诱虫灯在现代农业的害虫预测预报和防治工作中得到广泛的应用。草地贪夜蛾于2018年底经云南迁飞入侵中国，严重威胁我国农作物的安全生产。为明确诱虫灯对草地贪夜蛾成虫的诱集效率，我们首先通过转录组测序确定其视蛋白基因的种类和数量。聚类分析表明，与其它夜蛾科昆虫类似，草地贪夜蛾表达4个视蛋白基因。但是草地贪夜蛾视蛋白基因的表达量显著低于棉铃虫中相对应的基因。趋光行为研究表明，棉铃虫和草地贪夜蛾成虫均具有显著正趋光性，其中草地贪夜蛾雌、雄成虫飞向光源的速度均显著高于棉铃虫，这可能是由于草地贪夜蛾飞行速度高于棉铃虫所致。然而，诱虫灯结果表明草地贪夜蛾的上灯率显著低于棉铃虫，这与视蛋白基因在两种昆虫中的表达水平一致。综上所述，本研究表明草地贪夜蛾成虫具有趋光性，诱虫灯可用于该虫的预测预报及防治工作，但诱集效率低于棉铃虫。

With consecutive occurrences of drought disasters in China in recent years, it is important to estimate their potential impacts on regional crop production. In this study, we detect the impacts of drought on wheat and maize yield and their changes at a 0.5°×0.5° grid scale in the wheat-maize rotation planting area in the North China Plain under the A1B climate change scenario using the Decision Support System for Agrotechnology Transfer (DSSAT) model and the outputs of the regional climate modeling system - Providing Regional Climates for Impacts Studies (PRECIS). Self-calibrating palmer drought severity index was used as drought recognition indicator. Two time slices used for the study were the baseline (1961-1990) and 40 years of 2011-2050. The results indicate that the potential planting region for double crop system of wheat-maize would expend northward. The statistic conclusions of crop simulations varied considerably between wheat and maize. In disaster-affected seasons, wheat yield would increase in the future compared with baseline yields, whereas in opposite for maize yield. Potential crop yield reductions caused by drought would be lower for wheat and higher for maize, with a similar trend found for the ratio of potential crop yield reductions for both crops. It appears that the negative impact of drought on maize was larger than that on wheat under climate change A1B scenario.
