Abstract

Blattella germanica and Blatta orientalis are the most common insects found in food industry, houses, offices, hotels, schools, etc. The aim of this study is the evaluation of gel baits efficiency (2.15% imidacloprid) against Blatta orientalis and Blattella germanica in albanian food units. The study was carried out in Tirana from June 2012 to June 2013 in 14 infested supermarkets, 13 of which were treated with 2.15% imidacloprid while 1 served as control unit. Monitor traps and visual inspection were used to estimate pre and post-treatment insect’s density. The latter in treated units was reduced compared to the control unit. There was a decrease since the 1^st week while the total elimination was achieved by the end of week 9. The obtained results indicate that 2.15 % imidacloprid gel baits are more efficient to eliminate Blattella germanica and Blatta orientalis. However, these results contradict the fact that dust and spray insecticides are more effective. On the other hand, gel baits are considered a valuable choice in Albania also for the control and eradication of Blattella germanica and Blatta orientalis from infested area. It is regarded safe for humans and the environment compared to spray or dust insecticides.
