Recent research highlights why the green peach aphid (Myzus persicae) is one of the most successful crop pests. These findings will help further the development of effective management and control measures which will ultimately reduce worldwide crop losses.
New research announced today by scientists at CABI confirms that a recently introduced crop-destroying armyworm caterpillar is now spreading rapidly across Mainland Africa and could spread to tropical Asia and the Mediterranean in the next few years, becoming a major threat to agricultural trade worldwide.

Dubbed an E-Nose, the equipment has been developed by engineers and scientists to detect crop pathogens by smell weeks before any infection becomes outwardly apparent or evident on any visual basis.
“It’s an amazing tool for early detection,” commented Kit Franklin, a lecturer of agricultural engineering at Harper Adams University.
Australian researchers have developed a new nanotechnology pesticide spray called BioClay which has shown success in recent trials.
Developed by the Queensland Alliance for Agriculture and Food Innovation (QAAFI) and the Australian Institute for Bioengineering and Nanotechnology (AIBN), BioClay contains double stranded RNA which can be sprayed onto a crop. When the RNA contacts the plant, the plant believes it is being attacked by a virus and protects itself.

Zambia must intensify its fight against an outbreak of armyworms that’s wiping out fields of the staple corn crop, posing a threat to the southern African nation’s food security, Vice President Inonge Wina said.
“They are posing a big threat to food security in the country,” she said in remarks broadcast Monday on Hot FM radio in Lusaka, the capital. “They have come with such a force of mass destruction that has to be faced head on. We need to put more effort into eradicating the worms.”

Climate change has emerged as one of the most important environmental, social and economic issues today – especially for South Asia, which is highly impacted by these changes. In light of this, an international conference on Biodiversity, Climate Change Assessment and Impacts on Livelihood (ICBCL) was convened in Kathmandu from 10-12 January 2017. The conference was opened by Bidhya Devi Bhandari, the President of Nepal, and saw participation from eminent scientists, policy makers and development workers across the agriculture sector in South Asia.

A severe infestation of the papaya mealybug (Paracoccus marginatus) nearly wiped out papaya orchards in Pakistan before the largely farmed country decided to replace conventional chemical pesticides that were ineffective with natural predators that proved to be successful.
The system was developed by agro-biotechnologists and entomologists at the Pakistani chapter of the UK-based Centre for Agriculture and Bioscience International (CABI) who introduced the use of Acerophagus papayae, a parasitoid (insects whose larvae parasite upon and eventually kill the host), to effectively control the mealybug infestation.
