Comparative Population

In this study, we investigated the population growth of the Liposcelis yunnaniensis (Psocoptera: Liposcelididae) feeding on ten different diets. Out of the ten diets, eight were made of plain cereals namely wheat ( Triticum aestivum L.), corn ( Zea mays L.), barley ( Hordeum vulgar L.), oats ( Avena sativa L.), rice ( Oryza sative L.), and sorghum ( Sorghum bicolour L.) while two were the artificial diets named Nayak wheat diet and Universal diet. The population growth was recorded as corn > wheat > universal diet > hulled barley > rice (hulls intact) > barley (hulls intact) > sorghum > Nayak wheat diet > oats > hulled rice. After 32 d culture, the initial 5 psocids developed to the populations as 41.8 ± 4.26, 41.5 ± 4.09 and 39.1 ± 7.64 on corn, wheat and universal diet, respectively. Meanwhile, psocids feeding on Nayak wheat diet, oats and hulled rice had significantly lower populations with 25.6 ± 2.42, 22.5 ± 3.09 and 13.6 ± 2.36 respectively. Rice and barley were included in the diets with and without hulls to see their effect on population growth. In case of barley, hulls had no significant effect on population growth while rice with hulls had significantly higher populations than rice alone. This study has confirmed the relative level of suitability of different cereals for this species when damaged. We have described a method to get the uniform age adults that can be helpful in research experiments.

A determinação da concentração de compostos no solo por meio de plantas quantificadoras apresenta como principal vantagem detectar somente resíduos biologicamente ativos, não havendo necessidade de instrumentos onerosos e de prévia extração dos resíduos do solo. Dessa forma, este trabalho teve como objetivo selecionar plantas quantificadoras da presença de herbicidas residuais (pré emergentes) para o uso em bioensaios. Utilizou-se delineamento experimental completamente casualizado com arranjo bifatorial 8 x 6, com cinco repetições. O fator A consistiu de espécies cultiváveis e o fator B de herbicidas aplicados em pré emergência. Os resultados evidenciaram que a sensibilidade na detecção do herbicida no solo depende da espécie utilizada. A sensibilidade das espécies Lactuca sativa L. e Raphanus sativus var. sativus L. não permitiu condições de quantificar a presença dos herbicidas atrazina, cloransulam, imazaquin, metribuzin e S-metolacloro. Raphanus sativus var. oleiferus Metzger é potencial quantificador de imazaquin e S metolacloro. Plantas de Curcubita pepo L. são promissoras na bioavaliação de metribuzin. A espécie Cucumis sativus L. mostrou-se potencial bioindicadora de cloransulan e imazaquin. Avena sativa L. apresentou-se como potencial quantificadora de imazaquin e metribuzin. Hordeum vulgare L. pode quantificar o metribuzin e Triticum aestivum L. é promissor na detecção da biodisponibilidade de atrazina.

Water Depletion

Knowledge of soil water use in different crops and among crop cultivars is useful in crop rotation planning. Net seasonal soil water depletion patterns in the 0- to 130-cm soil profile for semidwarf and tall cultivars of oat (Avena sativa L.) and wheat (Triticum aestivum L.) were compared at 3 site-years in Manitoba. Total soil water depletion was greater for oat than wheat (29–31 mm). This trend was consistent across site-years and N regimes. Greater water use for tall versus semidwarf oat was observed at one of three sites. Key words: Cultivars, oat, semidwarf, soil water depletion, wheat

El estudio tuvo como objetivo evaluar los parámetros cinéticos de la degradación in situ de la materia seca (MS), proteína cruda (PC) y la estimación del consumo mediante ecuaciones de predicción de MS de forrajes y alimentos concentrados en alpacas Huacaya (Vicugna pacos). Se trabajó con ensilado de maíz chala (Zea mays L) sin y con 1% de urea, cebada (Hordeum vulgare L), avena (Avena sativa L), salvado de trigo (Triticum aestivum L) y raspa de papa (Solanum tuberosum). Los alimentos (5 g en base seca) fueron colocados en sacos de nylon e incubados en el primer compartimento estomacal de dos alpacas fistuladas durante 0, 6, 12, 24, 48 y 76 horas. Se analizó la MS y la PC de los residuos de los sacos. La MS y la PC del salvado de trigo y de la raspa de papa presentaron potenciales de degradación elevados, así como la MS y la PC de la avena. Se destaca la mayor fracción no degradable de la PC del maíz chala sin y con urea y, por tanto, una menor degradabilidad de la PC. Las estimaciones del consumo por las alpacas generadas por las ecuaciones de tres estudios no son adecuadas a los alimentos en estudio.
