Emergence trap for monitoring the cranberry tipworm Dasineuraoxycoccanain Quebec

Cranberry tipworm Dasineuraoxyccocana
  • Diptera pest presents in North-America
  • Attacks shoots of cranberry and provokes gall
  • In blueberry: blueberry gall midge but reproductive isolation (Cook, 2011)

  • 25% of the field in Quebec with damage
  • In general upright damaged produces 50% less fruits (Le Duc 2010)
  • When infested by the 3rd generation: 33% of fruiting buds are recovered the next year (Le Duc 2010)

scouting
Scouting
  • Current scouting: 100 shoot observed under binocular = time consuming!
  • Need for adult scouting to better predict egg population, generation and spraying date
  • MOVENTO 240 SC registered, application after flowering at egg hatching
  • Different methods tested or under development for monitoring adults (Sarzinsky & Liburd, 2003, talk of S. Fitzpatrick)

objectives and set up
Objectives and set up
  • Which trap perform better?
  • Are adults populations correlated with eggs or larvae populations?
  • Where to set up the trap?
  • Is the scouting with a trap more costly (labor)

conclusion
Conclusion
  • Petri dish efficient to capture adults
  • Good correlation with eggs but better with larvae
  • Appears less costly in time of labor
  • Data integration in forecasting model predicting eggs and larvae generation.
