Remote Sensing To Detect The Movement Of Wheat Curl Mites Through The Spatial Spread Of Virus Symptoms, And Identification Of Thrips As Predators Of Wheat Curl Mites, Abby R. Stilwell

Department of Entomology: Dissertations, Theses, and Student Research

The wheat curl mite (WCM), Aceria tosichella Keifer, transmits three viruses to winter wheat: wheat streak mosaic virus, High Plains virus, and Triticum mosaic virus. This virus complex causes yellowing of the foliage and stunting of plants. WCMs disperse by wind, and an increased understanding of mite movement and subsequent virus spread is necessary in determining the risk of serious virus infections in winter wheat. These risk parameters will help growers make better decisions regarding WCM management. The objectives of this study were to evaluate the capabilities of remote sensing to identify virus infected plants and to establish the potential …

Entomology Papers from Other Sources

The cycad aulacaspis scale, Aulacaspis yasumatsui Takagi, is currently found in China, Singapore, Hong Kong, Cayman Islands, Puerto Rico, U.S. Virgin Islands, Hawaii, and Florida (Germain and Hodges 2007). It was originally described from specimens collected on a Cycas sp., in Bangkok, Thailand, in 1972 (Takagi 1977). In recent years, finds have also been reported in California, Georgia, and Nevada (IUCN/SSC Cycad Specialist Group 2009). In 2006, severe outbreaks of cycad aulacaspis scale were reported in South Texas where sago palms, Cycas revoluta Thunb., adorn landscapes and are important ornamental plants for commercial nursery growers (Bográn et al. 2006).

Steinernema Diaprepesi (Nematoda: Steinernematidae): Its Occurrence In Western Mexico And Susceptibility Of Engorded Cattle Ticks Boophilus Microplus (Acari: Ixodidae), Jaime Molina-Ochoa, Khuong B. Nguyen, Martín González-Ramírez, Miguel Guadalupe Quintana-Moreno, Roberto Lezama-Gutiérrez, John E. Foster

Department of Entomology: Faculty Publications

Entomopathogenic nematodes (EPN) belong to the families Steinernematidae and Heterorhabditidae. They infect a wide range of insect hosts and are used to control numerous species of soil borne insect pests (Grewal 2002). We identified EPN genera based on the color of cadavers of the wax moth, Galleria mellonella L., in which Heterorhabditis and Steinernema, produce red and tan colors, respectively, according to Woodring & Kaya (1988). We obtained an isolate of an EPN from sandy loam soil with the Galleria technique (Bedding & Akhurst, 1975) from grasslands in the Campus Tecomán of the Universidad de Colima, and we designated it …

Hybridization In Diabrotica Barberi Smith And Lawrence And Diabrotica Longicornis (Say) (Coleoptera: Chrysomelidae): Biology, Behavior, Field Introgression, And A Reevaluation Of Taxonomic Status, Laura A. Campbell

Department of Entomology: Dissertations, Theses, and Student Research

Diabrotica barberi Smith and Lawrence and D. longicornis (Say) are currently recognized as closely related chrysomelid species. Morphological and genetic data support that the two species are sister taxa, and hybridization has been proposed to occur. The objectives of this work were to: 1) assess life history parameters of both taxa and hybrids, 2) compare mating behavior, pheromone response, and spermatophore transfer of both taxa and hybrids, and 3) examine genetic and morphological data for evidence of introgression. Using lab-reared individuals, fitness parameters and potential for population growth were assessed. D. barberi and D. longicornis differed in longevity and fecundity. …

Two Additional Invasive Scarabaeoid Beetles (Coleoptera: Scarabaeidae: Dynastinae) In Hawaii, Mary Liz Jameson, Darcy E. Oishi, Brett C. Ratcliffe, Grant T. Mcquate

University of Nebraska State Museum: Entomology Papers

Two species of dynastine scarab beetles are reported for the first time on the island of Hawaii: the Pasadena masked chafer, Cyclocephala pasadenae (Casey) (Scarabaeidae: Dynastinae: Cyclocephalini) from North America and Temnorhynchus retusus (Fabricius) (Scarabaeidae: Dynastinae: Pentodontini) from Africa. The Pasadena masked chafer is established on the island of Hawaii, is a recognized pest of turf grass, and is a concern for agriculture and native Hawaiian arthropod species. Temnorhynchus retusus is not known to be an agricultural pest, but its spread on the islands could pose a problem for Hawaiian native species. We provide an overview of each species, characteristics …

The larval stage is described for the first time and compared to that of other Lophodiplosis species. Photos of galls and illustrations of larvae are provided. Second and third instars of L. trifida are unusual among Cecidomyiidae for the lack of setae on most papillae.

