The paper evaluates the use of auxiliary insects, the parasitoid wasp Trichogramma evanescens, to counter an infestation of clothes moths Tineola bisselliella in the reserves of the Geneva Ethnographic Museum. After two seasons of deployment of the auxiliaries and monitoring of pest numbers using pheromone traps it was concluded that the parasitoids failed to be efficient because of their limited mobility. Also, the distribution of auxiliary insects made a major cleaning campaign necessary to remove the dead parasitoids from the entire collection involved. The infestation was finally ended by traditional means of hygiene, thorough inspection of the objects, and anoxic treatment. [ABSTRACT FROM AUTHOR]

Various factors oblige today's parents to entrust their children to a child-care worker (CCW), providing services in the domestic sphere, either at the child's parental house or at the day-care worker's (DCW's) own home. Taking this into account, this paper examines job offers and applications for DCWs published in a regional Swiss newspaper as well as other job offers and applications published on a website called bestnounou.ch. The parents often tend to use a variety of terms, which do not point to the child-caring or rearing activity itself, but rather emphasise sociological characteristics of the CCW (age, gender, civil status), requesting, for example, a 'lady', a 'grandmother', a 'student'. Thereby, the parents present the child-care work as: (1) a secondary and temporary activity in relation to another major stable activity (motherhood, apprenticeship, retirement); and (2) an activity that does not require professional skills but inborn aptitudes. Moreover, employers use as synonyms distinctive terms, which refer to various categories of CCW and domestic workers, whose schedules of conditions and salaries are regulated and differ. The parents' inclination to use terms designating the most precarious and underpaid CCW underscores the importance of child-care in the domestic sphere. It leads also to a public image of child-care workers as being a fragmented, unstable, little qualified and economically inconsistent workforce, in contrast to the stable and structural need for their specific services, allowing parents to face their familial and professional responsibilities.
