neoseiulus californicus (mcgregor) is a predatory mite that can control spider mites. the effect of seven strawberry cultivars (including: ‘marak’, ‘yalova’, ‘aliso’, ‘gaviota’, ‘sequoia’, ‘camarosa’ and ‘chandler’) on the growth and development of n. californicus was studied in the laboratory conditions (27 ± 1 °c, 70 ± 5% rh and 16l: 8d photoperiod). there was significant difference in the nu...
In living organisms heme is formed from the common precursor uroporphyrinogen III by either one of two substantially different pathways. In contrast to eukaryotes and most bacteria which employ the so-called "classical" heme biosynthesis pathway, the archaea use an alternative route. In this pathway, heme is formed from uroporphyrinogen III via the intermediates precorrin-2, sirohydrochlorin, s...
The nitrogenase enzyme complex of Methanosarcina barkeri 227 was found to be more sensitive to NaCl than previously studied molybdenum nitrogenases are, with total inhibition of activity occurring at 190 mM NaCl, compared with >600 mM NaCl for Azotobacter vinelandii and Clostridium pasteurianum nitrogenases. Na+ and K+ had equivalent effects, whereas Mg2+ was more inhibitory than either monoval...
Archaebacterium, Methanosarcina, Methanol, Iron, Mössbauer, Ferredoxin Cells of the archaebacterium Methanosarcina barkeri were grown strictly anaerobic in defined media. 57Fe-Mössbauer Spectroscopy of methanol grown cells oxidized in the presence of air demonstrated only the state of Fe3+ whereas active cells under reducing conditions offered spectra of two additional iron sites in the Fe2+ st...
In natural environments methane is usually produced by aceticlastic and hydrogenotrophic methanogenic archaea. However, some methanogens can use C(1) compounds such as methanol as the substrate. To determine the contributions of individual substrates to methane production, the stable-isotope values of the substrates and the released methane are often used. Additional information can be obtained...
Lagenophora schmidiae de Lange & Jian Wang ter sp. nov. (Asteraceae) is described, illustrated and differentiated from L. montana Hook.f. The new species was first recorded Aotearoa / New Zealand in 1974, when it identified as montana. This relatively recent recognition reflects part the fact that extremely uncommon, has often been confused with superficially similar barkeri Kirk, which gro...
Amblyseius swirskiiAthias-Henriot (Acari: Phytoseiidae) is a predatory mite used to control thrips (Thysanoptera), whiteflies (Bemisia tabaci Genn., Hemiptera: Aleyrodidae), and broad mites (BMs) (Polyphagotarsonemus latus Banks, Acari: Tarsonemidae). Dispersal of A. swirskii, using the ornamental pepper "Explosive Ember" as a banker plant was evaluated for control of BMs in high-tunnel peppers...
