This study investigated the efficacy of high‐volume spraying with the adulticide α‐cypermethrin alone and in combination with the larvicide diflubenzuron on the density of sand flies in gardens of three detached households in periurban areas in southeast Spain. Treatments were applied four times between June and August 2016, and four nearby sites, two households and two non‐urbanized sites, were untreated controls. The number of sand flies collected between May and October 2016 using sticky interception and light attraction traps, was 4446 specimens. Species identified morphologically included Sergentomyia minuta (n = 2101; 48%), Phlebotomus perniciosus (n = 1922; 44%), Phlebotomus papatasi (n = 173; 4%), Phlebotomus sergenti (n = 161; 4%) and Phlebotomus ariasi (n = 36; 1%). Sand flies were detected in both treated and untreated sites. The proportion of positive sticky traps and the median (range) density of sand flies in positive traps were 61% traps and 7 (2–172) sand flies/m2/day in untreated sites, and 43% traps and 4 (1–56) sand flies/m2/day in treated sites (p < 0.05). Similarly, for light traps, it was 96% traps and 30 (3–168) flies/trap/day, and 83% traps and 3 (1–12) sand flies/trap/day, respectively (p < 0.05). However, sand fly density followed a comparable seasonal pattern in untreated and treated sites and did not consistently decrease following insecticide applications. These results were confirmed with mixed negative binomial modelling of sand fly density adjusted for time since application, month, environmental setting and site. The limited efficacy of the treatments, added to their cost, the impact of insecticides on non‐target organisms and human health, and the risk of development of insecticide resistance, should dissuade similar outdoor applications to control sand fly vector populations in residential areas.

This research is based on the assumption that in order to improve the quality of life of children with major health problems in the early stage of their life, especially in the case of disability, it is necessary to ensure the continuity and proper two-way integration of early childhood educational planning and health care, both provided by the adults involved, that is parents and professionals. Therefore, we tried to explore and piece together the complex set of family support experiences, both in the process of forming an attachment and affiliation to the newborn and in the construction of a common evolutionary history, aimed at the well-being of the entire family unit. We considered the context and actors of the first few days and months in the lives of children with a difficult life course, in a city of Northern Italy. By means of qualitative investigation, we carried out observations in the neonatal intensive care units of hospitals over a period of 10 months. Our observations continued in the local healthcare, social, and educational services, entrusted with providing care to children and support to parents after hospital discharge. We also carried out observations in nursery schools, in order to highlight early forms of individualised educational planning, drawn up by the educators together with the family.
