Aphis gossypii Glover (Hemiptera: Aphididae), also known as the cotton aphid, is a notable pest of several crops. Its damage can be direct and indirect. The direct damage is due to its feeding, which causes leaf shriveling, deformation of shoots, and loss of plant vigor. The pest's indirect damage is through virus transmission to cotton. In Brazil, A. gossypii is considered as a pest to several crops, but there are no references to infestations of this aphid in soybeans. The objectives of this manuscript were to report the presence of A. gossypii infesting and colonizing soybean crops in São Paulo state, Brazil, and to alert the scientific community and farmers about this possible new pest in Brazilian soybean fields.
