Experimental designs for field and semi-field studies with solitary wild bees
Abstract
The newly proposed EFSA risk assessment of plant protection products for pollinators includes for the first time not only honey bees but also non-Apis pollinators (OEPP/EPPO 2010, EFSA 2013). No official guidelines for standardized tests exist so far. We performed field and semi-field studies to evaluate suitable test designs and handling procedures for the test organisms. The objective of these studies was the development of a test system for trials under field- and semi-field conditions with the red mason bee Osmia bicornis L. (Hymenoptera: Megachilidae).The trials were conducted in two different crops, winter oilseed rape (Brassica napus) and Phacelia (Phacelia tanacetifolia), with different nesting materials, test designs and release techniques.
