New State And Island Records Of Coccinellidae (Coleoptera) In Hawai‘I, Usa, Louis S. Hesler, William D. Perreira, Dana Anne Yee, Joshua H.S. Silva

Insecta Mundi

Three new records of Coccinellidae (Coleoptera) are recorded within the state of Hawai‘i, USA. Diomus roseicollis (Mulsant, 1853) is newly recorded from the state based on four specimens collected on the island of O‘ahu. Cycloneda sanguinea sanguinea (Linnaeus, 1763) and Brumoides suturalis (Fabricius, 1789), both already established in the state, are newly recorded from the island of Hawai‘i. Additional sampling is recommended to determine the distribution of D. roseicollis within the island of O‘ahu. Further surveys are warranted to determine particular habitats and prey for D. roseicollis, C. sanguinea sanguinea, and B. suturalis in …

A New Species Of Cymatodera Gray (Coleoptera: Cleridae: Tillinae) From Baja California, Mexico, Jacques Rifkind Sep 2020

A New Species Of Cymatodera Gray (Coleoptera: Cleridae: Tillinae) From Baja California, Mexico, Jacques Rifkind

Insecta Mundi

The Cymatodera Gray fauna of Baja California (the Mexican states of Baja California and Baja California Sur) comprises fifteen species, of which six (C. minacis Barr, C. intermedia Barr, C. fascifera LeConte, C. santarosae Schaeffer, C. cephalica Schaeffer, and C. purpuricollis Horn) are endemic to the peninsula. Three of these endem­ics (C. intermedia, C. cephalica, and C. purpuricollis) are apterous. The remaining nine species are more broadly distributed, with ranges that extend north into the U.S. border states. This paper describes a new species of fully winged, endemic Baja Cymatodera.

Insecta Mundi

Many species of plants and a few species of animals are believed to have resulted from hybridization of parental species, and the ability of species to occasionally hybridize in captivity and in nature is even more widespread. In the present study, we describe a hybridization experiment conducted in the laboratory between the sexually dimorphic Automeris io (Fabricius), a widespread, variable species ranging from Canada to Costa Rica, and its congener A. louisiana (Ferguson and Brou), a more local, sexually monomorphic species (Lepidoptera: Saturniidae). The A. louisiana populations occur in a highly specialized habitat—the coastal marshland along the Gulf of Mexico …

Systematic Status Of The Chilean Genus Carlota Arias-Bohart, 2014 (Coleoptera: Elateridae: Agrypninae: Agrypnini), Elizabeth T. Arias-Bohart Sep 2020

Systematic Status Of The Chilean Genus Carlota Arias-Bohart, 2014 (Coleoptera: Elateridae: Agrypninae: Agrypnini), Elizabeth T. Arias-Bohart

Insecta Mundi

The click beetle genus Carlota Arias-Bohart (Coleoptera: Elateridae: Agrypninae: Agrypnini) was considered as a junior synonym of Candanius Hayek recently. However, there are deep morphological differences between these genera which justify the validity of Carlota. The morphology of this genus was re-examined in detail and based on the short and shallow antennal grooves, strongly serrate antennae from antennomeres 3 through 10, subquadrate pronotum with four distinct subcircular depressions, and straight prosternal process not bent dorsally, I resurrect the genus Carlota from synonymy.

Suitability Of Native Milkweed (Asclepias) Species Versus Cultivars For Supporting Monarch Butterflies And Bees In Urban Gardens, Adam M. Baker, Carl T. Redmond, Stephen B. Malcolm, Daniel A. Potter

Entomology Faculty Publications

Public interest in ecological landscaping and gardening is fueling a robust market for native plants. Most plants available to consumers through the horticulture trade are cultivated forms that have been selected for modified flowers or foliage, compactness, or other ornamental characteristics. Depending on their traits, some native plant cultivars seem to support pollinators, specialist insect folivores, and insect-based vertebrate food webs as effectively as native plant species, whereas others do not. There is particular need for information on whether native cultivars can be as effective as true or “wild-type” native species for supporting specialist native insects of conservation concern.

