Call for help from plants before imminent pest attacks
The deposition of eggs by insect pests has been shown to trigger the release of chemical signals from plants, attracting species to assist the plant in resisting attack. This is a valuable tool in the plant’s defences as it is initiated at the first sign of the pest, even before feeding has begun. The research…
Artificial Intelligence employed to protect crops against the oriental fruit fly.
A new system has been developed in Taiwan which uses Artificial Intelligence (AI) in the monitoring of the oriental fruit fly (Bactrocera dorsalis). The system uses infrared beams to detect the number of flies present in the area, in order to predict impending outbreaks. It is hoped that this system will reduce the need for…

US drought could spark a global food crisis
The US is currently facing its most severe drought of the past 50 years, raising questions about the implications for global food security.

Solution to devastating weed draws closer for sub Saharan Africa
Striga, commonly known as witchweed, is a group of parasitic weeds found in over a third of cereal crops in sub Saharan Africa (SSA). Crops typically yield at least 40% less when they are parasitised by Striga, causing an estimated US$ 7 billion loss and reducing the food security of millions.
