Sampling techniques for Liriomyza huidobrensis in potato fields
Studies have been carried out in Israel in order to define the optimum monitoring and sampling techniques of Liriomyza huidobrensis (EPPO A2 quarantine pest) in potato fields. It was found that yellow sticky traps placed at plant height caught significantly more adult flies. No difference were observed between traps placed horizontally and traps placed vertically. Activity of the pest during the day was also studied, and peak activity was observed in May and June just after sunrise and then decline. The authors concluded that this type of study provides useful information for pest management programmes, and could help for a better timing of chemical treatments.
