- Intervention effect A density of 25 mites/leaf was the threshold causing significant decrease of photosynthetic pigment contents and protective enzyme activities in cassava leaves in the laboratory.
- Intervention effect At the 25 mites/leaf threshold, leaf damage was significantly lower than at a higher mite level with calendar sprays.
- Observation The mite density threshold causing laboratory physiological and biochemical changes basically coincided with the threshold causing significant field yield loss.
- Recommendation The authors conclude the optimum threshold for acaricide spray against T. urticae on cassava is 25 mites/leaf.
