    Visual feedback in the control of pheromone-mediated flight ofHeliothis virescens males (Lepidoptera: Noctuidae) (1994)
    Springer
    Journal of insect behavior 7 (1994), S. 605-632 
    Details
    ISSN: 1572-8889

    Notes: Abstract MaleHeliothis virescens (F.) (Lepidoptera: Noctuidae) were made to fly into a uniformly white and translucent tube within a large wind tunnel while responding to sex pheromone. Different visual patterns placed within the tube greatly affected the ability of the male moths to maintain upwind progress or remain oriented to the wind while in contact with the plume. Over 89% of males attempting to fly through a blank tube, lacking visual patterns, became disoriented, the males gaining or losing altitude and repeatedly hitting the sides of the tube. Patterns of 20–40 dots placed on the sides of the tube at or slightly above plume level resulted in high levels of sustained upwind flight (47–74%) relative to patterns placed directly below (30–40%), directly above (35%), or slightly below the level of the flight path (26–44%). Optimal upwind progression in pheromone-responding males occurred when image motion could be resolved both transversely (T), orthogonally to the longitudinal axis of the body relative to the horizontal plane of the environment, and longitudinally (L), along the body axis. Even very sparse patterns (single rows of dots) could elicit high levels of sustained upwind flight (53–63%) when positioned within the tube such that the males' movements would create both L and T image motion. However, successful negotiation of the tube was also unexpectedly facilitated by patterns apparently providing no horizontal transverse component for flying males but providing longitudinal flow while centering the moth in the plume through a symmetrical left-right input (4–40%).

    Report of the Integrated Program Planning Activity for the U.S. Department of Energy Fusion Energy Sciences Program (2000)
    Springer
    Journal of fusion energy 19 (2000), S. 169-228 
    Details
    ISSN: 1572-9591
    Keywords: Fusion energy ; fusion program planning
    Source: Springer Online Journal Archives 1860-2000
    Topics: Energy, Environment Protection, Nuclear Power Engineering
    Notes: Abstract This report of the Integrated Program Planning Activity (IPPA) has been prepared in response to a recommendation by the Secretary of Energy Advisory Board that, “Given the complex nature of the fusion effort, an integrated program planning process is an absolute necessity.” We therefore undertook this activity to integrate the various elements of the program, to improve communication and performance accountability across the program, and to show the interconnectedness and interdependency of the diverse parts of the national Fusion Energy Sciences Program. This report is based on the September 1999 Fusion Energy Sciences Advisory Committee's (FESAC) report “Priorities and Balance within the Fusion Energy Sciences Program.” In its December 5, 2000, letter to the Director of the Office of Science, the FESAC reaffirmed the validity of the September 1999 report and stated that the IPPA presents a framework and process to guide the achievement of the 5-year goals listed in the 1999 report. The report also outlines a process for establishing a database for the fusion research program that will indicate how each research element fits into the overall program. This database will also include near-term milestones associated with each research element and will facilitate assessments of the balance within the program at different levels.

    Identification and bioassay of sex pheromone components of carob moth,Ectomyelois ceratoniae (Zeller) (1991)
    Springer
    Journal of chemical ecology 17 (1991), S. 1973-1988

    ISSN: 1573-1561
    Keywords: Flight tunnel ; gas chromatography-electrophysiology ; mass ; spectrometry ; aldehydes ; (Z,E)-9,11,13-tetradecatrienal ; (Z,E)-9,11-tetra-decadienal ; (Z)-9-tetradecenal ; pheromone ; Lepidoptera ; Pyralidae
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract Three sex pheromone components of the carob moth were isolated and identified from the extract of female pheromone glands, using a variety of techniques including coupled gas chromatographic-electroantennographic recordings, coupled gas chromatographic-mass spectrometric analysis, microozonolysis, electroantennographic assays of monounsaturated standards, wind-tunnel bioassays, and field trials. The major component was identified as (Z,E)-9,11,13-tetradecatrienal, a novel lepidopterous pheromone component structure. Two minor components, either one of which improves the upwind flight response of males when blended with the major component, were identified as (Z,E)-9,11-tetradecadienal, and (Z)-9-tetra-decenal.

    An equilibrium and stability study of Δ1-pyrroline (1992)
    Springer
    Journal of chemical ecology 18 (1992), S. 1595-1602

    ISSN: 1573-1561
    Keywords: 3,4-Dihydro-2H-pyrrole ; pheromone ; Δ1-pyrroline ; [1H]NMR spectroscopy ; [13C]NMR spectroscopy ; equilibrium ; Mediterranean fruit fly ; Ceratitis capitata ; Diptera ; Tephritidae

    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract Several properties of the compound 3,4-dihydro-2H-pyrrole(A1-pyrroline), which has been reported as a component of the male-produced Mediterranean fruit fly pheromone, have been determined by [1H]- and [13C]nuclear magnetic resonance spectroscopy. The stability of Δ1-pyrroline in several solvents and at moderately elevated temperatures has been investigated, and it has been established that it exists as both a monomer and trimer in solution. Although equilibrium studies indicate that the trimer is thermodynamically more stable than the monomer in solution, only the monomer was found in the vapor phase based on infrared analysis.
