Summary of the Express Pest Risk Analysis for Aleurothrixus (=Aleurotrachelus) trachoides Back, 1912
PRA area: Poland
Describe the endangered area: the entire PRA area. (cultivations of capsicum, tomato, rose)
Main conclusions
Solanaceae species, especially tomato, capsicum and plants of Rosa genre are commonly cultivated in the PRA area.
Rating of the likelihood of pest entry is estimated as moderate to high and establishment as low to high (depending on climate scenario). Additional, there is probability that pest can develop and find suitable conditions in greenhouses. In case of A. trachoides entry in Europe the losses in capsicum and tomato crops will be the highest in The Mediterranean area. The risk of losses in PRA area is associated maily with host plant cultivations in protected conditions.
Rating of the likelihood of impact without phytosanitary measures: high.
Main reason of this situation is import of seedlings and vegetables from area of pest occurrence. The risk will be higher if packings take place close to host plants crops(bunch of tomatoes may be more dangerous because of probably higher number of pests on branches). Another posibble way of pest entry is import of packages as boxes used for harvest and transport from countries where A. trachoides occurs. Correct identification and pest monitoring are nessecary to protect and decrease the probability of pest entry and spread. A. trachoides is a new pest in EPPO region and there is lack of informations about its economic impact.
Systemic and contact pesticides may be used to control whitefly depending on the crop and growing conditions. Also using of soap solution and organic oils may reduce the losses, especially at the begining of infections.
Research is ongoing on the biological methods of pest control by using several Encarsia species and predatory beetle- Axinoscymnus puttarudriahi.
