A total of 1752 strains of osrnophilic yeasts were isolated from honey and po]]ens. Fody-three strains Gf esmophilic yeasts produced po]yols, among whieh 6 strains produced erythritol in good yields. On the other hand, 52 osmophilic yeasts converted sucrose te fin]etooligosaccharides, among which 8 strains produced both extra and intracel]ular P-fructofuranosidase, which conyerted sucrose to fr...

Many species of tachinid flies are viewed as generalist parasitoids because what is apparently a single species of fly has been reared from many species of caterpillars. However, an ongoing inventory of the tachinid flies parasitizing thousands of species of caterpillars in Area de Conservación Guanacaste, northwestern Costa Rica, has encountered >400 species of specialist tachinids with only a...

an experiment was carried out in 2008-2009 to study the correlation between the reaction to potassium chlorate and pathogenicity on some iranian isolates of macrophomina phaseolina, the causal agent of soybean charcoal rot. from among a total of 48 collected isolates from the major soybean cultivation areas of golestan, mazandaran, ardabil, and lorestan provinces, twenty four isolates were sele...

Heat stress will restrict rice yield in the middle and lower reaches of Yangtze River. An understanding meteorological conditions heat production is important for improving accuracy phenology simulation. Based on observations agrometeorological stations this region, as well future scenarios, study analyzed spatiotemporal change its impacts growth region from 1990 to 2009. The results showed tha...
