The toxicity of seven pesticides belonging to different chemical groups asmetaldehyde, abamectin, methomyl, profenofos,copper hydroxyl, chlorfenapyr and imidaclopridby using three different methodsas DLL (Dipping lettuce leaves), BBMB (Baits of bran with methylene blue) and BBM (Baits of bran with molasses) against land snails, M. obstracta under l...

The present work was aimed to identify of terrestrial gastropods species in Sohag Governorate during 2014/2015 season. The Results showed that found first record of two species of land snails, Monachaobstracta (Montagu), and Eobaniavermiculata (Muller) in the study areas. These results to be used in the development of a future plan in effective str...

Eight insecticides used in the present study were chloropyriphose, methomyl, lambada cyhalothrine, imidacolpyrid, abamectin, chlorfenapyr, chlorantraniliprole, and emamectin benzoate representing different insecticides with different modes of action were chosen to evaluate their toxicity against the tomato leaf miner, T. absoluta under laboratory a...

Since databases are the primary repositories of information for today’s organizations and governments, database security has become critically important. Introducing the concept of multilevel security in relational databases, this book provides a comparative study of the various models that support multilevel security policies in the relational dat...

This study was designed to determine pesticide residues in blood, evaluate its effect on biochemical parameters and assess adverse health effects in farmers, pesticide market-workers and pesticide sprayworkers. The level of awareness or knowledge about precautionary measures for pesticides safety was also assessed. The field survey indicated that 4...

This study was designed to determine pesticide residues in blood and establish their correlation with biochemical markers for the assessment of adverse health effects on farmers and market-and spray-workers. The level of awareness or knowledge about precautionary measures for pesticides safety was also assessed. The field survey indicated that 40.0...

Abstract: Ökologische Studien zum Auftreten und zur Bekämpfung der Fritfliege (Oscinella frit (L.) in Sommerweizen in Mitteldeutschland Die Fritfliege (Oscinella frit (L.) kann im Sommerweizen beträchtliche Schäden an den Jungpflanzen verursachen Zur Überwachung des Auftretens kamen Farbschalen zum Einsatz. Das Schadauftreten der Halmfliege wurde a...

This study aimed to throw some light on the risks of re-used agricultural drainage water to irrigate some crops. So, pesticide residues and heavy metal concentrations were determined in water and sediment samples collected from exchange bank, as well as, in soil and plant grown surrounding it. The most irrigation water of this area comes from this...

Insect damage induces chemical changes in plants, and frequently these changes are part of a defensive response to the insect injury. Induced resistance was activated in winter wheat using a foliar application of synthetic jasmonic acid. Field trials were conducted to observe effects of jasmonic acid application on some wheat insects. Two wheat cul...

Two plants, i.e. Anthemis melanopodia and Artemesia monosperma were tested against the 4 th instars larvae of S podoptera littoralis (Boisd.) under laboratory conditions. Four crude extracts (Hexane, Chloroform, Ethyl acetate and Ethanol) from each of the two plants used were evaluated by two different technique, i.e. residual films and dipping. Re...

The efficacy of range of compounds: three botanical insecticides (NeemAzal T/S, Trifolio S-forte and an extract of Quassia amara L.) and two pyrethroid insecticides, lambda-cyhalo-thrin (Karate 9.4% S.C) and deltamethrin (Decis 2.8% E.C.) were evaluated to control Rhopalosiphum padi (L.) and Metopolophium dirhodum (Wlk.). Different concentrations w...

The present investigation was carried out to study the chemical analysis of the mucus of three common land snails, Eobania vermiculata, Theba pisana and Monacha obstructa, and identification of the chemical compositions by using GC-MS. Results revealed that several variations in composition were observed between all species. Oxime, methoxy-phenyl a...

Field experiments were carried out at the experimental farm of the Faculty of Agriculture, Sohag, South Valley University during two successive seasons, 2002 and 2003, to study the relative susceptibility of some maize and sorghum varieties to infestation by greater sugar cane borers, Sesamia cretica L., and the effect of chemical insecticide (meth...

The efficacy of range of compounds: three botanical insecti-cides (NeemAzal T/S, Trifolio S-forte and an extract of Quassia amara L.) and two pyrethroid insecticides, lambda-cyhalo-thrin (Karate 9.4% S.C) and deltamethrin (Decis 2.8% E.C.) were evaluated to control Rhopalosiphum padi (L.) and Meto-polophium dirhodum (Wlk.). Different concentrations...

This monitoring study of 40 samples of cow's milk collected from different locations at Gharbia Governorate during the four different seasons of the years 2005-2006, was conducted to determine the contamination levels of seven pesticide residues including four organophosphorus (chlorpyrifos, diazinon, dimethoate and malathion) and three synthetic p...

Organophosphorus insecticides (OPs) exert their toxic effect through inhibition of acetylcholinesterase (AchE). In addition, accumulated evidences indicated that oxidative stress involved in OPs neurotoxicity and cytotoxicity. However, the mechanism underlay OPs induces oxidative stress still so far unclear. Recent reports were focused on the role...
