Abstract
The brown marmorated stink bug (Halyomorpha halys (Stål, 1855) is an invasive species that has entered Europe and has quickly managed to spread to most European countries. In Bulgaria, it was reported in 2016, and today it is widespread throughout the country. It is a polyphagous species that attacks many agricultural crops. This study aimed to investigate the biological parameters of the pest, which will contribute to the implementation of the right plant protection measures. For the climatic conditions of Bulgaria, H. halys develops only one generation per year. The results showed that the embryonic development was completed in 5.68 ± 1.24 days; the first nymphal instar – in 5.17 ± 0.38 days; the second – in 6.95 ± 1.68 days; the third – in 19.03 ± 3.74 days; the fourth – in 17.18 ± 2.58 days, and the fifth – in 30.7 ± 5.14 days.
