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 …

Seasonal Variation In The Essential Oil Composition Of Commiphora Quadricincta And Its Effect On The Maturation Of Immature Adults Of The Desert Locust, Schistocerca Gregaria, Y. O.H. Assad, B. Torto, A. Hassanali, P. G.N. Njagi, N. H.H. Bashir, H. Mahamat

All Peer-Reviewed Publications

Extracts of steam distillates of the desert shrub Commiphora quadricincta were tested for their effects on the maturation of gregarious immature males and females of the desert locust, Schistocerca gregaria. Maturation was significantly faster in immature adults exposed to the extract obtained before winter rains than in those exposed to the extract obtained after the rains, with respect to locust colour changes (yellowing of body), mating activity, aggregation-maturation pheromone titres (as measured by phenylacetonitrile levels in males), ovulation (as determined by the length of oocytes in females) and oviposition time. A large number of the compounds in the crude extracts …

Identification Of Components Of The Oviposition Aggregation Pheromone Of The Gregarious Desert Locust, Schistocerca Gregaria (Forskal), M. M. Rai, A. Hassanali, R. K. Saini, H. Odongo, H. Kahoro

All Peer-Reviewed Publications

Acetophenone and veratrole have been identified as two major behaviourally active components of the oviposition aggregation pheromone of the desert locust, Schistocerca gregaria. These compounds were identified from the volatiles of egg pod froth using gas chromatography-electroantennographic (GC-EAD) and gas chromatography-mass spectrometric (GC-MS) analysis. Both compounds were shown to elicit aggregation of gravid females in oviposition bioassays; however, they do not act synergistically. Both acetophenone and veratrole individually at optimum doses induced about 70% egg laying, a value similar to that evoked with froth volatiles.

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 …

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.

Cloning And Expression Of A Bacillus Thuringiensis (L1-2) Gene Encoding A Crystal Protein Active Against Glossina Morsitans Morsitans And Chilo Partellus, Edward O. Omolo, M. Diane James, Ellie O. Osir, Jennifer A. Thomson

All Peer-Reviewed Publications

A local isolate of Bacillus thuringiensis, designated L1-2, that is toxic to Chilo partellus was found to be toxic to the adult tsetse fly, Glossina morsitans morsitans. The δ-endotoxin crystals derived from the isolate gave a major protein band with a molecular weight of M(r) 130,000- 140,000 on denaturing polyacrylamide gel electrophoresis. The sequence of the cloned gene was found to be similar to that of the B. thuringiensis subsp. kurstaki HD-73 cryIA(c) gene, having one amino acid difference at position 148 and four additional DNA differences.

Winter Activity Patterns Of American Martens (Martes Americana): Rejection Of The Hypothesis Of Thermal-Cost Minimization, Gary S. Drew, John A. Bissonette

Green Canyon Environmental Research Area, Logan Utah

Despite their temperate to subarctic geographic range, American martens (Martes americana) possess a thermally inefficient morphology. The lack of morphological adaptations for reducing thermal costs suggests that marten may use behavioral strategies to optimize thermal budgets. During the winters of 1989-1990 and 1990-1991, we radio-collared and monitored the diel activity of 7 martens. A log-linear model suggested that the presence or absence of light was the only factor associated with marten activity patterns (p < 0.001). A regression of the percentage of active fixes on ambient temperature failed to detect an association (b = -4.45, p = 0.084, n = 12). Contents of marten seats suggested that their activity was consistent with the prey-vulnerability hypothesis. While martens must balance multiple life requisites, their activity patterns suggest that they accept increased thermal costs in order to increase foraging efficiency. However, the nocturnal activity of martens during winter was also consistent with the hypothesis that they may be able to limit their own exposure to predation risk. The nocturnal habits of Newfoundland martens in the winter were consistent with the hypothesis of avoidance of predation risk.

Seasonal Occurrence Of Rice Yellow Mottle Virus In Lowland Rice In Côte D’Ivoire, E. A. Heinrichs, A. A. Sy, S. K. Akator, I. Oyediran

Department of Entomology: Faculty Publications

Monthly plantings of the rice variety Bouaké 189 were made under lowland irrigated conditions, to obtain information on the phenological and seasonal occurrence of pests and diseases on the West African Rice Development Association (WARDA) research farm near Bouaké, Côte d’Ivoire. Regular sampling of insect pests and observations on rice yellow mottle virus (RYMV) disease infection throughout the year provided information on the occurrence of RYMV and potential insect vectors. RYMV incidence and grain yields varied depending on planting date, and for a given planting date, varied from one year to another. There was no evidence that RYMV incidence increases …

Oviposition Pheromone In The Simulium Damnosum Complex: Biological Activity Of Chemical Fractions From Gravid Ovaries, P. J. Mccall, R. R. Heath, B. D. Dueben, M. D. Wilson

