Pasiphila

Systematic position: the genus Pasiphila belongs to the family Geometridae, order Lepidoptera. These moths, often referred to as pug moths, are recognized for their larvae, which pose a significant threat to various agricultural and ornamental plants by feeding on their reproductive structures.

Host plants: Pasiphila species primarily target plants within the Rosaceae and Asteraceae families. They are frequently recorded as pests on fruit trees, such as apple, as well as various garden perennials and flowering shrubs, where they target the developing buds and blossoms.

Biology and life cycle: the life cycle follows a complete metamorphosis: egg, larva, pupa, and adult. Eggs are laid on or near the buds. Upon hatching, the larvae immediately begin feeding, often boring into the flower heads to consume the internal parts. Pupation typically occurs in the soil or protected crevices near the host plant.

Nature of damage: the damage caused by larvae includes the destruction of stamens, pistils, and petals. This results in stunted growth, malformed flowers, and significant reduction in fruit set. Because the larvae often match the color of the petals, they can remain undetected until the flower is completely destroyed from the inside.

Control measures: management strategies should focus on early detection before the larvae penetrate the buds.

• Regular visual monitoring of flower buds in spring.
• Application of selective insecticides during the early larval stages.
• Use of biological control agents like Bacillus thuringiensis.
• Soil cultivation around plants to disrupt the pupation cycle.
