Abstract Fopius vandenboschi (Fullaway) is one of the natural enemies of oriental fruit flies in genus Bactrocera. It is a koinobiont solitary endoparasitoid that parasitizes first and second instars of oriental fruit flies. The advantages of this parasitoid are the ability to parasitize several host species and the length of female longevity. Reproductive biology of F. vandenboschi in this research showed that it produced average 21.0±13.4 offspring per female, equivalent to net reproductive rate of 8.4 female offspring per generation. The sex ratio is equal to 0.6 : 0.4 (♂ : ♀) and the mean generation time of is 22.5 days. These results can be applied for massrearing production of F. vandenboschi for inoculative and inundative release to enhance management populations of Bactrocera fruit fly pest in Thailand.

Abstract This research is in the sequence of the innovative utilization from a previous study on developing standard food recipes utilising Riceberry rice as the key ingredient under the context of the communities of Uttaradit province, Thailand along with the context of the ASEAN Community. The 10 standard recipes from the previous study were used in real commercialisation that aimed to promote the utilisation of local food raw materials of Uttaradit province, to increase the competitiveness of local products in the ASEAN Community’s market, and to promote commercialisation and tourism. The recipes were tested on sensory acceptance evaluation with 100 tourist samples and nutritional values assessment. The evaluation data were used to indicate the potential of the recipes to meet tourists’ satisfaction, which was eventually used together with the recipes’ nutritional data as the reference for the consideration of and selection for one month of real commercialised trial testing by seven food business entrepreneurs in Uttaradit province. After finishing the commercialised test, the food business entrepreneurs evaluated the appropriateness of the recipes to use for real commercialisation. The result of the average sensory acceptance evaluation scored on all 10 recipes using a 5-point hedonic scale evaluation form indicated that, all 10 recipes were accepted by the tourists and had the potential to be utilised for serving to tourists. The seven food business entrepreneurs selected four out of the 10 recipes for the commercialised test according to the reference data of each recipe provided for their consideration, flexibility, convenience and capability to adopt the recipes. The reasons that the entrepreneurs selected only four recipes were because of their consideration on the available raw materials during the testing period, their capability to cook the food according to the instruction of the recipes, and the conforming of the theme of the recipes to their business theme that mostly sold healthy food. The results of the recipes’ appropriateness for real commercialisation using a Likert-type scale appropriateness evaluation form have shown that the selected recipes were appropriate for use in a real commercialisation situation.

Abstract Lime juice powder was developed with 20% of combined maltodextrin/gum Arabic at a ratio of 4:1. A high shear homogenization was applied to encapsulate phytochemical compounds before spray drying with the purpose of protecting bioactive compounds from thermal degradation. The effect of high shear homogenization on physicochemical properties and antioxidant activity of spray-dried lime powder was studied. The particle size, morphology, moisture content, color, solubility, hygroscopicity, ascorbic acid, total polyphenol and flavonoid contents, and antioxidant activity of the spray-dried powder undergoing the homogenization were compared with those of the non-homogenized powder. The higher yield (30%) was obtained in the homogenized powder compared with the control (28%) with no significant difference. The average particle diameter of the homogenized powder was 0.1-4 micrometers, smaller than 18-26 micrometers of the untreated powder. Morphological study revealed that the powder without homogenization was densely packed compared with the homogenized powder. Moisture content of homogenized powder and that of the particles without homogenization were 3.91% and 5.42%, respectively. Higher solubility and less hygroscopicity values and color after spray drying were observed in reconstituted lime powder with high shear homogenization. Folin-Ciocalteu and aluminum trichloride (AlCl3) assays were used to determine total phenolic and flavonoid compounds, respectively. 2,2-diphenyl-1-picryl hydrazyle-hydrate (DPPH) assay was used to determine total antioxidant activity of the powders. The retention of ascorbic acid and total phenolic contents, and antioxidant activity was significantly better in the homogenized powder, but not the flavonoid contents. The antioxidant activity derived from total phytochemical compounds in the treated powder was preserved by the homogenization before spray drying. This study indicated that the application of high shear homogenization with combined drying agent before spray drying could prevent phytochemical compounds in lime from thermal degradation.

