University of Illinois entomology professor May Berenbaum discusses lessons learned from decades of efforts to eradicate the New World screwworm, a devastating insect pest. In a 2016 Science journal essay, she examined the successful but temporary eradication of this pest in many regions worldwide. The case demonstrates the critical importance of basic science in insect biology, particularly when confronting crisis situations involving destructive pest species.


Understanding the screwworm eradication efforts provides valuable insights for managing future pest outbreaks and demonstrates how fundamental research in entomology can inform effective pest control strategies. The temporary nature of the eradication success highlights ongoing challenges in maintaining pest-free status and the need for continued vigilance and scientific investment.

The value of basic science in insect biology is no more evident than when a crisis arises involving a devastating insect pest like the New World screwworm, says University of Illinois entomology professor May Berenbaum. In a 2016 essay in the journal Science, Berenbaum wrote about the successful—if temporary—eradication of the pest in many parts of the world. Here she answers common questions about the screwworm’s return.
