    Notes: Abstract Oncocnemis chandleri, O. cibalis, andO. mackiei were attracted to chemically baited traps in the field. In all three cases, (5E,7Z)-dodecadienyl acetate was a key component for attraction. Attraction ofO. chandleri to traps baited with the (5E,7Z)-dodecadienyl acetate was inhibited by addition of (Z)-7-dodecenyl acetate.O. cibalis required both (5E,7Z)-dodecadienyl acetate and (Z)-7-dodecenyl acetate for attraction. Electroantennogram responses for the three species are also reported.

    Failure to detect an amorphous calcium-phosphate solid phase in bone mineral: A radial distribution function study (1984)
    Springer
    Calcified tissue international 36 (1984), S. 291-301 
    Details
    ISSN: 1432-0827
    Keywords: Bone ; Mineral ; Amorphous calcium phosphate ; X-ray diffraction ; Radial distribution function
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Medicine , Physics
    Notes: Summary X-ray diffraction radial distribution function analysis was used to determine if a significant amount of an amorphous solid phase of calcium phosphate exists in bone, and if so, whether the amount varies as a function of age and maturation. Unfractionated cortical bone from embryonic and posthatch chicks of various ages and a low-density fraction of embryonic bone were studied. No evidence was found for the presence of an amorphous solid phase of calcium phosphate in any of the samples studied, including the recently deposited bone mineral of the low density fraction of embryonic bone. As little as 12.5% of synthetic amorphous calcium phosphate (ACP) added to bone was readily detected by the radial distribution function technique used. The results clearly indicate that the concept that ACP is the initial solid mineral phase deposited in bone, and the major mineral constituent of young bone is no longer tenable. The concept does not provide an accurate description of the nature of the initial bone mineral deposited, or the changes that occur with maturation, nor can it acount for the compositional and X-ray diffraction changes that the mineral component undergoes during maturation and aging.

    Can strains give adequate information for adaptive bone remodeling? (1984)
    Springer
    Calcified tissue international 36 (1984), S. S118

    ISSN: 1432-0827
    Keywords: Bone ; Strain ; Remodeling ; Adaptation
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Medicine , Physics
    Notes: Summary For bone to remodel adaptively, the cells responsible should follow some algorithm. Nine different loading situations and structures are discussed. It seems that either algorithm must be extremely complex, or cells in different structures must follow different algorithms.

    Attraction of male spruce budworm moths,Choristoneura fumiferana (Clemens), to pheromone-baited traps in small-tree thinnings (1984)
    Springer
    Journal of chemical ecology 10 (1984), S. 125-133 
    Details
    ISSN: 1573-1561
    Keywords: Spruce budworm ; Choristoneura fumiferana ; Lepidoptera ; Tortricidae ; sex pheromone ; small-tree thinnings ; temperature ; precipitation ; wind ; attraction distance
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract Mean catches of spruce budworm,Choristoneura fumiferana (Clemens), moths were not significantly different among four small-tree thinning treatments of young spruce-fir-hemlock regeneration. Significant inverse relationships were found between trap catches and distances to nearby spruce-fir-hemlock overstory. Prevailing wind directions indicated that moths were attracted anemotactically to upwind pheromone sources. No definite trends were detected between catches and temperature or precipitation.

    Structure-activity relationships among aromatic analogs of trail-following pheromone of subterranean termites (1984)
    Springer

    Keywords: Termites ; Coptotermes ; Prorhinotermes ; Reticulitermes Schedorhinotermes ; Isoptera ; Rhinotermitidae ; structure-activity ; pheromone analogs ; trail-following pheromone
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract A series of 12 substituted (Z)-4-phenyl-3-buten-l-ol (PBO) derivatives were synthesized and evaluated for trail-following activity in five species of subterranean termites in the generaCoptotermes, Prorhinotermes, Reticulitermes, andSchedorhinotermes (Isoptera: Rhinotermitidae). The unsubstituted parent PBO was the most active for all species, and electron-withdrawing and electron-donating groups both reduced potency. Sensitivity to substitution in the ortho position suggests steric inhibition of binding by the 2′-substituted analogs. Different sensitivities to these pheromone analogs were found among the five species, withR.flavipes andS. lamanianus showing the highest level of trail-following activity for the PBO analogs.

    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract The chemical defense secretions of major and minor soldiers of over 18 colonies of the primitive glue-squirting nasute termiteLongipeditermes longipes (Isoptera, Termitidae, Nasutitermitinae) were analyzed chormatographically. The colonies, collected from four rainforest sites in peninsular Malaysia, showed monoterpene patterns rich in pinenes and limonene but with few quantitative differences between colonies. In marked contrast, the diterpene chemistry is high variable, and includes tricyclic (trinervitane), tetracyclic (rippertane), bicyclic (secotrinervitane), and a new spirotetracyclic (longipane) skeleton. Three new natural products are included in this remarkable and unprecedented example of structural diversity among different colonies of a single species.

    Sex pheromone components of fall cankerworm moth,Alsophila pometaria (1984)

    Notes: Abstract (Z,Z,Z,E)-3,6,9,11-Nonadecatetraene and (Z,Z,Z,Z)-3,6,9,11-nonadecatetraene, sex pheromone components ofAlsophila pometaria, were synthesized by stereoselective Wittig reactions and found to be spectroscopically and chromatographically identical to isolated natural material. Flight-tunnel bioassays and field-trapping experiments confirmed that the two tetraenes together with (Z,Z,Z)-3,6,9-nonadecatriene are sex pheromone components. While traps baited with either tetraene individually captured conspecific males in field-trapping experiments, addition of the triene, which captured no males by itself, to either tetraene resulted in synergistic responses.

    Notes: Abstract A sex pheromone extract from fall cankerworm moths,Alsophila pometaria, attracted conspecific males in field tests. Four EAG-active components were isolated from the extract and identified by GC-MS, highfield PMR spectroscopy, and microchemical techniques asn-nonadecane (I), (Z,Z,Z)-3,6,9-nonadecatriene (II), (Z,Z,Z,E)-3,6,9,11-nonadecatetraene (III), and (Z,Z,Z,Z)-3,6,9,11-nonadecatetrane (IV). Studies of the behavioral responses of male moths in a flight tunnel to the isolated components showed II, III, and IV were the major components of the sex pheromone. No sex pheromone behavioral responses were observed for I.

    Chemical composition and efficacy of cephalic gland secretion ofArmitermes chagresi (Isoptera: Termitidae) (1984)

    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract Soldiers of the neotropical humivorous termiteArmitermes chagresi have large ice-tong-like mandibles for mechanical defense and a moderate length nasus from which cephalic gland defensive secretions are discharged. Soldiers do not eject secretion, but ooze droplets which are held at the nasus tip by hairs. The chemical secretion is composed of C22–C26 macrocyclic lactones, including C24 and C26 and α- and β-hydroxylated lactones, with C24 macrolides predominating. The cephalic gland secretion has no pheromonal properties and does not induce alarm or attraction in soldiers or workers. Upon application, the secretion repels and is irritating to ants, but does not appear to act as an antihealant. The defensive behavior and chemistry ofA. chagresi is discussed in light of termite ecology and evolution.
