Abstract:Methods of artificially infesting corn with eggs of Heliothis zea (Boddie) were evaluated by using 4 applicators, various rates of eggs per silk, 2 infestation dates (100% silk and 7 days later), and 2 times (AM or PM) on 4 different sweet-corn hybrids. Infestation with 30 eggs/silk yielded larvae adequate to obtain damage equal to 3 larvae/silk. A pressure applicator (handlotion dispenser) was judged superior to other applicators (chromatographic sprayer, hypodermic syringe, and squeeze bottle) because of its overall performance with respect to accuracy, ease in handling, and capacity to transfer the eggs suspended in agar with minimum egg damage.
