Abstract:Ovicidal activity of the benzoylphenylurea noviflumuron was evaluated in the laboratory on three adult groups (virgin females, virgin males, and fertilized, nongravid females) of the German cockroach, Blattella germanica (L.), through ingestion of treated bait. Noviflumuron caused significant ovicidal effects at concentrations ranging from 10 to 5,000 ppm after 5-d feeding exposure to virgin and fertilized females. Untreated females produced little or no viable oothecae when mated with virgin males that had previously ingested bait (5-d exposure) with 1,000 ppm or 5,000 ppm noviflumuron. The highest tested concentration of noviflumuron (5,000 ppm) caused 100% ovicidal activity through two ovarian cycles for all three adult groups. Noviflumuron seems to have broader ovicidal activity against B. germanica than reported for other benzoylphenylurea insecticides and can potentially impact cockroach populations through a combination of nymphal mortality and ovicidal activity.
