دشمنان طبیعی سفیدبالک Aleuroclava jasmini sensu lato (Hem.: Aleyrodidae) در فضای سبز شهر تهران

Since the summer of 2014, the outbreak status of Aleuroclava jasmini sensu lato on white mulberry trees in Tehran is observed. It has caused physical inconvenience to citizens in different public and private places, as well as the damage it can cause to trees in the city's green space as an herbivorous insect. Nowadays, the conservation and enhancement of biodiversity is of particular importance in the green spaces of urban environments due to the limitation in the application of chemical pesticides. In this regard, and in order to identify the natural enemies of this whitefly, continuous monitoring was carried out in the green space of Tehran during 2015-2017. For this purpose, standard sticky yellow cards (25 × 10 cm) were installed on mulberry and olive trees (from mid-autumn as a secondary host) and the trapped useful arthropods (parasitoid wasps and predators) were studied. In field surveys, the predators of this whitefly were also directly collected using an aspirator. Furthermore, the parasitised forth instar nymphs of A. jasmini were collected and kept in the laboratory conditions until the parasitoids emerged. The parasitoid wasps were slide-mounted for identification. In the current study, 16 predator species and two parasitoid wasps were identified as follows. The species indicated by an asterisk (*) were found to be effective in controlling this pest.
