The guarantee of quality treatments depends first and foremost on the quality of the group of experts mandated and their energies allotted to this program.

Main Concerns

Since work begins in springtime and that immediate intervention is crucial for obtaining good results, the mandated firm must possess a work force ready and present in the sector. The execution of treatments should never be dependant on the availability of teams or equipments, without which the project's quality control would be compromised.

The multidisciplinary team's main concern is to establish a respected position in the activities sector and does this by offering first class service and superior target objectives.

The highly qualified personnel; biologists with biological control experience is one of the keys to success of our team. Larval population surveillance and the launching of control operations cannot be left to chance. Only the sustained monitoring over the entire territory allows the proper evaluation of larval development and thus the exact timing of the launch of control operations.

Using state of the art technologies such as photo-interpretation, remote sensing, GPS recordings, data analysis using ArcInfo and the digitization of maps, our team is clearly distinguished form the competition and our informed clientele rest assured.

Aerial photo surveillance during snow melt is an excellent tool that provides a complete view of the territory. Photo-interpreters can read aerial photographs and precisely identify all potential breeding habitats (larval sites). It is however, very important to couple ground-level data and aerial data in order to reassess zones containing very small breeding sites. These small sites often contain surprisingly high larval densities that, in addition have asynchronous larval development rates due to greater temperature changes in smaller habitats causing increased metabolism of the larvae there.

In order to impart all relative information of the biological control programs, a Public Information Notebook (P.I.N.) is presented to the town at the start of the project. This notebook will clearly present, with the help of aerial photographs, maps, figures and short texts, the different elements of the program. Over the course of the season, new pertinent information will be incorporated into the notebook, including nuisance tests data which will be performed regularly. We suggest that the P.I.N. be made accessible to the public in municipal offices and if possible, put on the municipal web site. Citizens could then obtain pertinent information rapidly relative to the program and could add their comments in a reserved space.

Monitoring

After 24 to 48 hours of treatment, mortality rates should reach 100%. After 24 hours, the presence of a few dying larvae is normal, but if larvae persist after 24 hours, these sites should be treated again. These verifications are a part of the coordinator's daily tasks. Dosages are then adjusted accordingly, by keeping with the ultimate objective of 100% mortality using minimal dosage.

Nuisance testing

Nuisance testing brings satisfaction of a job well done. By sampling the adult population between two similar and predetermined stations, the population decline can be quantified. One station is situated within the town, (e.g., park, beach, ball park) while the other, a similar site, is situated outside the town (e.g., neighbouring town park). Accompanied by a town representative acting as a witness, nuisance testing consists of waiting at a station for 5 minutes, then sweeping an entomological net, sampling adults present (done by horizontal figure eights) during 5 minutes. This test demonstrates treatment efficiencies, while also helping to determine the origin of adults and to target any treatment gaps.

Corrective Measures

The diverse quality controls performed can show certain weaknesses or problems (e.g., nuisance zones, product failures, incompetent workers). In such cases it is of utmost importance to react quickly, to correctly identify the problem and to bring about appropriate corrective measures.

Evaluation

Every appointed member of the team must have their work evaluated. Technicians and team leaders are evaluated by the coordinator, while the former will also give in return their assessment of the coordinator. This double evaluation gives, if need be, the supervisor information to bring about corrective measures quickly. This supervisory measure helps prevent any litigation, to strengthen the team spirit and to offer better services.

Group DESFOR's Quality Assurance Program ISO 9001

The group DESFOR possesses a Quality Assurance system based on international standards of ISO 9001: 2000 and has been certified since January of 1999.

The enterprise's general objectives include taking all necessary measures to ensure that employees and clients are aware of its firm commitment to the quality of its products and services.

Quality Policy

The management has elaborated a quality policy by which it strives to reach clients' objectives and to allow them to profit from its qualified personnel by offering quality counselling services at a concurrent price for the majority of contractual agreements.

System of Quality

The group DESFOR has established and maintains a documented Quality system that assures clients' demands are met. This system comprises a Quality manual, working procedures, Quality guidelines, working instructions as well as procedures necessary for accomplishing Quality control. The system allows planning and continual improvement to the procedures to assure that clients' expectations are met.

Functioning of the System of Quality

In order to support the activities of the enterprise, the group DESFOR has established coherent working procedures respecting ISO 9001 norms and in line with Quality principles of the enterprise.

To ensure that we meet quality demands, we have established service quality standards of working procedures, so that our service is acceptable to our client. The planning of this is documented under various forms.

Quality guidelines are established as pertains to written procedures appropriate to each activity or process as well as the identification and acquisition of all means to master activities, processes, equipment and skills that can be necessary to reach required quality standards such as:

  • Keeping up to date on techniques for mastering quality, control and experiments;
  • Identify adequate monitoring at appropriate phases of the delivery of service;
  • Identify and prepare reports on quality.
