Abstract
The present studies were conducted to evaluate toxic and biological effects of some formulation compounds; XenTari, Biovar, NeemAzal, (biocids) and Jojoba oil, Orange oil (oils)against cotton leafworm, Spodoptera littoralis (Boisd.). Results clear that all compounds had toxic effect on the 2ndinstar larvae of S. littoralis. Increasing the concentration of compounds and days post-treatment caused increase in larval mortality percentage. Jojoba oil had the highest mortality percentage (33, 42, 46, 47and 50%) and (41, 49, 53, 45 and 57%) after 1, 3, 5, 7 and 10 days from treatment by recommended and double recommended concentration as compared with 5% for control after 10 days. While the lowest mortality percentages were (13, 16, 18, 20 and 21%) and (19, 25, 28, 31 and 32%) recorded with Orange oil, respectively. 2nd tested instar larvae were affected more than 4nd instar larvae. These compounds showed the different effects on some aspects of S. littoralis treated as 2nd and 4th instar larvae and caused decrease in larval & pupal mortality percentage, larval & pupal weight, pupation & adult emergency percentage, deposited eggs/ female and hatchability percentages as compared with control. While, Dursban (O.P. Insecticide (showed the highest effects on these biological aspects as compared with previous all compounds.
