Per cent Egg Incubation undergone

This module essentially employs the temperature-growth model (Figure 17) of desert locust based on experiment carried out by Symmons et al., 1973. The percent incubation per day is calculated against daily ambient temperature from the model and integrated over the period of interest. If the percent development value exceeds 100 it prompts that incubation is complete. Besides it also compares with thermal degree days required for DL to complete its incubation. This gives idea about the degree of development undergone till date since it's reporting in the field. Here the inputs required are date of sighting of egg pods in the field along with approximate development till that

Figure 17: Air temperature vs per cent egg incubation of desert locust time and the date on which percent incubation is sought. For generalization the model uses the growth curve of DL but with availability of species specific growth curve choices could be given to the users for selection of model.
