AB  - Thrips-infesting soybeans were considered of minor economic importance, but 
      recent evidence of their ability to transmit a newly identified soybean virus, 
      Soybean vein necrosis virus (SVNV), has raised their profile as pests. 
      Season-long surveys were conducted using suction traps to determine the effects 
      of temperature and precipitation on the spatiotemporal patterns of three vector 
      species of SVNV, Neohydatothrips variabilis (Beach) (Thysanoptera: Thripidae) 
      (soybean thrips), Frankliniella tritici (Fitch) (Thysanoptera: Thripidae) 
      (eastern flower thrips), and Frankliniella fusca (Hinds) (Thysanoptera: 
      Thripidae) (tobacco thrips) in soybean fields in Indiana in 2013 and 2014. In 
      addition, soybean fields were surveyed for presence of SVNV in both years. We 
      found that the magnitude and timing of thrips activity varied greatly for the 
      three species. N. variabilis activity peaked in mid-August each year. The peak 
      activity for F. tritici occurred between late-June, and a second peak in activity 
      was observed in early-August, while F. fusca activity remained more or less the 
      same with no peak. There was no gradient in thrips populations from southern to 
      northern locations. This suggests that these insects are not migratory and may 
      overwinter in soil or perennial noncrop host plants and other weed hosts in 
      Indiana. The capture rates of N. variabilis and F. tritici were only related to 
      temperature, and capture rates of F. fusca were not related to either variable. 
      SVNV was first detected in mid-late August, which coincided with the peak of the 
      primary vector, N. variabilis. The virus was not detected earlier in the season 
      despite peaks in F. tritici activity. Our results may be used in weather-based 
      models to predict both thrips dynamics as well as SVNV outbreaks.
