Quick Summary

Beijing is dealing with an infestation of invasive moths whose caterpillars have severely damaged trees in the city and surrounding areas over the summer. The caterpillars spin greyish-white webs as they feed on plant foliage, threatening hundreds of local plant species. To combat this issue, Beijing has employed both parasitic wasps to control the moth population biologically and organized caterpillar-catching contests as part of their broader strategy. Chen Min, a professor at Beijing Forestry University, notes that the current generation of larvae poses an increased risk for spread, complicating eradication efforts.

Story summary

Beijing is facing an infestation of invasive white moth caterpillars that have blanketed trees in the Chinese capital and surrounding areas during summer 2023. These fuzzy larval insects pose a threat to hundreds of species of plants, as they consume foliage and spin greyish-white webs on trees. The larvae are the immature stage of Hyphantria cunea, commonly known as fall webworm moths.

To combat this issue, authorities at Beijing Forestry University have recommended using parasitic wasps to control the caterpillar population naturally, while also organizing caterpillar-catching contests to engage public participation in pest management. Professor Chen Min from Beijing Forestry University noted that the current generation of larvae poses an unusually high risk for spreading compared to previous years, complicating traditional control methods.
