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 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; …

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 …

Homology Among The Autosomal Chromosomes Of Boophilus Annulatus (Say) And B. Microplus (Canestrini), Bonnie S. Gunn

Theses and Dissertations - UTB/UTPA

Autosomes of Boophilus annulatus and B. microplus were compared using C- and G-bands to establish the degree of homology. Karyotypes of both species consisted of 20 autosomes and an XX:XO sex determination system with the X being the largest chromosome. All chromosomes of B. annulatus were acrocentric with heterochromatin limited to centromeric regions. The B. microplus karyotype was acrocentric with one band of noncentromeric heterochromatin occurring in three chromosome pairs. Interspecific comparisons indicated seven pairs of G-band homologous autosomes and three G-band homologous pairs when added interstitial heterochromatin was considered. The number three chromosome of both species showed variation in …

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 …

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 …

Emergence And Overwintering Brood Of Douglas-Fir Beetle Eight Years After The Clover Mist Fire On The Clarks Fork Ranger District, Shoshone National Forest, Wyoming, Kurt K. Allen

Judith E Pasek

The Douglas-fir beetle outbreak on the Shoshone National Forest is evaluated for the eighth consecutive year. Adult emergence in 1996 showed a single peak. Overwintering brood in 1996 were used to predict population levels for 1997. Brood levels declined from 1995 but 81% of the overwintering brood are adults. Damage levels (number of trees killed) was at its lowest point in the last 7 years, a 4.5 fold decline from 1995. Brood counts indicate a steady or slight increase in beetle populations; however, in most areas suitable host trees are becoming scarce.

Management alternatives include salvage and sanitation, tree baiting, …

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 …

Book Review: An Inordinate Fondness For Beetles (Evans, A.V. And C.L. Bellamy), Brett C. Ratcliffe

University of Nebraska State Museum: Entomology Papers

This nicely produced book is a visual celebration of beetles. Consider that it has 140 color photographs on 98 color plates . . . and 26 of those plates are of scarabs. Excellent! One should not construe my possible bias (or perhaps even that of the first author) as too narrow in its focus because the breadth of coverage of this volume is truly beetlewide.

In the Prologue, the authors briefly review the timeless fascination that humans have had with beetles. They note that most people are not aware of the diversity of beetles and are not impressed by such …

Tb163: Insect Predation Of Seeds And Plant Population Dynamics, Jianxin Zhang, Francis A. Drummond, Matt Liebman, Alden Hartke

Technical Bulletins

This review provides a framework for understanding the mechanisms of insect seed predation, the diversity of insects that prey on seeds, and the ecological and evolutionary consequences of insect seed predation. Insect seed predation can play significant roles in reducing plant population growth, modifying intraspecific and interspecific competition, shifting spatial and temporal distribution, affecting species evolution, and plant community structure, both in natural and agricultural ecosystems.

Analysis Of Gene Expression During Embryonic Development In Mulberry Silkworm Bombyx Mori, Amit Singh, K. P. Gopinathan

Biology Faculty Publications

We have developed a method for dechorionation and devitellinization of the silkworm eggs without damage, to facilitate the analysis of gene expression during embryonic development of Bombyx mori. Making use of antibodies available from heterologous systems, the spatio-temporal expression patterns of peroxidase and proliferating cell nuclear antigen have been directly visualized in whole mount embryos at various stages of development without the need for generating transformed ·lines carrying specific reporter constructs. The B. mori system, previously unamenable for such studies, could thus serve as an attractive model for molecular analysis of insect development.
