(known as painted bug) is a pest native to India, Southeast Asia, and middle and central Africa and was reported as invasive in the southwestern USA, Hawaii, Mexico, South America, and two Mediterranean islands. The feeding activity results in extensive damage to economically important Brassicaceae crops. Among sustainable alternatives to synthetic pesticides, the Sterile Insect Technique (SIT) is considered a promising strategy because it relies on the release of competitive sterile males that can reduce the pest reproduction. In this study, the efficacy of different doses of gamma irradiation (60, 80, and 100 Gy) was evaluated to identify the treatment that would ensure high sterility without compromising the competitiveness of the treated males. Observational tests showed that the doses of 60 Gy and 80 Gy showed no difference in mating times compared to non-irradiated males, in contrast to 100 Gy. Thus, 80 Gy was identified as the most promising dose. For further investigation, tests were conducted under choice and no-choice conditions at 80 Gy for three days. The results showed that irradiated males had a comprehensive higher mating rate than non-irradiated males, and under choice conditions, they were often preferred by females, confirming that SIT has potential as an environment-friendly method for controlling .
（又称彩绘蝽）是一种原产于印度、东南亚以及非洲中部和中部地区的害虫，据报道它已入侵美国西南部、夏威夷、墨西哥、南美洲以及两个地中海岛屿。其取食活动会对经济上重要的十字花科作物造成广泛损害。在合成农药的可持续替代方法中，不育昆虫技术（SIT）被认为是一种有前景的策略，因为它依赖于释放有竞争力的不育雄虫来减少害虫繁殖。在本研究中，评估了不同剂量（60、80和100戈瑞）的伽马辐射的效果，以确定能确保高不育率且不影响处理后雄虫竞争力的处理方法。观察测试表明，与未辐照雄虫相比，60戈瑞和80戈瑞剂量的雄虫在交配时间上没有差异，而100戈瑞剂量的雄虫则不同。因此，80戈瑞被确定为最有前景的剂量。为了进一步研究，在80戈瑞剂量下进行了三天的选择和无选择条件测试。结果表明，辐照雄虫的交配率总体上高于未辐照雄虫，并且在选择条件下，雌虫通常更喜欢它们，这证实了不育昆虫技术作为一种控制……的环保方法具有潜力。 （原文中最后“controlling”后似乎缺失了具体害虫名称）
