Essential oil extracted from the leaves of Myrtle, Myrtus communis L. (Myrtaceae)was tested in vitro for volatile toxicity against two stored-product insects (Tribolium confusum and Callosobruchus maculatus). The chemical composition of the plant oil was examined by gas chromatography-mass spectrometry (GC-MS). The major oil components were α-pinene (10.4%), α- Terpineol (10.1%), linalool (9.0%...

Efficient task partitioning plays a crucial role in achieving high performance at multiprocessor platforms. This paper addresses the problem of energy-aware static partitioning of periodic realtime tasks on heterogeneous multiprocessor platforms. A Particle Swarm Optimization variant based on Min-min technique for task partitioning is proposed. The proposed approach aims to minimize the overall...

Abstract Archaeological sites and structures suffer from several factors of deterioration. The present survey focuses on the biodeterioration by plants, which is not less important than rest deterioration factors; moreover, in many cases, it leads to their occurrence. Despite importance plants our lives aesthetic appearance around stone monuments, they pose a threat survival. Therefore, necessa...

Excessive use of pesticides has led to increasing concern about undesirable effects on human health and the environment. Imidacloprid is an internationally used neonicotinoid insecticide due its significant toxicity insects. Its residues may reach food chain, which important for examining potentially harmful properties imidacloprid exposure. The current study aimed characterize histopathologica...

the invertebrate communities of the northern chilean rivers are characterised by their marked endemism andspecificity of their community structure in different basins. the river systems located in the atacama desert are endorheicand are affected by the rainy period of january-february commonly known as the “bolivian winter“. the present study isthe first report on the observations of arthropods...

Background: Nowadays stored–product insect pests are controlled by pesticides and chemical fumigant compounds. The continueous use of chemical pesticides is harmful for non–target creatures specially humans and other mammals. Beside they polluted the environment. Objective: Accoring to the studies, the essential oil of Labiatae plants have insecticidal activity against some pests. In this st...

abstractthe oldest method for the managing of the illness is the use of medicinal plants. the use of herbal products as the first choice in self-treatment of minor conditions continues to expand rapidly across iran. this makes the safety of herbal products an important public health issue.pesticides are used widely in agriculture to increase the production by controlling the harmful insects and...

cotton (gossypium hirsutum l.)  is an important fiber crop in iran, cultivated on 150000-200000 ha of land.  in iran the estimated loss due to the insect pest is more than 30%. traditionally, pests are controlled by 10-12 times spraying per growing season of environmentally harmful chemical insecticides (e.g. endosulfan and/or methosystox). in order to produce transgenic cotton resistance to in...
