pollination and pest control are perhaps the best-known ecological services performed by hover flies. the species diversity and their abundance have an influential impact on the ecological services provided by this family. to find out species diversity of adult flower flies associated with agroecosystems in kerman province, a biodiversity survey using insect net and color water traps was conduc...

purpose : to determine the distribution of iris colors in the population of tehran and to assess possible associations between iris color and ocular disorder methods : through a stratified random cluster sampling approach, 160 clusters were selected in different municipality districts of tehran, and the approached households were invited to a clinic. after the initial interview, all participant...

the mode of inheritance of seedling color and plant pubescence was studied in two crosses among three parents, which differed for these traits. the results have revealed that purple seedling color was dominant over green seedling color and pubescence was dominant over nonpubescence. these two traits segregated independently of each other may be used as morphological markers individually for dif...

Several studies document rudimentary color vision under dim illumination. Here, hue perceptions of paper color samples were determined for a wide range of light levels, including very low light levels where rods alone mediate vision. The appearances of 24 paper color samples from the OSA Uniform Color Scales were gauged under successively dimmer illuminations from 10-0.0003 Lux. Triads of sampl...

We conducted two experiments to determine the best CDC-trap configuration for catching male and female Phlebotomus papatasi. First, visual features were evaluated. Standard CDC traps were modified to have black or white catch bags, black or white lids, or no lids and these were tried in different combinations. Significantly more male sand flies were caught by darker traps; significantly more fe...

Field experiments were conducted to determine the effectiveness of different colored pheromone-baited traps in capture of Fall Armyworm, Spodoptera frugiperda , males and nontarget Hymenoptera. Plastic Universal Moth Traps (Unitraps) of different colors were baited with commercial sex pheromone and were placed in peanut and corn fields in northern Florida. In one study, standard-colored (green ...

to study the effects of different fertilizing systems using green manure and zeoponix on grain yield and its components in sunflower, an experiment was conducted at the research farm of collage of agriculture, tarbiat modares university in 2010 and 2011. the experimental treatments were arranged as split plot design on the base of a complete randomized block design with three replications. two ...
