Pheromone trap Reagron Crabgrass (Rhagoletis cerasi,R.cingulata) 2 swarms
(Rhagoletis cerasi, Rhagoletis cingulata)
Package includes: 1 roof, 2 adhesive bottoms with bait material!
The species is the main pest of cherries and sour cherries
Larvae hatch in the fruit and pulp and contaminate the fruit by chewing and defecating. The adult larvae leave the fruit leaving a characteristic hole
The cherry fruit fly is widespread throughout Europe and is a persistent and persistent pest of cherries and sour cherries. It has one generation per year, with most intensive breeding in May and may last until early July. The eastern cherry borer is native to the USA and has been spreading in our country since 2006. It also has one generation per year, but its emergence is prolonged and can last until August. The pupae overwinter in the soil around the trees. The adult fruit flies are black in colour, only the tip of the throat may be yellowish. Their wing pattern is different and the two species can be distinguished by this pattern. The flies lay their eggs in the flesh within 5-10 days of hatching. The hatched larvae chew the inside of the fruit for 10-15 days during their development. The adult larvae dislodge themselves from the fruit and drop to the ground to pupate for overwintering.
Advice for control:
The first larvae usually hatch within 1-2 weeks after the start of swarming, with mass emergence occurring 5-10 days after the peak of swarming. Knowledge of the swarming period is very important as any chemical control is most effective during the peak swarming period. Disinfection by digging up the area under fruit trees will help control. Since cherry fruit flies generally fly over short distances, regular REAGRON trapping in a small garden will significantly reduce the population and thus the damage.
Placement of traps in late April is advisable. Replace the yellow sheets containing the bait in the glue every 8 weeks or so.
Check the traps twice a week. Count and record the number of flies caught during the period. From the data, the drawing dynamics can be seen and the time of intervention can be determined. If the trap captures few tansy flies even during the empirical swarming peaks, this indicates a low infestation. In small gardens, a few additional traps can capture the tussock borers and reduce the infestation. This will protect our health and our environment.
