Theclinae Of Rondonia, Brazil: Gigantorubra And Angulopis, With Descriptions Of New Species (Lepidoptera: Lycaenidae), George T. Austin, Kurt Johnson

Insecta Mundi

The species of Gigantorubra and Angulopis encountered in the Cacaulandia area of central Rondonia, Brazil, are reviewed. These include species (all new) of Gigantorubra (G. microserrata, G. divergens, G. quadramacula, G. ampla, G. fuscafascia, G. silva, G. rondonia, G. obscura, G. perplexa, G. purpura) and one new species of Angulopis (A. tenuis). Thecla sangola Hewitson (1868) is recognized as having priority over Thecla autoclea Hewitson (1863-1878 [1877]), new synonym. Rondonia continues to appear as a center of thecline endemism and to provide abundant examples of sibling species diversity.

Riparian Refugia In Agroforestry Systems, Mary Ellen Dix, Erol Akkuzu, Ned B. Klopfenstein, Jianwei Zhang, Mee-Sook Kim, John E. Foster

Department of Entomology: Faculty Publications

In the last 200 years, cultivation, grazing, and other activities initiated by humans have destroyed more than 80 percent of the strips of vegetation along North American and European streams and other bodies of water (Decamps and Naiman 1989; Petts et al. 1989). This disappearance of the riparian zones is continuing with little concern for ecological consequences. At the same time, riparian buffer strips are being promoted as a preferred management practice in the United States, especially in the Great Plains, to protect water resources from soil and chemical pollution (Schoeneberger 1994; Schoeneberger et al. 1995; Schultz et al. 1995a; …

Insect Pests And Arthropod Predators Associated With Tree-Turf Landscapes, Mary Ellen Dix, Frederick P. Baxendale

Department of Entomology: Faculty Publications

Sweep-nets and pitfall traps were used to examine the distribution and dynamics of predominant predators and pests in turfgrass foliage in parks, golf courses and suburban/rural landscapes in 1991 and 1992. Araneae, Formicidae, and Coccinellidae were the most abundant predators in the sweeps, while Araneae, Formicidae, and) Carabidae were the most abundant predators in the pitfall traps. In both years, Araneae comprised over 60% of the total predators in the sweep samples. Formicidae (>70%) and Araneae (13-19%) were the most abundant arthropod predators in the pitfall samples. Cicadellidae, Chrysomelidae, and Orthoptera accounted for over 96% of the prey in …

Revision Of The Anastrepha Benjamini Species Group And The A. Pallidipennis Complex (Diptera: Tephritidae), Allen L. Norrbom

Insecta Mundi

The shape of the facial carina in Anastrepha is discussed. Although taxonomically useful, the protrudent form probably occurs by convergence in different species groups. Two species groups in which the carina is usually produced are revised. The benjamini species group includes: benjamini Lima (from southeastern Brazil), gigantea Stone (from Panama), magna, n. sp. (from Colombia and Venezuela), and superflua Stone (from Panama). Host data for this group are limited to only one record of benjamini from a species of Pouteria (Sapotaceae). The pallidipennis complex, which is included in the pseudoparallela species group, is recognized to include: amnis Stone (from …

A Revision Of The Sclerocoelus Galapagensis Group (Diptera: Sphaeroceridae: Limosininae), S. A. Marshall

The south Atlantic species Sclerocoelus subbrevipennis (Frey), new combination, is redescribed as a member of the S. galapagensis group, and is considered the sister species to the rest of the species group. A key to species, character matrix, and cladogram are provided.

A New U.S. Record For A Secondary Fruit Infester, Neosilba Batesi (Curran) (Diptera: Lonchaeidae), Kurt Ahlmark, Gary J. Steck

Insecta Mundi

A lonchaeid fly, Neosilba batesi, first described by Curran in 1932 from Guatemala, is here reported in Florida as of September 1994, a new U.S. record. Five larvae found infesting avocado fruit were reared to adults. The authors first identified the adults and our initial determination was confirmed by Dr. Al Norrbom of the Systematic Entomology Laboratory, USDA, Washington, D.C. A number of other specimens were subsequently collected and are recorded here as well. The species is probably a secondary invader of fruit, following initial attack by Anastrepha fruit flies, as observed in several other lonchaeid species (Curran, 1932; …

The Nearctic Species Of Oetophorus (Hymenoptera, Ichneumonidae, Ctenopelmatinae), John R. Barron

The name Oetophorus stretchii (Cresson) is placed in synonmy with the name Oetophorus pleuralis (Cresson). Relationships of the genus with others in the tribe Perilissini nnd relationships of the species included in the genus are briefly discussed.

