The pine processionary (Thaumetopoea pityocampa) is a defoliator lepidopter that feeds on the leaves of pine trees.
In general they do not kill trees but weaken them and favor the action of other pests. However, one of the most serious problems these insects create is because the larvae have a lot of tiny hives hairs that are released when disturbed. In contact with the skin, eyes, lips and mucous membranes of people or pets, they can cause significant allergic reactions.
Its life cycle goes through a larval phase, a chrysalis phase and an adult phase. Butterflies appear in summer and make the laying at the end of this period. Each female lays 120 to 300 eggs on the leaves of the pines. At the end of October, the larvae that begin to feed on the leaves of the pines (needles) emerge.
The larvae feed at night, during autumn and winter, grouping in silk bags to protect against the cold. Between the months of January and March they go down to the ground in procession to bury themselves, at the base of the trunks, to move to the chrysalis phase, hoping to transform into a butterfly. In summer, depending on the availability of food, a portion of these buried caterpillars will complete the metamorphosis and transform into butterflies. The rest will do so in later summers as they can stay in this pupa phase for up to six years.

METHODOLOGY TO ERADICATE PINE PROCESSIONARY
Only biological preparations of Bacillus thuringiensis and chitin inhibitor products such as Diflubenzuron are allowed for forest surfaces. Bacillus Thuringiensis (Biological) consists of spores and toxins that cause blood infection and death in all types of caterpillars. It is a selective and biological insecticide, creating harmless to humans and beneficial insects such as bees.
Gimasur recommends that you perform a foliar application of plant protection product (Bacillus Thuringiensis) against pine processionary, being sufficient to control the processionary population of the area. The application of the product will be carried out with hydraulic sprayer and telescopic pressure lances for hard-to-reach areas.
Some areas that may be affected by plagues of pine processionary are facilities with outdoor areas, such as schools, nurseries, parks, cemeteries, forests or outdoor pools, among others.
