| Popis: | Low levels of prostaglandin (PG)-like compounds were detected by radioimmunoassay in reproductive tissues of Trichoplusia ni adults. A 3-fold increase in PGE 2 -equivalents was found in mated female reproductive tissues. A PGF 2 x -like compound was found in reproductive tissue of mated females with a 2-fold increase over that in virgin females. Injected PGE 1 , PGE 2 and PGF 2 x had no effect on levels of Z -7 dodecenyl acetate ( Z -7-12: Ac) in pheromone-producing glands or oviposition of virgin female T. ni . No significant in calling behaviour were observed in virgin females injected with prostaglandin when compared with control virgin females. N -acetyl- p -aminophenol (NAPAP), a prostaglandin-synthetase inhibitor, in the diet of adult females did not alter calling behaviour of virgin or mated females. NAPAP in the larval diet lengthened larval stadia and slightly increased calling by mated females, but did not reduce oviposition after mating. Levels of Z -7-12:Ac in pheromone-producing glands of virgin and mated females were not affected by NAPAP in diets of larvae or adults. |
