The beet armyworm, Spodoptera exigua, is the most destructive pest of sugar beet in many regions of the world including Iran. In this study, the effect of some potential resistance inducers (salicylic acid, calcium silicate and sodium silicate) for reducing the pest density were investigated in sugar beet field. The inducers were applied in 100 and...

Spodoptera exigua Hübner and Sesamia cretica Led. (Lep., Noctuidae) are two important pests of corn. In this study, the effect of weed bands in the corn field, as weedy culture, on population density and damages of the pests were evaluated during two growing seasons (2016/2017). Cumulative insect days (CID) of each lepidopteran pest in weedy cultur...

Aphis gossypii Glover (Hemiptera: Aphididae) is an important cucumber pest especially in greenhouse. The efficacy of simultaneous release of generalist predator, Orius albidipennis Reuter (Hemiptera: Anthocoridae) and a specialist parasitic wasp, Aphidius colemani Viereck (Hymenoptera: Braconidae), was evaluated in laboratory conditions against the...

Aphis spiraecola Patch, Aphis gossypii Glover, and Toxoptera aurantii Boyer de Fonscolombe are three important aphid pests of citrus orchards. In this study, spatial distributions of the aphids on two orange species, Satsuma mandarin and Thomson navel, were evaluated using Taylor's power law and Iwao's patchiness. In addition, a fixed-precision seq...

The purpose of this study was to check the possibility of callus and somatic embryogenesis in date palm cv. Khazravi using different explants including leaves, green fruit, immature seed, endosperm and green fruit pericarp. In the culture of leaves in the medium contains different plant growth regulators including 2,4-D, BAP and TDZ, highest callus...

Ephestia kuhniella is one of the most important stored pests in the world. Repellency and biological effects of various ultrasonic signals with different frequencies and wave shapes on adult, larvae and pupae of the pest were studied in laboratory conditions. Choice and non-choice tests was performed by an invented signal generator device. In choic...

Large‐scale selective genotyping and high‐throughput analysis are two important strategies for low‐cost and high‐effective genetic mapping. In this study, selective genotyping was applied to four maize F2 populations. Thirty plants were selected from each of the two tails of the original F2 populations to represent extreme resistant and susceptible...

With 2 tables Abstract Recombination frequency greatly affects selection efficiency in plant breeding. A high‐density single‐nucleotide polymorphism (SNP) map integrated with physical map and other molecular maps is very useful for characterizing genetic recombination variation. In this study, recombination frequency in maize was investigated thro...

This paper describes two joint linkage-linkage disequilibrium (LD) mapping approaches: parallel mapping (independent linkage and LD analysis) and integrated mapping (datasets analyzed in combination). These approaches were achieved using 2,052 single nucleotide polymorphism (SNP) markers, including 659 SNPs developed from drought-response candidate...

Genetic variation of 28 populations of jointed goatgrass (Aegilops cylindrica Host.), collected from different parts of Iran, were evaluated using both RAPD-PCR and SDS-PAGE of seed proteins. The diversity within and between populations for the three-band High Molecular Weight (HMW) subunits of glutenin pattern were extremely low. Out of 15 screene...
