cowpea aphid

Catalogue: Ground Cover
Spraying to manage aphid infestations in the northern region does not guarantee increased yields.. Research is beginning to show that controlling aphids may not necessarily lead to higher yields or prevent the spread of viruses... While aphids can transmit damaging viruses to faba beans, trying to control virus transmission by spraying for aphids is likely to be of little use in preventing the spread of non-persistently transmitted viruses, such as bean yellow mosaic virus (BYMV)...

This 'telescoping' of generations allows aphids to reproduce very rapidly when conditions are favourable... In autumn, winged adults move into crop edges where they build up in numbers before moving into other parts of the crops... The timing and number of aphid flights into crops are influenced by late summer- and early autumn- rainfall; good rainfall favours growth of suitable host plants and allows aphids to build up early in the season...
