Scouting of <i>Macrosiphum euphorbiae</i> on tomato plant

Scouting of <i>Macrosiphum euphorbiae</i> on tomato plant

Description: The protocol consists in a visual and non-destructive method with known precision to describe the populations of tomato aphid Macrosiphum euphorbiae in tomato greenhouse, at the plant scale.

Use: The method allows two levels of results: the first level corresponds to the indexes of abundance classes, the second one to the average values from the calibration classes. The first level is perfectly adapted to scouting for pest monitoring aspects or ecological quantitative studies. The second level is useful for biological control, notably to estimate number of beneficials to introduce, knowing the number of pests.
