EFFECT OF KHELLIN AND 8-METHOXYPSORALEN ON THE DEVELOPMENT AND SURVIVAL OF AEDES ATROPALPUS

Abstract
Secondary metabolites from plants capable of photosensitizing insects include furanocoumarins, furanoquinone alkaloids, beta-carboline alkaloids, polyacetylenes and their thiophene derivatives, and extended quinones (Arnason et al. 1983; Towers 1984). These compounds may have direct lethal effects, retard larval development, or be ovicidal (Kagan and Chan 1983). A remarkable property of these secondary metabolites is their greatly enhanced activity in the presence of sunlight or artificial sources of radiation.
