Mr Dudeney, from Brighton, says he has had more calls from parents whose children want to compete.
“We have had a steady interest in youth players joining Sussex Youth Darts but in the last 12 months that has increased four-fold,” Mr Dudeney said.
“This is because of the incredible run Luke Littler had in last year’s World Championships and what he has achieved since.
His team regularly competes at under-18 and under-21 level against sides from across the South, including Kent, Surrey, Essex, Berkshire and London.
“Thanks to Luke it has brought a breath of fresh air into the game, and a new younger audience,” he said.
Mr Dudeney’s 20 year-old son, Tavis Dudeney, represents Sussex Youth and England and has competed against Luke Littler.
