Almond burnet

Systematic position: The almond burnet moth (Aglaope infausta) belongs to the order Lepidoptera and the family Zygaenidae. It is a specialized pest primarily affecting plants within the Rosaceae family, specifically targeting stone fruit trees in temperate climates.

Host plants: The pest primarily infests almond, blackthorn, hawthorn, cherry, plum, and apricot trees. In high-density populations, the larvae can cause widespread defoliation in commercial orchards, leading to significant economic losses for fruit producers.

Biology and life cycle: This moth undergoes a complete metamorphosis. It typically overwinters as larvae inside protective silken cocoons attached to the branches or trunk crevices. In spring, as buds begin to burst, the larvae emerge to feed actively on foliage, completing their development before pupating in early summer.

Damage and economic importance: Early instar larvae skeletonize the leaves by consuming the mesophyll while leaving the veins intact. Mature larvae proceed to devour the entire leaf blade. This extensive feeding reduces the tree's photosynthetic capacity, weakens its vigor, and severely impacts fruit development and yield.

Control measures: Integrated pest management strategies are essential for controlling Aglaope infausta. Cultural practices, such as pruning and removing dead bark where larvae hibernate, are the first line of defense. During the peak larval activity period, the application of approved insecticides is recommended to prevent excessive foliage loss.
