“…Carpenter and Heitz (63) showed that when larval mosquitoes were exposed to rose bengal and visible light, significant acute mortality was observed. Further, if the treated mosquitoes were illuminated with visible light and then put into darkness, a latent mortality was observed.…”

Although light has been known to enhance certain toxic reactions since 1888, the principle was not exploited until after 1970 to any great extent. The greatest concentration of effort has been in the study of photodynamically active dyes, primarily the halogenated fluorescein series, as prospective insecticides. More recently, compounds of plant origin have been isolated, identified, and studied as phototoxins against a wide range of pests, including insects, fungi, and weeds. The main classes studied to this time are the furanocoumarins, thiophenes, acetylenes, extended quinones, and the chlorophyll a intermediates popularized as "laser herbicides." It is apparent that this area of research will expand in the coming years rather than retrench.The expenditure of energy frequently helps to enhance the probability of successfully reaching one's goals in this universe. For as long as chemistry has existed as a science, we have input energy, most frequently heat energy, into chemical reactions to make the molecules or to produce the effects which we wanted. The use of light energy has remained quantitatively a minor component as a means of energy input. This has also been the case with the development of the pesticide industry. Light energy has not been used to drive toxicological reactions or to provide specificity for those reactions to any great extent until the decade of the 70's. Several review chapters have been written covering individual aspects of photodynamically active pesticides (1-8). The purpose of this chapter is to provide a chronological treatment of the development of light as an integral part of the toxicological action of several classes of pesticides; and also, to show the development of the various classes of light activated pesticides relative to each other.

“…It was observed when using very low concentrations of rose bengal or erythrosine (Carpenter andHeitz 1980,1981 b), and several days elapsed before the pre-illuminated insects finally died in the dark; dye-treated controls, maintained entirely in the dark, were not affected. There appear to be species differences in the response to interrupted illumination in that Broome et at.…”

“…Studies on the toxicity of rose bengal to mosquito larvae have docu mented acute effects (Pimprikar et al, 1979) as well as latent effects (Carpenter and Heitz, 1980). The use of photodynamic action is currently being studied for possible control of the larvae of several other economically important insects: Lavialle and Dumortier (1978) reported on the cabbage butterfly Pieris brassicae; Creighton et al (1980) used rose bengal-impregnated artificial diets to kill the pickleworm Diaphania nitidalis, the cabbage looper Trichoplusia ni, and the corn earworm Heliothis zea\ and Clement et al (1980) used rose bengal, phloxin B, and erythrosin B against Agrotis ipsilon.…”
