- Intervention effect Frass extract from S. littoralis larvae fed a semi-artificial diet (4th, 5th and 6th instars) gave a complete oviposition deterrent effect against P. operculella.
- Intervention effect Frass extract from A. ipsilon larvae fed a semi-artificial diet (1st-3rd and 6th instars) gave a complete oviposition deterrent effect against P. operculella.
- Intervention effect When larvae fed on castor oil leaves, only frass extract of A. ipsilon 6th instar larvae gave the same complete oviposition deterrent effect.
- Mechanism Low amounts of phenols and flavonoids in the water extract of A. ipsilon larval frass resulted in relatively more oviposition deterrent effect on fertile females.
- Intervention effect In semi-field experiments the reduction of laid eggs reached 100 percent after two days with frass extracts of 4th and 5th instar S. littoralis and 6th instar A. ipsilon larvae.
- Intervention effect Laid eggs were reduced by 48.95 percent after 30 days in untreated sacks placed between treated sacks, relative to isolated control.
