General Situation: Daily high temperatures will be swinging between the low 70s and high 80s F over the next 10 days.  These are ideal conditions for thrips development. 

Thrips development: Generation 2 adults will reach their peak numbers around May 14th.  Generation 3 will be developing on plants this month and early June, reaching peak adult numbers around June 12th.  Generation 4 will be developing on plants during June, reaching peak adults around July 6th.  For most crops these two generations will present the highest risk of TSWV spreading and causing yield loss.  Focusing thrips treatments into the next 8-9 week window will help keep TSWV damage to a minimum.
