Abstract

Blatta orientalis and Blattella germanica are the most common pests in the food industry. The aim of this study is the evaluation of new treatment schemes effectiveness as well as the monetary cost, humans and environment toxicity against Blatta orientalis and Blattella germanica. The study was carried out in 28 food units infested with Blattella germanica and Blatta orientalis in Tirana. The duration of the study was 24 months. The treatment efficacy of 2.15% imidacloprid (in gel form) is  tested for 12 months, in thirteen units meanwhile one unit served as a control unit. The  monetary cost of insecticide mentioned was calculated using the quantity and treatment duration of insecticide applied. For this reason, we calculated  the quantity of gel baits used in seven food units as well as the quantity of insecticide in spray form used in seven others food units for a period of 12 months. Technical and safety data sheets were used to assess human and environment safety. Insect elimination was achieved by the end of the ninth week. This study found that in the units which used imidacloprid the short term cost was 21 Euro / unit, while in other units which used the classic method  the cost was 8.3 Euro / unit.  Our study identified that at the units which used imidacloprid the annual cost was 68 Euro while in the other category the cost was 78 Euro.Technical and safety data sheets detected that insecticides in gel form are safer for human and environment. As in analog studies conducted byforeign researchers, we found that  the use of insecticides in gel form is the right choice for Blatta orientalis and Blattella germanica control.
