The Toxicity of Bran Baits , Formulated with Carbaryl , Chlorpyrifos and Dimethoate , on Yellow Mealworms ( Tenebrio molitor L
Laboratory feeding trials were conducted to assess the comparative impact of registered and new unregistered insecticide-treated bran baits on nontarget epigcal arthropods. Yellow mealworm beetles and larvae (Tcllebrio molitor, L.) (8 surrogate, surface-dwelling tenebrionid) were individually housed in containers and exposed to five different dosages (quantities) of bran bait treated with three...
متن کاملAcute Toxicity and Behavioural Responses of Heteropneustes Fossilis to an Organophosphate Insecticide, Dimethoate
Static renewal evaluation of the acute toxicity of an organophosphate pesticide, dimethoate against the freshwater fish H. fossilis was conducted in the laboratory. H. fossilis showed behavioural changes against dimethoate intoxication. There were increased opercular movement, sluggish, lethargic and abnormal swimming, loss of buoyancy and muscular tetany. The treated fishes also showed fading ...
متن کاملAcute Toxicity and Behavioral Responses of Common Carp Cyprinus carpio (Linn.) To an Organophosphate (Dimethoate)
Dimethoate, a broad spectrum OP insecticide is a potential toxic pollutant, adversely affecting the fauna of aquatic ecosystem. The aim of present study was to assess the acute toxicity of dimethoate on fingerlings of common carp, Cyprinus carpio. The fingerlings were exposed to dimethoate to determine LC values for 24, 48, 72 and 96 h and to study the behavioural alterations. The mortality dat...

بسیاری از پدیده ها در جهان ما اساساً غیرخطی هستند، و توسط معادلات غیرخطی بیان شده اند. از آنجا که ظهور کامپیوترهای رقمی با عملکرد بالا، حل مسایل خطی را آسان تر می کند. با این حال، به طور کلی به دست آوردن جوابهای دقیق از مسایل غیرخطی دشوار است. روش عددی، به طور کلی محاسبه پیچیده مسایل غیرخطی را اداره می کند. با این حال، دادن نقاط به یک منحنی و به دست آوردن منحنی کامل که اغلب پرهزینه و ...
15 صفحه اولEnvironmental Fate of Mancozeb
Mancozeb is one member of ethylenebisdiothiocarbamate (EBDC) fungicides. This compound has a negligible vapor pressure, therefore it has a low potential to volatilize into the air. In water, mancozeb can be quickly hydrolyzed with a half-life of less than 2 days. The identified hydrolysis degradates are ethylenethiourea (ETU), ethyleneurea (EU) and ethylene bisisothiocyanate sulfide (EBIS). Man...
