Abstract
The average winter survival of the bollworm, Heliothis zea, in cages at Waco, Tex., from 1940 to 1948 was 12.2% in Houston clay soil and 24.6% in mixed soil. It varied from year to year, being very low in 2, high in 4, and moderate in 3 years. Survival, similar in the 2 soils in 4 years but greater in mixed soil in all other years except one, appeared to be influenced by winter and spring rainfall. Earliest emergence occurred on April 9 and latest on June 30. In several years bollworm eggs and larvae were found on hosts in the field before moths emerged in cages.This publication has 1 reference indexed in Scilit:
