Abstract:
Varroa destructor mites are the main biotic threat to honey bees. Mites entered Uruguay in 1978, but remarkably, for the next 20 years, it was not a significant problem for honey bees. Sequencing partially the mitochondrial cytochrome oxidase I gene and genotyping two hypervariable nuclear loci of mite samples from the 1980s and 1990s showed that these correspond to the Korean haplotype and did not differ from current mite samples. These results contribute to the discussion on the spread of V. destructor in South America and its increased virulence in Uruguay.

Sampling Methods: Sample Types
Solid samples include a variety of substances, such as sediments from water bodies, soil, metals, and biological tissues. Two standard methods for extracting sediments from water bodies are grab sampling and piston coring. Grab sampling involves using a device to collect a discrete sediment sample from the bottom of a water body with minimal disturbance. Grab samples do not always represent the entire area due to...
