Description
Haihang Zhou and co-authors release a predatory lacewing against cowpea thrips in this 2026 paper. Thrips outbreaks have hit tropical crops hard. The green lacewing Chrysopa formosa eats many pests, and two thrips species plague South China cowpeas. Lab tests measured how the predator's appetite scales with prey density.
A top-stage larva could theoretically eat over a thousand young thrips in a day. In field cages, young larvae cleared more than seven-tenths of a mixed thrips population within two weeks. Warmth sped predation up to thirty-five degrees, though growth slowed above twenty-five. Egg hatching held steady in the heat. The authors back the lacewing as a field-ready control.
