Other claims from this paper (19)
- Intervention effect Manuka essential oil and one of its four fractions (fraction 2) were toxic to the two lepidopteran pests.
- Intervention effect Fraction 2 was more toxic than the whole manuka essential oil.
- Observation Gas chromatography-mass spectrometry showed leptospermone, isoleptospermone and flavesone to be the major components of manuka fraction 2.
- Intervention effect Leptospermone, isoleptospermone and grandiflorone were more toxic to both caterpillar species than the whole essential oil.
- Observation The median lethal dose of manuka essential oil against T. ni larvae was 50 ug/larva.
- Observation The median lethal dose of fraction 2 against T. ni larvae was 25 ug/larva.
- Observation The median lethal dose of leptospermone against T. ni larvae was 20 ug/larva.
- Observation The median lethal dose of isoleptospermone against T. ni larvae was 20 ug/larva.
- Observation The median lethal dose of flavesone against T. ni larvae was 45 ug/larva.
- Observation The median lethal dose of grandiflorone against T. ni larvae was 18 ug/larva.
- Observation The median lethal dose of manuka essential oil against C. includens larvae was 42 ug/larva.
- Observation The median lethal dose of fraction 2 against C. includens larvae was 32 ug/larva.
- Observation The median lethal dose of leptospermone against C. includens larvae was 28 ug/larva.
- Observation The median lethal dose of isoleptospermone against C. includens larvae was 20 ug/larva.
- Observation The median lethal dose of flavesone against C. includens larvae was 41 ug/larva.
- Observation The median lethal dose of grandiflorone against C. includens larvae was 14 ug/larva.
- Intervention effect Manuka essential oil and its constituents were phytotoxic to cabbage, soybean and corn.
- Observation Cabbage and corn were the most and the least affected plants by manuka essential oil and its constituents, respectively.
- Recommendation The authors conclude manuka essential oil and its components are promising biopesticides, but improved delivery systems are needed to reduce phytotoxicity.
