Some people are just more trusting . <| sep |> Most evidence suggests neonics are not playing a majordirect role in colony losses . In Europe and the U . S . , two distinct phenomena longterm declines in colony numbers and increasing annual colony losses , have led to significant interest in their causes and environmental implications . The most important drivers of a longterm decline in colony numbers appear to be socioeconomic and political pressure on honey production . In contrast , annual colony losses seem to be driven mainly by the spread of introduced pathogens and pests , and management problems due to a longterm intensification of production and the transition from large numbers of small apiaries to fewer , larger operations .
