land use changes, woody plant encroachment, and loss of historic fire cycles. Prescribed burn associations have utilized prescribed fire to collapse invading woodlands and allow the restoration of grasslands. This fire is considered “extreme” because it is capable of changing the structure and function of an ecosystem. Our study site is the Loess Canyons Experimental Landscape, a long-term, ecoregion-scale experiment to apply prescribed fire across the region to restore grasslands. The Nebraska Natural Legacy Project established the Loess Canyons ecoregion as a Biologically-Unique Landscape in 2005 with the state’s wildlife action …

In Utah high tunnel production, there are various caterpillar pests (larvae of moth and butterfly species) that cause economic damage to crops. Common caterpillar pest species found in Utah include hornworms, tomato fruit worms, imported cabbage worms, diamondback moths, cabbage loopers, armyworms, and cutworms. Various weed species growing inside or outside high tunnels can attract and harbor caterpillar pests. Managing caterpillar pests in high tunnels involves various mechanical, chemical, biological, and cultural control practices.

Hay una serie de insectos con el hábito alimenticio de perforar y succionar que pueden causar deformidad y lesiones del tipo cara de gato en los frutales de pepita y hueso, como la chinche ligus, la chinche hedionda y la chinche del boxelder. La lesión cara de gato es causada cuando la chinche se alimenta agujerando los botones florales y la fruta. El resultado son depresiones, deformidades y cicatrices desagradables en la fruta. El nombre “cara de gato” proviene de la forma distorsionada de la fruta que se asemeja a las mejillas fruncidas de un gato. Además de los insectos …
How Weeds Affect Insects In Mango Cultivation Of South Florida, Blaire Kleiman
How Weeds Affect Insects In Mango Cultivation Of South Florida, Blaire Kleiman
FIU Electronic Theses and Dissertations
The use of weeds as insectary plants is an emerging management tactic by agroecologists and entomologists to sustain beneficial insect species. Fallow lands have always been used by insects and are an important part of their diet in fragmented ecosystems. Weeds provide floral resources to beneficial insects such as pollinators, parasitoids, and predators and resources to keep them within a field in between crop flowering. Using weeds as a tool in tropical fruit production reliant on pollination like Mango (Mangifera indica) allows farmers to reduce herbicide use, increases the biodiversity of both plants and insects, and increases pollination of crops …

Investigating The Role Of Spiders In Integrated Pest Management For Biological Control Of Nebraska Crop Pests, Samantha Daniel
Department of Entomology: Dissertations, Theses, and Student Research
As generalist predators, spiders are capable of fulfilling a wide variety of ecological niches allowing them to intercept and prey upon an array of insect species. This characteristic could be particularly advantageous within agricultural ecosystems. This project sought to reveal the composition and abundance of spider communities within cornfields in western Nebraska and the impact of agronomic practices on those communities as well as determine the potential for spider predation upon two key pests of corn. Spiders were collected from eight corn fields from May to August 2017 and four corn fields from May to August 2018. Additionally, the populations …

Including farmers, growers, and ranchers (hereinafter referred to as producers) as active participants in the development of knowledge, through extension and on-farm research programs, is an effective method of agricultural technology and innovation transfer. The emerging interest in understanding agricultural systems’ complexity has fostered collaborations between producers and land grant universities, particularly across graduate programs focused on applied research. While the concept of on-farm research is not new, the scale and impact of on-farm studies conducted by researchers in partnership with producers are expanding (Kyveryga, 2019). Can master’s and Ph.D. research projects be conducted at the farm scale and generate …

Soybean Gall Midge In Nebraska, Anthony J. Mcmechan, Thomas Hunt, Robert J. Wright
Eastern Nebraska Research, Extension and Education Center
Soybean gall midge (Resseliella maxima Gagné) was described in 2019 as a new insect species in Nebraska, due to observations of widespread early season injury in eastern Nebraska, eastern South Dakota, western Iowa, and southwest Minnesota soybean fields (Gagné et al., 2019). Since its discovery, soybean gall midge has been causing significant injury and yield losses in soybean in eastern Nebraska. Although only recently identified, soybean gall midge is not likely new to the north- central region of the U.S. In 2011, orange larvae were documented in some isolated fields in northeast Nebraska that had received hail damage during the …
