Scientists gear up to battle invasive species

Posted on أربعاء, 24 أغسطس 2016, 08:34

A research programme to tackle invasive species that kill plants and sicken animals is getting under way at the United Kingdom’s Centre for Agriculture and Bioscience International (CABI). The programme, worth US$50 million, aims to find scientific solution that help farmers to either defeat or adapt to the presence of invasive species. The goal is to tackle the devastating economic impact of such species, estimated to be around $183 billion in lost crops and revenue in Sub-Saharan Africa, South Asia and South-East Asia every year.

Most nations lack ability to deal with invasive species

Posted on ثلاثاء, 23 أغسطس 2016, 15:07

Most countries in the world have little capacity to deal effectively with invasive species, a study suggests. The spread of non-native species threatens livelihoods and biodiversity, but the issue is worsened by global trade, travel and climate change. They show that one-sixth of the world's land surface is vulnerable to invasion. In what the authors say is the first evaluation of its kind, the paper assesses individual nations' abilities to manage existing invasive species and respond to new ones.

New York City Battles on Against Dutch Elm Disease

Posted on ثلاثاء, 26 يوليو 2016, 09:36

Like elm trees across the globe, the elms in Central Park are stricken with a ruthless beetle–fungus alliance known as Dutch elm disease. In the early 1980s, the park was losing more than 100 elms—American and other species—each year. Today, thanks to diligent monitoring and eradication by the Central Park Conservancy, the death rate is much lower—sometimes in the single digits—although bad years can still claim as many as 35 trees. The fight goes on .....

'Biblical' moth influx threatens to devastate crops

Posted on ثلاثاء, 14 يونيو 2016, 17:27

Scientists have learned that cabbage and cauliflower crops could potentially be "devastated" by a species of moth arriving from continental Europe. BBC News understands that tens of millions of diamondback moths are thought to have come to the UK in the past week. Researchers describe the species as a "super pest" because it is thought to be resistant to several insecticides. An alert has been issued by researchers at the Rothamsted Research in Harpenden in Hertfordshire.

Experimental Trap Disrupts Citrus Pest’s Love Life - controlling Asian citrus psyllids.

Posted on إثنين, 06 يونيو 2016, 15:54

An acoustic trap developed by U.S. Department of Agriculture (USDA) scientists may offer an environmentally friendly way to control Asian citrus psyllids. These pests transmit Huanglongbing, a devastating citrus disease also known as “citrus greening.” Infected citrus trees cannot be cured and often die within several years. Until such time, they may bear green, misshapen fruit with acidic-tasting juice, making the fruit unmarketable. Concern over the cost and long-term environmental impact of using insecticides to control psyllid populations in citrus-growing states like Florida has prompted an intensive search for alternative measures, notes Richard Mankin, an entomologist with USDA’s ...

US releases millions of wasps to fight emerald ash borer

Posted on أربعاء, 25 مايو 2016, 14:24

Parasite from China attacks eggs and larvae of Asian insect pest (emerald ash borer) that has wiped out tens of millions of trees in north America. Millions of tiny wasps that are natural parasites for the emerald ash borer have been released into wooded areas in 24 states of the US to try and peg back the tree-killing insect’s advances. The US Department of Agriculture has researched and approved for release four species of parasitic wasps that naturally target the larval and egg stages of the ash borer, which has killed an estimated 38m ash trees in urban and ...
