BioAphytis is a small light-yellow parasitic wasp of about 1mm in size, the female wasps lay eggs under the waxy scale covering the nymph. A larva hatches and starts feeding on the scale as an ectoparasitoid, ultimately killing the scale insect and pupate. Adult female wasps actively search for suitable hosts; they prefer to parasitize 2nd and 3rd instar nymphs as well as unmated mature scale females. On average one female wasp can lay up to 100 eggs and can feed regularly on scale insects (host feeding) to obtain protein for egg development. Total development of BioAphytis from egg to adult is between 13 to 18 days depending on temperature. BioAphytis is well adapted to high ambient temperature of between 25°C to 35°C and low humidity. Aphytis pass through approximately three generations for every generation of red scale.

BioTrichogramma- The Product

  • BioAphytis is packed in disposable cardboard cups containing 10,000 adult parasitic wasps.
  • Each container consists of 8 corrugated cardboards.
  • It is shipped in insulated and chilled Styrofoam boxes, packaging must be kept intact until it reaches the end-user.
  • Keep in a cool location until release.
  • BioAphytis viability decreases rapidly with prolonged storage
  • About 2 to 3 weeks after release, parasitized scale insects should be clearly observed.
  • BioAphytis is very sensitive to different pesticides, for instance, insecticidal soaps are harmful to all stages of BioAphytis, but have no residual effect.
  • Oil sprays and Bacillus thuringiensis are compatible.
  • If harsh toxic pesticides must be used, BioAphytis should be re-introduced in 4 weeks after application.


  • During hot days, releases should be done during early morning or late afternoons.
  • 15 Release points per hectare, this can be achieved by traveling every third row and releasing some wasp every 25 meters.
  • To apply, open the lid of the container and allow some wasp to fly out onto the foliage.
  • Gently tap the lid to dislodge wasps from the lid/ rim of the container onto the foliage.
  • Place one corrugated cardboard into the tree canopy for each release point. After all the corrugated cardboard has been removed, place the container into the tree for the final release point.
  • General introduction rate: First application is a minimum of 25,000 wasps per ha (2.5 container per Ha) for 4 releases, 4 weeks apart.
  • Timing of application: as early as possible in the season, however generally releases starts in January to April.
