Blackberry leafhopper

The blackberry leafhopper (Typhlocyba tenerrima) is a small insect belonging to the order Hemiptera and the family Cicadellidae. It is recognized as a significant pest in both commercial and amateur fruit production, primarily known for its specialized feeding habits on specific berry-producing shrub species.

This pest mainly affects plants within the Rosaceae family. Raspberries and blackberries are the most frequently infested crops. Both adults and nymphs reside primarily on the underside of leaves, using their piercing-sucking mouthparts to feed on plant sap, which negatively impacts the overall vigor of the host plant.

The biological cycle of this insect involves multiple generations during a single growing season. Overwintering occurs in the egg stage, with eggs embedded in the bark of young canes or petioles. Once temperatures rise in spring, nymphs emerge and begin feeding immediately, progressing through several nymphal stages before reaching adulthood.

The characteristic damage caused by this leafhopper involves stippling or spotting on the foliage. These small, pale chlorotic marks interfere with the plant's photosynthetic capacity.

• Stunted leaf development and premature senescence.
• Reduced fruit yield and poor berry quality.
• General decline in plant vitality.
• Potential transmission of viral or phytoplasma pathogens.

Effective management strategies should combine cultural and chemical control measures. Regular pruning and removal of infested canes help reduce overwintering populations. When monitoring indicates a high threshold of infestation, the application of systemic or contact insecticides is recommended. Always ensure that the chosen products are approved for use on berry crops and adhere strictly to pre-harvest intervals to ensure safety.
