Occupational exposure of workers to pesticides: Toxicogenetics and susceptibility gene polymorphisms Genet. Mol. Biol.
Adad,Lúcia Maria de Miranda; Andrade,Heloísa Helena Rodrigues de; Kvitko,Kátia; Lehmann,Mauricio; Cavalcante,Ana Amélia de Carvalho Melo; Dihl,Rafael Rodrigues.
Farm workers are often exposed to pesticides, which are products belonging to a specific chemical group that affects the health of agricultural workers and is mostly recognized as genotoxic and carcinogenic. The exposure of workers from Piauí, Brazil, to these hazardous chemicals was assessed and cytogenetic alterations were evaluated using the buccal micronucleus assay, hematological and lipid parameters, butyrylcholinesterase (BChE) activity and genetic polymorphisms of enzymes involved in the metabolism of pesticides, such as PON1, as well as of the DNA repair system (OGG1, XRCC1 and XRCC4). Two groups of farm workers exposed to different types of pesticides were evaluated and compared to matched non-exposed control...

Parasitoides no controle biológico de Tefritídeos na amazônia brasileira. Repositório Alice
ADAIME, R..
Na Amazônia brasileira, as pesquisas sobre parasitoides de Tephritidae avançaram nos anos recentes. Estão assinaladas nove espécies de Braconidae (duas não formalmente descritas), sendo Doryctobracon areolatus (Szépligeti) e Opius bellus Gahan as mais abundantes e amplamente distribuídas. Entre os Figitidae, ocorrem quatro espécies, com predomínio de Aganaspis pelleranoi (Brèthes). Algumas espécies vegetais apresentam potencial como "multiplicadoras de parasitoides", como Spondias mombin (Anacardiaceae) e Bellucia egensis (Melastomataceae), com índices de parasitismo de até 50% dos pupários. Bellucia grossularioides (Melastomataceae) apresenta parasitismo de até 20%, porém torna-se relevante em função de sua elevada abundância e ampla distribuição....

Adaime,Ricardo; Sousa,Maria do Socorro Miranda de; Santos,Jonh Carlo Reis; Deus,Ezequiel da Glória.
Abstract The objective of this study was to evaluate the potential of the pioneer plant species Bellucia grossularioides (L.) Triana (Melastomataceae) to act as a reservoir for parasitoids of fruit flies in the Brazilian Amazon. We collected 48 samples of fruits (total of 4,012 fruits, 43.98 kg) during the months of July, August and September of 2013, in 15 of the 16 municipalities of Amapá State, Brazil. All samples showed infestation by fruit flies, with rates varying from 60.6 to 239.1 puparia/kg of fruit (mean of 106.8 puparia/kg of fruit). The percentage of emergence varied 18.6 to 64.3% (mean of 39.9%). Specimens of Anastrepha coronilli Carrejo & González (Diptera: Tephritidae) were obtained from all samples collected. Specimens of Neosilba...

IS THERE ANY REASON FOR GRAIN STORAGE AND PROCESSING FIRMS NOT TO ADOPT INTEGRATED PEST MANAGEMENT PRACTICES? THE ECONOMICS OF IPM IN STORED GRAIN AgEcon
Adam, Brian D.; Mah, Poh Mun; Phillips, Thomas; Flinn, Paul W.; Anderson, Kim B..
Many grain storage elevator operators have been reluctant to adopt IPM practices. Previous work has found that although IPM reduces pesticide use and associated costs, it requires more management skill and labor, both expensive inputs. So, some IPM practices are more expensive than conventional chemical-based practices, while some are less expensive. However, no studies have measured the costs of grain damage caused from incompletely controlling insects. Applying treatments when they are not needed adds unnecessary, though typically small, costs. However, not applying treatments when they are needed results in large costs due to grain damage discounts. An insect growth model is used to predict numbers of grain-damaging insects in a storage facility so that...

Should Grain Elevator Managers Adopt Integrated Pest Management? AgEcon
Adam, Brian D.; Siaplay, Mounir; Brorsen, B. Wade; Flinn, Paul W..
Insect infestation during storage and processing causes millions of dollars of wheat damage annually in the United States. Insect infestation reduces wheat storing processing profit as well as consumer confidence in wheat food products. Meanwhile, increased concerns about insecticide use have increase interest in Integrated Pest Management (IPM) strategies. This research compares the costs of IPM and chemical-based approaches to insect control to determine why most elevator managers have not adopted IPM practices.

Feed transition in larval rearing of bocudo, Steindachneridion scripta (Pisces, Pimelodidae), using Artemia spp. nauplii and artificial diet Arq. Bras. Med. Vet. Zootec.
Adamante,W.B.; Weingartner,M.; Nuñer,A.P.O..
Feed transition of Steindachneridion scripta larvae was investigated using seven treatments in which the reference diet, Artemia spp. nauplii, was totally substituted for a 56% crude protein artificial diet in two-day intervals. Initially, all treatments were fed with Artemia spp. nauplii and, subsequently, during the transition period, feed was equally composed by Artemia sp. nauplii and artificial diet. Everyday, one of the treatments began the feed transition, which was implemented between the second and the eighth days of culturing. Two treatments were used as control: one exclusively fed Artemia spp. nauplii and another only with artificial diet. Total weight, total length, and survival rate were not influenced by the...

Estimating the Value of Invasive Aquatic Plant Control: A Bioeconomic Analysis of 13 Public Lakes in Florida AgEcon
Adams, Damian C.; Lee, Donna J..
We present a bioeconomic model of three invasive aquatic plants (hydrilla, water hyacinth, and water lettuce) in 13 large Florida lakes, and simulate one-year and steady-state impacts of three control scenarios. We estimate that the steady-state annual net benefit of invasive plant control is $59.95 million. A one-year increase in control yields steady-state gains of $6.55 million per year, and a one-year lapse causes steady-state annual losses of $18.71 million. This model shows that increased control of hydrilla, water hyacinth, and water lettuce is optimal.

