Background: Between 1955 and 2011 there were marked fluctuations in suicide rates in Sri Lanka; incidence increased six-fold between 1955 and the 1980s, and halved in the early 21st century. Changes in access to highly toxic pesticides are thought to have influenced this pattern. This study inves...

Whiteflies are a key pest of crops in open-field production throughout the tropics andsubtropics. This is due in large part to the long and diverse list of devastating plantviruses transmitted by these vectors. Open-field production provides many challengesto manage these viruses and in many case...
