Pheromone-baited traps have been widely used for the monitoring of cotton bollworm, Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae), in order to time any control measures during growing season. Different techniques may provide differential results regarding adult captures. However, studies on comparative evaluation performance different trap types captures H. are limited. To close this g...

Knowing how climate change affects the population dynamics of insect pests is critical for the future of integrated pest management. Rising winter temperatures from global warming can drive increases in outbreaks of some agricultural pests. In contrast, here we propose an alternative hypothesis that both extremely cold and warm winters can mismatch the timing between the eclosion of overwinteri...

China is the largest cotton-producer in the World with about 4.5 million tons of lint produced annually, which accounts for over 20% of the World’s total production (Xia et al. 2001). Damage from pests is one of the major limiting factors for cotton production in China, among which cotton bollworm (Helicoverpa armigera Hübner) is a key one (Fang et al. 1992). In the early 1990s, due to the dram...
