While we have been filling our homes with traditional Christmas trees, the long-horn beetle has instead decided to go for a more up-market décor. Boswellia trees, which produce the resin used to make frankincense, have recently suffered from a worrying decline in numbers, with experts predicting that we have limited years left to take action to save them. Part of this has been attributed to long-horn beetle larvae setting up home inside them, and eventually leading to the death of the individual.

The Cooperative Research Centre for National Plant Biosecurity (CRCNPB) in Australia is developing a new way to share information on crop pests and diseases. In addition to providing diagnostic tools in the form of a database on plant pests similar to Plantwise’s Knowledge Bank, they have created an online remote microscope network, which “allows species experts to view and identify specimens in real time”. The network already extends to most Australian states, New Zealand, Indonesia and other parts of south-east Asia. The simplicity of the scheme means that many other countries could soon be involved too.

It was love at first sight for many pink bollworms this year, but as their eyes met across the cotton field all was not as it seemed…
Oxitec (a company based not far from the Plantwise Knowledge Bank team), have managed to genetically engineer a strain of pink bollworm (Pectinophora gossypiella) which greatly advances the already used sterile insect technique (SIT). The new strain (affectionately known as Pink Bollworm OX3402) has been genetically engineered to include bisex RIDL technology, which means that they have a RIDL gene that effectively makes them sterile (offspring cannot survive without additional dietary supplements). OX3402 also has Oxitec’s heritable fluorescent marker technology (DsRed), which allows populations of released strains to be monitored more accurately.
Scientists in the UK and Uganda are developing a genetically modified (GM) variety of banana that is resistant to nematode worms, which account for a high percentage of banana crop losses in Africa. It is estimated that the losses of crops due to nematodes amounts to $125 billion a year. Currently, nematodes are controlled using pesticides that can be toxic to humans and other organisms. The project, run by the Africa College at the University of Leeds and funded by BBSRC and DfID, has provided training to African-based scientists and aims to conduct trials of the banana plants in several African countries.
