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

Cranberry tipworm Dasineura oxyccocana
• 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
• 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)

Monitoring in blueberry of Florida
• Emergence trap developed for blueberry gall midge in blueberry rabbiteye (Roubos & Liburd 2010)

Emergence traps developed in Quebec
Petri dish trap (P1) Plate trap (P2)

Objectives and set up
1. Which trap perform better?2. Are adults populations
correlated with eggs or larvae populations?
3. Where to set up the trap?4. Is the scouting with a trap
more costly (labor)

In summer 2013
• Petri dish trap• 12 farms• 12 traps in each field• Early may to September• HOBO loggers

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.
