life table parameters of the beet armyworm, spodoptera exigua (hã¼bner), on four sugar beet cultivars (renger, fd0005, dorothea and shirin) were studied in laboratory at 27 â± 1â°c, 60 â± 5% rh and a photoperiod of 16l: 8d hours. the larvae successfully developed on all cultivars. the shortest and longest total developmental time were recorded on fd0005 and renger, respectively. the development...

abstract: colorado potato beetle (cpb), leptinotarsa decemlineata (say),is the most important insect pest of potato in iran. if local potato varieties vary in susceptibility to the pest, host plant resistance may provide management benefits to potato growers. a life table study was carried out to determine the relative suitability of four common potato varieties (agria, marfona, savalan and sat...

the life table parameters of macrosiphum rosae l. (hemiptera: aphididae) on five vermicompost-tea (tea-compost) concentrations (20, 40, 60, 80 and 100%) and control treatment (0%) on rosa hybrida l. were determined under laboratory conditions. there were significant differences among pre-imaginal period and adult longevity of the aphid on the five teacompost concentrations. the highest mortalit...

There are several situations in which one can obtain estimates of life-table probabilities of survivorship, I(%), but in which one would still want to smooth' these estimates with reference to a model life table. For example, one could calculate a life table directly by converting observed ,m, values into , q, and hence into l(x) values. In other instances, the I (x ) values available may not d...

Prospective life tables depend on forecasting age-specific mortality. Considerable attention has 2 been paid to methods for forecasting mortality in recent years. Much of this work has grown 3 out of the seminal Lee-Carter method (Lee & Carter 1992). Other extrapolative approaches 4 use Bayesian modelling, generalized linear modelling and state-space approaches. Methods for 5 forecasting mortal...

today, health-related quality of life (hrqol) is an important indicator of development; however, due to the greater vulnerability, hrqol level of women is lower than men, especially in rural regions. this problem has doubled the necessity to investigate and identify the factors affecting hrqol. given the importance of the issue, the purpose of this descriptive- correlative research was to study...

Background, purpose and use of the evaluation The UN Women (UNW), grounded in the vision of equality enshrined in the Charter of the United Nations, works for the elimination of discrimination against women and girls; the empowerment of women; and the achievement of equa...

Since 2002, West Nile virus (WNV) has been detected every year in Houston and the surrounding Harris County, Texas. In 2014, the largest WNV outbreak to date occurred, comprising 139 cases and causing 2 deaths. Additionally, 1,286 WNV-positive mosquito pools were confirmed, the most reported in a single mosquito season.
