Florida Scientists Design 3-D Printed Insect Traps | Potato Grower Magazine

Farmers in the SunshineState have seen their share of devastating pests. There’s the invasive Asian citrus psyllid (Diaphorina citri), a vector for bacteria that cause the infamous citrus greening disease, which is tearing through the state’s orange groves, costing Florida an estimated $4.5 billion in lost economic output and more than 8,000 jobs during just a five-year period. And if that weren’t bad enough, the potato/tomato psyllid (Bactericera cockerelli), so named for carrying a disease that ruins those crops and others, has been spotted on trucks transporting goods over Florida’s borders—an infestation waiting to happen.

To halt such an infestation, hundreds of state inspectors in Florida run trap lines to see what insects are being introduced into the state. The most common psyllid monitoring efforts use sticky traps made with a glue called “tanglefoot.” Sticky traps require frequent trips by inspectors to remove insects, and often the specimens are too damaged to do any meaningful molecular or genetic work.

But researchers are now employing 3-D printing technology to build far more complicated contraptions.

P.E.I. potato-tampering more widespread than first disclosed

P.E.I. potato-tampering more widespread than first disclosed

RCMP admit they didn t immediately release information about their investigation into the Prince Edward Island potato-tampering case, saying there was no perceived threat to the public.

According to the RCMP, an investigation began on Oct. 3, when Mounties were called in after sewing needles were found in some of the french fries at a Cavendish Farms processing plant in New Annan, P.E.I.

However, a statement warning the public about the issue was not released until Oct. 6, after it was reported that a tampered potato made its way into a consumer s home.

RCMP Sgt. Leanne Butler said Thursday that the public now knows about every case. As soon as we got the reports the next day that there was a potato in the public, table potatoes, that s when we did our news release to make sure the public knew right away, she told CTV Atlantic. All of what we are aware of has been released at this point.

Treat disease in shrimp aquaculture congress - NewsHub

Syndrome Early Mortality Shrimp (EMS), will be among the topics covered during the XVI Congress of aquaculture, Acuaexpo 2014 to be held in Guayaquil from 20 to 23 October.

The first cases of the disease caused by the bacterium Vibrio parahaemolyticus, were reported in 2007 and has primarily targeted to Asian countries like China and Vietnam, and America, to Mexico, where the survival of the resource is only 30%, what worries the local aquaculture sector.

Many fish in fish farms die thanks to vibrio bacteria | The Real Singapore

Fish farmers are losing large amounts of their stock again, this time thanks to an increase in the vibrio bacteria.

The Vibrio bacteria is naturally found in tropical marine environments but its abundance has increased dramatically thanks to warmer weather and rising sea surface temperatures.

The micro-organisms have been growing and releasing toxins which kill the fish. The remaining fish are also affected with the bacteria which can give humans diarrhoea, vomiting and fever if infected.

Humans can be infected by the bacteria if they expose open wounds to sea water or eat undercooked or raw fish which contain the bacteria.

Fish farmers have also been hit hard with 60 tonnes of fish dying thanks to the vibrio bacteria.

Mr Phillip Lim, the chairman of the Singapore Marine Aquaculture Cooperative which owns 2 farms in Lim Chu Kang lost most of their fish stock and they are left with only 200 to 300 fish after an initial stock of over 8,000.

The Agrifood and Veterinary Authority had tested samples of the dead fish as most of the farmers don’t have the equipment to do such testing.

Biocontrol for alfalfa pest may be useful to NY apple growers

A biocontrol treatment developed to help Northern New York alfalfa growers is now showing early promise of proving useful to New York apple growers.

Early field trials in four NY orchard plantings have shown a reduction of 70 to 97 percent, compared with untreated plantings, in the populations of plum curculio, a key pest of eastern U.S. apple crops.

With long-term funding from the farmer-driven Northern New York Agricultural Development Program, Cornell University entomologist Elson Shields developed a biocontrol protocol for using a combination of native New York nematodes to reduce alfalfa snout beetle populations in NNY alfalfa crops.

