Physiol."],"abstract":"<jats:p>The sterile insect technique (SIT) is widely used to control Lepidopteran pests by inducing inherited sterility. The noctuid moth <jats:italic>Xestia c-nigrum<\/jats:italic> is a polyphagous pest whose subterranean larvae severely injure cereals and some vegetables. The goals of this study were to assess the impact of X-ray irradiation on the development and survival of <jats:italic>X. c-nigrum<\/jats:italic> and use the data to select suitable sterilizing doses for potential future use in pest management. Batches of male pupae were exposed to 0 (control), 10, 30, 50, 100, 200, 300, or 400\u00a0Gy of X-rays, approximately 24\u00a0h before adult emergence. Exposure of late-stage pupae to 10\u2013200\u00a0Gy of radiation had no significant effect on adult emergence, but all doses (10\u2013400\u00a0Gy) reduced adult longevity, the number of spermatophores in mated females, and the number of eggs laid per female in the irradiated parental generation compared with the controls. Exposure to 10 and 30\u00a0Gy had no significant effects in the F1 generation on 1) the rate of egg hatch, 2) the duration of larval or pupal development, or 3) adult longevity. However, exposure to 50\u00a0Gy reduced the rate of egg hatch in the F1 generation, and when male pupae were exposed to 100\u00a0Gy only 1% of the F1 eggs hatched. Also at 100\u00a0Gy, the developmental durations of larvae and pupae were significantly prolonged, and longevity of adult moths was reduced. There were no significant differences between the control group and any treatments in 1) the sex ratio of the F1 adults, 2) the duration of F1 pre-oviposition or oviposition periods, or 3) the number of eggs laid per F1 female. Our findings indicate that a dose of 100\u00a0Gy can effectively slow pest development and reduce larval survival in the F1 generation. In addition, F1 adults from lines treated with 100\u00a0Gy were able to mate and lay eggs, but all F2 eggs failed to hatch. Our results suggest that use of X-ray irradiation has potential to control this polyphagous pest at the regional level.<\/jats:p>","DOI":"10.3389\/fphys.2024.1362991","type":"journal-article","created":{"date-parts":[[2024,2,21]],"date-time":"2024-02-21T04:50:07Z","timestamp":1708491007000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":5,"title":["Effect of X-ray irradiation on the biological parameters of Xestia c-nigrum"],"prefix":"10.3389","volume":"15","author":[{"given":"Shijiao","family":"Chu","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bing","family":"Liu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Huan","family":"Li","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Keke","family":"Lu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yanhui","family":"Lu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2024,2,21]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"148","DOI":"10.1016\/j.radphyschem.2016.08.012","article-title":"Effects of X-ray irradiation on different stages of Sesamia nonagrioides Lefebvre (Lepidoptera: noctuidae) and DNA damage","volume":"130","author":"Aksoy","year":"2017","journal-title":"Radiat.
