T1 - Nosema maddoxi infecting the brown marmorated Stink bug, Halyomorpha halys (Stål) (Hemiptera: Pentatomidae), in the Republic of Georgia JF - Biocontrol Science and Technology N2 - Halyomorpha halys is an invasive, polyphagous stink bug from Asia, first reported attacking hazelnut orchards in the Republic of Georgia in 2015. A microsporidian pathogen discovered in Georgian H. halys has been identified as Nosema maddoxi by sequencing the ribosomal small subunit gene. Nosema maddoxi is native to North America and has also been found in China and South Korea; in North America it infects native stink bugs and H. halys. Investigations were carried out during different seasons in three regions of West Georgia in 2018–2019. The highest prevalence of N. maddoxi was detected among overwintered adults collected in May in the Guria region.

The damage to hazelnut kernels was evaluated when H. halys adults were allowed to feed on kernels in different stages of development. Furthermore, BMSB adults were allowed to feed on almost ripened fruits of blueberry, on small mandarin fruits which were not yet well developed, and on ripened fruits of mandarin. The evaluation of damage on lemon was recorded after allowing adult BMSB on small, not yet developed fruits and on almost developed fruits. It was shown that hazelnuts are susceptible to damage caused by feeding of BMSB throughout the entire period of kernel development (100% of kernels were damaged and did not develop at all). Furthermore, BMSB damages blueberry severely (100% damage) when the fruits are almost ripened. Damage to mandarin fruits in early development stages was over 90%, and 100% of ripened mandarin fruits dropped to the ground. We did not find any damage when BMSB was allowed to feed on Lemon throughout the development of the fruits.
