Other claims from this paper (19)
- Observation Banana weevils cause annual yield losses of 25–75%.
- Mechanism Larval feeding on banana rhizomes reduces water and nutrient uptake and plant stability.
- Intervention effect Weevil and methyl jasmonate treatments induced higher lignin and suberin deposits and cellular modifications in Km5 than Mbwazirume.
- Intervention effect The treatments induced high total phenolic content and antioxidant capacity in Km5 relative to Mbwazirume.
- Association Induced polyphenols were associated with less than 5% weevil damage in Km5, versus 11% in Mbwazirume.
- Intervention effect One application of 0.01% methyl jasmonate reduced Mbwazirume weevil damage by 50% against untreated control.
- Intervention effect Clove extract and analogs had an egg inhibitory dose of 0.08 to 0.22%.
- Observation Black pepper had an egg inhibitory dose of 0.24 to 0.75%.
- Intervention effect Half the clove egg inhibitory dose caused 50% larval mortality.
- Intervention effect Pepper repelled 80–98% of adult weevils within 6–48 hours.
- Intervention effect Clove repelled 78–90% of adult weevils within 6–48 hours.
- Intervention effect Neem repelled 63–75% of adult weevils within 6–48 hours.
- Intervention effect Curvularia senegalensis inhibited 75 to 90% of weevil egg hatch.
- Intervention effect Fusarium verticillioides inhibited 75 to 90% of weevil egg hatch.
- Intervention effect Beauveria bassiana and FOSC inhibited 25 to 55% of weevil egg hatch.
- Intervention effect Fungal treatment 14 days before weevils increased banana SPAD values significantly.
- Intervention effect Fungus-treated plants had less than 20% rhizome damage.
- Intervention effect Curvularia senegalensis reduced rhizome damage most, followed by Beauveria bassiana and Fusarium verticillioides.
- Recommendation The authors recommend combining host resistance, local botanical extracts, and entomogenous fungi to manage banana weevils.
