Vegetable Insects -- Film Description:
"The saboteurs of the vegetable garden, revealed in their fantastic forms and colors, preying on our crops, and sometimes on one another. Entomologists use their knowledge of the life cycles and feeding habits of these biting, boring, sucking and rasping food raiders to reinforce natural controls and safeguard the farmer's crops. Among the garden pests shown in close-up are potato beetles, caterpillars, aphids, cutworms, squash bugs, corn ear worms and root maggots."
