(Hemiptera: Pentatomidae) Genetic Diversity in North America and Europe.

The brown marmorated stink bug, (Hemiptera: Pentatomidae), is an invasive species in North America and Europe that damages many different host plants. Substantial work has been conducted on the genetic diversity and invasion pathways of in some of the countries where it has been found, based on mitochondrial sequences. The main objective of the present study was to further explore the genetic diversity of invasive populations of exploiting both mitochondrial and nuclear markers.

Polar tube protein gene diversity among Nosema ceranae strains derived from a Greek honey bee health study.

Honey bee samples from 54 apiaries originating from 37 geographic locations of Greece were screened for Nosema apis and Nosema ceranae. Furthermore 15 samples coming from 12 geographic locations were screened also for Paenibacilluslarvae and Melissococcus plutonius and seven honey bee virus species, for the first time on a nation-wide level. There was a tendency in finding proportionally higher spore counts in samples from apiaries that suffered important colony losses.
