Abstract:
The juvenile hormone analogue, methoprene was found to interfere with normal development of Ephestia in a manner dependent on age. Young embryos, prior to the stage of blastokinesis, and animals, shortly before and after pupation, were found to be the most sensitive to the compound. The JHA inhibited metamorphosis and produced giant larvae when it was given to immature larvae, however, when it was given to larvae 2-3 days prior to pupation or to young pupae it did not affect metamorphosis but prevented adult emergence. Comparison of the ecdysteroid titre determined in control and treated animals in the various developmental stages showed that JHA depressed the ecdysteroid titre totally only when it was given to young larvae and partially when it was applied shortly before pupation. It seems that the action of methoprene on ecdysone regulated systems and/or ecdysone producing systems in Ephestia appears to be mainly during the larval stage prior to the appearance of the small ecdysteroid peak and the formation of HnRNA in the transition period from larvae to pupae. © 1986.
