BioPerminutus- (Coccidoxenoides perminutus) parasitoid for the control of the Citrus mealybug and the Grape mealybug.
Unit of packaing
- BioPerminutus is packaged in boxes containing mummified mealybugs which inhabit pupae of the parasitoid. Each box contains 3000+ BioPerminutus individuals or 1000+ individuals.
- Target pest: Citrus mealybug (Planococcus citri) or Vine mealybug (Planococcus ficus). Female adults are black in colour with noticeable translucent wings, size ± 3mm long. Early stages: develop inside the host.
- Adult wasps will emerge from the mummies within one to three days depending upon the ambient temperature and the age of the pupa within the mummy). Immediately upon emergence, the wasps will mate and then will begin searching for a host suitable for parasitization, ie. first and second instar larvae.
- Female adult wasps are black in colour with noticeable translucent wings, size ± 3mm long.
Direction for use
- Puncture the sticker in the centre of the box exposing the exit hole.
- Place a marker on the edge of a row so that you can locate the release site at a later date.
- Heavy rain and strong wind hinder the population build-up of the parasitic wasp. Place the package in a shady place, protected from rain or dew, preferably close to a mealybug-infested spot. Following their emergence, the wasps will fly out of the package and disperse in between the plants. Do not sprinkle the mummies actively from the container.
- Once parasitic wasps begin to emerge, they will be attracted to the exit hole by sunlight.
- Place the box in a way that will prevent ants from getting inside. As a rule, if ants are present at the mealybug hotspots, they must be treated by selective treatment of ant nests or by application of ant baits/barriers on the tree trunk. Ants encourage honeydew secretion by the mealybugs, transfer them from one place to another and protect them by actively interfering with the parasitoid.
Contra Indications and Environmental conditions
- Do not touch the mummies inside the box.
- Reduce ant performance.
- BioPerminutus is susceptible (to a certain degree) to the common pesticides that are used to control other pests in the crop. Therefore, before applying any pesticide, the user should consult BioBee’s field advisors and ask for updated information concerning side effects of pesticides on BioPerminutus.
- Regular foliar applications can affect performance of BioPerminutus.
Storage and handling
- Maximum storage after receipt of product: 1-3 days.
- Storage temperature: 20 – 26˚C.
- In an office or similar building, preferably in the dark.
- Do not store inside a chemical store.
- The empty yellowish khaki coloured mummies will remain in the matchbox after hatching. Inspection after 2 weeks reveals the % emergence.
- In the event of a high mealybug population or the occurrence of hotspots, release rates must be increased as directed.
Mode of action
Female adult parasitic wasp parasitizes the 1st to 3rd instar mealybug crawlers eventually killing the mealybug. Second instar stages are preferred, the life cycle is completed and further parasitism of mealybug in the field continues until control of the pest is achieved.
Monitoring and Visual Results
After 2-3 weeks, the first parasitized mealybug can be identified in the orchard/vineyard. Parasitized mealybug turn oval, ± 3mm long and appear yellow to brownish in colour with a leathery texture. The adult parasitic wasp emerges from the pupa through a round hole.
