Fang N., Teal P. E. A., Doolittle R. E. and Tumlinson J. H. (1995a) Biosynthesis of conjugated olefinic systems in the sex pheromone gland of female tobacco homworm moths, Manduca sexta (L.). Insect Biochem. Mol. Biol. 25, 39 18. 

Ouye and Butt 32) have recently shown that a stable sex attractant for males can be extracted from copulating pairs of pink boUworm moths [Pectinophora gossypiella (Saunders)], with ether or methylene chloride, and Allen and coworkers ) have reported the extraction of a potent sex attractant from the abdomens of female tobacco homworm moths [Protoparce sexta (Johannson) ] with these same solvents. The chemical nature of these attractants as well as that of the southern armyworm moth [Prodenta eridania (Cramer) ] is at present under investigation in U. S. Department of Agriculture laboratories. 

Other food lures which have had practical use ia trapping insect pests include isoamyl saUcylate [87-20-7] for moths of the tomato and tobacco homworms, Manduca spp. heptyl butyrate [5870-93-0] for stinging yeUowjackets, Vespula spp. and l-octene-3-ol [3391-86-4] for the bloodsucking tsetse dies, Glossina spp. 

Cecropins. Cecropins (169) were isolated from the larval hemolymph of the giant silkworm moth, Hyalophora cecropia, on the basis of their antibacterial activity subsequent to bacterial injection. Cecropins are also produced by Drosophila (170) and the larva of the tobacco homworm, Manduca sexta (110). Similar compounds called sarcotoxins (171) are produced by the flesh fly, Sarcophaga. Cecropins (169) are specific for prokaryotic cell lysis in contrast to melittin, which lyses eukaryotic cell membranes as well. Cecropins are characterized structurally by a concentration of basic... 

In this report, we will discuss investigations of the cuticular components from Nicotiana species and their effects on tobacco homworm and tobacco budworm moth oviposition. The response of tobacco budworm moths to specific cuticular isolates from a Nicotiana species also will be discussed.
