Genetic Research On Screwworm At Lincoln, Nebraska, Steven Skoda, Dennis Berkebile

Department of Entomology: Faculty Publications

The following interpretive summary refers to the 1st seminar given by Dr. Skoda at the IAEA-FAO 1st RCM Research Coordination Meeting for the CRP Coordinated Research Project, Jan-Feb 2002. Screwwoms, Cochliomyia hominivorax (Coquerel), are devastating pests of animals. They have been eradicated from mainland North America, with the exception of portions of eastern Panama, using the Sterile Insect Technique (SIT), a form of gtenetic control. Research at Lincoln, Nebraska has been in support of the international effort of SIT against screwworms. Successful cryopreservation of the screwworm has been achieved, is to be optimized, and will be a tool for preserving …

Series Scarabaeiformia Crowson 1960, Superfamily Scarabaeoidea Latreille 1802, Mary Liz Jameson, Brett C. Ratcliffe

University of Nebraska State Museum: Entomology Papers

The superfamily Scarabaeoidea is a large, diverse, cosmopolitan group of beetles. Scarabaeoids are adapted to most habitats, and they are fungivores, herbivores, necrophages, coprophages, saprophages, and some are carnivores. They are widely distributed, even living in the Arctic in animal burrows. Some scarabs exhibit parental care and sociality. Some are myrmecophilous, termitophilous, or ectoparasitic. Many possess extravagant horns, others are able to roll into a compact ball, and still others are highly armored for inquiline life. Some are agricultural pests that may destroy crops while others are used in the biological control of dung and dung flies. Scarabaeoids are popular …

Foreign Exploration For Scirtothrips Perseae Nakahara (Thysanoptera: Thripidae) And Associated Natural Enemies On Avocado (Persea Americana Miller), Mark S. Hoddle, Sueo Nakahara, Phil A. Phillips

USDA Systematic Entomology Laboratory

Scirtothrips perseae Nakahara was discovered attacking avocados in California,USA, in 1996. Host plant surveys in California indicated that S. perseae has a highly restricted host range with larvae being found only on avocados, while adults were collected from 11 different plant species. As part of a management program for this pest, a ‘‘classical’’ biological control program was initiated and foreign exploration was conducted to delineate the home range of S. perseae, to survey for associated natural enemies and inventory other species of phytophagous thrips on avocados grown in Mexico, Guatemala, Costa Rica, the Dominican Republic, Trinidad, and Brazil. Foreign …

Diagnoses, habitus photographs and drawings, and a key to the nine recognized species of Enaphalodes are provided.

Individual Variation In The Duration Of Territory Occupation By Males Of The Dragonfly Perithemis Tenera (Odonata: Libellulidae), Paul V. Switzer

Faculty Research & Creative Activity

In the dragonfly Perithemis tenera Say, males defend territories around oviposition sites and defense of a site is critical for reproductive success. This study first demonstrated that individual males varied consistently in how long they defended a particular territory within a day (their “tenure”) and in the quality of the sites they defended. I then investigated a number of factors that may have affected territory tenure and may have led to the observed variation among males. Territory occupations that ended “voluntarily” were significantly longer than those that ended because the male was evicted from his territory. For voluntary desertions, tenure …

Molecular Evidence For A Species Complex In The Genus Aphelinus (Hymenoptera: Aphelinidae), With Additional Data On Aphidiine Phylogeny (Hymenoptera: Braconidae), Yi Chen, Kristopher L Giles, Matthew H. Greenstone

Entomology Papers from Other Sources

Mitochondrial 16srDNAwas sequenced from nine different populations of Aphelinidae and 10 of aphidiinae. Sequence divergences between populations within a species are low, ranging from 0 to 0.38%. Divergences among species within the same genus range from 0 to 8.71%. Aphelinus asychis Walker has a sequence divergence from the other Aphelinus spp. of 8.71%, which is even higher than the divergences among the aphidiine genera Lysiphlebus, Aphidius and Diaeretiella. Our 16s rDNA phylogeny for aphidiines is concordant with a previously published NADH1 dehydrogenase phylogeny. Our analysis identiÞes a complex comprising A. albipodus (Hayat & Fatima), A. varipes (Foerster), and A. …

The Presence Of The Coffee Berry Borer, Hypothenemus Hampei, In Puerto Rico: Fact Or Fiction?, Fernando E. Vega, R. A. Franqui, Pablo Benavides

Entomology Papers from Other Sources

The coffee berry borer, Hypothenemus hampei Ferrari (Coleoptera: Scolytidae), is widely considered to be the most devastating pest of coffee. Endemic to Central Africa, the coffee berry borer can now be found in most coffee growing regions throughout the world (Le Pelley 1968). Annual losses caused by this insect have been estimated at over $500 million annually (P. Baker, CABI Bioscience, UK; personal communication). One of the most widely cited references on coffee berry borer presence in different countries is that of Le Pelley (1968), where more than 20 countries, including Puerto Rico, are listed as having the insect.

