Abstract: Previous trials found that dimethyl disulfide (DMDS) showed obvious repellency to Apolygus lucorum adults under laboratory and field conditions. However, this effect only lasted 6 days after spray under field condition. In this study, we screened the slow-release materials, controlled release formulations, diluted concentration of DMDS, and eventually examined the lasting effect of slow-release system in the open field. The results showed that it could keep the slow-release effect of DMDS at least 15 d in the field when we used vial of PE and mineral oil under the dilution of 1: 10. In addition, applying this slow-release system into jujube orchard after 30 d, it reduced 48.0% of the overwintering eggs of A. lucorum within 10 m from the repellent stripe. Our study provided the groundwork for the application of DMDS to control this mirid bug in the field.
