Three commercially available insecticide aerosol compositions containing cyphenothrin, imiprothrin, cypermethrin, d-tetramethrin and permethrin, in various combinations and concentrations were evaluated for control of the oriental eye flies Siphunculina funicola (de Meijere) from their aggregation substrates in two villages in the Chon Buri Province, Thailand. Each aerosol produced almost compl...

This descriptive study aimed to document cigarette retailers' knowledge and behaviors about the minimum legal age of cigarette buyers, and their estimates of the proportion of children and women among cigarette buyers. The study was conducted among 70 shop attendants in Hat Yai and Chon Buri cities. A semi-structured interview method was used to collect data using open-ended and close-ended que...

The Yellow Mosaic Disease is the main constraint for decreased yield in blackgram production. Coat protein gene of Mungbean yellow mosaic virus (MYMV) has been characterized and phylogenetic tree was constructed. genomic DNA from diseased plants collected it tested it’s quality quantity using a Nanodrop. isolated subjected to polymerase chain reaction begomovirus universal primers preliminary c...

Yellow leaf curl disease in chili pepper has been reported Bali Island since the early 2012. Research was conducted to identify virus causing this and distribution Bali. Field survey carried out observe intensity collect field samples from several growing areas (Karangasem, Bangli, Tabanan, Gianyar). Begomovirus identification then by polymerase chain reaction method using universal primers SPG...

Human-mediated bioinvasions provide the opportunity to study the early stages of contact between formerly allopatric, divergent populations of a species. However, when invasive and resident populations are morphologically similar, it may be very difficult to assess their distribution in the field, as well as the extent of ecological overlap and genetic exchanges between invasive and resident po...

An investigation on the diversity of marine fungi was carried out by isolating fungi from twigs collected from several beaches in Chanthaburi, Rayong and Chon Buri provinces. Each fungus was directly isolated on half strength potato dextrose agar with 70% sea water. A total of 152 marine fungal isolates were found, comprising 26 genera and 31 species: Algialus parvus, Antennospora quadricornuta...

Maize streak virus (MSV; family Geminiviridae, genus Mastrevirus), the causal agent of maize streak disease, ranks amongst the most serious biological threats to food security in subSaharan Africa. Although five distinct MSV strains have been currently described, only one of these - MSV-A - causes severe disease in maize. Due primarily to their not being an obvious threat to agriculture, very l...

DNA γ is approximately half of the size of Begomovirus DNA. It encodes a γC1 gene that is conserved in position and size. This gene has the capacity to encode a 13 to 14 kDa protein comprising 118 amino acid residues. It has been shown earlier that γC1 protein is necessary for inducing symptoms of cotton leaf curl disease. The structure for γC1 (CLCuDγ01-Pakistan) is still unknown. Therefore, a...

Leaf samples of Solanum lycopersicum, Capsicum annuum, Cucurbita moschata, Cucurbita pepo, Sechium edule and Erythrina spp. were collected. All samples were positive for begomoviruses using polymerase chain reaction and degenerate primers. A sequence of ∼1,100 bp was obtained from the genomic component DNA-A of 14 samples. In addition, one sequence of ∼580 bp corresponding to the coat protein (...

Tomato leaf curl Bangalore virus (ToLCBV) was successfully transmitted using viruliferous whiteflies (Bemisia tabaci) to several tomato varieties and hybrids, viz. Arka vikas, Pusa ruby, Rashmi, Rakshitha and Swaraksha. Hybrid Rashmi took 100% uniform infection, which was selected for further propagation of the virus. ToLCBV was also transmitted to Nicotiana benthamiana; the rate of infection w...
