Red swamp crayfish (Procambarus clarkii), often known as the Louisiana crawfish are staple part of Cajun cuisine. However, new research published in Conservation Biology has found that the highly invasive crayfish allows mosquitoes to thrive in waterways, therefore making it more likely to increase the risk of mosquito-borne diseases.  Continue reading

The use of DNA to detect a stinkbug invasion proposes a revolutionary advancement in agricultural pest surveillance following the success recorded on a piloted experiment conducted on farms in the USA. These interlopers attack all manner of produce, ranging from fruits to leafy vegetables.  However, the adoption of DNA techniques in detecting its early invasion may help to bring its assault to a halt, as opposed to the use of pheromone traps which may only be effective after the pest’s population are pronounced.
