Comparative sterilizing and ovicidal activity of fenoxycarb and hydroprene in adults and oothecae of the German cockroach (Dictyoptera: Blattellidae).
Adults and oothecae of the German cockroach, Blattella germanica (L.), were treated topically with the juvenoids fenoxycarb and hydroprene. Fenoxycarb suppressed reproduction when applied at 10 micrograms/microliters to virgin and fertilized females. Production of offspring also was reduced when males treated with 10 micrograms/microliters of fenoxycarb were mated with untreated females. Fenoxycarb (10 micrograms/microliters) also exhibited ovicidal activity, particularly when applied to 4-d-old oothecae. Ovicidal activity by fenoxycarb diminished when applied to oothecae older than 8 d. No reproductive or ovicidal effects were caused by 1 or 10 micrograms/microliters of hydroprene.
