May 23, 2025 Update
General Situation: Daily high temperatures will be sitting between the high 80s and 105F over the next 10 days. These are good conditions for thrips development, but sustained heat at or above 100F might slow population growth down a little.
Thrips development: Generation 3 adults will reach their peak numbers around May 29th. Generation 4 will be developing on plants during the first 3 weeks of June, reaching peak adults around June 20th. For most crops these two generations will present the highest risk of TSWV spreading and causing yield loss. Focusing thrips treatments into the next 4-6 week window will help keep TSWV damage to a minimum.
