SUMMARY OF THE PRESENTATIONS ON INSECT PROBLEMS

Eleven oral presentations dealt with insect problems in pome fruits.
Three of them were devoted to problems caused by Heteroptera Miridae in different countries.
The main species were Lygocoris pabulinus and Campylomma verbasci, a species known as pest in North America, but not mentioned as pest in Europe in apples until now.
Some discussion about Miridae was carried out, as some of them can behave as phytophagous and as predators.
Modeling and forecasting of population dynamics of Cydia pomonella and Cacopsylla pyricola were treated in two oral presetations and in one poster, and two models from United Kindgom and Germany were proposed.
Some presentations dealt with faunistic studies under different pest control strategies.
The difficulties in defining what “conventional pest control” means were stressed.

Among the poster presentations, six dealt with Lepidoptera and three with Homoptera.
The use of pheromone traps for monitoring and for the disemination of virus and juvenoid insecticides through the males were discussed in three posters.
Other topics treated were the biological control of San Jose scale and aphids and the importance of secondary pests such as Grapholita prunivora and Stephanitis pyri.