Entomology Papers from Other Sources

Communal oviposition in the Afrotropical blackfly species complex Simulium damnosum Theobald (Diptera: Simuliidae) is mediated by a pheromone emitted by freshly laid eggs. Previously, two compounds (designated peaks A and B) emanating from fresh eggs were shown to be associated with attractiveness to gravid blackflies in bioassay. The present study investigated the role of these compounds by testing the responses of wild-caught Simulium yahense in Ghana to fractionated hexane extracts of gravid ovaries prepared by gas chromatography (GC). Although the fractions were prepared from Sierra Leonean Simulium teonense, GC analysis of the emissions from fresh S. yahense eggs showed …

Control Of Solenopsis Invicta With Teflubenzuron, D. F. Williams, W. A. Banks, C. S. Lofgren

Entomology Papers from Other Sources

Teflubenzuron baits were active against laboratory colonies of the red imported fire ant, Solenopsis invicta Buren. Worker brood production ceased soon after treatment and by four weeks posttreatment, most colonies were devoid of brood. Worker ants did not exhibit any direct effects from treatment with teflubenzuron. As is typical with most insect growth regulators, colony mortality was slow and dependent on old- age attrition of the worker ants. A few (<25) female alates were produced in one of the laboratory colonies at 12 weeks posttreatment.

Problems With The Interpretation Of Mark-Release-Recapture Data In Subterranean Termites (Isoptera: Rhinotermitidae), Anthony D. Curtis, Deborah A. Waller

Biological Sciences Faculty Publications

The Lincoln index (Peterson method) is frequently used to estimate animal population size in mark-release-recapture studies. We tested the accuracy of this method to estimate termite colony size using logs infested with termites that were maintained in the laboratory. Termites were fed paper towels dyed either with 0.05% or 0.1% (w/w) of the dye marker Nile blue and released into their host logs in the laboratory. Following recapture a week later, estimates of termite population size for termites dyed with 0.05% Nile blue, and were approximately 3 times greater for termites dyed with 0.1% Nile blue. Concentrations of 0.1% Nile …

Mitochondrial Dna Variation Among Muscidifurax Spp. (Hymenoptera: Pteromalidae), Pupal Parasitoids Of Filth Flies (Diptera), David B. Taylor, Richard D. Peterson Ii, Allen L. Szalanski, James J. Petersen

A mail survey was conducted of independent crop consultants in 12 midwestern U.S. states working in corn (Zea mays L.), soybeans [Glycine max (L.) Merrill], wheat (Triticum aestivum L.), and grain sorghum (Sorghum bicolor L. Moench.) during 1993. The survey was conducted to document the acreage of crops monitored by crop consultants, and some of their operational characteristics. Kansas and Nebraska had the greatest reported acreage of crops scouted, over 3 million and 1 million acres, respectively. Total acres scouted were highest for corn, followed by soybeans, wheat, alfalfa (Medlcago sativa L.), and sorghum. Acres …

The Impact Of Ixodiphagus Hookeri, A Tick Parasitoid, On Amblyomma Variegatum (Acari: Ixodidae) In A Field Trial In Kenya, E. N. Mwangi, S. M. Hassan, G. P. Kaaya, S. Essuman

All Peer-Reviewed Publications

In an experiment to investigate the effect of the tick parasitoid, Ixodiphagus hookeri, on tick numbers on cattle, 150 000 parasitoids were released over a period of 1 year in a field where ten cattle infested with multiple tick species were kept. Amblyomma variegatum was reduced from 44 to two ticks per animal while Rhipicephalus appendiculatus increased over the time of parasitoid release. During the time of release 51% of the nymphs of A. variegatum collected from the animals were parasitized. The recovery of the parasitoids after the releases were stopped was only 9%. The total numbers of A. variegatum …

Suitability Of West African Gramineous Stemborers For The Development Of Cotesia Species, Y. Hailemichael, F. Schulthess, J. W. Smith, W. A. Overholt

All Peer-Reviewed Publications

The palaeotropical, gregarious, endoparasitic braconids Cotesia sesamiae, Cotesia flavipes and Cotesia chilonis were recently imported into Benin as candidates for biological control of stem and cob borers of maize. Host acceptability and host suitability of six gramineous borers occurring in western Africa, namely the noctuids Sesamia calamistis, Sesamia poephaga, Busseola fusca and the pyralids Contesta ignefiisalis, Eldana saccharina and Mussidia nigrivenella, to these candidate parasitoids was evaluated in order to gain insight into the physiological suitability of the natural and factitious hosts. All hosts were accepted by all Cotesia spp., except M. nigrivenella which was not attacked by Co. chilonis. …
