plants. The geographical and climatological condition of Querétaro city, and having a large industrial corridor are risk factors for development allergic problems. In Mexico there are no prevalence studies on food allergy and therefore the most common food allergens. The objectives of the study are to identify common allergen sensitization and to determine if there is crossreactivity between cy...

(1) Background: Coffee agroforestry systems (CAFS) in Veracruz, Mexico, are being displaced by avocado monocultures due to their high economic value. This change can generate alterations the type of organic residues produced and soil biological activity (SBA) which is sensitive climatic variations, changes floristic composition, agronomic management. It be evaluated through respiration macrofau...

The Persea mite, Oligonychus perseae Tuttle, Baker & Abbatiello (Acari: Tetranychidae), is an economically important foliar pest of avocados in Spain. effects this mite on the damage, production losses and economic impact were assessed two avocado, cv. Hass, orchards located main growing areas Spain (Northern Tenerife Málaga) for 3 5 consecutive years, respectively. injury level (EIL) optim...

The sex pheromone of Stenoma catenifer was evaluated in commercial avocado orchards in Guatemala to determine operational parameters, such as optimal lure type, trap height, trap density and estimates of the distances that male moths fly. Of four pheromone dispensers tested, gray and white rubber septa were of equal efficacy, whereas 1-ml low-density polyethylene vials and 2×3-cm polyethylene z...

In previous communications from this laboratory on the fate of ethylene in avocados, it was shown that approximately 127, of the radioactivity of metabolized ethylene-3H appeared in the methyl group of toluene (1) whereas only approximately 0.2% of the radioactivity of metabolized ethylene-14C appeared in toluene (2). On the other hand, benzene produced by the metabolism of ethylene-3H and ethy...

Differences in modes of control of glycolysis in tumor cells, compared with normal cells, have suggested that phosphofructokinase may not catalyse the rate-controlling step. Instead, hexokinase activity may assume a more important regulatory role. Hexokinase activities are consistently lower than those of phosphofructokinase in tumor cells, and the former enzyme may be saturated with its substr...
