[A preliminary study on benthyloid wasp control for chrysanthemum stem borer]
1Institute of Medicinal Plant Development, Chinese Academy of Medical Sciences, Beijing.
Summary
The Benthyloid wasp effectively parasitizes the Chrysanthemum stem borer, showing high success rates in both laboratory and field conditions. Releasing two wasps per host optimizes parasitic efficiency for pest control.
Area of Science:
- Entomology
- Biological Pest Control
Context:
- Chrysanthemum stem borer (CSB) is a significant agricultural pest.
- Benthyloid wasp is a natural enemy of CSB.
Purpose:
- To evaluate the parasitic efficacy of Benthyloid wasp on Chrysanthemum stem borer.
- To determine the optimal release ratio of Benthyloid wasp to CSB for biological control.
Summary:
- Benthyloid wasp demonstrated high parasitism rates against CSB: 83.9% in laboratory and 57.2% in field settings.
- The optimal ratio for releasing Benthyloid wasp to control CSB was determined to be 2:1 (wasp to host).
Impact:
- This research provides valuable insights for developing sustainable biological control strategies against Chrysanthemum stem borer.
- Effective utilization of Benthyloid wasp can reduce reliance on chemical pesticides, promoting environmentally friendly agriculture.
