As 2019 draws to a close, we have crunched the numbers and pulled together the year’s most read articles. Plus some firm favourites.
Fall armyworm continues to be a popular topic for our readers and this year, blogs on biocontrol efforts to control the invasive caterpillar make the top 20. CABI’s Pest Risk Analysis tool also grabbed readers’ attention and appears twice in the chart.
Guest authors have also been very popular this year covering species like coypu and slugs, and dogs that sniff out Japanese Knotweed.
