Chironomid larvae of the three species causing a nuisance problem in Japan were examined for their susceptibility to Bacillus thuringiensis serovar israelensis. Sporeparasporal inclusion complex gave a rapid and high mortality to larvae of Chironomus yoshimatsui (Chironominae) and Hydrobaenus kondoi (Orthocladiinae) within 24 h. However, susceptibility of Tokunagayusurika akamusi (Orthocladiinae) to this serovar was low. 相似文献

The genus Agrobacterium was created a century ago by Conn who included it in the family Rhizobiaceae together with the genus Rhizobium. Initially, the genus Agrobacterium contained the non-pathogenic species Agrobacterium radiobacter and the plant pathogenic species Agrobacterium tumefaciens and Agrobacterium rhizogenes. At the end of the past century two new pathogenic species, Agrobacterium rubi and Agrobacterium vitis, were added to the genus. Already in the present century these species plus Agrobacterium larrymoorei were reclassified into genus Rhizobium. This reclassification was controversial and for a time both genus names were used when new species were described. Few years ago, after a taxonomic revision based on genomic data, the old species A. rhizogenes was maintained in the genus Rhizobium, the old species A. vitis was transferred to the genus Allorhizobium and several Rhizobium species were transferred to the genus Agrobacterium, which currently contains 14 species including the old species A. radiobacter, A. tumefaciens, A. rubi and A. larrymoorei. Most of these species are able to produce tumours in different plants, nevertheless the genus Agrobacterium also encompasses non-pathogenic species, one species able to nodulate legumes and one human pathogenic species. Taking into account that the species affiliations to five Agrobacterium genomospecies have not been determined yet, an increase in the number of species within this genus is expected in the near future. 相似文献

The genus Dichocarpum was established by W. T. Wang and Hsiao in 1964, who
divided the genus into 2 sections: Sect. Dichocarpum including 10 species distributed on the
mainland of E. Asia, and Sect. Hutchinsonia including 9 species native to Japan. M. Tamura
and L. A. Lauener made a revision of the genus in 1968, who divided the genus into 4 sections, three for the species of the mainland of E. Asia, including 3 series and 10 species, and
the other for the species of Japan, including 2 subsections, 3 series and 9 species. In the present paper, the genus is divided into 2 sections and 6 series, including 15 species and 3 varieties, and a putative phylogeny of the genus is proposed. The genus may be close to the genus
Asteropyrum, and these two genera are rather specialized in Thalictroides (Ranunculaceae),
because they have three very similar characters: the petal with a long claw, the stephanocolpate
pollen and the chromosome morphology. The genus has 2n=24, 35(36?), which indicates that
its basic number is X=6, and the species on the mainland of E. Asia (Sect. Dichocarpum)
may well be paleotetraploids, whereas those in Japan (sect. Hutchinsonia) are paleohexaploids. Most of the advanced species are distributed in Japan and the most primitive ones in
China and the Himalayas, the distribution pattern seggests that the Japanese members of this
genus might have immigrated from China in the Tertiary, and differentiated and evolved
there. The putative phylogeny of the genus is shown in Fig. 2 (at series level) 相似文献

Fivenew species of the genus Triotemnus from Morocco and Yemen are described. Triotemnus is a new genus of Scolytinae for the Yemen region. External morphology of the new species and all morphologically related species of the genus were studied. While the new species from Morocco are morphologically similar to the known species from the corresponding region, all three newly described species from Yemen, mainly two of them living in Socotra, are morphologically very different from all other known species of the genus. Geographical distribution and the probability of endemicity are discussed. 相似文献
