Biotype and insecticide resistance status of the whitefly Bemisia tabaci from China.
Pest Manag Sci. 2010 Dec; 66(12):1360-6.PM

Abstract

BACKGROUND

Resistance to numerous insecticide classes in Bemisia tabaci Gennadius has impaired field control efficacy in south-eastern China. The biotype and resistance status of B. tabaci collected from these areas was investigated.

RESULTS

Two different biotypes of B. tabaci (B-biotype and Q-biotype) were detected in south-eastern China, and the samples collected from geographical regions showed a prevalence of the Q-biotype and the coexistence of B- and Q-biotypes in some regions. Moderate to high levels of resistance to two neonicotinoids were established in both biotypes (28-1900-fold to imidacloprid, 29-1200-fold to thiamethoxam). Medium to high levels of resistance to alpha-cypermethrin (22-610-fold) were also detected in both biotypes. Four out of 12 populations had low to medium levels of resistance to fipronil (10-25-fold). Four out of 12 populations showed low levels of resistance to spinosad (5.7-6.4-fold). All populations tested were susceptible to abamectin.

CONCLUSION

The Q-biotype B. tabaci is supplanting the B-biotype which used to be ubiquitous in China. Field populations of both B- and Q-biotypes of B. tabaci have developed high levels of resistance to imidacloprid and thiamethoxam. Abamectin is the most effective insecticide against adult B. tabaci from all populations.
