The knowledge of field management zones based on soil attributes can be helpful for the implementation of site-specific management. This work had the objective of analyzing the spatial dependence of soil attributes of the 0-0.20 m and 0.20-0.40 m layers of an Entisols Quartzipsamments, in Petrolina, Northeast Brazil, which has been cultivated with micro sprinkler irrigated grapevines. In a rectangular grid with 168 points spaced by 4.0 x 3.5 m, soil samples were collected from each layer to determine soil bulk density, contents of clay, silt and sand, soil water contents at field capacity and wilting point. All data sets were submitted to classic statistical and geostatistical analyses. For the 0-0.20 m layer, the distributions of soil bulk density, clay content and soil water content at field capacity presented a spatial dependence structure, with ranges of 10.0 m, 8.3 m and 7.2 m, respectively. In the 0.20-0.40 m layer, spatial dependence was found for soil density, sand content (6.6 m for both attributes) and soil water content at field capacity (6.8 m range). Distributions of silt and sand contents and soil water content at wilting point presented no spatial dependence in the upper layer as well as the clay and silt contents and soil water content at wilting pointing in the deeper layer. By constructing the soil attribute contour maps, distinct management zones were defined as well as their extension. Practical uses for irrigation scheduling purposes were proposed. |

Chrysodeixis includens (Walker 1858), also known as soybean looper, is a polyphagous pest with increasing economic significance in various crops. The rate of infestation and its distribution can be in fluenced by feeding through direct and indirect effects on their life cycles. Thus, this study aimed to examine the biological character-istics, food preference and leaf consumption of C.includens on soybean (BRS 284), cotton (FMT 701), sun flower (BRS 323) and common morning glory leaves (Ipomoea sp.) as possible host plants. The experiments were conducted with specimens obtained from mass rearing in the laboratory.C. includens larval and larval-adult stages were shorter in sun flower and longer in cotton. Also, larval preference was greater for sun flower and lower for cotton leaves. Soybean leaves were consumed the least in contrast to sun flower and common morning glory leaves, which were consumed the most. These results suggest that soybean, sun fl ower or common morning glory leaves were favourable hosts for C. includens development, whereas cotton leaves are less nutritionally adequate for insect development. In addition, sun flower leaves reduce C. includens development time and promotes a survival rate greater than 95%, and the leaves are more attractive to larvae when compared with the other tested hosts. This indicates sun flower is the most favourable host among the tested plants for C. includens. |