Generic Reassignment Of Species In The Tribe Cephaloleiini Chapuis, 1875 (Coleoptera: Cassidinae), C. L. Staines

Insecta Mundi

Thirty-one species of Cephaloleiini are assigned to new genera, creating new combinations: 19 to Parimatidium Spaeth, 10 to Stilpnaspis Weise, and two to Demotispa Baly. Demotispa peruana membrata Uhmann, 1957 is raised to full species status. As the transfer of Cephaloleia limbatum Pic to Demotispa creates a homonymy, the species is renamed Demotispa pici nomen novum.

The Beetles Of St. Lucia, Lesser Antilles (Insecta: Coleoptera): Diversity And Distributions, Stewart B. Peck

Insecta Mundi

The published beetle fauna of the island of St. Lucia is summarized. It contains 135 genera, and 175 species in 25 families. Four species are accidentally introduced by human activities. Twenty three species are endemic (restricted) to the island. Twenty seven species on St. Lucia are shared only with other islands of the Lesser Antilles, and 22 species are widespread Antilles endemics. The remaining 56.6% of the fauna is otherwise mostly one which is widely distributed in the Antilles and the Neotropics. This suggests that it is mostly an immigrant fauna originating in the continental Neotropics. Undoubtedly, the actual numbers …

The Chemistry Of Lipid Signal Molecules In Insects, Sean M. Putnam

Department of Entomology: Dissertations, Theses, and Student Research

I report on the chemical identification of lipid signaling molecules in three species of insects and describe the chemical isolation of a bacterial product that inhibits eicosanoid biosynthesis. Chapter 2 reports that eicosanoids mediate nodulation reactions to bacterial infection in newly-emerged, but not forager honeybees. Cyclooxygenase and lipoxygenase inhibitors attenuate nodulation, which is reversed in the presence of arachidonic acid. Older adult honeybees do not produce bacterial-induced nodules, and they have fewer circulating hemocytes, from which I infer that foraging honeybees express a physiological trade-off between maintaining a biologically expensive hemocytic immune system and flight activity associated with foraging. Chapters …

Xyloryctes Hope, 1837 (Coleoptera: Scarabaeidae: Dynastinae: Oryctini) In The United States. Qui Es Et Ubi Fuisti Et Quo Vadis?, Brett C. Ratcliffe

Insecta Mundi

Two species of Xyloryctes occur in the United States: X. jamaicensis (Drury) and X. thestalus Bates. Identification and distribution of these species has long been confused but is reviewed and clarified here. Xyloryctes jamaicensis occurs only in the eastern half of the U.S. and not in the southwestern U.S. as previously thought, while X. thestalus occurs in Guatemala and southern Mexico northwards to the southwestern United States. This hypothesis is corroborated by biogeographical and host plant data. Three new synonyms are listed for X. thestalus: X. faunus Casey 1915, X. hebes Casey 1915, and X. thestalus borealis Endrödi. The …

A New Fossil Species Of Stag Beetle From Dominican Republic Amber, With Australasian Connections (Coleoptera: Lucanidae), Robert E. Woodruff

Insecta Mundi

The first New World amber member of the family Lucanidae is described from the Dominican Republic. Its age is presumed to be Miocene (20-30 million YBP). It is also the fourth known amber species, the second Miocene fossil species, the second fossil species in the subfamily Syndesinae, and the first species (fossil or extant) of Lucanidae from the entire Caribbean. It is especially interesting because it is a member of the Australasian genus Syndesus MacLeay. Other such disjunct Dominican amber insect fossils are also discussed.
