it has been hypothesized that the survival, development, fecundity and population of insects are affected significantly by high temperatures. the diamondback moth, plutella xylostell (l.) (lepidoptera: plutellidae), is a serious and economically important pest of cruciferous crops throughout the word. in this research, the adult longevity and fecundity of p. xylostella were studied in laborator...
the laelapid mite, gaeolaelapsaculeifer (canestrini) is widespread in soil habitats and feeds on different small arthropods, fungi and nematodes. the development and fecundity of g. aculeifer feeding on rhizoglyphus echinopus (fumouze & robin) as prey was studied at eight different constant temperatures which include: 16, 17.5, 20, 22.5, 25, 27.5, 30 and 32.5 ºc, with relative humidity of 6...
the sub-lethal effect of metarhizium anisopliae and imidacloprid as well as combination of the two control agents was examined on life table parameters of myzus persicae on different cultivars of canola under laboratory condition at 25 ± 1 ºc, 85% rh and photoperiod of 16l: 8d. the offspring resulting from fungus-infested adults were placed onto leaf discs in petri dishes separately to record t...
background and aims: life expectancy is one of the most important indicators of health and well-being of a society. since it is claimed that in aran-bidgol region, center of iran, life expectancy is higher than the average of the country, this study was designed. methods: during a cross-sectional study, population and mortality data of kashan university of medical sciences (kaums) in 2011 were ...
Regarding the importance and high potential of Encarsia formosa Gahan (Hymenoptera: Aphelinidae) for control of the greenhouse whitefly, Trialeurodes vaporariorum Westwood (Homoptera: Aleyrodidae), the effect of different diets and storage of the parasitoid at low temperatures on its longevity and efficiency was studied. The average longevity of the parasitoid on different diets including honey...
Background and Aims: In spite of the advances achieved in the field of dentin adhesives, the longevity of bond to dentin is still a challenge. According to recent studies, Matrix Metaloproteinase (MMP) inhibitors can increase clinical longevity of bonding and decrease leakage. The aim of this study was to evaluate the amount and pattern of doxycycline release from an experimental dentin adhesiv...
introduction the longevity is normally defined as the length of its productive life in the flock, which is the amount of time an animal spends producing (1). longevity reflects the ability of ewe to avoid being culled for low production, low fertility, illness and influences the number and cost of replacements required to maintain the flock size. the benefit of increasing longevity are increase...
Carnation (Dianthus caryophyllus L.) is one of the most important cut flowers in the world. This experiment was carried out to evaluate the effects of pre-harvest application of some amino acids and organic acids on enzymatic traits and longevity of carnation flowers (Dianthus caryophyllus cv. Tessino) based on completely randomized design with 13 treatments and three...

The average longevity of the parasitoid on different diets including honey...
tuberose (polianthus tuberosa) is a commercially important cut flower; but its longevity and quality characteristics are compromised by stress during storage and transportation. thus, it is important to determine the most appropriate preservative solution to best maintained cut flowers. tests were done to examine the effects on of nano-silver (ns) (0, 15, 30 and 45 mg l-1) and sucrose (0, 4 and...
