Abstract:

GenSIM is a modelling program for estimating movements of highly mobile insect pests such as heliothis moths and plague locusts. These insects migrate by undertaking nocturnal, wind-assisted flights at heights of a few hundred to over 2000 metres above the ground. They can move hundreds of kilometres in a night, and may move longer distances by flying on multiple nights. The program estimates movements by simulating flights of individual insects. The flight paths of the insects are determined by their flight behaviour and the environmental conditions (particularly wind velocity) they experience during flight. Flights may be simulated in reverse to estimate source areas for specified immigration areas. The two most common outputs of the program are individual flight paths and maps of estimated destination or source areas. These areas are estimated by accumulating the results of large samples of flights. GenSIM is generally run as a component of larger systems rather than as a standalone program. To date, it has been interfaced to the geographic information system ARC/INFO, the scripting language Tcl/Tk and the World Wide Web.