Abstract An approximate confidence interval for the ratio of bivariate normal means with a known coefficient of variation is proposed in this paper. This application has the area of bioassay and bioequivalence when a scientist knows the coefficient of variation of a control group. The proposed confidence interval is based on the approximated expectation and variance of the estimator by the Taylor series expansion. A Monte Carlo simulation study was conducted to compare the performance of the proposed confidence interval with the existing confidence interval. The results showed that the simulation is considered confidence interval and the estimated coverage probabilities close to the nominal confidence level for large sample sizes. The estimated coverage probabilities of the existing confidence interval are over estimated for all situations. In addition, the expected lengths of the proposed confidence interval are shorter than those of the existing confidence interval in all circumstances. When the sample size increases, the expected length become shorter. Therefore, our confidence interval presented in this paper performs well in terms of estimated coverage probability and the expected length in considering the simulation results. A comparison of the confidence intervals is also illustrated using an empirical application.

Abstract The burning of massive amount of fire crackers on the evening(s) of a nation-wide celebrated festival called ‘Diwali’ in India, gives rise to a remarkably high concentration of criteria air pollutants and it is of utmost importance to investigate the impact of such high loads originated during a relatively shorter time span in a mega-city like Delhi where the situation of ambient air quality has already been alarming almost through-out the year. In view of the same, the present study analyzes available concentration data during this festival’s night for five criteria pollutants namely PM10, PM2.5, SO2, NO2, and CO along with NH3 at six key locations of Delhi. Following the analysis, PM10 concentration in Anand Vihar during nighttime of Diwali was reported to be ~8 times higher than the 24-hr values prescribed by National Ambient Air Quality Standards (NAAQS). On the other hand, the same at IGI airport was recorded lowest even though about 3.5 times that of the guiding standard. PM2.5 concentrations were reported as highest and lowest at R.K. Puram and Civil lines respectively, in both the cases quite exceeding the comparable standard values. Interestingly, remaining criteria pollutants, namely, SO2 NO2 and CO along with NH3 measured in 2015 showed no values in excess of corresponding 24-hrs guidelines, thereby reporting a better scenario compared to previous years. Further, the extensive use of firecrackers during Diwali festival leads to substantial increase in air pollutants necessitating special measures to control.

Abstract The research focuses on an insurance model controlled by proportional reinsurance in the finite-time surplus process with an equalized interatrial time. We prove the existence of the maximal retention level for independent and identically distributed claim processes under α-regulation, i.e., a model where the insurance company has to manage the probability of insolvency to be at most α. In addition, we illustrate the maximal retention level for exponential claims by applying the bisection technique.

Abstract This paper proposes an extend mixture inverse Gaussian (EMIG) distribution which is mixed between the inverse Gaussian distribution and the length biased inverse Gaussian (LBIG) distribution. The Birnbaum-Saunders (BS) distribution and LBIG distribution are presented as special cases of the EMIG distribution. The properties of this distribution are discussed which include the shapes of the probability density functions, distribution functions survival functions and hazard rate functions, mean and variance. The EMIG has two parameters and it is shown that maximum likelihood estimation (MLE) can be obtained by solving equation. An application of the model to a real data set is analyzed using the new distribution, which shows that the EMIG distribution can be used quite effectively in analyzing real data by using Akaike’s information criterion (AIC) statistics and goodness of fit tests.

Abstract In Sri Lanka, presently used landslide hazard zonation (LHZ) map which was developed by National Building and Research Organization (NBRO) is based entirely on geological, geomorphological and hydrological factors. As development expands into unstable hill slope areas under the pressures of increasing population and urbanization, human activities such as deforestation or excavation of slopes for road cuts and building sites, etc., have become important triggers for landslide occurrence. The present study was undertaken in highly urbanized Kandy Municipal Council (KMC) area in Sri Lanka. Main objective of the study was to validate the existing LHZ map with current active landslides and the improvement of the LHZ map for further use for management purposes. Validation of the existing LHZ map shows lowest percentage of landslide occurrence in the landslides most likely to occur zone and highest in the landslides are to be expected zone. To evaluate this situation building density and transport lines were used. The relationship between building density and landslide occurrence was 97.1% and the relationship between distance from transport lines and landslide occurrence was 88.3% till 50 m. An improved LHZ map was developed including the effect of building density and distance from transport lines using frequency ratio method and improved LHZ map has an accuracy of 98.5%.

