Suppl. Fig. S1. Pollen beetle mortality rates at various lambda-cyhalothrin dosages depending upon 
the year, both in fields containing spring oilseed rape (SOSR) and winter oilseed rape (WOSR). The 
shapes denote observed mortality in different fields, with bigger crossed shapes joined by lines 
marking out the marginal means which have been estimated using a logistics model, taking into 
consideration the effects of dosage, year, and host crop, and all two-way and three-way interactions.

 

Suppl. Fig. S2. Pollen beetle mortality rates at different thiacloprid dosages depending upon the 
year, both in fields containing spring oilseed rape (SOSR) and winter oilseed rape (WOSR). The 
shapes denote observed mortality in different fields, with the bigger crossed shapes joined by lines 
marking out the marginal means which have been estimated using a logistics model, taking into 
consideration the effects of dosage, year, and host crop, and all two-way and three-way interactions.
