Targeting cell death processes for insect pest control: a promising but still underexploited strategy.
Tettamanti G, Casartelli M, Mohamed A, Toprak U, Bruno D
Summary
PubMedWhy it matters This matters because new insect pest control strategies targeting insects' own biology could mean fewer broad-spectrum pesticides sprayed on the vegetables in your garden and the crops that produce your food.
Every insect has built-in processes that tell certain cells when to die — this is normal and necessary for them to grow and stay healthy. Researchers are now looking at ways to trigger or disrupt these 'cell death' programs in pest insects using natural compounds, lab-engineered molecules, or gene-editing tools. The goal is to harm only the pest insects we want to control, leaving beneficial bugs like bees and butterflies unharmed.

Scientists are exploring ways to kill harmful insects by targeting the natural cell death processes already built into their bodies. By triggering or hijacking these self-destruct mechanisms, researchers hope to develop more precise pest control tools that are less harmful to other species.
Key Findings
Two natural cell death pathways — apoptosis (targeted cell removal) and autophagy (cellular self-recycling) — are identified as key vulnerabilities that can be exploited to kill insect pests.
Two broad strategies are proposed: using chemical compounds to trigger cell death in critical insect tissues, and using genetic tools like RNAi or CRISPR/Cas9 to disrupt the signaling pathways that regulate these processes.
Current approaches show promise for controlling both crop pests and disease-carrying insects (such as mosquitoes), but researchers caution that specificity, effectiveness, and environmental safety still need significant improvement before real-world application.
Abstract Preview
Cell death-related processes are fundamental to insect physiology, playing essential roles in development, immune response, and metamorphosis, thereby maintaining tissue and organism's homeostasis....
