Pilot Program — Spring 2026

Aphid Resistance Testing

Know where your population stands. DNA-based resistance testing for commercial greenhouse operations — a profile specific to your crop, not a generic report.

Why It Matters

Resistance builds before
spray failure is obvious

Aphid populations in enclosed greenhouse environments develop pesticide resistance quickly — especially under repeated chemistry. A population can be 80% resistant before spray failure becomes apparent. By then, the season is already compromised. DNA-based testing gives you a picture of your population before the decision moment, not after.

80+
offspring per aphid, per week
No mating required. A small infestation can become a serious problem before it's visually obvious.
15
generations for resistance to establish
Aphids cycle 15–20 generations per year in enclosed environments. A 1% resistance mutation can dominate within a single season.
100+
plant viruses transmitted by green peach aphid
More than any other insect on earth. In many cases the economic damage isn't from feeding — it's from what gets left behind.
Population resistance progression
Susceptible aphid population — mostly green, few resistant individuals
Susceptible populationLow resistance frequency. Most individuals respond to treatment.
Mixed aphid population — roughly equal susceptible and resistant individuals
Emerging resistanceMixed population. Spray efficacy declining — visible failure is close.
Resistant aphid population — mostly orange-red, few susceptible individuals remaining
Resistant populationResistance dominant. Current chemistry no longer effective.

What We Test For

A resistance profile for your
specific population

This test screens for resistance mutations using DNA-based methods — detecting which genetic markers are present in your aphid population, across the insecticide classes used in greenhouse programs.

The resistance profile in your operation depends on your specific spray history. Without testing, it's difficult to know where you actually stand. The result tells you which modes of action still have efficacy in your population — so the next chemistry decision has something to stand on.

Species screened: Green peach aphid (Myzus persicae) and cotton/melon aphid (Aphis gossypii) — the two most economically significant aphid species in Canadian greenhouse operations.
Neonicotinoids
Most common resistance class in enclosed greenhouse populations. Documented worldwide, including Canadian operations.
Carbamates (pirimicarb)
Resistance documented in some Ontario greenhouse populations.
Pyrethroids
Variable resistance. Used in some operations with label restrictions.
Organophosphates
Declining use in commercial greenhouse settings. Included to complete the resistance profile.

FAQ

Common questions

This test uses DNA-based methods to detect specific resistance-associated mutations in your aphid population. It does not measure mortality rates or spray trial outcomes — it tells you which genetic markers linked to resistance are present, and at what frequency, in your collected sample.
The test screens for resistance in green peach aphid (Myzus persicae) and cotton/melon aphid (Aphis gossypii). These are the two most economically significant aphid species in Canadian commercial greenhouse operations. If you're unsure which species you have, let us know when you submit — we can help you identify before you collect.
After you submit your request, we'll send you documented sampling and handling protocols specific to your collection context. Aphid samples have specific preservation requirements — we walk you through exactly what to do before you collect. Do not collect a sample before receiving these instructions, as improper preservation will affect result quality.
The specific collection requirements are confirmed when we send your sampling instructions. In general, a population-level resistance test requires a sufficient sample size to reflect the range of individuals in your greenhouse — we'll tell you the target number and how to collect across your zones.
The panel covers neonicotinoids, carbamates (pirimicarb), pyrethroids, and organophosphates — the four classes most commonly used in greenhouse aphid management programs. These represent the modes of action where DNA-based resistance markers have been validated for Myzus persicae and Aphis gossypii.
Results are delivered with a direct walkthrough — we go through what the resistance profile means for your specific operation, which chemistries still have efficacy, and what the findings suggest for your spray rotation decisions. The result is not a raw data dump. We connect it to actionable IPM context.
Yes. The pilot is open to commercial greenhouse operations across Canada. If you're outside Canada and interested, reach out — we'll confirm whether your submission context can be accommodated.
After the pilot period ends, standard pricing will apply. Pilot participants will be notified before any pricing change takes effect. We'll also share a summary of what the pilot data showed — anonymized and aggregated across operations — as part of the research value exchange for participation.
