Using Semifield Studies to Examine the Effects of Pesticides on Mobile Terrestrial Invertebrates

• Description of Supplemental Table 1:

  We conducted a quantitative analysis of recently published field-plot trials in broad-acre crops that examined pesticide effects on pest and natural enemy species. We searched Arthropod Management Tests publications for the years 2005 and 2010, focusing just on the 'field crops and cereals' section (F) (www.entsoc.org/Pubs/Periodicals/AMT). In addition, we manually downloaded and searched the open-access IOBC Working group 'Pesticides and Beneficial Organisms' bulletins for the years 2000-2004 (www.iobc-wprs.org/pub/bulletins/index.html). We have summarized a range of characteristics in 156 trials (see Supplemental Table 1 Supporting Information). These trials were mostly pesticide comparisons that used a field-plot design. We categorized the pest or natural enemy species assessed into three mobility classes: low mobility (e.g., Lepidoptera larvae, Acari, Diptera larvae), medium mobility (e.g., Hemiptera, Thysanoptera), and high mobility (e.g., Aphididae, Lepidoptera adults, Coleoptera). We then examined the relationship between mean plot size and mobility score and found that trials focused on species with lower mobility used smaller plot sizes than those that focused on species with higher mobility (see Figure 2 in the text).
