BarkeLiv (Neoseiulus barkeri) is a predatory mite widely used for managing cyclamen mites and other small pest mites in greenhouse crops. It is highly adaptable and can survive on pollen when prey is scarce, ensuring consistent activity and population persistence even under fluctuating environmental conditions.
Feeding Habits
Both nymphs and adults of BarkeLiv (N. barkeri) feed on all four stages of cyclamen mites. By targeting all life stages, BarkeLiv (N. barkeri) prevents population buildup before serious plant damage occurs. Its generalist feeding behavior allows it to also consume spider mites, broad mites, and other soft-bodied pests. In the absence of prey, it survives on pollen, maintaining readiness for future infestations.
Lifecycle of Neoseiulus barkeri
Egg Stage: Eggs are laid on the underside of leaves or within young folded tissue where cyclamen mites tend to hide. They hatch within 1–2 days under favorable conditions.
Larval Stage: This is a non-feeding stage that lasts about 1 day.
Nymphal Stages (Proto- & Deutonymph): Feeding begins during these stages, each lasting 3–4 days. Both stages are active predators of cyclamen mite larvae and nymphs.
Adult Stage: Adult females begin laying eggs within 1 day of emergence. The complete lifecycle takes 7–10 days at optimal greenhouse temperatures (24–27°C). The typical sex ratio is 1 male to 2 females, supporting rapid population growth and continuous predation.

Benefit |
How It Helps Growers |
|
Direct suppression |
Nymphs and adults actively feed on cyclamen mite immatures, reducing pest pressure efficiently. |
|
Multi-pest protection |
Also preys on broad mites, spider mites, and other small arthropods. |
|
Persistence |
Can survive on pollen, sustaining populations even when pests are temporarily absent. |
|
Adaptability |
Performs well under a broad range of greenhouse temperatures and humidity levels. |
Storage Conditions
BarkeLiv (N. barkeri) should be released as soon as possible after arrival. If temporary storage is required, keep it at 10–15°C in a cool, dry place away from direct sunlight and strong airflow. Storage should not exceed 1 day to preserve predator quality and effectiveness.
Application Guidelines
Before release, gently roll the container to distribute mites evenly. Apply directly to the crop canopy, concentrating on young shoots, buds, and leaf folds, areas where cyclamen mites are most likely to occur. Release rates should be adjusted based on crop type, pest pressure, and environmental conditions. Consistent monitoring after application ensures proper establishment and sustained control.
Optimal results are achieved at 24–27°C with relative humidity above 60%. Preventative introductions help maintain stable predator populations before cyclamen mite outbreaks occur.
Recommended Release Rates

Strategy |
Release Rate |
Interval |
|
Preventative |
25–50 mites/m² |
Every 14–21 days |
|
Curative |
200–250 mites/m² |
Every 7 days |
Preventative releases are the most efficient and sustainable strategy. Early establishment of BarkeLiv (N. barkeri) ensures continuous suppression of cyclamen mites, reducing the need for reactive treatments and supporting long-term crop health.
