title: [Use of entomopathogenic fungi to degrade wax secreted by Ceroplastes japonicus].
abstract: OBJECTIVE
  We used entomopathogenic fungi to degrade insect wax.
  
  
  METHODS
  We used four fungal strains, Lecanicilliurn lecanii V3. 4504, V3. 4505, Beauveria bassiana FDB01, and Metarhizium anisopliae TSL06. Wax coverings of female adults of Ceroplastes japonicus Green (Insecta: Hemiptera: Coccoidea) were used as the sole carbon source in the mineral medium.
  
  
  RESULTS
  All of the 4 strains could grow, reproduce, produce enzymes, and degrade wax. During a 7-day culture, the highest lipase activities of the 4 strains, V3. 4504, V3. 4505, FDB01, and TSL06 were 0.128 +/- 0.017, 0.056 +/- 0.002, 0.124 +/- 0.011, and 0.149 +/- 0.005 U/mL, respectively. The dehydrogenases activities of the 4 strains were 0.075 +/- 0.003, 0.074 +/- 0.003, 0.061 +/- 0.04, and 0. 066 +/- 0. 002 U/mL respectively. The degradation rates of wax by the 4 strains were 18.20 +/- 0.019, 11.00 +/- 0.011, 15.4 +/- 0.017, and 23.10 +/- 0.031%, respectively.
  
  
  CONCLUSIONS
  The 4 strains could depredate wax of C. japonicus.
