Table 2 Mobile phase mortality rate due to insecticides for different application frequencies and the corresponding characteristic time
Appl. frequency | \(\mu _1^i\) (1/day) | \(t_{char}\) | Duration of effect |
|---|---|---|---|
Once a day | 6.86 by application | 3.5 (h) | |
Twice a week | 24 by application | 1 (h) | 30 (min) \(\approx\) 0.02 (day) |
Once a week | 48 by application | 30 (min) | |
Every two weeks | 96 by application | 15 (min) |
