Caterpillar Communication Adapter II is a CAT group dealer workshop diagnostic tool built to work with Caterpillar heavy vehicles and Caterpillar engines. This adapter connects any computer (notebook or PC) to CAT vehicle or engine and can perform all diagnostic services by cat et adapter (Electronic Technician Caterpillar Electronic Technician) software.
CAT ET is multi languages Vehicle diagnostic Communication Scanner for trucks and heavy duty. Cat Communication adapter ii enable to access Electronic Control Modules (ECMs) from a personal computer.But how a simple virus could control caterpillar behaviour was a mystery. Kelli Hoover of Pennsylvania State University in University Park, who led the research, had a hunch that a gene in the virus called egt could be responsible.
Because the caterpillars normally descend the tree to moult, Hoover figured that their tendency to remain high up when infected by the virus might be because the moulting hormone was being blocked. Her team tested this idea by disrupting the egt gene in the virus. Caterpillars infected with the modified virus returned to the bottom of a tall experimental bottle to die, whereas those infected with the normal, egt-containing, virus died high up the side of the bottle.
