In very hot, dry conditions, what insect is most likely causing damage to soybeans?

In very hot, dry conditions, spider mites are known to be particularly damaging to soybean crops. These pests thrive in warm and arid environments, which can stress the plants and make them more susceptible to mite infestations. Spider mites feed by piercing the plant cells and extracting the sap, leading to stippling, discoloration, and decreased plant vigor.

Their presence can be exacerbated during drought conditions, as stressed plants provide a more conducive environment for mite populations to grow rapidly. In contrast, other insects like thrips and leafhoppers are less commonly associated with hot, dry conditions and do not have the same feeding habits as spider mites. Japanese beetles may damage leaves as well, but they are more prevalent in different environmental conditions. Therefore, spider mites are the most likely culprits in situations where soybeans are suffering under high heat and low moisture.
