| Title: Laboratory and field studies on the effect of molinate , clomazone , and thiobencarb on nontarget aquatic invertebrates .
| | Author: Burdett AS Stevens MM Macmillan DL .
| | Journal: Environ . Toxicol . Chem . Citation: V : 20 ( 10 ) P : 2229-36 Year: 2001 Type: ARTICLE | | Literature: oryza Field: abstract Doc ID: pub11596755 Accession (PMID): 11596755 | | Abstract: The midge Chironomus tepperi was used in laboratory experiments to assess the relative toxicity of formulated molinate , clomazone , and thiobencarb , three herbicides used in Australian rice crops .
Static bioassays were initiated with first-instar larvae at herbicide concentrations between 0 . 0625 and 2 times the anticipated field concentrations ( AFCs ) expected from the registered application rates .
Adult emergence success , development time , and wing length were used as indices of the effect of each herbicide .
Clomazone had no effect on any parameters at concentrations up to 0 . 288 mg/L ( p > 0 . 05 ) .
Molinate significantly increased development time at concentrations equivalent to the AFC ( 3 . 6 mg/L ) and above ( p < 0 . 05 ) .
Thiobencarb reduced emergence success of adult C tepperi at 0 . 0625 times the AFC ( 0 . 1875 mg/L ) as well as decreasing male adult size and increasing development time for males and females at 0 . 125 times the AFC ( p < 0 . 05 ) .
Nontarget effects of the herbicides on aquatic invertebrate communities were assessed in shallow experimental ponds using commercial application rates .
One week after treatment , only thiobencarb had a significant effect , suppressing populations of chironomids , calanoids , and cyclopoids ( p < 0 . 05 ) .
Four weeks later , all populations had recovered , equaling or exceeding control densities .

| Title: Arsenic groundwater contamination and sufferings of people in North 24-Parganas , one of the nine arsenic affected districts of West Bengal , India .
| | Author: Rahman MM Mandal BK Chowdhury TR Sengupta MK Chowdhury UK Lodh D Chanda CR Basu GK Mukherjee SC Saha KC Chakraborti D | | Journal: Citation: V : 38 ( 1 ) P : 25-59 Year: 2003 Type: ARTICLE | | Literature: oryza Field: abstract Doc ID: pub12635818 Accession (PMID): 12635818 | | Abstract: To understand the magnitude of the arsenic calamity in West Bengal , a detailed study spanning 7 years was made in North 24-Parganas , one of the nine arsenic affected districts .
Area and population of North 24-Parganas district are 4093 . 82 sq . km and 7 . 3 million , respectively .
Fourty eight thousand and thirty water samples were analyzed from hand tubewells of North 24-Parganas in use for drinking , cooking and 29 . 2% of the tubewells were found to have arsenic above 50 microg/L , the maximum permissible limit of World Health Organization ( WHO ) and 52 . 8% have arsenic above 10 microg/L , WHO recommended value of arsenic in drinking water .
Out of the 22 blocks of North 24-Parganas , in 20 blocks arsenic has been found above the maximum permissible limit and so far in 16 blocks people have been identified as suffering from arsenical skin lesions .
From the generated data , it is estimated that about 2 . 0 million and 1 . 0 million people are drinking arsenic contaminated water above 10 microg/L and 50 microg/L level , respectively in North 24-Parganas alone .
So far , in our preliminary study 33 , 000 people have been examined at random from arsenic affected villages in North 24-Parganas and 2274 people have been registered with arsenical skin lesions .
Extrapolation of the available data indicates about 0 . 1 million people may be suffering from arsenical skin lesions from North 24-Parganas alone .
A sum of 21 , 000 hair , nail , and urine samples analyses from arsenic affected villages show 56% , 80% , and 87% people have arsenic in biological specimen more than normal/toxic ( hair ) level , respectively .
Thus , many may be subclinically affected .
Due to use of arsenic contaminated groundwater for agricultural irrigation , rice and vegetable are getting arsenic contaminated .
Hence there is an additional arsenic burden from food chain .
People from arsenic affected villages are also suffering from arsenical neuropathy .
A followup study indicates that many of the victims suffering from severe arsenical skin lesions for several years are now suffering from cancer or have already died of cancer .

