neoseiulus californicus (mcgregor) is a predatory mite that can control spider mites. the effect of seven strawberry cultivars (including: ‘marak’, ‘yalova’, ‘aliso’, ‘gaviota’, ‘sequoia’, ‘camarosa’ and ‘chandler’) on the growth and development of n. californicus was studied in the laboratory conditions (27 ± 1 °c, 70 ± 5% rh and 16l: 8d photoperiod). there was significant difference in the nu...
Small walnut aphid (Chromaphis juglandicola (Kaltenbach) (Hemiptera: Aphididae) is important pest in orchards Lake Van Basin, Turkey. In this study, the life-table parameters reflecting population growth rate and predation of Chrysoperla carnea (Stephen) (Neuroptera: Chrysopidae), which one predators pest, were determined. Life table estimated according to age-stage, two-sex life method. Varian...
BACKGROUND the mortality experience for structured settlement (SS) annuitants issued both standard (Std) and substandard (SStd) has been reported twice previously by the Society of Actuaries (SOA), but the 1995 mortality described here has not previously been published. We describe in detail the 1995 SS mortality, and we also discuss the methodology of calculating life expectancy (e), contrasti...
Life-table analysis consecutive cases of isolated coronary bypass surgery at the Buffalo Hospital between 1973 and 1977 showed an estimated survival of 94 per cent at five years, equal to that of an age- and sex-matched group of the US population. Subsets of these patients divided according to sex, age, number of vessels narrowed, number of segments grafted, history of myocardial infarction, ej...
BACKGROUND Although there is a broad societal interest in socioeconomic differences in survival after an acute myocardial infarction, only a few studies have investigated how such differences relate to the survival in general population groups. We aimed to investigate education-specific survival after acute myocardial infarction and to compare this with the survival of corresponding groups in t...
In a paper published in the previous issue of Population Studies , Zhongwei Zhao questions the uniqueness of a mortality pattern first identified by Goldman (1980) and subsequently redefined by the United Nations (1982). As originally formulated by Goldman, the Far Eastern pattern is characterized by ‘excessively high’ death rates among older men relative to death rates among both younger men a...
