The lesser peach tree borer, scientifically known as Synanthedon pictipes, is a species of moth belonging to the family Sesiidae. This insect is primarily known for its destructive impact on various fruit trees, particularly peach and cherry trees.
The lesser peach tree borer is relatively small in size, with a wingspan of around 1 inch. It displays brownish-gray forewings with darker bands and white or light brown hindwings. The adult moths typically emerge from pupae during the late spring or early summer.
This moth species is considered a notorious pest, as its larvae cause significant damage to the bark and wood of fruit trees. The female moth lays her eggs on tree trunks or branches, and once hatched, the larvae bore into the tree and feed on the inner bark, sapwood, and cambium layer. This feeding activity disrupts the tree's nutrient and water transport system, leading to weakened and stunted growth, dieback of branches, and overall decline in tree health.
Infestations by the lesser peach tree borer can ultimately result in the death of susceptible fruit trees if left untreated. Therefore, early detection and control measures are crucial for tree preservation. Integrated pest management techniques, such as regular monitoring, timely pruning, and the use of appropriate insecticides, are often employed to combat the lesser peach tree borer and minimize its impact on fruit tree orchards.
