Predicting and controlling infectious disease epidemics is a major challenge facing the management of agriculture, human and wildlife health. Co-evolutionarily derived patterns of local adaptation among pathogen populations have the potential to generate variation in disease epidemiology; however, studies of local adaptation in disease systems have mostly focused on interactions between competi...
Effects of temperature and precipitation on the temporal patterns of dispersing tobacco thrips, Frankliniella fusca, and onion thrips, Thrips tabaci, caught on yellow sticky traps were estimated in central and eastern North Carolina and eastern Virginia from 1997 through 2001. The impact that these environmental factors had on numbers of F. fusca and T. tabaci caught on sticky traps during Apri...
Seasonal flight activity of thrips was examined in commercial tomato fields, Lycopersicon esculentum L., on Virginia’s (USA) Eastern Shore in 2000 and 2001. In each of three regions along the Shore, populations of adult thrips infesting tomato flowers and dispersing within tomato fields were monitored weekly. Frankliniella fusca (Hinds) was the only thrips species captured that is currently con...
On New Guinea and its surrounding islands, an assortment of Carlia with weakly tricarinate to smooth dorsal scales has been variously recognized as C. fusca or members of ûic fusca group. The C. fusca group has never been defined or characterized explicitly, nor has any other group of Carlia. A preliminary cladistic analysis of the Australian, New Guiñean, and Sundan Carlia failed to identify s...
Changes in the natural behavior, expressing adaptation to cohabitation in a community, were observed in the slave-making ants P. rufescens and the slave-species F. fusca and F. cinerea. After a few raids, the initially undirected arousal evoked in the slaves by the amazons' raids, begins to acquire attributes appropriate to the situation, but completely different in both studied slave-species. ...
Motivation, especially on the relationship of remuneration of government doctors to it, has long been an issue of concern. This study sought to elucidate the demotivating factors in service and the perceived discrepancy in income. It was conducted amongst doctors serving in the Ministry of Health, Negeri Sembilan, using self-administered questionnaires. Factors considered demotivating were remu...
Flavonoid, pterocarpans and steroid from Erythrina fusca Lour. growing in Bangladesh: isolation, antimicrobial free-radical scavenging activity
Uromyces phaseoli, the causal agent of bean rust, suppressed shoot and root growth of three bean cultivars, reducing root weight more than shoot weight. The greatest suppression of root weight was on the cultivar that appeared most susceptible by visual ratings of shoot symptoms. Meloidogyne incognita suppressed shoot and root growth of all test cultivars; root weight reductions differed among ...
The incidence of hop powdery mildew on leaves, caused by Podosphaera macularis, collected from 1,606 transects in 77 commercial hop yards in Oregon and Washington over 9 years was used to assess variability in heterogeneity of disease and the estimated binary power law parameters. Spatial analyses of data sets were conducted at the level of individual rows (row level) and multiple rows within a...
The practices of conventional methods for maintenance management in Malaysian Polytechnic faced many issues due to poor service delivery, inadequate finance, poor maintenance plan and maintenance backlogs. The purpose of this study is to improve the conventional method practices which tend to be ineffective in Malaysian Polytechnic. The case studies were conducted with eight Polytechnics from f...
