Abstract:

When maximum fat and minimum moisture content were used as criteria, adult Anthonomus grandis Boheman fed 11- to 15-day-old bolls and held at 26.7 attained firm diapause in I week; when the temperature was 21.1 during a 10-hr light peliod and l0 auring a 14-hr dark period, the weevils took 3-4 weeks to attain maximum fat and minimum moisture. Thus, time required for these adult weevils 1:0 attain firm diapause was inversely related to temperature. However, the weevils held at 26.7 and fed 11- to 15-day-old bolls attained firm diapause more rapidly than those fed 1 to 10-day-old bolls or squares, and the diet did not influence the time to firm diapause when the weevils were held at the lower temperatures.
