Key issues in DL control

The major issues related to DL control can be summarized as follows.

• Acquisition of bio-physical information from vast inaccessible and hostile terrain (locust habitats) using satellite remote sensing technology with better temporal sampling capability.

• Parameterization and accurate translation of remote sensing information in relation to ground segment for model input.

• Use of spatial variables for process modeling and subsequent field validation.

• Bio-climatic modeling for locust physiology and migration based upon historical locust events and ground intelligence.

• Operationalization for forecasting of high frequency breeding areas and flight behavior.

Satellite remote sensing helps to examine relationships between distributions of insect pests, rainfall and green vegetation in the seasonally dry tropics. For migration and dispersal modeling there is a need for studying historical records for plague development and forecasting. Current weather data could help to examine downwind airborne dispersal of insect pests over a range of temporal and spatial scales. Based upon the survey of ecological conditions in potential breeding and outbreak areas, aerial and ground survey is organized that become potentially suitable after rainfall incidence. Following the survey operation strategies are chalked out to control DL populations when exceeds above a specific threshold limit, mainly in known outbreak areas.
