Whitefly

Trialeurodes vaporariorum · Bemisia tabaci

Small white flying insects clustering on leaf undersides. Croptimus counts populations per leaf for IPM threshold decisions.

  • Hemipteran
  • Sap-sucker
  • Virus vector
  • Greenhouse-endemic

Signs Croptimus looks for

  • White flying adults rising from canopy when disturbed
  • Cluster of adults and nymphs on leaf undersides
  • Honeydew sticky residue on leaves
  • Sooty mould growing on honeydew
  • Chlorotic stippling on upper leaf surface from nymph feeding

Recommended action

Release Encarsia formosa or Eretmocerus at first detection above threshold. Croptimus's leaf-level counts let you target releases to specific zones rather than blanket distribution.

Whitefly is one of the most economically damaging greenhouse pests – both directly through sap-feeding and indirectly as a vector for tomato yellow leaf curl virus and other geminiviruses.

Croptimus’s continuous leaf-level monitoring gives IPM teams the “when” of beneficial releases, not just the “whether”. That timing precision is where biological control beats reactive chemistry.

Frequently asked

  • Does Croptimus distinguish T. vaporariorum from Bemisia?

    Differentiation by visual cue alone is challenging even for trained scouts. The model identifies the "whitefly" class reliably; species-level disambiguation in a separate validation phase typically uses sticky-trap PCR.

  • How does the model count flying adults?

    Frame-to-frame motion detection plus shape matching. The model excludes other small insects (sciara flies, scatella) using both visual and behavioural cues.
