The mass rearing of parasitoids represents a fundamental stage for programmes of biological control. The progeny of the parasitoid Palmistichus elaeisis Delvare and LaSalle (Hymenoptera: Eulophidae) were evaluated on previously refrigerated pupae of Bombyx mori L. (Lepidoptera: Bombycidae). Forty-eight to 72 hours-old pupae of B. mori were stored at 10 degrees C for five, 10, 15 or 20 days and ...
Recent attention has focused on the harmful effects of introduced biological control agents on nontarget species. The parasitoid Compsilura concinnata is a notable example of such biological control gone wrong. Introduced in 1906 primarily for control of gypsy moth, Lymantria dispar, this tachinid fly now attacks more than 180 species of native Lepidoptera in North America. While it did not pre...
Autoparasitoids, an important class of intraguild predators used in classical biological control, have a unique biology. Females develop as primary endoparasitoids of scale insects and whiteflies. Males develop at the expense of conspecific or heterospecific parasitoid prepupae. To evaluate the effect of autoparasitism on host suppression, system stability, and parasitoid coexistence, stage-str...
Most of the unknown biological diversity of macro-organisms remaining to be discovered and described lies in the tropical regions of the world and consists primarily of insects. Those insects with parasitoid lifestyles constitute a significant portion of insect diversity, yet parasitoids are among the most poorly known of major insect guilds in the humid tropics. Here we describe and analyze th...
background: although leprosy is an endemic disease in iran, it has been reduced rate over recent years. the present study has been conducted to investigate epidemiology of incident cases over last 6 years. methods: a descriptive study designed to investigate all reported cases of leprosy in kermanshah province from 2003-2008. data was collected from leprosy referral center in kermanshah. data w...
Welcome to REFS 2008, the 2nd IEEE International Workshop on Requirements Engineering For Services. On behalf of the programme committee, we welcome you to Turku, Finland. The REFS 2008 workshop serve as a highly interactive forum for in-depth discussion of all issues related to requirements engineering for services following the REFS 2007 workshop in Beijing, China. Service orientation is rapi...
The Thinking Head project has as it aims to develop (i) a new generation Talking Thinking Head that embodies human attributes, and improves human-machine interaction; and (ii) a plug-and-play research platform for users to test software in an interactive real-time environment. Here, project progress is discussed in terms of the four teams: 1. Head Building – (i) Plug-and-Play architecture, (ii)...
