Abstract

The grass webworm, Herpetogramma (Pachyzancla) licarsisalis (Walker) (Lepidoptera: Crambidae) severely infest turf and lawn grasses (green spaces) in Egypt. It easily domesticated in the laboratory, especially in an externally supported breeding cage and the protected outdoor cage. Adults require a sugar solution or floral nectar to achieve maximum longevity and increase the production of fertilized eggs, which female moths lay on the upper surfaces of the host turf grass. The present study aimed to rear larvae on Paspalum vagenatum and Cynodon dactylon in plastic trays. Pupae were maintained in cubic screens and transparent boxes to emergence. The generation period lasted at least 28 days at a temperature of about 25 °C. By observation and experimentation, it is recommended not to plant flowering plants such as Lantana camara near the Lawns (Turf grass), because its flowers attract adult moths and provide them with food. Feeding on the nectar of its flowers affects the density and number of eggs from other insect hosts and a distinctive place to hide.
