Abstract
Eggs of Conoderus vespertinus (F.) hatched equally well at constant temperatures of 75, 85, and 95[degree]F, and there was no hatch at 65 or 105[degree]F. Significantly more 6-day-old eggs survived short exposures to extreme temperatures than 1-day-old eggs. A high percentage of eggs hatched when held continuously in distilled water and at relative humidities (RH) of 95 and 100%. No eggs survived at 76% RH or below. Following 1- and 2-day exposures to lower humidities, hatch decreased with decreasing RH and increasing temperature.
