Other claims from this paper (14)
- Observation The highest mean number of B. tabaci adults on potato was 1.13 adults/plant, recorded on November 12, 2022.
- Observation The highest mean number of B. tabaci adults on potato was 1.1 adults/plant, recorded on November 12, 2022.
- Observation The nymph population on potato peaked at 2.21 nymphs/plant on November 19, 2021.
- Observation The nymph population on potato reached 2.413 nymphs/plant in 2022.
- Observation Adult and nymph populations of B. tabaci on potato decreased continuously until December.
- Association The B. tabaci population (nymph and adult) on potato was significantly correlated with wind speed, relative humidity and precipitation in the 2021 season.
- Association The B. tabaci population (nymph and adult) on potato was significantly correlated with all examined environmental factors in the 2022 season, except for precipitation levels.
- Intervention effect The tested essential oil and chitosan emulsions had a slightly lower efficacy than imidacloprid in controlling B. tabaci on potato fields.
- Intervention effect Thyme and citronella oils were the most effective in reducing B. tabaci adult populations on potato, followed by camphor and geranium, compared with imidacloprid as a positive control.
- Intervention effect The highest reduction percentage on potato was caused by thyme combined with chitosan (thyme+Ch).
- Intervention effect The (EOs+Ch) mixture was more effective than the essential oils alone on potato.
- Mechanism Chitosan enhances the durability of essential oil emulsions applied to potato.
- Mechanism Chitosan improves the adherence of essential oil emulsions to leaf surfaces of potato.
- Intervention effect Combining chitosan with thyme or citronella oils enhanced their effectiveness against B. tabaci adults on potato.
