Graphosoma lineatum(Hemiptera: Pentatomoidae) is a polyphagia that feeds on plants from the Apiaceae family, includingFoeniculum vulgareMill.,Daucus carotaL.,Ferulago campestris(Besser) Grecescu. It is reported as an important pest in our country, especially in anise production areas. In general, pests prefer generative organs of plants and harm them by feeding on maturing or matured seeds. Chemical control methods are usually preferred in the control of pests. The adverse effects of pesticides on humans and the environment enhance the importance of biological control. For this reason, possible biological control efforts against pests should be produced as an alternative to chemical control. For this purpose, commercially available biocontrol products including Nibortem (Verticillium lecani), Bio Magic (Metarhizium anisopliae), Nostalgist SL (Beauveria bassiana) and Priority SL (Paecilomyces fumosoreus) have been used against pests.Graphosoma lineatumadults used for the cultures in the experiment were collected by hand fromD. carotaplants found at the edge of the practice area of Ondokuz Mayis University Agricultural Faculty. In the study, all the biocontrol products were applied by spraying a dose of 250 ml \ 100 lt water directly on to theG. lineatumadults. Experiments were conducted in 5 repeats and with 10 individuals. The study was checked daily and dead individuals were counted, and the counting continued for 8 days. As a result, it has been demonstrated that commercially available biocontrol products can control biocontrol the pests in question. As a result, we observed at the end of 8th day, the efficiency ofB. bassianawas 100% while the mortality rate ofP. fumosoroseus, M. anisopliae,andV. lecaniiwere 95.45%, 81.82%, and 68.18%, respectively. The isolates of Akca-2 and 27-1A were efficient at 90.91% and 95.45% respectively. Lethal time (LT) values were as mentioned below; LT(90)values were; 1.43 days for Thiacloprid & Deltamethrin, 1.68 days forS. spinosa, 5.85 days for 27-1A, 6.15 days for Akca-2, 6.87 days forP. fumosoroseus, 6.95 days forB. bassiana, 6.96 days for Azadirachtin, 8.54 days forM. anisopliaeand 8.93 days forV. lecanii. We concluded thatB. bassiana,P. fumosoroseus,S. spinosaand the isolates from 27-1A, Akca-2, Azadirachtin had as a similar efficiency as Thiacloprid & Deltamethrin had. As a result, entomopathogenic fungi, bacteria and Azadiractin used in this study can be used againstG. lineatumadults for organic control.
