Survey results: Factors of development of bio<strong>control</strong><br />
The exploitation of the questionnaires was somewhat difficult due to the large variety of farmers<br />
<strong>and</strong> situations. Additionally, several open ended questions were introduced to collect opinions on<br />
possible additional gaps <strong>and</strong> opportunities which were not mentioned in the form.<br />
Qualitative analysis. In a first step, the analysis of the responses led to the identification of 12<br />
factors deemed to have a significant influence on the future development of <strong>biological</strong> <strong>control</strong><br />
Nine factors with a positive influence:<br />
o Ability of manufacturers to invest in R&D<br />
o Financial strength of manufacturers<br />
o Direct involvement of leading distributors<br />
o Pull from the fresh food wholesalers <strong>and</strong> from the food industry<br />
o Dem<strong>and</strong> from consumers <strong>and</strong> NGOs<br />

o Availability of Decision Support Systems (DSS)<br />
o Regulatory obstacles to chemical pesticides<br />
Three factors with a negative influence:<br />
o Regulations not adapted to Biological <strong>control</strong><br />
o Discovery of novel effective <strong>and</strong> safe chemicals<br />
o Development of new resistant crops<br />
Quantitative analysis. In a second step, a quantitative analysis was conducted to estimate the<br />
influence of the identified factors. For this, 320 contacts (50% of the sample) were requested to<br />
