The concentrations 8000 , 10000 and 12000 ppm were used to know the mortalities in workers and soldiers of termite Microcerotermes diversus (Silv.) at different temperature degrees (20 , 25 , 30 , 35 + 3 o C). Lufenuron at all concentrations and temperature degrees caused a gradual mortality and the results also showed no difference in susceptibility between workers and soldiers towards toxicity of Lufenuron. Temperate had a significant effect on the speed up of incidence of mortality. Therefore , the mortality percentage reached to 100% in workers and soldiers after 28 days from treatment at temperature of 25 and 30 + 3 o C , and after 49 days at temperature of 20 and 35 + 3 o C . The second reinfestation of the same treated diet after 60 days and the third reinfestation after 90 days of treatment had shown a gradual relative decline in the percentage mortalities of termite individuals depending on the duration of exposure. Mortality percentages reached to more than 50% at the highest concentration (12000 ppm) and less than 50% at the lowest concentration (8000 ppm) at temperatures at 25 and 30 + 3 o C after 90 days from treatment. The results showed that there is a positive correlation between concentrations and mortality percentages at all temperature degrees. It could be conducted that the effective duration and persistence of Lufenuron depend on concentration , temperature and exposure time.","PeriodicalId":13790,"journal":{"name":"International Journal of Agricultural Technology","volume":"11 1","pages":"1393-1399"},"PeriodicalIF":0.0,"publicationDate":"2016-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67688061","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An insect pest, moringa moth (Noorda blitealis Walker) has become an important pest on moringa trees in Southern Rift Valley of Ethiopia. The present study was carried out to determine the distribution and damage status of moringa moth (N. bliteails) on M. stenopetala in the study areas of Konso, Derashe and Arbaminch Zuria districts of Southern Rift valley of Ethiopia. Qualitative and quantitative data of defoliation severity were collected during the periods of heavy defoliation in major and minor rainy seasons of the year 2011. The damage rating values were taken by using the Arc GIS 9.3 and Arc GIS 10.0 softwares and the SNNPR data map of Ethiopia was used to make the distribution map. The visual damage rating mean values of the trees and the defoliation percentage were determined with respect to seasonal variations, cropping systems, altitudinal differences, and host plant age differences. The extent of defoliation by moringa moth was recorded maximum during the major rainy season than minor rainy season and the reduced leaf biomass production of moringa trees (31-70%) were recorded during the month of July at the mixedcropping system condition and more than75% recorded during the months of July and December for mono-cropping system condition. Moderate to severe defoliation was recorded within the altitude range of 12001600 m. a. s. l. The leaves of old trees having large trunk and canopy size were more resistant to moringa moth attack than the leaves of younger trees that have relatively small trunk and canopy size during both the major and the minor rainy seasons. Succulent and younger leaves were grown after continuous and periodic leaf harvest, which were more susceptible for attack by moringa moth larvae than tender and older leaves which stayed for longer periods on the tree without continuous harvest. This study was helpful in identifying the gaps concerning the basic information on spacial and seasonal distribution of moringa moth in these areas of Ethiopia. Further study could be conducted on various methods of managing this pest on moringa trees and growers may have enough quantity and better quality of moringa vegetables that could be produced.","PeriodicalId":13790,"journal":{"name":"International Journal of Agricultural Technology","volume":"9 1","pages":"963-985"},"PeriodicalIF":0.0,"publicationDate":"2013-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70362012","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Heavy metals such as Pb, Zn, Cd, As etc. are one of the most toxic pollutants which show hazardous effects on all living livings. Lead is one such pollutants which disrupts the food chain and is lethal even at low concentrations. The prevailing purification technologies used for removal of contaminants from wastewater are not only very costly but causes negative impact on ecosystem subsequently. Phytoremediation, an ecofriendly technology which is both ecologically sound and economically viable is an attractive alternative to the current cleanup methods that are very expensive. This technology involves efficient use of aquatic plants to remove, detoxify or immobilize heavy metals. The purpose of this review was to assess the current state of phytoremediation as an innovative technology and to discuss its usefulness and potential in the remediation of lead contaminated water.","PeriodicalId":13790,"journal":{"name":"International Journal of Agricultural Technology","volume":"8 1","pages":"1-11"},"PeriodicalIF":0.0,"publicationDate":"2011-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.7439/IJBR.V2I7.124","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71304841","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The milk permeate contained 6.1% total solids, 4.2% lactose and 0.54% ash. The permeate was treated through several processes, heat fermentation and clarification. Strawberry and mango homogenates were prepared and stored at -20°C until use. Fruit beverages were prepared using the pretreated permeate and fruit homogenates at ratio of 3:1 (v/w). Sports drinks were chemically analyzed and organoleptically evaluated fresh and every 5 days until 15 days of storage in refrigerator. The results revealed that milk permeate was a good source the essential electrolytes such as calcium, potassium, sodium, magnesium and phosphorus which may be taken as sports drinks after normal or vigorous exercise to replace these ions. Using strawberry or mango greatly increased calcium, potassium, sodium, magnesium and phosphorus content in the prepared drink. Mango was a better source for potassium and magnesium compared to strawberry, whereas strawberry was a better source with respect to calcium and phosphorus. Sensory evaluation indicated that the two sports drinks with fruits were more acceptable than the plain control.","PeriodicalId":13790,"journal":{"name":"International Journal of Agricultural Technology","volume":"7 1","pages":"1247-1254"},"PeriodicalIF":0.0,"publicationDate":"2011-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68519267","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These parameters were deduced from the established analytical models describing the underlying principles for the crop characteristics and machine variables as factors influencing the overall machine performance of a stationary multi-crop thresher. A computer programme written in Visual Basic was used to select optimum operating performance of the threshing process in a stationary tooth-peg grain crop thresher. An IITA-popularized stationary multi-crop thresher was used to test the practical feasibility of the computer based output of the threshing process. A split -split -unit statistical design was used for data collection. The data collected were analyzed using the GENSTAT 5 statistical package with its computer programme. The results showed that graphs of data from measured thresher performance indices against the predicted data for all the established models indicated high correlation between the models and the measured data at p ≤5% significance level. The minimum energy requirements for detachment of sorghum and rice were observed at the threshing cylinder speed of 500 r/min (10.5 m/s) and 615 r/min (13.0 m/s), respectively. The combination of the threshing cylinder speed of 500 r/min (10.5 m/s) and 615 r/min (13.0 m/s) at crop moisture content of 12.8 % and 16.2 % indicated optimum threshing conditions for sorghum and rice, respectively.","PeriodicalId":13790,"journal":{"name":"International Journal of Agricultural Technology","volume":"7 1","pages":"39-56"},"PeriodicalIF":0.0,"publicationDate":"2010-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70038942","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
