Peanut stripe virus infection on soybean and its transmission to Peanut Stripe Virus (PStV) has been reported to have other host plants than peanut, but very few studies have been done on infection of soybean plant by the virus and transmission of the virus from soybean to peanut by the aphids. Soybean plants showing mosaic symptoms similar to those produced by artificial inoculations of soybean with PStV were collected from Cikeumeuh Experimental Farm, Bogor. A laboratory and glasshouse experiment has been done from November 1990 to January 1991 at Bogor Research Institute for Food Crops (BORIF). Virus transmission from the infected soybean plants and peanut plants infected with PStV to 7-day old peanut seedlings were done using Aphis glycines and A. craccivora which have been fasted for 1 hr. Serological tests using the ELISA technique and host plant inoculation using bean cv. Top Crop were also done to confirm identity of the virus infecting the soybean plants. The results indicated that the virus infecting the soybean plants was PStV. There was no difference in symptoms produced by PStV from soybean and PStV from peanut. Both A. glycines and A. craccivora could transmit PStV from soybean to peanut or from peanut to peanut, but its effectiveness of transmission differs from one another. A. glycines was more effective in transmitting PStV from soybean to peanut, while A. craccivora was more effective in transmitting PStV from peanut to peanut.
