    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.

    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.

    Notes: Abstract A slow release formulation of the bark beetle pheromones,endo- andexo-brevicomin, significantly reduced landing of southern pine beetles on host trees. Beetle flight activity within the infestation was not affected by the pheromones. The pheromones were released at approximately 600 mg/ha/day via Conrel® hollow fiber controlled-release dispensers.

    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.

    Notes: Abstract Each of 20 methyl-branched and 1,5-dimethyl-branched alkanes that comprise the active principle of saturated hydrocarbons of the female stable fly,Stomoxys calcitrans (L.), was synthesized and evaluated for mating stimulant activity. The compounds that showed the highest degree of activity in bioassays were 15-methyl- and 15,19-dimethyltritriacontanes.

    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.

    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract We attempted to suppress a population ofScolytus multistriatus (Marsham), the principal vector of Dutch elm disease, by trapping flying beetles on sticky traps baited with synthetic pheromone. The estimated catch on 421 traps distributed throughout a 1-km2 plot in Detroit, Michigan, was nearly 1 million beetles. Because an estimated 5 million beetles emerged in the plot during the study period, we conclude that this preliminary trapping study had no appreciable effect on suppressing the population. Studies that employ improved materials and techniques are continuing.

    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract AdultTrogoderma glabrum, T. inclusum, andT. variabile exhibit diel periods of exposure-concealment behavior, the frequency and duration of which are age-dependent, and the temporal placement of which is species-dependent. Exposure periods correspond with daily maxima in male sensitivity to the most active female-released sex pheromone component, 14-methyl-8-hexadecenal, and with respective periods of sex pheromone release in females. Exposure-concealment behavior may be a factor in reproductive isolation between these species, since potential communication distances are greatly reduced when either males or females are concealed.

    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract Volatile constituents present in nanogram quantities in various body parts and glands of the males and females of the speciesNeodiprion sertifer Geoffr. (Hymenoptera: Diprionidae) have been investigated by GC-MS. A significant amount of a volatile constituent was detected in the lateral parts of the integument of abdominal segments II-III. The constituent was identified as the furanoid monoterpenetrans-perillenal (I) previously not known to occur in nature. The identification and synthesis of this compound is described.
