Technical Abstract: We have simulated hourly temperatures to examine Lygus response to hot summers in the San Joaquin Valley. Constant temperature of 33C quickly killed Lygus and SJV temperatures routinely surpass this level. Average hourly temperatures were tested for the months May, July, and September. Age specific fecundity was measured in our standard bean/sunflower seed diet. The results show heat stress in late summer has an adverse affect on Lygus populations, which corroborates observed seasonal population dynamics