Shields and Cornell colleague Art Agnello are now applying nematodes to control plum curculio in organic-production apple plantings.

Plum curculio is especially troublesome for organic growers whose main defence has been multiple applications of kaolin clay to act as a physical barrier to attack by the insect pest. Organic treatment programs for managing plum curculio can easily range from $150 to $450 per acre per year and fruit damage often remains at five to 20 percent.

Oyster season opens next week

BRUNSWICK — Georgia waters will reopen to commercial and recreational oyster harvest effective 7 a.m. Wednesday, Oct. 1.

Following an announcement by state Department of Natural Resources Commissioner Mark Williams in May, oyster harvest in state waters was prohibited from June 1 through midnight Sept. 30 to meet the requirements of Georgia’s Vibrio parahaemolyticus (Vp) control plan. Vp is naturally occurring bacteria found in filter-feeding shellfish at higher concentrations during the months of the year when water temperatures are warm.

“The four-month closure ensures that Georgia meets requirements of the National Shellfish Sanitation Program to protect public health during the summer months, when Vp levels are typically the highest of the year,” said Dominic Guadagnoli, shellfish fishery manager for the Coastal Resources Division. “As water temperatures begin to drop in October, the Vp levels will decline and the risk lessens. Traditionally, most consumers purchase live oysters during the cooler months, so commercial shellfish harvesters are fully supportive of this seasonal closure.”

The Lakes Region ISA post crisis, challenges for territorial development in WordPress.com

We have already finished Calbuco field and return to Santiago to think about it and remember that cold and smell. My initial issue was to investigate the territorial implications of the salmon industry in the territory after ISA Calbuco, being interested in the different expressions that might have had on the population, rural-urban, gender relations, lifestyles, etc. But gradually I began to understand that the real impact it had artisanal fishermen, not directly and intentionally companies to them, but had to absorb the externalities of a competitive industry with a growth rate very fast for zone. These externalities are expressed in everyday life, in everyday pollution that appears on the beaches, in reducing the size of the shellfish, and misinformation regarding the actual consequences of the abuse of pesticides and larvicides thrown into the Chilean Sea.

Currently about 42% of salmon farms are located in the region of Los Lagos, and last year 1654 these actively operated in region (SERNAPESCA, 2014). The s

Frozen shrimp now accounts for 78% of the total seafood consignments from India - Economic Times

KOCHI: Global shortage of farmed shrimp continues to boost India's seafood export prospects. After crossing the Rs30,000-crore mark last year, the shipments have shown nearly 30% rise till the end of July with vannamei shrimp bringing in a significant part of the revenue.

Frozen shrimp now accounts for 78% of the total seafood consignments from India, up from 71% in the same period last year. Another notable feature is that exports to the European Union and Middle East have increased during four months.

Seafood exports from India totalled 2,41,600 tonne valued at Rs9,345 crore during the period April-July 2014. Though there is only a marginal increase in quantity, the value is up by 29%, indicating good prices for Indian shrimps.

"Middle East countries have been buying lot of Indian seafood, particularly Egypt, Saudi Arabia and UAE. There has been failure of white shrimp crop in Saudi Arabia," said Anwar Hashim, managing director of Abad Fisheries, a leading exporter. The prices of Indian shrimp, he said, increased from Rs500 to Rs650 per kg , though it has come down in the recent weeks.

Concern at proposed Aran fish farm plan – Irish Examiner

The state agency in charge of the country’s rivers has called on the Department of Agriculture to consider a study which concluded fish farming has a “general negative effect” on sea trout stocks, when deciding to grant permission to a planned 1,000-acre fish farm off the Aran Islands.

The Norwegian research concluded that fish farming generates increased numbers of sea lice, a naturally-occurring parasite that feed off salmon and sea trout, and this increase can lead to potentially 12-44% fewer salmon spawning in areas where there is intensive salmon farming. It also said intensive fish farming can lead to falling sea trout stocks and reduced growth in surviving sea trout stocks….
