Electron Paramagnetic Resonance Imaging (EPRI) can provide insight into in vivo anatomic and functional imaging of free radicals and paramagnetic molecules and their role in disease in small animal models. However, there is a need to expedite the data acquisition and post-processing to enable new EPRI applications. While previous work has used a fixed-rate master clock to pace all A/D and D/A c...
This study was carried out by visiting the designated areas at least twice between months of April and October each year 2014 2016 to determine phytophagous Syrphidae species in Antalya (Korkuteli), Afyonkarahisar (Dazkırı, Dinar), Burdur, Isparta (all districts), Konya (Beyşehir) located within borders Lakes Region. Adult syrphid individuals were collected from trees, shrubs, herbaceous plants...
The tarnished plant bug, Lygus lineolaris (Palisot de Beauvois) (Hemiptera: Miridae), has become the primary target of foliar insecticides in cotton, Gossypium hirsutum L., throughout the Midsouth over the past several years. This prompted a reevaluation of existing action thresholds for flowering cotton under current production practices and economics. A trial was conducted at 19 locations thr...
Colaspis crinicornis Schaeffer (Coleoptera: Chrysomelidae) primarily occurs in the Great Plains, United States. Although C. crinicornis has historically been considered a non-pest and is rarely found in agricultural systems, population densities of this species have been increasing in corn, Zea mays L., and soybean, Glycine max (L.) Merrill, over the last decade in southeastern Nebraska. As par...
background: aquatic insects are very abundant and divers groups of insects that are associated with an aquatic or semiaquatic environment in one or more of their life stages. these insects have been, in some cases, well studied because they are vectors of several diseases. this is the first comprehensive faunistic study of aquatic insects from babol county. the results may provide basic data fo...
Methods for sampling ecological assemblages strive to be efficient, repeatable, and representative. Unknowingly, common methods may be limited in terms of revealing species function and so of less value for comparative studies. The global decline in pollination services has stimulated surveys of flower-visiting invertebrates, using pan traps and net sampling. We explore the relative merits of t...
Fast reconstruction of the whole Brillouin gain spectrum is experimentally demonstrated using sweep-free Brillouin optical time-domain analysis (SF-BOTDA). Strain variations with the frequencies up to 400 Hz are spectrally analyzed, achieving strain sensitivity of 1 microstrain per root Hz at a sampling rate of 5.5 kHz and a spatial resolution of 4m. The results favorably compare with fiber Bra...
Rice field ecosystem is an artificial that used in agriculture. fields Seketi Village have vegetation types of corn, sugar cane, and rice, so it will affect grasshopper diversity each vegetation. The purpose this study was to determine the grasshoppers (Caelifera) effect on rice Village. method purposive sampling direct capture, namely research by making 5 plots measuring 5m x with different pl...
curly top disease is one of the important diseases of sugar beet. spatial pattern and population variation of leafhoppers circulifer haematoceps, and c. tenellus, vectors of sugar beet curly top virus, were studied in hamadan province, iran for three years (2007- 2009). sampling was carried out at the early stage of the plant growth, in accordance with planting date for 9 weeks, in 7- 10 day in...
Morphological characteristics of Stomoxys spp. were studied and recorded for the first time in Thailand. Specimens were collected in central Thailand at Nakhon Pathom, Kanchanaburi and Saraburi Province, using Vavoua traps and sweep net. It was found that Stomoxys calcitrans (L.) was the most commonly abundant species, followed by Stomoxys sitiens Rondani, Stomoxys indica Picard and Stomoxys be...
