Australian researchers have discovered that the blue alfalfa aphid, which damages legumes by sucking plant sap, is developing resistance to insecticides. This resistance poses a global threat to agriculture, as this pest is distributed worldwide and has been found to have moderate resistance to multiple groups of insecticides. The researchers recommend alternating between different types of insecticides, exploring non-chemical control options, and using crops bred to be resistant to aphid feeding to manage the blue alfalfa aphid and reduce its resistance to insecticides.

Acyrthosiphon kondoi, the blue alfalfa aphid or blue-green aphid, damages legumes, particularly alfalfa, clover, and lentils, by sucking the sap from the plants, and is distributed worldwide. Australian researchers are warning of a global threat as blue-green aphids develop resistance to insecticides. As AgroPades reports, researchers in Australia have documented resistance to insecticides in field-collected populations of the blue-green aphid Acyrthosiphon kondoi for the first time. Evatt Chirgwin, an evolutionary biologist at Cesar Australia and an author of the study, explained that the study was prompted by reports that conventional insecticides were unable to control A. kondoi populations. “Our main motivation was to help Australian growers understand the new challenges of pest management. Australian growers have traditionally relied on two types of insecticides (organophosphates and carbamates) to protect their legume crops against A. kondoi. However, in recent years, many ...
