SYSTEM FOR THE EARLY DETECTION OF FOREST PESTS
The exotic invasive species represent one of the greatest threats to biodiversity. Infested Roundwood, packaging and storage timber have been the vehicle that has allowed the invasion of many species of bark beetle, or pathogens vectorised by them. The NIMF15 normative has tried to put a stop to these invasions, although a constant vigilance to detect invasive species is necessary.
Amongst these species the perforating coleopterons are highlighted, which are frequently intercepted in ports all over the world. In accordance with Rassati et al (2014), the development of early detection methods is a crucial step when rapid response programmes are implemented, so that these exotic species can be rapidly detected/identified and the plans of action can be applied in time.
For this purpose, it is essential to have a tool with enough plasticity to attract and capture the largest number of species possible. The CROSSTRAP® DETECTION SYSTEM is made up of a CROSSTRAP® MINI trap baited with kairo-pheromonal attractants a-pinene, Ethanol, Ipsdienol and Ipsenol. This system is capable of attracting a large number of species (Gallego and Campo, 2010). Its versatility also allows live captures (with dry collection cup) or wet captures (collection cup for wet captures).
EARLY DETECTION OF FORESTS PESTS
For the early detection of invasive species, at least 1 baited CROSSTRAP® MINI trap should be installed in areas of high risk from exotic species of sapro-xylophagous and beetles entering, such as, Border Inspection Points, Customs warehouses, ports or airports with transport of goods.
For early detection it is recommended to opt for wet captures, given that it allows for the precise identification of the specimens. For this, the collection cup must be filled with 10 ml of propylene glycol diluted to 10 or 20%. As an alternative, car antifreeze can also be used. This liquid is used to kill the captured insects and preserve them, as long as the antifreeze does not get too diluted by the rain. If it does get diluted it must be replaced. It is recommended, as a minimum, that the captures be collected fortnightly.
The traps can be installed in open areas inside the facilities, hanging from artificial or natural supports. It is also recommended to install between 1 and 10 traps in forests closest to the areas studied, in order to increase the efficiency in detection.
INSECT FOREST COMMUNITY MONITORING
The CROSSTRAP® DETECTION SYSTEM can also be used for monitoring species and communities of sapro-xylophagous forest insects (in a general sense) in forests.
This system is currently being used in the quality monitoring and forest health networks set up in three Spanish Autonomous Communities; the ESFP network (Autonomous Community of the Region of Murcia), the MUFFET network (Government of Autonomous Community of Valencia) and the Balearic Network of evaluation and monitoring of forest damages (Government of the Balearic Islands).
This type of monitoring is based on the set-up of networks of low density trapping: one point in each type of ecosystem, in order to cover the biggest part of environmental variability of the area of study.
The sampling areas are carried out with continuous registers of temperature and rainfall and band dendrometers. These networks carry out periodic controls, generally monthly to collect the captured insects and download the information.