Bioeconomic Modeling of the Invasive Aquatic Plants Hydrilla verticillata (hydrilla), Eichhornia crassipes (water hyacinth), and Pistia stratiotes (water lettuce) and their impacts on angler effort on Florida lakes AgEcon
Adams, Damian C.; Lee, Donna J..
The invasive aquatic plants Hydrilla verticillata (hydrilla), Eichhornia crassipes (water hyacinth), and Pistia stratiotes (water lettuce) have the potential to negatively impact recreational use of Florida lakes if consistent, adequate control expenditures are not made. In the mid-1990's, Florida significantly reduced its spending on invasive aquatic plant control measures, which resulted in a significant increase in needed control expenditures in subsequent years. This paper attempts to formalize a relationship between coverage of these invasive aquatic plants and angler effort on Florida lakes using data on 38 lakes over 20 years. Estimated regression...

Optimal investment in prevention and control of a potential invader: the case of zebra mussels in Florida waterways AgEcon
Adams, Damian C.; Lee, Donna J.; Rossi, Frederick J..
The probability of a severe infestation ranges from 2% to 98% depending on investment in monitoring, prevention, and response technology. Given the estimated potential for economic damages, preliminary results indicate that prudent investment in prevention and early response net a present value net return of $10 million over 20 years.

PEACH PRICES IN CALIFORNIA IN THE PRESENCE OF TECHNOLOGICAL CHANGE IN THE AGRICULTURAL PESTICIDE INDUSTRY AgEcon
Adams, Jaime Coakley; MacNair, Douglas J.; Bingham, Matthew F.; Hostetter, Leigh.
The potentially adverse effects of pesticides in wide use are causing concern to grow in the agricultural community. Minimizing the risks to human health and the environment created by agricultural pesticides has become a very important issue. The United States Environmental Protection Agency (EPA) has set a high priority on registering safer pesticides. According to the EPA, more than 1 billion pounds of active pesticide ingredients are used in the United States each year. Americans are exposed to pesticides every day through food consumption, cleaning products, and home and work environments. The agricultural pesticide industry has experienced an influx of changes during the past decade. Two of the primary changes affecting the pesticide industry...

Adan,C.B.D.; Sato,E.H.; Sousa,L.B.; Oliveira,R.S.; Leão,S.C.; Freitas,D..
In order to develop a new experimental animal model of infection with Mycobacterium chelonae in keratomileusis, we conducted a double-blind prospective study on 24 adult male New Zealand rabbits. One eye of each rabbit was submitted to automatic lamellar keratotomy with the automatic corneal shaper under general anesthesia. Eyes were immunosuppressed by a single local injection of methyl prednisolone. Twelve animals were inoculated into the keratomileusis interface with 1 µl of 10(6) heat-inactivated bacteria (heat-inactivated inoculum controls) and 12 with 1 µl of 10(6) live bacteria. Trimethoprim drops (0.1%, w/v) were used as prophylaxis for the surgical procedure every 4 h (50 µl, qid). Animals were examined by 2 observers under a slit lamp on the 1st,...

EFFECTS OF DIFFERENT FEEDING STRATEGIES ON FORAGING ABILITY AND NUTRIENT DIGESTIBILITY OF A SLOW GROWING ORGANIC BROILER GENOTYPE Organic Eprints
ADEBOYE, OLUWAKEMI RACHAEL.
The organic poultry production in Europe is increasing. The use of organic feed has been seen as one of the major constraint especially the protein sources, and efforts have been made to secure the future of this system. Access to outdoor area by organic chicken has been described as a means to partly compensate for their nutritional needs and the knowledge of feed items selected in the outdoor area can ease 100% transition to organic feed. An experiment was conducted to examine the effects of different feeding strategies on the foraging ability and nutrient digestibility of slow growing organic broilers with or without supplement. A total number of Seven hundred and twenty birds (RedBroja and Hubbard genotypes) have access to three different diets (

Optimal Density for Municipal Revenues AgEcon
Adelaja, Adesoji O.; Chaudhuri, Malika.
The distribution of lot sizes and associated improvements affect property values. Hence, zoning affects municipal property tax revenues. If optimal lot size is inconsistent with the targeted zoning density in a community, municipal revenue can be increased through zoning change. This paper theoretically derives the optimal lot size that maximizes tax revenues as a function of the elasticities of improvement value and lot size prices with respect to density, and the elasticities of land and improvement demand with respect to lot size. Empirical hedonic pricing model estimates for a Michigan Community suggest that the optimal lot size for recently sold property is lower than current zoning on existing properties. The possibility that municipal revenue can...

Impact of human schistosomiasis in sub-Saharan Africa BJID
Adenowo,Abiola Fatimah; Oyinloye,Babatunji Emmanuel; Ogunyinka,Bolajoko Idiat; Kappo,Abidemi Paul.
Schistosomiasis, a neglected tropical disease of poverty ranks second among the most widespread parasitic disease in various nations in sub-Saharan Africa. Neglected tropical diseases are causes of about 534,000 deaths annually in sub-Saharan Africa and an estimated 57 million disability-adjusted life-years are lost annually due to the neglected tropical diseases. The neglected tropical diseases exert great health, social and financial burden on economies of households and governments. Schistosomiasis has profound negative effects on child development, outcome of pregnancy, and agricultural productivity, thus a key reason why the "bottom 500 million" inhabitants of sub-Saharan Africa continue to live in poverty. In 2008, 17.5 million people were treated...
