The value of research on plant resistance to insects

Written by Alison Doody on . Posted in Videos.

Crop pest outbreaks are a serious threat to food security worldwide. Swarms of locusts continue to form in the Horn of Africa, threatening food security and farmer livelihoods ahead of a new cropping season. The devastating fall armyworm continues cause extensive damage in Africa and South Asia.

With almost 40% of food crops lost annually due to pests and diseases, plants resistance to insects is more important than ever. Last month, a group of wheat breeders and entomologists came together for the 24th Biannual International Plant Resistance to Insects (IPRI) Workshop, held at the International Maize and Wheat Improvement Center (CIMMYT) global headquarters outside Mexico City.

Watch Mike Smith, entomologist and distinguished professor emeritus at Kansas State University explain the importance of working with economists to document the value of plant insect resistance research, and why communication is crucial for raising awareness of the threat of crop pests and insect resistance solutions.

Wheat curl mites: What are they and how can we fight them?

The wheat curl mite, a pesky wheat pest which can cause up to 100% yield losses, is a significant threat to wheat crops worldwide. The pest has been confirmed in Asia, Australia, Europe, North America and parts of South America. Almost invisible to the naked eye, the microscopic pest is one of the most difficult pests to manage in wheat due to its ability to evade insecticides.

We caught up with Punya Nachappa, an assistant professor at Colorado State University, at this year’s International Plant Resistance to Insects (IPRI) Workshop to discuss wheat curl mites and how to fight them. She explains how the mite cleverly avoids insecticides, how climate change is leading to increasing populations and why breeding for host plant resistance is the main defense against outbreaks.

ICARDA’s Mustapha El-Bouhssini explains how crop pests are moving in a warming world

Insect resistance in plants is needed now more than ever. The UN, which has named 2020 as the International Year of Plant Health, estimates that almost 40% of food crops are lost annually due to plant pests and diseases.

Earlier this month, a group of wheat breeders and entomologists came together for the 24th Biannual International Plant Resistance to Insects (IPRI) Workshop, held at the International Maize and Wheat Improvement Center (CIMMYT).

We caught up with Mustapha El-Bouhssini, principal scientist at the International Center for Agricultural Research in the Dry Areas (ICARDA) to discuss insect pests and climate change. He explains how pests such as the Hessian fly — a destructive wheat pest which resembles a mosquito — and the chickpea pod borer are extending their geographical ranges in response to rising temperatures.
