Survival and attraction of virgin and mated male and female almond moths, Cadra cautella (Walker), to wheat grain in traps was tested during their life span in the laboratory at 25 plus minus 1 degree C, 65 plus minus 5% R. H. The life span of virgin females was longer than of mated females with 50% survival of 15 vs. 8.5 days respectively. Similarly, virgin males also lived longer than mated males with 50% survival of 9.5 vs. 6.5 days, respectively. Catch of mated females in traps baited with wheat was low on the first and second day of life and even less so in virgin females; thereafter daily catches increased and ranged around 45% in both mated and virgin females until the time of 50% survival. After that age, catches decreased in both cases. Attraction of either mated or unmated males to wheat grain was negligible. Two-choice tests were conducted using wheat paired with one of eight different foods: almond, peanut, walnut, corn, soybean, date, fig and raisin. Except for fig and raisin which were less attractive than wheat, all other foods tested were equally attractive. The behavioral results obtained in this study are of importance in planning control and monitoring systems for this moth