Citation: V : 29 ( 1 ) P : 177-91 Year: 2004 Type: ARTICLE | | Literature: oryza Field: abstract Doc ID: pub15266755 Accession (PMID): 15266755 | | Abstract: In late 1999 and early 2000 , an outbreak of hantavirus pulmonary syndrome ( HPS ) occurred in and around Los Santos , on the Azuero Peninsula of southwestern PanamE This HPS episode , resulting in 22% case fatality , was linked to the Costa Rican pigmy rice rat , Oligoryzomys fulvescens costaricensis , which harbored a then undescribed hantavirus , Choclo virus .
In addition , Cherries cane rat , Zygodontomys brevicauda cherriei , was identified as carrying a distinct hantavirus , Calabazo virus with no known pathogenicity to humans .
Herein we present the ecological results of the outbreak investigations in the Azuero region .
A total of 164 animals were captured , of which 126 were potential small , non-volant mammal hosts of a hantavirus : rodents in the family Muridae .
There were significant differences in small mammal community structure between case sites and a negative control site .
Differences were manifest in ecological measures of species diversity and in species evenness and heterogeneity measures , as indicated by Pairwise Euclidian distances and Morisita indices of community similarity .
Our analyses suggest that human activities ( ie , deforestation for cattle ranching ) coupled with environmental factors ( ie , increased precipitation ) may have synergistically coalesced for an increased risk of HPS to area residents .

| Title: [ Medical pots of Yakushi Buddha in Japan ] | | Author: Okuda J Noro Y Ito S | | Journal: Citation: V : 53 ( 345 ) P : 7-32 Year: Type: ARTICLE | | Literature: oryza Field: abstract Doc ID: pub16021752 Accession (PMID): 16021752 | | Abstract: The origin of Yakushi buddha ( Bhaisajyaguru in Sanscrit , buddha of healing ) is not clearly known .
It has been proposed the original statue of Yakushi buddha may have been conceived from Varna , a god in Brahminism , believed to be a god of justice who possessed medicines and prolonged life .
It is believed that Yakushi buddha appeared in Japan when the buddhism was imported from Korea and China in VI century , Yakushi buddha was believed more profoundly in Japan , compared with Korea and China . The reasons are probably as follows : Yakushi buddha is buddha of healing , Emperor Temmu ( 672-685 ) built Yakushi-ji temple in Nara , Emperor Shomu ( 724-749 ) built Kokubun-ji temples at principal towns .
The principal statues of buddha in these temples are Yakushi buddha .
In Japan , there are 252 Yakushi Buddha statues in Buddhistical Temples , which are listed in Important Cultural Property including 14 National Treasures .
Belief in Yakushi Buddha was especially prevalent from the 7th to the 13th centuries in Japan .
The oldest wooden Yakushi Buddha statue is in the Horin-ji temple in Nara .
Among the 252 Yakushi Buddha statues , 224 are in wood , 15 are in copper , 6 are in picture and etc 212 ( 84 , 1% ) have medicinal pots ( or rarely , a bowl ) on the palm of left hand .
However , these medicinal containers are wooden blocks .
Very recently , it was found that Yakushi Buddha statue in the Suho-Kokubun-ji temple ( Yamaguchi Prefecture , Japan ) has a medicinal pot on the palm of the left hand in which an offering ( 220 g materials ) was found .
The date on the reverse side of lid places the offering at October 12 , 1699 .
The offering is composed of five cereals ( rice , barley , wheat , soybean , adzuki bean ) , five medicinal plants ( Acori Graminei , Acori Calami , Radix Ginseng , Flos Caryophylli , Lignum Santali Albi ) , and five minerals ( rock crystals , purple and blue glasse , CaCO3 , particles , silver and golden foils ) .

| Title: A database of PCR primers for the chloroplast genomes of higher plants .
| | Author: Heinze B | | Journal: Plant Methods Citation: V : 3 ( ) P : 4 Year: Type: ARTICLE | | Literature: oryza Field: abstract Doc ID: pub17326828 Accession (PMID): 17326828 | | Abstract: ABSTRACT : BACKGROUND : Chloroplast genomes evolve slowly and many primers for PCR amplification and analysis of chloroplast sequences can be used across a wide array of genera .
In some cases universal primers have been designed for the purpose of working across species boundaries .
However , the essential information on these primer sequences is scattered throughout the literature .
RESULTS : A database is presented here which assembles published primer information for chloroplast DNA .
Additional primers were designed to fill gaps where little or no primer information could be found .
Amplicons are either the genes themselves ( typically useful in studies of sequence variation in higher-order phylogeny ) or they are spacers , introns , and intergenic regions ( for studies of phylogeographic patterns within and among species ) .
The current list of generic primers consists of more than 700 sequences .
Wherever possible , we give the locations of the primers in the thirteen fully sequenced chloroplast genomes ( Nicotiana tabacum , Atropa belladonna , Spinacia oleracea , Arabidopsis thaliana , Populus trichocarpa , Oryza sativa , Pinus thunbergii , Marchantia polymorpha , Zea mays , Oenothera elata , Acorus calamus , Eucalyptus globulus , Medicago trunculata ) .
CONCLUSION : The database described here is designed to serve as a resource for researchers who are venturing into the study of poorly described chloroplast genomes , whether for large or small-scale DNA sequencing projects , to study molecular variation or to investigate chloroplast evolution .

