Situation of Helicoverpa armigera in Hungary
The cotton bollworm, Helicoverpa armigera (EPPO A2 quarantine pest) was recorded as a cotton pest in Hungary in 1951, and became a more and more regular immigrant into the Carpathian Basin. It has been reported as a regular pest since 1986 on maize, tobacco and since 1993 on paprika. Under Hungarian conditions, sporadic populations develop but cannot survive in winter, so the damage is normally limited. In 1993, Helicoverpa armigera occurred in unusually high numbers and caused some damage to maize, tobacco, vegetables and ornamentals. It is thought that adults of this species flew in two waves in June and July from the south-west towards the Carpathian Basin. However, no development stage has been able to survive to winter frost. The Hungarian Plant Protection Service will continue to monitor this pest during the next growing seasons.
