reparation of local protein hydrolyzate from liquid wastes of breweries: a protein bait for the Mediterranean fruit fly Ceratitis capitata

Protein hydrolyzates were prepared locally from breweries liquid wastes. The liquid wastes were cooked for 48 hours, a papain enzyme was added and mixed for 24 hours. Field experiments were carried out to test the attractiveness of the Mediterranean fruit fly (Med fly) Ceratitis capitata to the resulting product. Two orchards (1 hectare/orchard), were selected containing (each) several varieties of citrus fruit trees. Delta traps were used to monitor Med fly populations. The objective of this study is to convert the liquid waste resulting from breweries into substances of economic value (Protein hydrolyzates). Field experiments have shown that locally prepared hydrolyzates are successful, and outperform imported ones. This product will be used as attractive bait for an insect that is considered one of the most important agricultural pests (Med fly) in Syria. The local product will enable us to use it as an alternative to the imported one.This will reflect positively on the sustainable economic development plans in our country.