Black soldier fly frass fertilizer (BSFFF) is increasingly gaining momentum worldwide as organic fertilizer. However, research on its performance on crop production remains largely unknown. Here, we evaluate the comparative performance of BSFFF and commercial organic fertilizer (SAFI) on maize (H513) production. Both fertilizers were applied at the rates of 0, 2.5, 5, and 7.5 t ha-1, and 0, 30, 60, and 100 kg nitrogen (N) ha-1. Mineral fertilizer (urea) was also applied at 0, 30, 60 and 100 kg N ha-1 to establish the N fertilizer equivalence (NFE) of the organic fertilizers. Maize grown in plots treated with BSFFF …

All Peer-Reviewed Publications

Edible insects reared under suitable climatic conditions are an efficient and ecological food source. However, most of the insects come from wild collection and not from farms (FAO, 2013). To establish insects as part of a sustainable food environment, collectors, farmers or small entrepreneurs need to be transformed into mini-livestock farmers, but people who eat or collect insects do not necessarily want to rear them. This paper presents four case studies from Kenya, Madagascar, Myanmar and Thailand, which are in different stages of sector development to show pathways for establishing insect rearing, and the associated economic, resource/ecological and social challenges …

Permethrin Residual Activity Against Ambrosia Beetle (Coleoptera: Curculionidae: Scolytinae) Attacks Following Field Aging And Simulated Rainfall Weathering, Matthew S. Brown, Karla M. Addesso, Fulya Baysal-Gurel, Nadeer N. Youssef, Jason B. Oliver Aug 2020

Permethrin Residual Activity Against Ambrosia Beetle (Coleoptera: Curculionidae: Scolytinae) Attacks Following Field Aging And Simulated Rainfall Weathering, Matthew S. Brown, Karla M. Addesso, Fulya Baysal-Gurel, Nadeer N. Youssef, Jason B. Oliver

Agricultural and Environmental Sciences Faculty Research

Adult ambrosia beetles (Coleoptera: Curculionidae: Scolytinae) bore into ornamental nursery trees resulting in trunk vascular tissue damage, which can potentially kill trees. Ambrosia beetle exposure to surface-applied insecticides is minimal after internal trunk galleries are formed, so effective management requires insecticide treatments to be applied near the time of infestation or to have residual activity on the bark. Tree trunk sections (bolts) were used to determine the effect of field aging or irrigation (i.e., simulated rainfall weathering) on permethrin residual activity against ambrosia beetles. In all experiments, 30-cm-long bolts from Liriodendron tulipifera L. (Magnoliales: Magnoliaceae) were hollowed and filled with …

Entomology Faculty Publications

Insects experience a diversity of subtoxic and/or toxic xenobiotics through exposure to pesticides and, in the case of herbivorous insects, through plant defensive compounds in their diets. Many insects are also concurrently exposed to antioxidants in their diets. The impact of dietary antioxidants on the toxicity of xenobiotics in insects is not well understood, in part due to the challenge of developing appropriate systems in which doses and exposure times (of both the antioxidants and the xenobiotics) can be controlled and outcomes can be easily measured. However, in Drosophila melanogaster, a well-established insect model system, both dietary factors and …

Socio-Economic And Environmental Implications Of Replacing Conventional Poultry Feed With Insect-Based Feed In Kenya, Zewdu Abro, Menale Kassie, Chrysantus Tanga, Dennis Beesigamukama, Gracious Diiro Aug 2020

Socio-Economic And Environmental Implications Of Replacing Conventional Poultry Feed With Insect-Based Feed In Kenya, Zewdu Abro, Menale Kassie, Chrysantus Tanga, Dennis Beesigamukama, Gracious Diiro

All Peer-Reviewed Publications

The growing scarcity of resources for feed production and environmental concerns highlight the unsustainability of conventional feed sources. Insect farming is considered as an alternative feed due to its low land and water requirements, its low ecological footprint, and circular economy contribution by converting biowaste into high-quality feed ingredients. While there is growing research on the technical feasibility and nutritional performance of insect-based feed, its potential beneifts are not quanitified. Using experimental and secondary data, we assess the potential socio-economic benefits of black soldier fly larvae meal (BSFLM) to the Kenyan poultry sector. We find that replacing 5–50% of the …

Nonnative Insect Invasions In Natural Ecosystems: Impacts, Policy, And Evaluation Of Drivers Using Underutilized Biocontrol Datasets, Ashley N. Schulz Aug 2020

Nonnative Insect Invasions In Natural Ecosystems: Impacts, Policy, And Evaluation Of Drivers Using Underutilized Biocontrol Datasets, Ashley N. Schulz

Student Theses and Dissertations

The fundamental goal in invasion ecology is to understand what drives the success of nonnative species. To assess mechanisms of invasion, invasion ecologists traditionally study populations of nonnative species that have already established and spread within an environment. A less common method is to use data from classical biocontrol agents, which are also nonnative and have variable impacts with respect to efficacy and non-target effects. Further elucidation of mechanisms of invasion can help researchers develop better methods for detection, prevention, and control of nonnative species. To make progress in the battle against nonnative species, focus should be placed on both …