Abstract The present study was carried out with a specific objective to study postharvest spoilage of Lobhiya(Vigna unguiculata) seeds contaminated with Aspergillus flavus. Infected seeds were collected and cultured on potato dextroseagar(PDA) media, at 25±2 °C.Aspergillus flavus isolates were primarily characterized by its morphological and microscopic characteristics. Collected fungal isolates were also screened for their afaltoxigenic nature on preliminary basis and at molecular level.For preliminary screening, 5 mm disc of fungal culture was soaked with few drops of liquid ammonia. Color change from yellow pigment to plum - red with different intensities showed the mycotoxic nature of the fungus. DNA from fungal isolates was isolated and amplified using PCR with aflatoxin specific primers, apa - 2, ver - 1 and omt-1. Amplicons of 1032 bp, 895 bp and 596 bp were obtained in most of the isolates regardless of primer set used which was useful to differentiate between mycotoxic and nontoxic isolates of A.flavus. The isolation of aflatoxigenic strains of A.flavus during post - harvest period of lobhiya seeds raise a serious concern over the quality of seeds and a threat to heath of consumers. It was concluded that Aspergillus flavus is responsible for postharvest spolilage of Lobhiya(Vigna unguiculata). Keywords Vigna unguiculata (L.)

Abstract A trial of the 2,300-2,800 Hz band of frequency in sound waves were made more intense in decibels (dB), similar to a firecracker or firecracker ball was made for use of the local people to dislodge and/or obstruct wild elephants from agricultural areas (pineapple plantations) within Kui Buri District, Prachuap Khiri Khan Province, Thailand. The 3 point source was checked between 10 -50 meters, sound sources to the elephants in distances and loudness are as discussed later; firecracker balls were 151, 142, 138, 128, 119 decibels (dB), firecrackers were 99, 95, 91, 85, 72 dB, and the frequency of the sound waves (2,800 Hz) were 85, 80, 74, 70, 62 dB, respectively. The results can be analyzed through the laboratory and fundamentals of sound wave, anatomy and physiology of mammals, including comparisons to the standard sound intensities of the Acoustical Society of America (ASA). The energy and pressure of firecracker ball is strong and were transferred into some auditory mechanisms and behaviors of wild elephants. As a consequence, the elephant’s auditory mechanism has been affected from the energy and pressure; at least 1 individual of wild elephant had shown sensorineural hearing loss in the case study, their behavior became more aggressive and more easily angered.

Abstract This research is quantitative and qualitative explorative research. The purposes of this research was 1) to study bird species, feeding behavior, abundance and status in study area 2) to study activities in utilization of birds in the study site. The data was obtained by interviewing the owners of fruit gardens and field surveys of bird species, activities of birds in habitat utilization in three kinds of organic fruit gardens namely; lychee garden, coconut garden, and pomelo garden in Bang Nang Li Sub-district, Amphawa District, Samut Songkram Province from October 2012 – September 2013. The result of bird survey in 3 gardens found 31 families and 61 species of birds. 52 bird species were found the most in organic pomelo gardens. In feeding habitats, insectivorous, piscivorous, granivorous, nectrivorous birds and aquatic invertebrate feeding birds were found. Abundance level of birds in organic fruit gardens was at level 5. 23 bird species were frequently found. 43 bird species were found in November because migratory birds came to utilize the study site. According to the status of bird species, 48 resident bird species, 6 resident and 7 migrant bird species were found in organic fruit gardens. The birds’ activities in fruit gardens were feeding and nesting. Keywords Samut Songkram Province, Fruit gardens, Bird diversity.
