Release of parasitic wasps (Hymenoptera: Pteromalidae) as biological control agents for house flies and stable flies in livestock confinements has had variable success. In part, this may reflect a lack of knowledge regarding the optimal distance to be used between parasitoid release stations. In the current study, we assessed the effect of linear distance on host parasitism by the wasp Spalangi...

The ultimate goal of nesting is the production of young and therefore predation and brood parasitism may constrain reproductive success. Breeding azurewinged magpies (Cyanopica cyanus) were exposed to mounts of an sparrowhawk (Accipiter nisus) (i.e. an avian predator on adult and fledged chicks), a female great spotted cuckoo (Clamator glandarius) (i.e. a brood parasite that also preys on eggs ...

The population phenology of Asian citrus psyllid, Diaphorina citri Kuwayama, was monitored weekly for 110 wk on two species of Citrus, kinnow mandarin and sweet orange, at two different research sites in Faisalabad, Punjab Pakistan. Citrus flush growth patterns were monitored and natural enemy surveys were conducted weekly. Flush patterns were similar for kinnow and sweet orange. However, flush...

Endoparasitoids in the order Hymenoptera are natural enemies of several herbivorous insect pest species. During oviposition they inject a mixture of factors, which include venom, into the host, ensuring the successful parasitism and the development of their progeny. Although these parasitoid factors are known to be responsible for host manipulation, such as immune system suppression, little is ...

The spectacular corporate collapses over the past decade, along with the introduction of the Sarbanes-Oxley Act and similar legislations across the world, have promoted significant awareness of IT governance. However, the causes of success and failure in IT governance framework adoption are yet to be adequately studied. This study aims to address this deficiency by proposing a research model to...

The importance of user acceptance of technology is critical for the success of technology implementation in the health-care sector. Spending on the procurement of new technology is growing in the hope of improving patient care as well as providing better services to the public, thus it is important that the technology is used to achieve its intended purpose. Success or failure of technology imp...

Ten years ago, we presented the DeLone and McLean Information Systems (IS) Success Model as a framework and model for measuring the complexdependent variable in IS research. In this paper, we discuss many of the important IS success research contributions of the last decade, focusing especially on research efforts that apply, validate, challenge, and propose enhancements to our original model. ...
