Laboratory of Entomology

Objectives
  • Study and biological approach of pests control of Olives, Citrus, Vegetables, Subtropical Plants and other crops of Crete.
  • Study of insect and mite morphology and biology, the extent of damage they cause and the relation of these harmful enemies with the environment.
  • Mass rearing of beneficial insects for biological control and enrichment of the beneficial fauna of Crete.
  • Study of the effectiveness of chemical as well as organic insecticides and of alternative techniques of integrated control of pests.
  • Application of alternative methods of chemical control of pests in frames of Integrated Crop Production.

Results
  • Indentification and studies of the new for the area pests of citrus (white flies, moths, thrips, soft scales, miridae etc) and control with biological methods.
  • Biological and ecological characteristics of the major insect pests of Olive, Citrus, Vegetables, Subtropical Plants and other crops of Crete.
  • Effectiveness of non-chemical methods against pests.
  • Introduction of beneficial insects as well as release them for the biological control of specific insect pests.
  • Tests of new products which have been carried out for the control of crop pests of the area resulted in the reduction of chemicals used for this purpose.
  • Effectiveness of new products and application of mass trapping for the control of olive fruit fly.
  • Identification of natural enemies (parasites, parasitoids and predators) of the major crop pests of the area and study their contribution to the reduction of damage.
  • Study of the man interference to the beneficial fauna.
  • Many beneficial insects were released to orchards all around the country, especially to Crete and Southern Greece.
  • Sample analysis was done and instructions given to Public organisations, Cooperatives and individual farmers.
Research Projects
