The sterile insect technique (SIT) is a genetic pest management tactic that relies on the release of insects that have been sterilized with ionizing radiation to lower the population reproductive rate. Toward developing an effective PW\u2010SIT program, this study has, for the first time, investigated the effects of gamma irradiation on the sterility and survival of this species.<\/jats:p><\/jats:sec><jats:sec><jats:title>RESULTS<\/jats:title><jats:p>Among the array of doses tested, we found that pupal PW males and females irradiated at 110\u2009Gy produced no adult offspring. Furthermore, females mated with a male irradiated at 110\u2009Gy had high egg sterility (97.3%), and irradiated females nearly completely failed to lay eggs (97.5%). Individuals irradiated at this dose had a shortened lifespan (lethal time to 50% mortality values of 12 and 11\u2009days for males and females, respectively) and quantitatively reduced spontaneous flight activity. The eclosion rate of PW pupae was not significantly reduced by any radiation treatment.<\/jats:p><\/jats:sec><jats:sec><jats:title>CONCLUSION<\/jats:title><jats:p>This study suggests that PWs irradiated at a gamma radiation dose of 110\u2009Gy as pupae could feasibly be used in a PW\u2010SIT program, because both males and females were 100% sterile at this dose. These findings will inform the development of a SIT program that could considerably improve the sustainability and effectiveness of PW management in greenhouse and field pepper crops worldwide. \u00a9 2023 His Majesty the King in Right of Canada and The Authors. <jats:italic>Pest Management Science<\/jats:italic> published by John Wiley &amp; Sons Ltd on behalf of Society of Chemical Industry.
