The parasitoid assemblage associated with a lepidopteran leafminer, Coptotriche japoniella (Tischeriidae), on an evergreen tree, Eurya japonica (Theaceae), was studied in the center of Japan to explore parasitoid coexistence mechanisms. The leafminer supported 12 parasitoid species. Eight abundant or common species were classiÞed into Þve guilds according to their koinobiont/ idiobiont mode and...
The pea leafminer, Liriomyza huidobrensis (Blanchard) (Diptera: Agromyzidae), is an important pest of leafy greens in the Holland Marsh, Bradford, Ontario, and was Þrst discovered in this area in 1998. A 2-yr study was undertaken to document the parasitoid complex of this recent addition to leafminer guild in Ontario and examine endoparasitoids reared from pea leafminer pupae collected from eig...
A rationale and a method are presented for estimating the prevalence of mental retardation in individual catchment areas. The method incorporates the adaptive behavior criterion of the AAMD definition of mental retardation and proposes prevalence rates based on chronological age and degree of impairment. Special focus is given to the population with moderate to profound mental retardation. a me...

The most important pests of acacia black locust (Robinia pseudoacacia L.) (Fabaceae) are: Appendiseta robiniae Gillette, Phyllonorycter robiniella Clemens, Parectopa Nematus tibialis Newman and Obolodiplosis Haldemann, species from North America, where it also originates the acacia, which is host plant.

We studied two species of neotropical parasitoids that occur naturally in northeastern Brazil and are associated with Liriomyza sativae (Blanchard): Opius (Gastrosema) scabriventris Nixon (Hymenoptera: Braconidae) and Chrysocharis vonones (Walker) (Hymenoptera: Eulophidae). We evaluated the influence of seven temperatures on the duration of the egg-adult period and on the survivorship of the im...
Recently, service area has been emerging field of robotic applications. Even though assis tant robots play an important role for the disabled and the elderly, they still suffer from operating the robots using conventional interface devices such as joysticks or keyboards. In this paper we propose an efficient computer interface using real-time eye-gaze tracking system. The inputs to the proposed...
