A study of pupal-adult intermediates produced with juvenoid treatment ofSpodoptera litura Fabr. pupae

  • Published:
Proceedings: Animal Sciences

Abstract

Pupae ofSpodoptera litura were treated topically with a juvenoid, 6, 7-epoxy-3-ethyl-1 (p-ethyl phenoxy)-7 methylnonane. The effects comprised death, production of pupal-adult intermediates of varying grades and adultoids. The production of pupal-adult intermediates was studied in relation to age of the pupa at the time of treatment and the dose of the compound administered. It was found that up to the age of 20 hr the degree of morphogenetic response was directly correlated with the dose of the compound administered and inversely with age, but after this age, an increase in the quantity of the hormone, beyond the effective dose did not further augment the effect.
