    Notes: Abstract Electroantennogram responses of male and femalePseudaletia unipuncta to the two major components of the presumed pheromone associated with the male anterior abdominal scent brushes vary with age. There is a postemergence period of maturation of responsiveness, followed by senescence. The age of maximum responsiveness differs according to the sex and to the compound tested.

    Specificity of trail markers of forest and eastern tent caterpillars (1979)
    Springer
    Journal of chemical ecology 5 (1979), S. 565-574 
    Details
    ISSN: 1573-1561
    Keywords: Lepidoptera ; Lasiocampidae ; Malacosoma americanum ; Malacosoma disstria ; Tortricidae ; Archips cerasivoranus ; trail marker ; pheromone ; interspecific response ; tent caterpillar

    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract Exploratory trails deposited on paper strips by the forest tent caterpillar (FTC),Malacosoma disstria Hubner, and the eastern tent caterpillar (ETC),M. americanum (Fabricius), as well as extracts of these trails, readily elicited interspecific trail-following behavior. In 2-choice tests involving simple Y mazes constructed from these paper strips, the caterpillars of both species preferred by approximately 3∶1 the trails of the FTC. Studies involving whole colonies of the ETC maintained under nearnatural conditions in the laboratory, however, indicated that the trails deposited by successful foragers of the ETC as they returned to their tent from feeding sites were more attractive than the exploratory trails of either the ETC or FTC. The pronounced interspecific response of these congeners to each other's trails suggests that they utilize either qualitatively similar or identical trail-marking chemicals. Both species preferred their own trails to those ofArchips cerasivoranus (Fitch) (Tortricidae), providing the first evidence that more distantly related lepidopterous larvae utilize distinct trails.

    Attraction and inhibition in moth species responding to sex-attractant lures containing Z-11-hexadecen-1-yl acetate (1977)
    Springer
    Journal of chemical ecology 3 (1977), S. 603-612

    Notes: Abstract Sex attractants for several sympatric noctuid moths required Z-11-hexadecen-1-yl acetate and additional olefinic compounds (coattractants) for effective, species-specific operation. In nearly all cases at least one of the coattractant compounds for each species functioned as a strong inhibitor of one or more of the other species in the group. It was concluded that species specificity in sex attractants can be achieved through conspecific coattractants which are at the same time transspecific inhibitors.

    Components of the sex pheromone of the female spotted stalk borer,Chilo partellus (Swinhoe) (Lepidoptera: Pyralidae): Identification and preliminary field trials (1979)

    Notes: Abstract FemaleChilo partellus (Swinhoe) abdominal tip extracts were examined by gas-liquid chromatography (GLC) combined with simultaneous electroantennographic (EAG) recording from the male moth. Two olfactory stimulants were detected and identified as (Z)-11-hexadecenal (I) and (Z)-11-hexadecen-1-ol (II) by their GLC behavior, microchemical reactions, and comparison with synthetic materials. Both compounds were detected in volatiles emitted by the “calling” female moth. Synthetic (Z)-9-tetradecenyl formate, a structural analog of aldehyde (I), also elicited a significant EAG response from the male moth. Field trials carried out in India using synthetic (I) and (II) as bait in water traps showed that compound (I) was highly attractive to maleC. partellus; compound (II) was not attractive, and its addition to (I) significantly reduced trap catches.

    Sex pheromone cross-attraction among four species of pine tip moths,Rhyacionia species (1979)

    Notes: Abstract Field tests utilizing crude pheromone extracts fromRhyacionia frustrana, R. rigidana, R. subtropica, andR. buoliana showed thatR. subtropica andR. buoliana were mutually attractive.R. frustrana was attracted in low numbers to bothR. subtropica andR. buoliana, butR. subtropica andR. buoliana did not significantly respond toR. frustrana. R. rigidana did not respond to pheromone extracts from any otherRhyacionia spp., nor was it attractive to the others. Cross-attraction occurred among those species which were largely allopatric and shared few tree hosts.

    Why are there so many species of herbivorous insects in tropical rainforests? (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-07-15
    Description: Despite recent progress in understanding mechanisms of tree species coexistence in tropical forests, a simple explanation for the even more extensive diversity of insects feeding on these plants has been missing. We compared folivorous insects from temperate and tropical trees to test the hypothesis that herbivore species coexistence in more diverse communities could reflect narrow host specificity relative to less diverse communities. Temperate and tropical tree species of comparable phylogenetic distribution supported similar numbers of folivorous insect species, 29.0 +/- 2.2 and 23.5 +/- 1.8 per 100 square meters of foliage, respectively. Host specificity did not differ significantly between community samples, indicating that food resources are not more finely partitioned among folivorous insects in tropical than in temperate forests. These findings suggest that the latitudinal gradient in insect species richness could be a direct function of plant diversity, which increased sevenfold from our temperate to tropical study sites.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Novotny, Vojtech -- Drozd, Pavel -- Miller, Scott E -- Kulfan, Miroslav -- Janda, Milan -- Basset, Yves -- Weiblen, George D -- New York, N.Y. -- Science. 2006 Aug 25;313(5790):1115-8.
