Özet: Insect species adaptation to different plant species and unfavorable environmental conditions make their lives sustainable and they are among the most living species on earth. Brassicae family are among the most important hosts for polyphagy cabbage whitefly, Aleyrodes proletella L. (Hemiptera: Aleyrodidae). Polyphagy species have the ability to maintain their lives for a long time by feeding on weed species which are alternative hosts during the periods of having no cultivated plants. It is important to know the population of the pest on alternative hosts, in order to create the Integrated Pest Management (IPM) program for A. proletella. Population of A. proletella on weed, Lapsana communis L. (Bieb. Hayek) around collard was monitored in Düzce province during 2017-2018. For this purpose, when the collards were removed and destroyed at the end of the winter season, randomly selected L. communis plants around the gardens were examined and the biological stages (egg, larva, pupae, adult) of whitefly were recorded. Being all the biological stages of A. proletella on weed, L. communis around the collard gardens in the spring in Düzce conditions shows that this weed species is an intermediate host for A. proletella. As a result, although it is known that the controlling the L. communis will cause a decrease in whitefly population, it is estimated that the weed also serves as a host for parasites and predators.
