Vliegenbestrijding in de biologische varkenshouderij: een enquête en evaluatie van een meetmethode = Fly control on organic pig farms: a survey and evaluation of a monitoring method
Organic farming is associated with biological solutions for pest control. Flies can be such a nuisance on organic pig farms that the farmers turn to chemical weapons for controlling the problem. This became apparent after an interview of 39 organic pig farmers. Half of the farmers used chemicals to control flies and only five mentioned the use of natural predators. Manure management on many farms was irregular and was not adequate for optimal fly control. Some farmers circulated the manure in an attempt to drown fly larvae and pupae. Monitoring methods to quantitate flies in the stables showed that the sticky traps was preferred over the spotcard method