Book Review: Biologie Des Coleopteres Chrysomelides By Pierre Jolivetj, R. H. Arnett Jr.

Insecta Mundi

The main biological aspects of this economically important group of beetles, the Chrysomelidae, are summarized in this new work by the internationally known author, Dr. Pierre Jolivet. Around 37,000 species are now described and more remain to be named. The size and diversity of the family are less than those of the weevils (Curculionidae), but probably there will be a total of 40 to 50 thousand species once the canopy fauna is better known. For instance, we still know nothing about the biology and the host plants of the Madagascaran leaf beetles and surely many more species from that region …

Effects Of Shelterbelts On The Aerial Distribution Of Insect Pests In Muskmelon, Mary Ellen Dix, Laurie Hodges, James R. Brandle, Robert J. Wright, Mark O. Harrell

Department of Entomology: Faculty Publications

Sticky traps were used to measure how tree shelterbelts influence the abundance of crop insect pests and beneficial arthropods in muskmelon (Cucumis melo L.) plots in eastern Nebraska. Abundance of striped cucumber beetles {Acalymma vittatum Fabricius (Coleoptera: Chrysomelidae)} , southern corn rootworms {Diabrotica undecimpunctata howardi Barber (Coleoptera: Chrysomelidae)}, and northern corn rootworms {D. barberi Smith & Lawrence (Coleoptera: Chrysomelidae)} was similar in exposed and sheltered plots. Western corn rootworms {D. virgifera LeConte (Coleoptera: Chrysomelidae)} were significantly more abundant in exposed plots. More lady beetles (Coleoptera: Coccinellidae) and ichneumonid wasps (Hymenoptera: Ichneumonidae) were caught on traps …

Effects Of Alachlor On An Algal Community From A Midwestern Agricultural Stream, Rebecca Spawn, Kyle D. Hoagland, Blair Siegfried

Department of Entomology: Faculty Publications

The effects of a single pulse, 21-d exposure of the commonly used herbicide alachlor (2-chloro-2′, 6′-diethyl-N-methoxymethyl acetanilide) on an algal community from a typical agricultural stream in Nebraska were studied using 18 stream microcosms located in a greenhouse, at six alachlor concentrations (0, 1, 10, 30, 100, and 1,000 μg/L). Effects of alachlor exposure at 1.0 μg/L were not significant (p < 0.05); however, at all other concentrations, alachlor had a significant negative effect on algal biomass. Differential taxonomic responses were observed, with approximately half the dominant algal taxa affected at levels >10 μg/L. Some taxa recovered from exposure by day 7, while others took longer or did not recover. A shift in the dominant algae was observed at higher concentrations (30, 100, 1,000 μg/L), and after 21 d these streams …

Susceptibility Of Stable Flies (Diptera: Muscidae) From Southeastern Nebraska Beef Cattle Feedlots To Selected Insecticides And Comparison Of 3 Bioassay Techniques, Paula C. R. G. Marcon, Gustave D. Thomas, Blair Siegfried, John B. Campbell

Department of Entomology: Faculty Publications

Insecticide susceptibility of field populations of stable flies, tomoxys calcitrans (L.), was assayed using 3 exposure techniques: treated filter papers, treated glass petri dishes, and topical applications. Both topical applications and residual exposure to treated glass surfaces were suitable for testing susceptibility of stable flies to permethrin, stirofos, or methoxychlor. Residues on filter papers yielded inconsistent results with stirofos and methoxychlor. Significant concentration-mortality regression lines were generated with permethrin residues on filter papers, but ~1,000 times more insecticide was required to produce a toxic response when compared with permethrin residues on glass. Because of higher variability in response and the …

Consideraciones Sobre El Género Opatrinus (Coleoptera: Tenebrionidae: Pedinini) En Cuba, Puerto Rico, Y Jamaica., Orlando H. Garrido, Esteban Gutierrez

Insecta Mundi

After obtaining fresh material of Opatrinus puertoricenis P uerto Rico a cornparison was done with a large series of . armasi. This latter taxon had been previously compared with Marcuzzi's original description, mainly based on his illustration of male genitalia from Jamaica reckoned to be O. puertoricenis. Genitalia from 0. p. puertoricenis (from Puerto Rico) and 0. armasi, proved to be quite alike. Also morphological characters of the two populations are not very distinct, offering differentiations better considered under subspecific rather than specific level. Therefore, we propose considering 0. arrrzasi Garrido and Gutiérrez, 1994, as a subspecies associated …
