Pygnet is a species belonging to the order Hemiptera, specifically in the family Cicadellidae. It primarily infests cherry blossoms, paste stems, azaleas, and other ornamental plants. Both adult and nymph stages feed by sucking sap from the underside of leaves, causing pale spots on the upper surface. Additionally, their dark fecal droppings appear as small, freckle-like spots on the leaf backs, making them easy to detect. Severe infestations can lead to premature leaf drop, affecting plant health and appearance.
In northern regions, Pygnet completes 4–5 generations per year. Adults overwinter in leaf litter, branches, cracks, weeds, and soil crevices. They become active in early April of the following year, flying to host plants for feeding. Eggs are laid on the underside of leaves, near the main veins. By mid-May, nymphs emerge and develop in overlapping generations. The most severe damage typically occurs between July and August. As autumn approaches, adults begin searching for suitable overwintering sites, usually in late October.
Newly hatched nymphs are relatively inactive and tend to cluster together, which can help in early detection. Proper management is essential to prevent population outbreaks.
Control measures include:
1. Removing dead branches, fallen leaves, and weeds during winter to eliminate overwintering adults.
2. Providing shade and proper watering during summer to reduce stress on host plants, thereby lowering infestation risks.
3. Applying insecticides such as 80% dichlorvos EC at 1000 times dilution, 40% dimethoate at 1000 times, 50% carbosulfan (CASS Loose) at 1000 times, or 50% phoxim EC at 1000 times during the early stages of infestation, especially when the first generation of adults appears.
These strategies, combined with regular monitoring, can effectively manage Pygnet populations and protect ornamental plants from damage.
