Real PermiFIX

Coccidoxenoides perminutus
Real PermiFIX (Coccidoxenoides perminutus) are extremely effective parasites of Citrus & Vine mealybug and provide control of both low- & high-density infestations. Real perminutus are black in colour with noticeable translucent wings, long antennae & are approximately 2mm in length. It is important to determine the type of mealybug present before considering the use of Real perminutus since the parasite is not very effective against species other than Citrus & Vine mealybug.
Mode of Action

Host Range/ Effective against:

  • Vine Mealybug (Planococcus ficus)
  • Citrus mealybug (Planococcus citri)
  • Citrophilous mealybug (Pseudococcus calceolariae)

Real PermiFIX

  • Poses no threat to non-target insects
  • Serves as a supplement to naturally occurring enemies of mealybug (Real ChrysoFIX, Real CryptoFIX etc.)
  • Corrective chemical treatments can be avoided
  • No chemical residues – thus no market restrictions
  • They contribute to resistance management – mealybugs are not able to develop resistance against parasite attack.

Real PermiFIX are best introduced in spring/early summer, when the first mealybug eggs and crawlers are seen in the field. Preventative measures are far more effective than curative control of mealybug.


Real PermiFIX is most effective at temperatures between 17-32°C.
