Abstract
The life history of Lygus hesperus Knight was investigated in a laboratory maintained at 80° ± 2° F., with a 15-hour light day. Bean pods served as food and oviposition hosts. Shell vials were used as rearing cages in which bugs were confined individually. Average durations of the life stages were: egg, 7.1 clays for both sexes; total nymphal, males 13.2 days, females 13.8 days; adult, males 35.2 days, females 43.4 clays. The sex ratio was 113 males to 100 females. Females averaged 9.6 pre-oviposition and 32.2 egg-laying days, and deposited an average of 202.4 eggs per female (maximum, 448 eggs). Under the experimetal conditions oviposition and eclosion occurred throughout the 24-hour day.