Beetle Diversity In An Eastern Cottonwood (Populus Deltoides Bartr.) Plantation And Adjacent Bottomland Hardwood Forest In Southeastern Arkansas, Michael D. Warriner, T. Evan Nebeker, Steven A. Tucker

Journal of the Arkansas Academy of Science

Within the Lower Mississippi Alluvial Valley (LMAV),some lands cleared of bottomland hardwood forests have the potential to return to forest as a result of private sector and government interests in Populus cultivation. Specifically, monoculture plantings of eastern cottonwood (Populus deltoides Bartr.) represent an important component of many recent afforestation efforts in the region. The impact establishment of such monocultures will have on native insect communities in the LMAV is relatively unknown. To evaluate this, beetle (Coleoptera) diversity, abundance, and functional distribution were examined within an intensively managed eastern cottonwood plantation and nearby bottomland hardwood forest in southeastern Arkansas. Beetles were …

One New Species And One New Combination In Netechma Razowski (Lepidoptera: Tortricidae: Euliini), John W. Brown, David Adamski

USDA Systematic Entomology Laboratory

Netechma similis, new species, from Costa Rica, is described and illustrated, and Netechma caesiata (Clarke), new combination, from Venezuela, is redescribed and illustrated. Netechma Razowski belongs to a group of genera in Euliini characterized by one or more sparganothine-like features of the male genitalia, including a spiny transtilla; a long, slender, hooklike uncus; and densely scaled socii. Adults of the two treated species are superficially most similar to species of Icteralaria Razowski, with a forewing that features a broad, dark, medial band on a pale yellow ground color.

Effects Of Fire Frequency And The Red Imported Fire Ant On Native Insects In A Louisiana Longleaf Pine Savanna, Deanna M. Colby

LSU Doctoral Dissertations

Ants and ground beetles were collected in pitfall traps from a longleaf pine savanna in the early stages of restoration. Insect abundance and species richness were compared among four treatment combinations of two fire frequencies and presence and absence of an exotic ant, Solenopsis invicta, the red imported fire ant. Amdro® was used to suppress S. invicta. Fire treatments consisted of a single fire in a two year period or two fires in a two year period, one applied each year. Fires were applied late in the growing season both years. Ten of the 28 ground beetle species …

Screening And Characterization Of Pathogenic Fungi For Possible Control Of Coptotermes Formosanus, Jianzhong Sun

LSU Doctoral Dissertations

Coptotermes formosanus was used as “bait” to isolate pathogenic fungi from soil. Fifteen pathogenic fungal isolates were obtained, all either Metarhizium anisopliae (six isolates) or Beauveria bassiana (nine isolates). There were no differences in numbers of fungal isolates from the three sampling locations. However, significantly more isolates were found in woodlands (eleven) than in pastures (four). Median lethal doses (LD50s) of these fungal species to C. formosanus were interspersed, indicating that fungal isolates rather than species had the greatest effect on virulence. In vitro growth characteristics were significantly correlated with virulence against termites, suggesting that fungal virulence might be predicted …

Development Of Diagnostic Tools For Detecting Expression Of Resistance-Associated Esterases In The Tobacco Budworm, Heliothis Virescens (F.), Huazhang Huang

LSU Doctoral Dissertations

Esterase-based metabolic resistance was studied using biochemical and biological assays with organophosphate (OP)- and pyrethroid (PYR)- resistant tobacco budworms, Heliothis virescens. In biochemical assays, results suggest that: (1) esterase activities toward all substrates used were enhanced in both resistant strains compared with the susceptible strain, suggesting that esterases were involved in resistance; (2) esterase profiles differed depending on the strain and substrate used, and these differences were visualized by using native polyacrylamide gel electrophoresis; 3) esterase activities toward some pyrethroid substrates were significantly higher (P ≤ 0.01) in the PYR-R strain than those in the OP-R strain. These results suggest …

Organophosphorous Insecticide Contamination In Streams: Insects As Bioindicators, Brian M. Andersen

Dissertations and Theses @ UNI

Organophosphorous (OP) insecticides are widely used around the world to control pests. These insecticides can enter streams and rivers and impact nontarget aquatic organisms by inhibiting acetylcholinesterase (ACE), a nervous system enzyme necessary for normal behavior and survival. However, these contamination events are usually brief and often missed by chemical analyses attempting to detect OP insecticides. Although ACE activity has been used as a bioindicator of OP insecticide exposure in humans and wildlife for many years, few studies have investigated using aquatic insect ACE activity as a potential bioindicator of OP insecticide contamination in streams. This study used the mayfly …
