Zahedan City with a yearly rainfall of about 95 mm lies in the most arid area in the eastern part of Iran close to Pakistan border. This city with a population of more than 500,000 has the highest rate of population growth among the big cities...
Effects of nitrogen fertilization on population growth of two-spotted spider mites
serious pest, Tetranychus urticae Koch. So, life table parameters and population growth rate of two-spotted spider mite (TSSM) were compared with four nitrogen concentrations (namely, 0, 50, 80 and 100% of the recommended N level) on strawberries under...
Consequence of Different Nitrogen: Potassium Regime Ratios on performance of black bean aphid and related growth parameters change in bean
Life table parameters and population growth of Aphis fabae Scopoli (Hemiptera: Aphididae) were investigated in relation to different N:K fertilization ratios (40:60, 40:40, 40:0 kg/ha and control 0:0) on bean Phaseolus vulgaris L. under greenhouse...
Effect of Nitrogen Fertilizer on Biological Parameters of the Cowpea Aphid and Associated Productivity Losses in Common Globe Amaranth
Reducing nitrogen fertility of floriculture plants is an effective tactic to pest management with decreasing host plant quality. Life table parameters and population growth rate of Aphis craccivora, as well as cosmetic and qualitative parameters...
Studying the Structural Effects of High-rise Construction on Urban Environment Sustainability
Nowadays, High-rise Construction phenomenon is extremely developing in all around the world; this is
because of house shortage and population growth. From urbanism’s point of view, this phenomenon has
hidden dimensions and also plenty...
Effect of Ant Attendance on Aphid Population Growth and above ground Biomass of the Aphid’s Host Plant
.: Formicidae) on population growth and duration of different developmental stages of Aphis gossypii Glover (Hem.: Aphididae) were determined along with the consequences for the fitness of the host plant of the aphid, Vicia faba L., in greenhouse conditions...
Physical-spatial development pattern analysis in urban districts one and two in the West Mashhad
, and economic attractions because the population growth and the entry of immigrants and tourists have led to unplanned construction and vast changes in spatial-physical urban structure and its spread around the city to in recent years. Therefore, this study aims...
