    Über den Einfluß der Kulturdauer im larvalen Wirt auf die Entwicklungsleistungen implantierter männlicher Genitalimaginalscheiben vonEphestia, kuehniella Z. (1979)

    Keywords: Lepidoptera ; Male genital disk ; Implantation ; Regeneration ; Control of metamorphosis
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Summary Complete and bisected male genital disks (HO) from full-grown (T9) larvae were transplanted either into larvae and pharate pupae of different age (T4, T7, T9 larvae, A1–A5 pharate pupae) or repeatedly transferred into full-grown larvae before being implanted into a final larval host. After metamorphosis of the hosts, most of the complete transplants and regenerated HO halves showed normal morphological features, but the implanted genitals from old pharate pupae (A4 and A5) were abnormally differentiated. Frequency of Regeneration. After transplanting both halves of the bisected HO into T9 hosts, three groups of results were observed: (1) each of the two halves regenerated into a complete genital organ; (2) only one half regenerated; (3) neither of the two halves regenerated. In the pharate pupae no regeneration of the implanted halves took place. If the lapse of time between the transplantation and, the onset of metamorphosis (=onset of pharate pupae phase) was long enough by transplanting into young larvae (T4) or by repeatedly transferring into old larvae and subsequent transplantation into a final larval host, all the implanted halves were able to regenerate. Size of the Implanted Genital Organs After prolonging the in vivo culture in larval hosts by implanting into young larvae or repeatedly transferring into old larvae, it was found that the regenerated genitalia grew to the same size as the complete transplants, but the size of the complete transplants increased, if at all, only insignificantly. Duration of Development of the Hosts. Regeneration of one HO half implanted into a full-grown larva caused an average delay of further development of about 2 days. An additional delay was recorded when both halves had regenerated. However, no delay was observed when HO halves implanted into young (T4) larvae regenerated, and no delay occurred in the final hosts when the repeatedly transferred halves had reached a certain stage of regeneration. The developmental capacities of the tranplanted disks and the control of metamorphosis by regenerating disks are discussed.

    Mutual inhibition of the attractant pheromone response by two species ofIps(Coleoptera: Scolytidae) (1975)
    Springer
    Journal of chemical ecology 1 (1975), S. 101-113 
    Details
    ISSN: 1573-1561
    Keywords: pheromone ; inhibition ; Scolytidae ; Ips ; pini ; paraconfusus ; ipsenol ; linalool
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract The bark beetles,Ips pini andI. paraconfusus, are not cross-attractive in the field although they attack the same host material at the same time. Logs containing the pheromone-producing sex (males) of both species side by side attract significantly fewer beetles of each species than do males of either species alone. Ipsenol, a component of the maleI. paraconfusus pheromone, duplicates the activity of maleI. paraconfusus in inhibiting the response ofI. pini to maleI. pini. Linalool from maleI. pini also reduces the catch ofI. paraconfusus in response to maleI. paraconfusus. Simultaneous production of a specific attractant pheromone and an interspecific chemical inhibitor favors exclusive use of the host substrate by the first arriving species.

    The chemical basis of attraction of ithomiine butterflies to plants containing pyrrolizidine alkaloids (1976)
    Springer
    Journal of chemical ecology 2 (1976), S. 255-262 
    Details
    ISSN: 1573-1561
    Keywords: pheromones ; Lepidoptera ; pyrrolizidines ; Ithomiinae ; Danainae ; alkaloids
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract The plantHeliotropium indicum L. (Boraginaceae) contains pyrrolizidine alkaloids. When dried, it is a powerful attractant for male ithomiine and danaine butterflies, which congregate and feed at its dead shoots. The butterflies use alkaloids derived from the plants for the formation of chemicals with pheromone/allomone activity. Baiting with alkaloids and “esterifying acids,” which form a part of the alkaloid molecules, indicates that a volatile product derived from the esterifying acids attracts males to the plants, where intact alkaloids then act as phagostimulants.

    Sex pheromone specificity as a reproductive isolating mechanism among the sibling speciesArchips argyrospilus andA. mortuanus and other sympatric tortricine moths (Lepidoptera: Tortricidae) (1977)
    Springer
    Journal of chemical ecology 3 (1977), S. 71-84

    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract MaleArchips argyrospilus (Walker) were maximally attracted to a 60∶40∶4∶200 admixture of (Z)-11-tetradecenyl, (E)-11-tetradecenyl, (Z)-9-tetradecenyl and dodecyl acetates. The identification of (Z)-9-tetradecenyl acetate, in addition to the other 3 components reported previously, is the first report of a 4-component pheromone system in moths.Archips mortuanus Kearfoot, a sibling species, was maximally attracted to a blend of the same components, but in a 90∶10∶1 mix of the tetradecenyl acetates. Among a number of tortricine moths that co-occur on apples and other hosts in New York, British Columbia, and elsewhere, differences in diel rhythms of attraction and seasonal distribution are insufficient to maintain reproductive isolation. Although the attractant systems of these species often possess components in common, males are maximally attracted to a speciesspecific blend. In tortricine moths attraction specificity appears to be a paramount mechanism for species partitioning.

    Female pheromone in the black molly fish (Mollinenesia latipinna): A possible metabolic correlate (1977)
    Springer
    Journal of chemical ecology 3 (1977), S. 207-217

    ISSN: 1573-1561
    Keywords: Black molly fish ; Mollinenesia latipinna ; pheromone ; thyroxine ; thiouracil ; general activity stimulus ; social contact
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract The female black mollyMollinenesia latipinna emits a water-borne pheromone which increases general activity and social contacts among males. Two hormones, thyroxine and thiouracil, administered to the females increase these behaviors in males. Apparently the hormones do not functionally compete in this species, and both seem to elevate the emission of the male stimulant.

    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract Chromatograms of the cuticular lipids washed from recently emerged female and maleFannia canicularis (L.) flies were nearly identical, but by the time the flies were 5 days old, the cuticular components of the two sexes differed considerably. A monoolefin which constituted 66% of the cuticular lipid from 5-day-old females stimulated a copulatory response from males and was identified as (Z)-9-pentacosene. The cuticular lipid of the same age males contained only 1% of this compound. Although all the major constituents of the cuticular lipid from mature females were hydrocarbons, 27% of the lipid washed from 5-day-old males was a nonhydrocarbon material that was represented by a single GLC peak. This material was identified as heneicosan-8-ol acetate.

    Notes: Abstract When placed in aY-maze, the 1–10-day-old free-swimming fry of the Midas cichlid can chemically distinguish between their mother and plain water and between another mother and plain water. They do not distinguish between the two mothers offered together or between their father and plain water. Predation pressures make these responses adaptive.
