The main characteristics of 55 nests of Protopolybia exigua exigua were periodically evaluated in Ribeirão Preto, southeastern Brazil. Although the queens' life-span can eventually reach one year, nests barely thrive for six months because most of them are periodically invaded by the scavenger phorid fly, Megaselia aff. picta. Under heavy infestation the adult wasp population partially closes the nest entrance, migrates and constructs a new nest in the neighborhood. Afterwards the old-nest's entrance can be completely closed by the wasps which results in blocking the parasitoid flies inside. In the tropics, predation by ants is considered the main selective pressure which shaped most of the bionomic characteristics of Polistinae wasps. It is suggested that Megaselia can easily overcome the usual wasps defensive tactics just because they are so specialized against ants. Aerial raids, fast erratic-jerking movements, rapid and efficient oviposition behavior, etc. can eventually turn Megaselia into a very important enemy of some social wasps.

We report the use of an Internet-based videophone to support a child undergoing bone marrow transplantation (BMT). Over the Christmas period, an eight-year-old boy with an underlying diagnosis of attention-deficit/hyperactivity disorder (ADHD) and a history of absconding and aggressive non-compliant behaviour was treated by BMT. We installed an Internet-based videophone in the patient's hospital room two days post-transplant. A second videophone was installed in the patient's home and used the existing home telephone line. In all, 14 videophone calls were made over a nine-day period. The videophone improved interfamily social and emotional support, and appeared to reduce some of the inherent anxiety and distress resulting from paediatric bone marrow transplantation.
