Nest Usurpation, Supersedure And Colony Failure Contribute To Africanization Of Commercially Managed European Honey Bees In Venezuela, Robert G. Danka, Richard L. Hellmich, Thomas E. Rinderer

Richard L Hellmich

The fates of 58 colonies in 4 apiaries managed commercially for honey production in northwest Venezuela were determined during 15 months. All colonies had been previously requeened with marked European queens. Heritage of new queens (European daughter replacements versus Africanized usurpers) was traced by mitochondrial DNA and morphological characteristics of worker progeny. Three usurpations (5% of colony fates, at a rate of 4.7% of colonies per year) occurred. These colonies showed congruent African-derived mitochondrial DNA and Africanized morphology. Supersedures accounted for much of the introgression of African genes into the test apiaries. Twenty-eight colonies (48%) superseded their queens once, three …

Evidence For The Sensory Receptor(S) Of The Mounting Sex Pheromone In Two Species Of Ixodid Ticks, Dermacentor Variabilis (Say) And Dermacentor Andersoni Stiles, James Stephen Phillips

Biological Sciences Theses & Dissertations

The foreleg claw sensilla were determined to be the receptors of the female contact sex pheromone, MSP (mounting sex pheromone), in D. variabilis, D. andersoni and A. americanum male ticks. In all three tick species, the claw sensilla consists of six anteriorly-directed setae arranged in three symmetrical pairs, two each on the opposite sides of the apotele of the claw and one on the ventral side. Behavioral bioassays and morphological study of these setae revealed that only the dorsal and middle (= lateral) pairs of claw sensilla are mechanogustatory, while the ventral pair are strictly mechanoreceptors. The dorsal and …

Rice Insects: The Role Of Host Plant Resistance In Integrated Management Systems, E. A. Heinrichs

Department of Entomology: Faculty Publications

Insects are among the most important abiotic and biotic constraints to rice production. National rice research programs are in various stages in the development and implementation of integrated pest management (IPM) stratagies for rice insect control. Among the various control tactics, insect resistant cultivars are sought as the major tactic in rice IPM. Through the activities of interdisciplinary teams of scientists significant progress has been made in the development and release of insect resistant cultivars to farmers. Because of its compatibility with other control tactics insect resistance has proven to fit well into the IPM approach to rice insect control …

Book Review: Revision Of The Genus Spermophagus Schoenherr (Coleoptera, Bruchidae, Amblycerinae) , John M. Kingsolver

Insecta Mundi

Species in the genus Spermophagus are found in all of the Old World regions except Australia. Prior to this fine monograph, the taxonomy was a hodgepodge of local faunal treatments and single species descriptions with few usable keys or illustrations. Now we have available keys to 90 species with full descriptions, geographical distributions, and excellent illustrations of dorsal habitus, male genitalia, and many of the female genital valves.

Book Review: Aquatic Insect Ecology: 1. Biology And Habitat By J. V. Ward, Ross H. Arnett Jr.

Insecta Mundi

A comprehensive treatment of the ecology of aquatic insects in one place is needed for both students and researchers. Professor Ward is doing this in two volumes. The first volume covers the biology and habitats, as indicated in the subtitle, of the 13 insect orders that are either entirely aquatic at some stage, or those with some members aquatic at some stage. The second volume will be devoted entirely to the feeding ecology of these aquatic species.

Variation In The Terminalia Of Neohermes Concolor With A Key To Males Of Neohermes In Eastern North America (Megaloptera: Corydalidae: Chauliodinae), David E. Bowles, Michael A. Mathis

Insecta Mundi

Males of Neohermes concolor (Davis) from the interior highlands of Arkansas, Oklahoma, and Missouri, and from Illinois, Indiana, and Kentucky exhibited considerable variation in male terminalia. Differences occurred in the size of the dorsal membrane of the ninth sternite and in the shape of the tenth tergite (anal plate) which varied from rounded to truncate-shaped. This observed variation does not appear to be geographically correlated. Females of N. concolor did not exhibit broad variation in terminalii. Little variation was observed among males of N. angusticollis (Hagen) and N. matheri Flint. The broad range of variation observed in the tenninalia of …

Biochemical Characterization Of Hydrolytic And Oxidative Enzymes In Insecticide Resistant And Susceptible Strains Of The German Cockroach (Dictyoptera: Blattellidae), Blair Siegfried, Jeffrey G. Scott

Department of Entomology: Faculty Publications

We have identified resistance mechanisms in the German cockroach, Blattella gemanica (L.), for propoxur and chlorpyrifos in strains of cockroaches that display multiresistance to several organophosphate and carbamate insecticides. The resistance mechanisms involve the combined effects of increased oxidative and hydrolytic metabolism and both strains are resistant to chlorpyrifos and propoxur. Experiments designed to test for similarity in metabolic enzymes suggest that, although the mechanisms involve similar processes, the enzymes responsible for insecticide detoxification are different in the two strains. Both resistant strains exhibited enhanced activity toward a-naphtholic esters relative to a standard susceptible strain; however, analysis of the progeny …

Assessing Needs For Computer Pest Management Software In Nebraska Agriculture, Robert J. Wright

Department of Entomology: Faculty Publications

A mail survey was conducted to assess current computer hardware use and perceived needs of potential users for software related to crop pest management in Nebraska. Surveys were sent to University of Nebraska-Lincoln agricultural extension agents, agribusiness personnel (including independent crop consultants), and crop producers identified by extension agents as computer users. There were no differences between the groups in several aspects of computer hardware use (percentage computer use, percentage IBM-compatible computer, amount of RAM memory, percentage with hard drive, hard drive size, or monitor graphics capability). Responses were similar among the three groups in several areas that are important …

Mate Choice: Investigation Of Mating Preference For Siblings Versus Nonsiblings In The Solitary Vespid Wasp Euodynerus Foraminatus, Omoury A. Chambegga

Masters Theses

Caged wasps of Euodynerus foraminatus were given a choice of a sibling or a nonsibling for mates. Two types of experiments were conducted: female choice and male choice. For female choice experiments one female, a sibling male, and an unrelated male were introduced into an observation cage. For male choice experiments one male, a sibling female, and an unrelated female were introduced into an observation cage. Females preferred to mate with siblings, but males mated randomly with regard to family relationship.

Trends In Overwintering Egg Populations Of A Pine Sawfly, Neodiprion Autumnalis, On Ponderosa Pine Sampled In January And December 1991 Near Ft. Meade In South Dakota, Judith E. Pasek, Willis C. Schaupp Jr

Judith E Pasek

In 1990 and 1991, a number of outbreaks of the pine sawfly, Neodiprion autumnalis, were reported in western South Dakota and eastern Wyoming. Near Ft. Meade in South Dakota, defoliation in 1990 was heavy at the center of the infestation and decreased to light defoliation at a distance of 1 mile from the center. Defoliation at the same location in 1991 appeared to range from heavy to moderate.

Three sites near Ft. Meade that were sampled in January 1991 were resurveyed in December 1991 to assess changes in overwintering egg populations and degree of defoliation and to determine the potential …
