The complete ovipositional rhythms ofThyanta pallidovirens(Stal) fed peas, beans, or lentils and the diel ovipositional rhythms when fed beans were determined in the laboratory. The ovipositional response of these insects was significantly affected by the food provided;T. pallidovirensthat were provided peas produced significantly more eggs ($\bar x$= 295) than those provided beans ($\bar x$= 165) or lentils ($\bar x$= 122).T. pallidovirensfed peas had constant eggs per clutch (E/C) and number of days between clutches (DBC) over the ovipositional period; whereas those fed beans or lentils had significant negative slope when E/C or DBC were predicted by either days from first oviposition or number of clutches already laid.T. pallidovirensthat were fed beans had a consistent diel ovipositional cycle with 1500 and 1700 hours having significantly more oviposition than 400, 1600, 1800, and 1900 hours, which were significantly greater than 200, 2200, 2000, 1400, and 2100 hours, which were significantly greater than the remaining hours. There was also a consistent diel mating cycle for this insect, with 400, 500, 600, and 700 hours having significantly more mating than 800, 900, 2200, 2100, and HOO hours, which were significantly greater than the remaining hours.
