Summary

Sap beetles vector harmful fungi to maize and are resistant to mycotoxins. Integrated pest management strategies are being developed for control, including biological agents and resistant maize varieties.

Area of Science:

  • Agricultural Entomology
  • Plant Pathology
  • Pest Management

Background:

  • Sap beetles (Coleoptera: Nitidulidae) are significant vectors of mycotoxigenic fungi like Aspergillus and Fusarium in maize.
  • These beetles are attracted to fungal and maize volatiles and exhibit higher mycotoxin resistance than maize ear-infesting caterpillars.

Purpose of the Study:

  • To explore integrated control strategies for sap beetles in maize.
  • To identify methods for reducing mycotoxin contamination vectored by sap beetles.

Main Methods:

  • Developing integrated control programs including pheromone-based trapping and host co-attractants.
  • Investigating pathogenic nematodes and fungi for biological control.
  • Identifying maize varieties with cross-resistance to fungi and insects.
  • Formulating selective insecticides and testing autoinoculative devices for biocontrol agent delivery.

Main Results:

  • Sap beetles readily invade damaged or poorly covered maize ears.
  • The integrated control program aims for selective pest reduction while preserving beneficial insects.
  • Autoinoculative devices show potential for using sap beetles to deliver biocontrol agents.

Conclusions:

  • Integrated pest management offers a promising approach to control sap beetles and mitigate mycotoxin risks in maize.
  • Further research into resistant maize varieties and biological control agents is crucial for sustainable management.
