Table 4. Mortality of AMF after exposure to PTS. All evaluated PTS were retrieved 

 from commercial orchards at the end of the season: for wooden PTS, 12 weeks of 

 field exposure after deployment in early July accompanied by replacement of 

 sugar/wax discs in mid-August; for sugar/flour PTS, 6 weeks of field exposure after 

 deployment in mid-August. AMF were exposed individually to each PTS and allowed 

 to forage freely on it for up to 10 minutes. 



* Each value is based on sphere exposure to 120 AMF (10 AMF per sphere x 2 



spheres per orchard x 6 orchards). 

 ** 20% sugar solution applied to sphere surface prior to fly exposure.
