Description Climate change is a major concern for agriculture globally. Dynamic climatic parameters including
increased temperature and carbon dioxide have greatly affected crop production. As a consequence of
climatic uncertainties, new insect pests have emerged, the crop cultivation practices have changed, and
drought and floods have created havoc around the globe. Besides, plant and insecticidal resistance against
insects and diseases has got compromised, the diversity and abundance of arthropods has changed,
geographical ranges of insect pests have extended far beyond their existing limits and new biotypes have
evolved. All these have led to the reduced efficacy of crop protection technologies, huge crop losses,
thereby, food insecurity. Although concerted efforts have been made and simulation models have been
developed to mitigate the climate change effects on plants, still, most simulation models fail to account
for losses due to pests, weeds and diseases. In addition, the monitoring data of insect pests are not
available in most of the developing countries and the software models developed for prediction analysis
are not effective against insect- pests. This review highlights the possible impacts of climate change on
phytophagous insects, chemical ecology, and plant pest interactions leading to food insecurity and the
strategies thereof.
