Montyline biological control agent contains the predatory mite, Amblyseius montdorensis. It is a predatory mite that feeds on many types of small arthropod prey and pollen. It is ideal for preventive control of whitefly and thrips in greenhouses. Montyline is active at a broader range of temperatures than other predatory mites, making it perfect for controlling pests in challenging environmental conditions.

Please note: Not all products/species will be available in all countries. Licence restrictions may apply to the use of some products. For more information contact your distributor or Bioline AgroSciences.

Key Features

  • Excellent control of both Whitefly and Thrips
  • Superior Thrips control because it is able to predate upon both first and second instar larvae
  • Activity at a lower range of temperatures gives better establishment in cooler crops (12-18oC)
  • Explosive population growth gives better recovery after cold environmental periods
  • Strong secondary suppression of Spider mites and Eripohyid mites

Main uses

  • Whitefly
  • Thrips
  • Eriophyids & Tarsonemid mites

How It Works

  • Ideal for use on peppers, cucumbers, aubergines, strawberries and cut flowers. It can be used on non-protected crops, provided temperatures do not remain below 10-12°C for extended periods.
  • Establishment will be fastest on crops with ample pollen, such as pepper crops, as the pollen provides an alternative, high quality food source for the mites.
  • Crops without pollen will have slower establishment, but using sachets that continually release mites over several weeks will improve results.
  • Best used early in crop/pest cycle to prevent whitefly and thrips buildup

Available delivery systems


Sachets release a breeding colony of mites onto the plant, even before the target pest is present. The breeding colony is contained within a small paper sachet, which is carefully designed to maintain the colony in good condition. Mites continue to emerge from sachets over several weeks and in much higher numbers than with a single broadcast release.
Mini sachets
Mini sachets are best used where the leaves of plants are not expected to touch or grow together. Mini sachets provide a high number or release points to ensure good spread and establishment of mites.
  • Sachets represent an improved breeding system that provides continuous and consistent release of beneficial insects over several weeks.
  • For advice on recommended release rates, consult The Bioline App.

Gemini sachets

Gemini sachets are best used with crops that are watered via overhead irrigation or where a horizontal wire or string exists. Gemini sachets are water-resistant and the release holes are inside the folded sachets so the contents are protected from the water.  Gemini sachets offer the following benefits:
  • Unique, patented, water-resistant twin sachet design with two predator-breeding compartments.
  • Water runs off outer surface and keeps inner surface and emergence holes dry, so sachet contents are protected. There is no hook to get wet, so sachets remain in plants.
  • Water-resistant design allows for maximum emergence of predatory mites.
  • For advice on recommended release rates, consult The Bioline App.


Bugline 6x100m strips of sachets. The Bugline delivery system is a unique, patented delivery system for controlled release of particular species of Bioline biological control agents. It was developed by Bioline to help growers reduce the manual labor associated with using sachets or applying loose material.
  • Bugline is especially useful in a cut flower operation, such as cut chrysanthemums, where Bugline can be placed on top of the crop support mesh wiring.
  • Can be mechanically layered onto crop saving up to eight labor hours per acre compared to using single sachets.
  • Unique design of Bugline ensures maximum emergence of BCAs even under stressful conditions.
  • Works well in crops watered by overhead irrigation because water runs off outer surface while the emergence hole stays dry on lower surface.
  • Provides preventive control of damaging pests with continuous emergence 24/7 for 4-6 weeks.
  • For advice on recommended release rates, consult The Bioline App.

Bulk Bags & Tubes

  • Available as loose material in 5L bulk bags containing 125,000 or 250,000 mites, or 1L cardboard tubes containing 25,000 mites.
  • For advice on recommended release rates, consult The Bioline App.

Handling & Storage

Instructions for Gemini or Mini Sachet Use

  • Do not hang adjacent to heating pipes.
  • Do not hang sachets where they will be directly exposed to intense sunlight.
  • Open the shipping box of sachets in the crop.
  • Separate sachets by tearing along perforations.
  • For advice on recommended release rates, consult The Bioline App.

Instructions for Bugline

  • Distribution of the strips can be done by attaching to the irrigation boom and pulling strips from the box down the greenhouse bay or manually by pulling it into the crop.
  • Make sure the crop and floor are dry when applied. If crop and/or floor are wet, water can enter Bugline through the holes, and could result in some predatory mites within the cells being lost.
  • Do not use adjacent to heating pipes.
  • For advice on recommended release rates, consult The Bioline App.

Instructions for Bulk Bags & Tubes

  • Keep containers horizontal and cool until use.
  • Do not expose to direct sunlight at any time.
  • Immediately before opening, gently rotate the container to distribute mites evenly throughout the carrier material.
  • Open each container in the crop when ready to use.
  • Shake small quantities of Montyline onto crop near flowers.

Storage and transport

  • Keep out of direct intense sunlight.
  • Transport and store at 50-59°F/10-15°C and >65% humidity.
  • Use within 18 hours of receipt.
  • Do not refrigerate.
