Drosophila suzukii, alarm cherries Etna - Italiafruit News

They were the first reported outbreaks spread of Midge soft fruit fly (Drosophila suzukii) in the district of Mascali (Catania) on cherry tree where it causes serious damage to the fruit. This small Diptera has been reported in Italy in 2009 on raspberries and other small fruits and attacks many other species of fruit with fruit pulp soft and thin epidermis as cherry, apricot, grape, etc.

Like all midges belonging to the genus Drosophila is attracted by sugary substances but in this case the female is provided with a serrated ovipositor able to lacerate the skin of the fruit on the plant and lay their eggs in the pulp. The fruit damaged meets later in the phenomena of decay.

This insect performs up to 13 generations and its annual rate of diffusion together with damage to the fruits in the ripening stage make it particularly insidious.

The event, held in Puerto Varas on Thursday October 23, began with the presentation "Intracellular bacteria, challenges in controlling the disease" by the investigating Ph.D. Eva Jakob, who explained that live vaccines are a good strategy against intracellular pathogens, adding that these antigens should be used as support, not as the only measure in the control of diseases.

He also explained that the performance of these vaccines is affected by high infective pressure, pre-existing infection prior to vaccination, as well as due to poor sanitary conditions and stressful episodes.

Regarding the evaluation of the efficacy of these vaccines in the field, the research highlighted the need for well-designed studies and controlled field with sufficient statistical power to be significant.

Another case of Psa disease found in New Zealand

Another case of Psa disease found in New Zealand

Another Gisborne kiwifruit orchard has had a test result come back positive for Psa-V taking the number of infected sites in the Gisborne-Nuhaka district now to 15.

There were two cases identified in a vineyard in the Hexton area back in September involving only a few infected plants, which were removed.

The latest case was identified last week as a result of proactive monitoring, says Kiwifruit Vine Health spokeswoman Lara Harrison.

It was found in an orchard in the Patutahi area. It involved just one vine that had leaf-spotting symptoms and treatment measures have been taken.

The disease is reasonably well contained in the Gisborne area compared to other regions, Ms Harrison says.

There are only 15 reported cases out of 66 kiwifruit orchards in the district.

However a Psa-V find at any time is a reminder that growers must remain vigilant. Keep monitoring is our advice to growers in the district.

A round of mandatory monitoring is due to start next month.

 

Thai court dismisses defamation case against UK activist Andy Hall

Thai court dismisses defamation case against UK activist Andy Hall

A Thai court has dismissed a criminal defamation case against a British labour activist who criticised conditions in the food industry.

The court said the investigation into the case did not meet certain legal requirements.

Last year, Mr Hall authored a report for Finnwatch, a Finland-based watchdog, alleging poor labour conditions in seafood and pineapple export companies in Thailand. The allegations include wages below the legal minimum, long working hours at factories and illegally confiscating passports.

Natural Fruit, a Thai pineapple company, which brought the charges, was one of the companies named and denies the findings of the report.

The defamation charges relate to an interview Mr Hall gave to the Al-Jazeera network on the allegations in the report while in Myanmar (formerly known as Burma).

Mr Hall, an activist from Spalding, Lincolnshire, authored a report exposing labour abuses in Thailand

SAG establishes control compulsory for blueberries Lobesia botrana MRI

According to information provided to SimFRUIT by Grisel Monk, Executive Director of the National Program Lobesia botrana Agricultural and Livestock Service, SAG, from next week all blueberry growers with orchards in control areas shall place the Metropolitan Region implement the Mandatory Control Program established by the authority, together with the private sector to prevent the spread of the grapevine moth.

The measure was established through the SAG Resolution N ° 2991/2014 of October 23, supplementing Resolution No. 2508/2014 establishing mandatory control moth cluster Vid (Lobesia botrana) for blueberries ( Vaccinium corymbosum) in regulated areas of the metropolitan region.

Obligatory control blueberries was determined from Region VI to the Biobío Region, now being included in the Metropolitan Region, given the detection of an immature state in blueberry plants Lobesia noncommercial, an urban locality in the municipality of San Bernardo, and under normal surveillance activities SAG.

