Identification of the sex pheromone of Ostrinia palustralis 总被引:2,自引:0,他引:2

By means of gas chromatography with electroantennographic detection, gas chromatography-mass spectrometry and a series of bioassays, (E)-11-tetradecenyl acetate (E11-14:OAc) and (Z)-11-tetradecenyl acetate (Z11-14:OAc) at a ratio of 99:1 were identified as female sex pheromone components of Ostrinia palustralis. The average amounts of E11- 14:OAc and Z11-14:OAc in a single sex pheromone gland were 37.2±24.4 ng and 0.3±0.2 ng, respectively. In a wind-tunnel bioassay, the binary blend of E11- and Z11-14:OAc elicited the same male behavioral responses as did virgin females. 相似文献

The purpose of this research was to conduct reconstructions of concussive and non-concussive impacts in ice hockey to determine the biomechanics and thresholds of concussive injury in ice hockey. Videos of concussive and non-concussive impacts in an elite professional ice hockey league in North America were reconstructed using physical and finite element model methods. Eighty concussive and 45 non-concussive events were studied. Logistic regressions indicate significant thresholds for concussion for linear/rotational acceleration and CSDM10%. Impacts in ice hockey were mostly long duration events, longer than 15?ms. These results have significant implications for helmet standards and development to prevent concussion. 相似文献

The Drosophila melanogaster transposable element 412 is transiently unstable in Saccharomyces cerevisiae when present on a freely replicating plasmid. The 412 element undergoes recombination to form two circular molecules, a 412 deletion plasmid and, presumably, a 412 circle. The 412 deletion plasmid contains a single long terminal repeat which most likely is the result of homologous recombination within the long terminal repeats. This recombination occurs at or shortly after transformation and is independent of both the RAD52 gene product and the Flp gene of 2 micron DNA. 相似文献

Japanese horse chestnut (Aesculus turbinata: Hippocastanaceae) is one of the typical woody plants that grow in temperate riparian forests in the Japanese Archipelago.
To analyze the phylogeography of this plant in the Japanese Archipelago, we determined cpDNA haplotypes for 337 samples from
55 populations covering the entire distribution range. Based on 1,313 bp of two spacers, we determined ten haplotypes that
are distinguished from adjacent haplotypes by one or two steps. Most of the populations had a single haplotype, suggesting
low diversity. Spatial analysis of molecular variance suggested three obvious phylogeographic structures in western Japan,
where Japanese horse chestnut is scattered and isolated in mountainous areas. Conversely, no clear phylogeographic structure
was observed from the northern to the southern limit of this species, including eastern Japan, where this plant is more common.
Rare and private haplotypes were also found in southwestern Japan, where Japanese horse chestnuts are distributed sparsely.
These findings imply that western Japan might have maintained a relatively large habitat for A. turbinata during the Quaternary climatic oscillations, while northerly regions could not. 相似文献

The remodeling of the larval fat body is observed in many insects during metamorphosis, but little is known about the physiological importance or the regulation of this process. In Drosophila melanogaster, fat-body remodeling involves the dissociation of the fat body into individual fat cells, which persist throughout pupal development but are later removed by cell death in the young adult. Inhibition of fat-body dissociation is associated with pharate adult lethality and thus is likely to be an essential developmental event. As a start toward understanding the role of fat-body remodeling in the life history of insects, we carried out a detailed study of fat-body disassociation in D. melanogaster using fluorescent microscopy, and tested whether this process is mediated by hemocytes as proposed for fat-body remodeling in Sarcophaga peregrina. We identified and correlated stereotypic events in fat-body dissociation with developmental changes during metamorphosis, and have demonstrated by cell ablation studies that fat-body remodeling in D. melanogaster is a hemocyte independent process. 相似文献

This data paper reports litter fall data collected in a network of 21 forest sites in Japan. This is the largest litter fall data set freely available in Japan to date. The network is a part of the Monitoring Sites 1000 Project launched by the Ministry of the Environment, Japan. It covers subarctic to subtropical climate zones and the four major forest types in Japan. Twenty-three permanent plots in which usually 25 litter traps were installed were established in old-growth or secondary natural forests. Litter falls were collected monthly from 2004, and sorted into leaves, branches, reproductive structures and miscellaneous. The data provide seasonal patterns and inter-annual dynamics of litter falls, and their geographical patterns, and offer good opportunities for meta-analyses and comparative studies among forests. 相似文献
