Double Dart

Systematic position. The Double Dart (Graphiphora augur) belongs to the order Lepidoptera, family Noctuidae. This insect is a typical polyphagous species capable of adapting to various environmental conditions and feeding on a diverse range of host plants.

Host range. The pest is characterized by high ecological plasticity. The larvae feed on a wide spectrum of plants, including fruit trees, berry bushes, vegetable crops, and various wild grasses. Among the most frequently damaged hosts are apple trees, raspberries, currants, and various weed species that serve as reservoirs for the pest.

Biology and life cycle. The insect typically completes one generation per year. Late-stage larvae overwinter in the soil or under plant debris. In spring, after hibernation, they actively feed on buds, leaves, and young shoots. Pupation occurs in the top layer of the soil. Adult moth flight occurs in mid-summer, followed by egg-laying on host plants.

Damage patterns. The greatest threat is posed by the larvae, which are nocturnal and tend to remain hidden during the day. They consume buds during the spring opening period, which leads to significant yield losses in fruit crops. In cases of mass outbreaks, the pest can completely defoliate young seedlings and saplings.

• Deep autumn plowing of soil to eliminate overwintering larvae.
• Regular removal of weeds around the field or orchard areas.
• Application of insecticides during periods of high larval activity.
• Use of pheromone traps for monitoring adult moth populations.
