Photoperiod in relation to diapause in Lygus hesperus Knight

G. W. Beards and F. E. Strong

Hilgardia, 1966, vol. 37, issue 10

Abstract: Lygus besperus Knight, a common polyphagous insect pest of certain widely grown California crops, undergoes a seasonal facultative diapause. Experiments described here were conducted upon both field-collected and laboratory-raised L. besperus populations and have demonstrated the critical effects of photoperiod and temperature upon the inception, termination, nullification, and intensity of diapause in this species.
