Colorado potato beetle

Editorial diagnosis

Diagnosis overview

Colorado potato beetle attacks potatoes and other nightshades. Adults and larvae feed on leaves and can heavily defoliate plants.

In gardens, Colorado potato beetle can occur on plants including Eggplant, potato. In the available profiles, it is linked mainly with Fruit vegetables, Root vegetables.

Its importance depends on how quickly it spreads and whether seedlings, shoot tips, flowers, or fruit are affected. Remove adults, eggs, and larvae early before heavy leaf loss develops.

Inspect leaf undersides, shoot tips, and the soil around the plant at different times of day. Eggs, larvae, droppings, webbing, or slime trails are often more diagnostic than one damaged leaf.

A common mistake is to treat feeding damage without checking the animal, eggs, larvae, time of activity, and affected plant parts.
