The sensory ecology of predator detection by prey has been little studied for any arthropod prey predator system, in contrast to the sensory ecology of prey finding by predators. The aim of this study was to quantify the foraging signals produced by the parasitoid Sympiesis sericeicornis (Hymenoptera: Eulophidae) and the sensory ecology of enemy detection and the avoidance behaviour of the leaf...

Information technology has had a significant impact on business operations and allowed the emergence of new business models. These IT-enabled processes and businesses however depend on secure information systems which need to be managed. The management of information systems security (ISS) is a highly dynamic and complex task due to constant change in the information technology domain. In this ...

Remote operations are commonly employed in oil and gas installations in the North Sea and elsewhere. The use of information and communications technologies (ICT) has resulted in process control systems being connected to corporate networks as well as the Internet. In addition, multiple companies, functioning as a virtual organization, are involved in operations and management. The increased con...

It is imperative for organizations to use Information Security Management System (ISMS) to effectively manage their information assets. ISMS starts with a set of policies that dictate the usage of computer resources. It starts with the “21 essential security controls” of ISO 27001, which give the basic standard requirements of information security management. Our research is concerned with the ...

The Myxozoa Grassé, 1970 infecting fish is an important pathogenic group having a worldwide distribution. Among these parasites the monotypic genus Meglitschia Kovaleva, 1988 has been reported infecting the gallbladder (Gb) of a marine fish from the New Zealand fauna [1,2] and a freshwater fish from Brazil, collected in a tributary of Amazon River [3]. The teleostean host (Eugerres brasilianus)...

The dispersal characteristics of a biological control agent can have direct implications on the ability of that agent to control populations of a target host. Tetrastichus planipennisi Yang (Hymenoptera: Eulophidae) is a parasitic wasp native to eastern Asia that has been introduced into the United States as part of a classical biological control program against the emerald ash borer Agrilus pl...

While investigating the parasites of several marine fishes from the Western Atlantic, the Southern Gulf of Mexico and Central America (Panama), the following monogenoidean species from the gills of gerreid fishes (Gerreidae) were found: Diplec-tanum gatunense sp. n. (Diplectanidae) and Octouncuhaptor eugerrei gen. et sp. n. (Dactylogyridae) in Eugerres brasilianus (Cuvier) from Gatun Lake in th...

Under field conditions, species displacements have occurred in different directions between the same invasive species of leafminers (Diptera: Agromyzidae). Liriomyza sativae (Blanchard) was displaced by L. trifolii (Burgess) in the western United States, with evidence suggesting that lower insecticide susceptibility of L. trifolii is a factor. However, in Japan, the opposite has occurred, as L....
