How to Identify Aphids
To effectively manage aphids, it is important to be able to identify them. Luckily, unlike other pests, aphids move at a leisurely pace, making them easier to spot and identify.
Aphids are small insects, measuring around 1 to 3 millimeters in length, with soft bodies and a range of colors including green, yellow and black. They have long antennae protruding from their heads and two tube-like structures called cornicles on their hind end, which they use to release defensive substances.
Distorted leaves, such as curling or cupping, are clear indicators of aphid feeding. Aphids inject toxic saliva into the leaves as they feed, leading to deformities and curling.
Aphids also excrete a sugary substance called honeydew, which can accumulate on the leaves and stems of wheat plants, attracting ants and further damaging crops. Regularly inspecting wheat fields for sticky honeydew serves as a clue to the presence of aphids. Identifying and addressing this issue early on can prevent further damage and ensure a healthy wheat harvest.
