Jumbo Comics #63

Sheena and Bob get captured , tied up and almost fed to a mound of man-eating (and,persumably, woman-eating) jungle ants....
It's interesting that the bad guys here are identified only as "Facists", rather than specificaly German or Japanese..even though the book appeared in 1943..that and the art style makes me think it was drawn/written before America's entry into WWII..
