Can tropical insects stand the heat? A case study with the brown planthopper Nilaparvata lugens (Stål).

The brown planthopper Nilaparvata lugens (Stål) is the most serious pest of rice across the world, especially in tropical climates. N. lugens nymphs and adults were exposed to high temperatures to determine their critical thermal maximum (CT(max)), heat coma temperature (HCT) and upper lethal temper...
