Effects of fenoxycarb on the secretory activity of the prothoracic glands (PGs) of the silkworm, Bombyx mori, were investigated. Fenoxycarb inhibited the secretory activity of PGs in vitro throughout the fifth instar. Incubation of PGs in the presence of 1 microgram of fenoxycarb resulted in a approximately 50% inhibition of their secretory activity. This inhibition of fenoxycarb was dose dependent. Stimulation of the PGs by recombinant prothoracicotropic hormone (rPTTH) reached a high activation ratio of 15.9. Simultaneous presence of fenoxycarb and 1 ng rPTTH significantly decreased the stimulatory effect of rPTTH on the PGs, and the activation ratio never exceeded 3.65. Early in the fifth instar, fenoxycarb strongly inhibited the secretory activity of the PGs and induced a developmental arrest as well. After the onset of pupal commitment, its action toward the PG secretory activity was inhibitory. However, fenoxycarb treatment was not able to induce a developmental arrest in intact animals after the pupal commitment although it could do so in head-ligated animals. On the contrary, application of fenoxycarb after the wandering behavior resulted in a significantly increased secretory activity by the PGs of both intact and head-ligated larvae.
