Chestnut tortrix

Chestnut tortrix

Cydia splendana

A species of Locallapstore, Also known as Marbled piercer, Chestnut fruit moth

Cydia splendana, the chestnut tortrix, is a moth of the family Tortricidae. It is found in Europe. It is also known as the acorn moth, but this can also refer to Blastobasis glandulella from North America, which belongs to the more primitive family Blastobasidae. The wingspan is 12–16 mm. The moth flies from May to September depending on the location. The larvae feed on oak and sweet chestnut, and perhaps also Juglans species. The larvae develop mostly in mature chestnut fruits.

Life Cycle of Chestnut tortrix
Egg The egg of chestnut tortrix marks the beginning of the life cycle. These eggs are usually laid on host plants and are small, oval, and initially pale but may darken over time. They serve as a protective case for the developing embryo.
Larva Upon hatching, the larva of chestnut tortrix emerges as a caterpillar with a primary focus on feeding and growth. It has a worm-like appearance, and its coloration typically matches its environment for camouflage. The larva undergoes several molts, increasing in size each time.
Pupal After enough growth, chestnut tortrix enters the pupal stage. It forms a cocoon or chrysalis, and significant internal changes occur. The pupa's color can vary but often blends with the surroundings. This is a non-feeding, restful stage where the insect transforms.
Adult Emerging from the pupa, the adult chestnut tortrix's development is marked by the presence of wings and functional reproductive organs. The body is fully formed and hardened, and the adult is mobile, focusing on reproduction and may display sexual dimorphism.

How Can You Attract Chestnut tortrix
Pheromone traps are often effective because many moth species are drawn to specific sexual attractants. For chestnut tortrix, the trap food would consist of species-specific pheromones or host plant volatiles to lure them.
Rectangle
Habitat Preferences of Chestnut tortrix Through Different Life Stages
The larvae of chestnut tortrix are commonly found inside the twigs and branches of oak trees, where they burrow to feed on the internal tissues. Searching for these larvae would involve inspecting damaged or wilted twigs on oak trees. Adult chestnut tortrix prefer habitats with an abundance of host plants, such as oak forests, orchards, and wooded areas, and they are usually observed when they come out to mate and lay eggs on the tree bark or leaves during suitable months, primarily in late summer and autumn. To find the eggs or pupae, one would examine the crevices of bark or leaf litter beneath the host trees, where the eggs are discreetly laid and the larvae later pupate.

When is the Best Time to Observe Chestnut tortrix
The best time to find adult chestnut tortrix is usually at dusk or during the night when moths are most active. The timing may vary based on the specific activity patterns of chestnut tortrix.

Agricultural Pests

The larvae of chestnut tortrix can cause mild to severe damage to a variety of fruits by boring into tissues, which impairs crop quality and yield. Infestations can lead to significant economic losses for farmers, and extensive damage may also result in higher prices for consumers due to reduced market availability.
