6 ADULT TRAPPING Use recommended trp (Drosotrp) nd bit (Dros Attrct) Continue to monitor until November or when utumn fruiting crops finish picking Identify hot-spots ble to trget controls 6

7 ADULT TRAPPING Trps re useful inside the crop to ssess the efficcy of control tretments Are your tretments reducing dult popultions? 7

8 % of detection by dissection LARVAL MONITORING more effort Monitor ripest fruits, low down ner edges of crop - with every pick Do not pick fruit from the floor Sugr flot test quick, esy, low cost Emergence testing: ccurte picture over time cn pick up erly egg lying b b c Sugr Slt b b b Blueberry Cherry Rspberry Strwberry b b 8

12 PRECISION MONITORING PERIMETER TRAPPING Perimeter trpping: erly to intercept SWD leving wild hbitts In plce when detected in spring in hedgerow before crop fruiting Every 2 m every 4 weeks When replcing hng in-between old devices See Agrln for cheper hngers 12

13 CHEMICAL CONTROL - CHERRY Old fruit on tree Protect ripening cherry fruits from white stge until hrvest Weekly sprys (spinosd - covered) (spinosd/hllmrk unprotected) Not ll vrieties t sme time Remove bird nets sp fter hrvest birds nd mmmls Ground fun feeding on flesh of dropped fruits 13

14 CHEMICAL CONTROL - GENERAL Long protection Some protection Medium term Short protection Soft fruits tight picking trp ctches & lrvl counts predict spry times Not so effective Chlorpyrifos Thicloprid Pyrethrin Lmbd cyhlothrin Spinosd Acetmiprid Lmbd cyhlothrin Chlorntrniliprole Deltmethrin Pyrethrin 14

15 Consider Competition on ground with other Drosophil Netting blueberry 0.98 mm Brmble neighbouring hbitt wild berries nd overwintering sites 15

16 Consider Remove netting from cherry ASAP fter hrvest to llow birds nd mmmls to clen up fruit on the trees nd ground Consider pesticide effects: biocontrols, ntive predtors nd detritivore rthropods, resistnce Biologicl control of other pests sensitivity to pesticides Predtory mites in rspberry, strwberry, cherry chlorpyrifos spinosd lmbdcyhlothrin cetmiprid thicloprid toxicity >75% >75% >75% 25-50%, 50-75% persistence 6-8w 2w 8-12w 5d 0 (no dt) 16
