Orchard 



Figure 5. A) Proportions of piiytoseiid mites identified as either T. pyri or A. fallacis in each of 12 orchard blocks 

 over three years. Within a year there are 12 sets of circles denoting the T. pyn proportions and 12 + symbols 

 denoting the A. fallacis proportions. At some sites, no phytoseiids were collected and these are denoted by a circle 

 enclosing a + symbol. B) Maximum densities of European red mites in relation to the average density of T. pyri. 

 Each circle represents data collected from a block in one of the years 2001, 2002 or 2003. The dashed line was 

 fit by eye. C) Average densities of T. pyri in orchards over the years 2001, 2002 and 2003. Each set of three 

 connected circles represents three years of data from an orchard block, arranged in sequence (left to right) for 

 2001, 2002 and 2003. Circles with a + symbol indicate no T. pyri were collected in the samples.
