Development and efficacy determination of a catch trap (EGE-TRAP) in control of the pine processionary moth Thaumetopoea pityocampa (Schiff.)

Due to fast growing, tolerant ecological demands, existence of optimum conditions in the regions Marmara, Ege and Akdeniz, Redpine (Pinus brutia Ten.) became in first place in Turkey’s Forestry and this caused an increment in monoculture plantation. Accordingly, The pine processionary moth (Thaumetopoea pityocampa (Den. & Schiff.)(Lep., Thaumetopoeidae) has become prevalent in these areas and furthermore  the pine processionary moth caused epidemics in wide areas due to suitable climatic conditions.

The pine processionary moth cause damage in all Mediterranean basin and economical losses by decreasing annual increment in conifers and human health problems. 

With this work is aimed to develop a new trap for controlling of pine processionary moth and determine its efficacy and cost. Utilizing feed and housing habits of the moth, it is intended that they are caught in the traps. After finishing their feeding mature larvae desire to become pupa by returning to soil in early summer. This return occurs in convoys over tree stem downwards. During this descent, catch of mature larvae will be ensured in funnel shaped trap mounted on tree stem. They will not be able to become an adult because of stopping reach to soil of mature larvae and become a pupa in summer. In this way population of next year generation will be decreased, and also natural enemies of the moth either live on it or feed with it will return to nature.

This designed new trap will be applied to the trees with a diameter range 8-35 cm and endure at least 5 years in external conditions. It will prevent increment losses about 20-50% annually by controlling population in a short time. In addition it will be prevented from negative effects on human health and loss of material and manpower.