| Title: Suitability of five species of stored-product insects as hosts for development and reproduction of the parasitoid Anisopteromalus calandrae ( Hymenoptera : Pteromalidae ) .
| | Author: Ghimire MN Phillips TW | | Journal: J Econ Entomol Citation: V : 100 P : 1732-9 Year: 2007 Type: MEDLINE | | Literature: oryza Field: abstract Doc ID: pub17972654 Accession (PMID): 17972654 | | Abstract: We investigated the ability of two populations of Anisopteromalus calandrae ( Hymenoptera : Pteromalidae ) , to parasitize and develop on late instars of five different stored-product insects that typically complete their development inside seeds of grain or legume species or other dry commodity .
The host species were the cigarette beetle , Lasioderma serricorne ( F ) ; cowpea weevil , Callosobruchus maculatus ( F ) ; rice weevil , Sitophilus oryzae ( L ) ; lesser grain borer , Rhyzopertha dominica ( F ) ; and Angoumois grain moth , Sitotroga cerealella ( Olivier ) .
Experiments were conducted in the laboratory in a no-choice design by using petri dishes ( 15 by 100 mm ) as experimental arenas with 20 host larvae .
A calandrae females from populations originating in Georgia ( GA ) and Oklahoma ( OK ) were introduced singly into experimental arenas and allowed to sting and oviposit for 24 h .
Parasitism by the OK population was greater than that for the GA population across all hosts .
However , no or very low parasitism was found on Angoumois grain moth for either population in this experiment .
The highest number of parasitoid progeny was recorded on cowpea weevil ( 15 . 9 ) followed by rice weevil ( 11 . 5 ) and cigarette beetle ( 10 . 8 ) for the OK population .
A similar trend was observed in the GA population .
The highest proportion of female progeny was produced on cowpea weevil ( 73 . 0% ) by the OK population .
Conversely , a higher proportion of female progeny was produced on rice weevil ( 64 . 6% ) by the GA population than produced by the OK population .
Parasitoid adults were significantly larger and heavier when they developed on cowpea weevil irrespective of parasitoid population .
The possible application of these results for biological control of stored-product insects is discussed .

In choice experiments , 20 wheat kernels infested by rice weevil and 20 by lesser grain borer were placed randomly in petri dish ( 15 by 100 mm ) arenas .
In no-choice experiments , 10 host-infested wheat kernels , either with rice weevils or with lesser grain borers , were mixed thoroughly in 500 g of uninfested wheat placed in a 0 . 945-liter glass jar ( 75 by 170 mm ) arenas .
A calandrae females from a laboratory and field populations that were experienced with host larvae or naive were introduced singly into each experimental arena and allowed to sting and oviposit for 24 h .
An oviposition experience with rice weevil or lesser grain borer had a stronger effect on host preference in choice experiments compared with experiments with naive wasps .
Host-finding and parasitism rates were increased by prior experience with rice weevils in no-choice experiments .
A calandrae females clearly preferred rice weevil larvae for parasitization over larvae of lesser grain borer regardless of parasitoid population or prior experience .
Also , A calandrae females chose rice weevil larvae for producing female progeny and lesser grain borer for male progeny in choice experiments .
The implications of the results of this study are discussed in relation to host preference and the selection of parasitoid populations for biological control programs in stored grains .

| Title: Effects of biological control of rice weevil by Anisopteromalus calandrae with a population of two Aspergillus spp .
| | Author: Yoon EY Nam Y Ryoo MI | | Journal: Environ Entomol Citation: V : 38 P : 121-8 Year: 2009 Type: MEDLINE | | Literature: oryza Field: abstract Doc ID: pub19791605 Accession (PMID): 19791605 | | Abstract: In this study , we assessed the interaction occurring between the rice weevil and two storage molds ( Aspergillus candidus Link and Aspergillus niger Van Tiegem ) that prefer different moisture regimens under rice storage conditions .
Rice weevil induced rapid population growth in both of the storage molds .
The colony forming units ( CFUs ) of A candidus and A niger peaked at 10 ( 9 . 00 +/- 0 . 02 ) and 10 ( 7 . 72 +/- 0 . 03 ) /g , respectively .
All of the rice grains were infested with the molds and eventually deteriorated ; in the jars infested with A candidus , no living weevils were found after 135 d .
Suppression of the rice weevil by its larval parasitoid , Anisopteromalus calandrae ( Howard ) , significantly retarded the growth of A candidus but completely halted the growth of A niger , which was replaced by xerophyllic molds including Aspergillus penicilloides Spegazzini and Wallemia sebi ( Fries ) .
Regression analyses showed that the total number of weevils was a significant factor explaining grain moisture content , which was in turn a significant factor in the growth of both mold species .
The growth of A niger was dependent on the grain moisture content ( r2 = 0 . 52 ) , thereby suggesting that the growth of A niger was caused primarily by activity of the rice weevil and the resulting increased grain moisture content .
However , 27% of the growth of A candidus was explained by grain moisture contents , suggesting that a factor other than the grain moisture content may also affect its growth .
Suppression of rice weevil by A calandrae could induce an A candidus-dominant molds community , which would be a factor for consideration in biological control program .
