fruit fly, ceratitis capitata (diptera:tephritidae), worldwide. to determine the best combination of trap and attractant for mass trapping of mediterranean fruit fly, a field experiment was conducted in a randomized complete block design (rcbd) with 6 treatments in 3 replications in a pomegranate orchard in shiraz (iran) in 2009. treatments included: 1-jackson trap baited with trimedlure, 2- mc...

the leopard moth, zeuzera pyrina (l.) (lepidoptera: cossidae) is a serious pest of walnut and apple trees in iran. one of the control methods for this pest is the mass trapping of males using pheromone traps. to determine the best size and color of traps, four different colors (green, yellow, white, gray) and two different sizes (delta shape with standard adhesive surface, 19 × 22 cm and trapez...

A series of field experiments was conducted in cranberry bogs in 2006e2010 to determine adult attraction of the two most economically important leafhopper pests of cultivated Vaccinium spp. in the northeast USA, the blunt-nosed leafhopper, Limotettix vaccinii (Van Duzee), and the sharp-nosed leafhopper, Scaphytopius magdalensis (Provancher), to colored (yellow, green, red, blue, white, and clea...

We study a continuous-space version of the totally asymmetric simple exclusion process (TASEP), consisting of interacting Brownian particles subject to a driving force in a periodic array of potential wells. Particles are inserted into the leftmost well at rate α, hop to the right at unit rate, and are removed at the rightmost well at rate β. Our study is motivated by recent experiments on coll...

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...

During the 2012 pilot field season, we visited an operating wind farm to estimate effects of turbines on local insect abundance. We sampled at Foote Creek Rim I, an established 69 turbine wind farm in operation since 1999. We collected terrestrial invertebrates upwind and downwind of an operating turbine by setting up 13 stations spaced 20 m apart, with 2 stations upwind and 11 stations downwin...

in this study, postharvest characteristics of eight cut rose cultivars (valentine, king pride, prima donna, black baccara, victory, papagayo, royal baccara and yellow island) were investigated in a growth room with temperature of 20 ºc, relative humidity of 50% and light intensity of 10 µmol m-2 s-1 in autumn 2008. among cultivars significant differences were found for all of the attributes eva...

flea beetles of chaetocnema tibialis (col:, chrysomelidae) are important pests on sugar beet iniran. in some cases, the damages caused by this pest are so high that some part of  the field should be replanted. since most of crop losses occur from cotyledon stage until 4-leaf stage, monitoring of the population of this pest could play an important role in decreasing damage of the pest. sticky-co...

Separately collected urine (“yellow water”) can be utilized as fertilizer. In order to decrease storage volumes and energy consumption for yellow water transport to fields, enrichment of nutrients in yellow water has to be considered. Laboratory-scale batch freeze concentration of yellow water has been tested in ice-front freezing apparatus: a stirred vessel and a falling film freeze concentrat...

Serangga hama adalah hewan yang dapat menyebabkan kerugian pada petani. Pengendalian serangga menggunakan aplikasi pestisida ataupun perangkap. Tujuan dari penelitian ini untuk mengetahui kelimpahan masing perangkap terhadap beberapa teknik pengendalian berbeda. Metode eksperimental digunakan yaitu dengan Rancangan Acak Kelompok (RAK) faktor tunggal, terdapat 6 ulangan dan 4 perlakuan terdiri :...