To wilt or not to wilt: New process explains why tomatoes are susceptible to a disease-causing fungus

Posted at October 28, 2014 | By : admin | Categories : Company News | Comments Off

Plant breeders have long identified and cultivated disease-resistant varieties. A research team at the University of California, Riverside has now revealed a new molecular mechanism for resistance and susceptibility to a common fungus that causes wilt in susceptible tomato plants.

Shown are tomato plant varieties that are sensitive (Moneymaker; left panel) or resistant (Motelle; right panel) to the fungal pathogen Fusarium oxysporum. Each panel shows a water-treated control plant on the left and two F. oxysporum-treated plants on the right. Exposure of Moneymaker to F. oxysporum results in severe wilting, while Motelle is resistant.

SERNAPESCA confirms ISA virus presence in farming centre

The National Marine Fisheries Service (SERNAPESCA) has confirmed the presence of the virus of the infectious salmon anemia (ISA) in the farming centre Ballena 4, belonging to the company Salmones Cupquelan SA, located in the south of the Aysen Region.

The authority notified the company on this situation after having obtained positive results on the samples taken by the service and the company.

"In accordance with the provisions of the Specific Health Surveillance and Infectious Salmon Anemia Control Programme, the Service has notified the centre as 'Confirmed Other HPR," SERNAPESCA said in a statement.

In addition, it also reported that it verified the absence of clinical signs and mortality associated with the disease.

"The company began harvesting the positive cages last weekend, under strict biosecurity measures," added SERNAPESCA.

The New Delhi virus was detected in several areas of the Guadalquivir Valley

The 2014-2015 horticultural season is beginning about three weeks later than expected as farmers are afraid and uncertain about the New Delhi virus, which affected production last year, when it was detected in the province of Almeria and caused damage mainly to the zucchini production. Currently, the news in Almeria is that this virus has also reached the Guadalquivir Valley, as was noted by elhocino-adra.blogspot.com, a well-known blog about agriculture created by entomology expert Antonio M. Aguilera.

The virus (ToLCNDV) had already been detected in a few plants in September last year in this area. However, Aguilera recently found new occurrences of the virus, this time in black melon plants, in a small greenhouse of Cordoba. "The foliar symptoms could be attributed to a thousand and one reasons but there is no doubt it is the New Delhi virus as the fruit also has longitudinal cracking," he stated in his blog. "It seems this time it is a more serious infection, with many affected plants, which may impede continuing the crops until the end," he says.

Authorities confirm ISA in Cooke Chile farm - Undercurrent News

Chile’s aquaculture management body, Sernapesca, confirmed on Friday Oct. 24 the presence of Infectious salmon anemia (ISA) in a center of Salmones Cupquelan, part of Cooke Aquaculture.

After positive results from sampling conducted by the body and the Cupquelan,the company started the harvest of affected cages at Ballena IV center, in southern Aysen, during this weekend, under strict bio-security measures.

The site has 620,000 fish, approximately, Cupquelan’s general manager Andres Fuentes told Undercurrent News, following the notice of the suspected case last week.

Cupquelan had started proceedings to immediately harvest the fish, while putting in place sanitary measures required to prevent the spread of any disease.

“We are presenting today a plan to Sernapesca to harvest the full site as fast as possible,” Fuentes told Undercurrent.

Containment measures are facilitated by the fact that Cupquelan owns all the licenses in the neighborhood where the fish is being tested.

Disease still plaguing Thai shrimp - Bangkok Post

Shrimp exports are not expected to recover until next year's second quarter, as Thailand has yet to eliminate early mortality syndrome (EMS) from its shrimp farms.

"Overall shrimp exports remain in bad shape, with the conditions expected to be prolonged until next year," said Poj Aramwattananont, president of the Thai Frozen Foods Association.

"For this year, we expect the country's total production to reach only 200,000 tonnes, with export volume expected to fall by 25% from last year."

EMS first hit a shrimp farm in China in 2009, then moved through Vietnam before spreading to Thailand in mid-2012.

The outbreak has severely damaged the Thai shrimp industry and exports of related products.

Before the disease hit Asian farms, Thailand produced 500,000 to 600,000 tonnes of shrimp annually.

But that figure fell by 42% last year to 270,000 tonnes, while shrimp exports fell by 34% to 187,000 tonnes worth 60 billion baht.

Mr Poj said shrimp export value this year was expected to fall by 12% from last year.
