Sugarcane aphids also are present in most fields throughout southcentral and northcentral Kansas, but mostly only in small, scattered colonies (fig. 4). Beneficials are also very common, but it doesn’t seem like there are as many as there have been in the last couple of weeks. This could be because there are substantially fewer corn leaf aphids, in most fields, for beneficials to feed on. Sugarcane aphid monitoring should continue.
