“…High rates of mortality are tied to the presence of autoinfective spores that facilitate the rapid division and invasion of digestive tissue and affect the regenerative digestive cells (15). These differences can be related to the recently described higher colony losses during the last few years, especially at the end of winter (9,24).…”

A multiplex PCR-based method, in which two small-subunit rRNA regions are simultaneously amplified in a single reaction, was designed for parallel detection of honeybee microsporidians (Nosema apis and Nosema ceranae). Each of two pairs of primers exclusively amplified the 16S rRNA targeted gene of a specific microsporidian. The multiplex PCR assay was useful for specific detection of the two species of microsporidians related to bee nosemosis, not only in purified spores but also in honeybee homogenates and in naturally infected bees. The multiplex PCR assay was also able to detect coinfections by the two species. Screening of bee samples from Spain, Switzerland, France, and Germany using the PCR technique revealed a greater presence of N. ceranae than of N. apis in Europe, although both species are widely distributed.

“…The 2000 harvest was just 30-40% of the 1995-1996 yields and disease remains a major factor. One French national survey noted that 76% of apiaries suffered from at least one serious disease (Faucon et al, 2002). In other countries and in oilseed rape crops, which serve as key pollen and nectar sources for bees at particular times of the year, imidacloprid seed treatments have not been associated with bee declines.…”

Insecticide use: Contexts and ecological consequences

Constraints to the sustainability of insecticide use include effects on human health, agroecosystems (e.g., beneficial insects), the wider environment (e.g., non-target species, landscapes and communities) and the selection of insecticide-resistant traits. It is possible to find examples where insecticides have impacted disastrously on all these variables and others where the hazards posed have been (through accident or design) ameliorated. In this review, we examine what can currently be surmised about the direct and indirect long-term, field impacts of insecticides upon the environment. We detail specific examples, describe current insecticide use patterns, consider the contexts within which insecticide use occurs and discuss the role of regulation and legislation in reducing risk. We consider how insecticide use is changing in response to increasing environmental awareness and inevitably, as we discuss the main constraints to insecticide use, we suggest why they cannot easily be discarded.

“…Several behavioral studies, dealing with sublethal effects of pesticides, have indicated that there might be an important impact of such products on winter mortality (Faucon et al, 2002;Thompson et al, 2007), orientation (Decourtye et al, 2004), homing behavior , locomotor activity (Suchail et al, 2001;El Hassani et al, 2008) and communicative capacity (Haynes, 1988;Medrzycki et al, 2003).…”
