Abstract
A high-capacity assay designed to evaluate insect-induced foliage damage was developed based on the optical density of dimethyl sulfoxide extracts of leaf tissue. The assay reliably indexed foliage damage induced by both chewing insects, Spodoptera eridania (Cramer), and piercing-sucking insects, Empoasca abrupta DeLong. Results from this assay correlated well with simulated damage levels, insect infestation levels, leaf dry-weight measurements, and visual leaf damage estimates. Results from dose-response tests with malathion using larvae of S. eridania indicate that this assay is useful for evaluating chemicals for their ability to protect plants from insect damage. The assay could be adapted to evaluate other types of plant damage such as those induced by herbicides, air pollutants, or disease.
