The competition was initially scheduled from 22 to 27 September this year. The World Championships will now take place in the second half of 2021 with the exact dates to be confirmed.
The decision to postpone the competition was made by the Lonato Local Organising Committee and World Shooting Para Sport due to the COVID-19 pandemic.
Lonato will be the second edition of the Para Trap World Championships.
The Italian city hosted the inaugural competition in October 2018, with 57 athletes from 14 countries in action at the Trap Concaverde venue.
Hosts Italy topped the standings with five medals and was the only country to have shooters on the podium in all three classes.
Australia's Scottie Brydon, Finland's Vesa Jarvinen and Italy's Francesco Nespeca were crowned the first Para trap world champions.
Para trap was also part of the competition programme of the Sydney 2019 World Shooting Para Sport Championships in Australia.
Para trap has seen excellent growth in recent years with 23 countries now actively participating in competitions, and World Shooting Para Sports looks forward to another important step forward in the development of the sport in Lonato next year.
