BACKGROUNDThis study was aimed at assessing the fumigant toxicity to adult Thrips palmi (a serious insect pest) and Orius strigicollis (a beneficial predator insect) of basil (Ocimum basilicum) essential oil compounds and structurally related compounds using vapour‐phase toxicity bioassays.
RESULTSAgainst adult T. palmi, linalool (LD50 0.0055 mg cm−3) was the most toxic fumigant and was 15.2‐fold...
BACKGROUND: The contact + fumigant toxicity of 92 plant essential oils and control efficacy of 18 experimental spray formulations containing nine selected essential oils (0.5 and 0.1% sprays) and six commercial insecticides to females from B‐ and Q‐biotypes of Bemisia tabaci were evaluated using vapour‐phase mortality and spray bioassays.
RESULTS: Garlic and oregano (LC50, 0.15 mL cm−3) were the most...
