Alternative control of root-knot nematodes (Meloidogyne javanica and M. enterolobii) using antagonists
The use of alternative ways to control pests and diseases in agriculture is becoming increasingly popular, as they are methods that do not cause a negative impact on the environment, unlike chemical pesticides. This research aimed to evaluate antagonistic plants (sorghum, crotalaria, mucuna, guandu bean and neem) in reducing the infestation of Meloidogyne javanica and […]
Comparative foraging behavior of eastern honeybee, (Apis cerana F) and western honeybee, (Apis mellifera carnica) in pollinating pear and apricot flowers in Taleghan, Iran
The Eastern honeybee, (Apis cerana), is indigenous to Asia and is an important pollinator for Asian ecosystems; the Western honeybee, (Apis mellifera), has been introduced to Asia because of its high honey yields. European honeybee, (Apis mellifera carnica) is native to the Iranian continent and is adopting apiaries by the beekeepers in Iran. The results […]
Analytical characterization of fatty acids present in seed oils by gas chromatography-Mass spectrometry and qualitative determination of various phytonutrients in dandelion plant
The current research was carried out to determine the phytochemicals constituents in the species of dandelion. Quantitative screenings of fatty acids was also carried out in our lab. Derivatives of methyl ester of fatty acids were analyzed. The analysis was carried out using gas chromatography coupled to mass spectrometer. The result of 19 different fatty […]
Bio geographical distribution of Trissolcus semistriatus Nees (Polygasteroidea: Scelionidae) an egg parasitoid of sunn pest, Eurygaster integriceps puton (Hemiptera: Scutelleridae) in Iran
Trissolcus semistriatus is an egg parasitoid showing the crucial role in plant protection as biological control agents on Eurygaster integriceps under different climatic conditions. The geographical distribution of T. semistriatus was studied using Maximum Entropy (MaxEnt) in different climatic regions of Iran. Records of 1161 specimens collected from 24 climates, altitude and climate variable data […]
Responses of Typha australis (Schum. & Thonn.) to a cutting of the stem
Typha australis (Schum. and Thonn.) is an invasive species that has grown considerably in northern Senegal. It is increasingly encountered in the Niayes of intensive farming. Typha causes inconvenience to human and the ecosystem. The control of the species is essentially made by cuttings. The results of which are inconclusive. The aim of this study […]
The habitat and estimation population of mamoa bird (Eulipoa Wallacei) in Galela-Halmahera
Mamoa birds (Eulipoa wallacei) is one of endemic bird species in Wallacea. Currently, egg-laying habitat and population of Mamoa was declined by degradation, fragmentation, and eggs harvesting. The aim of the research was to analyze the habitat and estimate the population of Mamoa in Galela North Halmahera. The method used were the combination of transect […]
Determination of population indices and weed distribution map in barley fields of Kermanshah Province, Iran
Weed detection of irrigated barley fields can be considered as the most important strategy for weed management of in this crop. Based on cropping area of barley and frequency of fields in each county of Kermanshah province, barley fields were selected. In order to identify and determine the abundance of weed species in irrigated barley […]
Study of seasonal changes in production and consumption of range plant Artemisia sieberi (Dehno- Kerman Province)
Artemisia sieberi is one of the appropriate forage plants to provide forage for livestock and it is suitable for soil conservation purposes in the steppe rangelands such as rangelands in Dehno (Kerman, Iran). Production and consumption of forage of Artemisia sieberi were carried out for four years. For this purpose, the residual forage after grazing […]
Diversity indices and importance values of a tropical deciduous forest of Chhotanagpur plateau, India
Ecological study was carried out by establishing four one hectare (ha) plots one each in Jiradih (site-I), Chargi (site-II), Sandoi (site-III) and Chiruvabera (site-IV) in December 2012 in the tropical deciduous forest around the Chhotanagpur plateau of Bokaro district, Jharkhand. At each site, 1-ha plot (100 m ˣ 100 m) was demarcated by nylon rope […]
Changes in activity profile of superoxide dismutase in barley cultivars seedling under salt stress
Salt stress is one of the most important factors limiting barley cultivation in arid and semi arid regions. Meanwhile, salt induced production of reactive oxygen species (ROS) induces the activity of some antioxidant enzymes in order to protect plants against stress condition. This study was aimed to investigate the activity of superoxide dismutase (SOD) in […]
