1) Strawberry Aphid, (Chaetosiphon fragaefolii)
- Aphids are small, greenish-yellow, pear-shaped sucking insects that feed on the sap of leaves.
- These insects can spread viruses from other wild sources, and their feeding can weaken otherwise healthy plants.
- Aphids are more likely to be a problem in weedy beds. Therefore, be vigilant about weed control around your strawberry bed.
- Leafhoppers are small, wedge-shaped greenish-yellow insects that feed on the underside veins of leaves.
- Severe damage causes leaf curling and stunting.
3) Sap Beetles
Sap beetles are extremely common and pose problems when they attack ripening fruits in large numbers.
- They feed largely on soft, overripe, and rotting fruits and vegetables and can be controlled by good sanitation in and around the planting and by harvesting ripe fruits regularly.
- Do not allow the fruit to become overripe. Place plastic funnel traps (plastic soda bottles) in rows filled with vinegar, molasses, and water to capture this pest near plants if necessary.
4) Tarnished Plant Bugs, (Lygus lineolaris)
Tarnished plant bugs cause considerable fruit deformation and excessive seediness in localized areas of the fruit (usually the tips).
- The adults are 1/4-inch long, brown, and can be found around strawberry blooms.
- They are most serious in weedy beds.
5) Two-Spotted Mites, (Tetranychus urticae)
- Two-spotted mites are common pests of strawberries and can seriously weaken plants so that winter damage increases, fewer runner plants are established, and the overall yield and quality of the fruit is reduced.
- The mites are very small, yellowish, and can be found on leaf undersides.
- Their feeding damage causes tiny yellowish-white flecking (stippling) that is visible on the upper leaf surface.
- Where populations are very high, spider-like webs can be found throughout the foliar canopy.
- Mite populations develop early, but severe damage may not be noted until later in the season. Mite problems are more severe during extended periods of hot, dry weather.
6) Spotted wing drosophila (SWD), (Drosophila suzukii)
- The spotted wing drosophila (SWD), Drosophila suzukii, is a small vinegar fly with the potential to damage many fruit crops.
