Description

Visual size estimation of treehopper nymphs using reference cards with actual nymphs of known sizes glued to cards, calibrated weekly with caliper measurements of sample nymphs.

Typical Equipment

• index cards with reference nymph sizes
• 0.02 mm caliper

Output Measurements

• nymph instar stage
• nymph size distribution
• average instar per plant
