تأثير مثبط تكوين الكايتين Cascade في معاملة بيض الذباب المنزلي (Diptera : Muscidae) Musca domestica L.

Abstract

The current research aimed to study the effect of chitin synthesis inhibitors (Cascade), which contains the active ingredient flufenoxuron (10% DC) in the treatment of eggs of house flies Musca domestica L. Certain biological aspects and reproduction when treated with three different situations: 1 - Treatment of eggs and the nutrient media, 2 - Treatment of eggs and then transported to the media, 3 - treatment the media and transferred to eggs. The results showed that the use of concentrations 20 and 25 mg / L, the percentage of hatched eggs decreased significantly on the first and second situations and the follow-up effect of chitin synthesis inhibitors in mortalites that followed the treated stage untile emergence showed the first instar larvae that produced from egg treated for concentrations listed above and the cases of treatment referred to the first and third lost during this stage and therefore the percentage of inhibition of emergence was 100% compared with 29.21, 40.72% for the concentrations of the same at the time of the transaction the second (treatment of eggs alone) that all individuals emergence from different treatments The productivity of eggs is lower than that the treatment comparison, and that high concentrations of the article led to a decrease in the percentage of eggs to hatch and the results indicated the chitin synthesis inhibitors impact on the average length of growth stage, the amount of which increased this period increased concentrations used, for mature individuals, the average age of adult decreased with increasing concentrations of knowing that when you make the second treatment (treatment of eggs alone) do not configure chitin synthesis inhibitors significantly affected the duration of the growth of immature stages as well as the emerging adult ages.
