Abstract
The mussel scale Lepidosaphes ulmi (L.) is locally an important pest in apple and pear orchards.
Even light infestations can cause severe economic loss due to a zero tolerance on fruits for export.
The optimal moment for chemical control is when all crawlers have emerged from under the scales.
A temperature sum model was developed to indicate the best moment for observation and subsequent control.
