Enter maximum and minimum daily temperatures in Celsius in the respective text boxes below and then click the "Get Duration" button to find out the number of days it would take for LBAM to complete its individual stages.
|Total generation time:|
Suppose the daily minimum for the next month or so wil be around 20 C and the daily maximum will be around 30 C. Enter 20 in the left textbox and 30 in the right textbox and you'll get 7 days for the egg period, 31 days for the larval period, 8 days for the pupal period, and 49 days (egg period + larval period + pupal period + 3 days from moth emergence to laying eggs) for the whole generation.
If, at the moment, you have a large influx of moths in your orchard, then you'll know that the larvae will be out in about 7 days(the egg period as predicated by the calculator). If you already have young larvae in your orchard, then you can predict that the next generation moth will be out in 29 days (31 days larval period as predicated by the calculator + 8 days pupal period as predicated by the calculator - 10 days as the larvae you saw may have already completed 1/3 of the larval period).
Insect development durations changes with temperature. Usually the higher the temperature, the faster the development. However, extreme temperatures also slow down development and may ever kill the insect.
For LBAM, the fastest development rate was recorded when the temperature was around 28 C. Try different temperature entries to get a range of development durations.
