Summary
The aphid Semiaphis heraclei peaks in May in Shandong, affecting Lonicera japonica. Lambda-cyhalothrin, abamectin, imidacloprid, and pyrethrin show high toxicity, with systemic options like pymetrozine and imidacloprid proving effective for control.
Area of Science:
- Agricultural Entomology
- Pest Management
- Chemical Ecology
Context:
- Lonicera japonica (Honeysuckle) is a significant crop in Shandong, China.
- Semiaphis heraclei (aphid) infestations can severely impact Lonicera japonica yield and quality.
- Understanding aphid population dynamics is crucial for effective pest management strategies.
Purpose:
- To determine the population dynamics of Semiaphis heraclei in Shandong's Lonicera japonica production districts.
- To screen for highly efficient and safe control techniques against this aphid.
- To evaluate the efficacy of various insecticides for aphid control.
Summary:
- The study identified May as the peak emergence period for S. heraclei in Pingyi, Shandong.
- Aphid populations were higher and emerged earlier on the Sijihua variety compared to the Damao variety.
- Insecticides such as lambda-cyhalothrin, abamectin, imidacloprid, pyrethrin, matrine, pymetrozine, and azadirachtin demonstrated high toxicity.
- Field trials confirmed high control efficacy (>90%) for several sprayed insecticides and systemic application of pymetrozine and imidacloprid.
Impact:
- Provides critical data on aphid population dynamics for targeted interventions.
- Identifies effective and environmentally friendlier insecticide options for S. heraclei control.
- Offers practical recommendations for sustainable Lonicera japonica cultivation through efficient aphid management.
