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...

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...

Two new electrostatic devices were developed to manage greenhouse insect pests. One was an catcher (EIC) trap small flying pests, and the other arc-discharge zapper (ADZ) kill larger insects emerging from soil beds. The EIC consisted of negatively charged insulated conductor plates (NIPs) grounded (GCPs), which alternately arrayed in parallel at defined intervals. ADZ had same framework as EIC,...

abstract during growing seasons of years 2006 & 2007, a faunistic survey on syrphidae family(diptera) in agroecosystems of neyshabor region, khorasan-e-razavi province was carried out. in this study, 3 collection methods: yellow water trap, malaise trap and sweeping net were applied. the results showed a large difference between different collection methods. specimens of 14 species collected by...

abstract during these protracted years, mankind’s main foods consist of grains-specially wheat, oats and rice. granary production and its storage have been one of the main concerns of a human being for a long time. microwave radiation as a safe insect control agent could secure high mortality rate of insect population by increasing the temperature of insects’ body and its niche. low temperature...

The observed patterns of distribution and abundance of aquatic insects indicate successful adaptations to a wide variety of habitats. To demonstrate how organisms adapt to particular niches of the freshwater community, examples of species using certain environments are presented in this chapter and the life cycle is used as a framework for describing diverse modes of coping with environmental c...

The Red Palm Weevil (RPW) is one of the major pests palms, frequently leading to plants death. Action plans and development bio/physical strategies contrast RPW diffusions are strongly recommended due serious concerns related environmental pollution insects’ resistance chemicals. In present study, we investigated morphological alterations ovaries testes in adult exposed 2.45 GHz for 5, 15, 30 s...
