Overview

Observational study reveals silver-gray plastic film reduces thrips in cowpea, highlighting a potential alternative to pesticides.

Key Points

  • Silver-gray plastic film significantly reduces the number of megalurothrips usitatus in cowpea, particularly in the early growth stages.
  • Repellency rates were over 90% for male and 85% for female thrips when using silver-gray plastic film.
  • Observational analysis across various growth stages shows fewer thrips in areas with silver-gray film compared to controls.
  • Significant differences in thrips numbers are mostly noted before flowering, with diminished effects during peak flowering.
