“…Its insecticidal activities were obtained as 86%, 66%, and 27%, respectively. In another study, B. thuringiensis FDP-41, B. thuringiensis FDP-42, and B. subtilis EK-7 isolates were also tested against R. simulans, and the mortality rates of these applications were determined as 25%, 42%, and 25, respectively (Gokturk et al, 2018). Yet in another study, it was reported that B. thuringiensis FDP-41 and B. thuringiensis FDP-42 strains could be used as biocontrol agent against Bruchus dentipes (Tozlu et al, 2011).…”

In Turkey, Tinocallis (Sappocallis) saltans (Nevsky) on Ulmus glabra Hudson was detected for the first time, and it was determined that it caused a considerable amount of damage. The study was conducted for the purpose of determining the usability of entomopathogens in the control against it, to avoid the negative effects of chemicals on the environment and human health. A total of 12 bacteria strains were tested for control efficacy and verified: Brevibacillus brevis (2), Bacillus thuringiensis (1), Bacillus thuringiensis subsp. kenyae (2), Bacillus thuringiensis subsp. kurstakii (2), Bacillus subtilis (1), Pseudomonas chlororaphis (1), Bacillus sphaericus GC subgroup D (1) Pseudomonas fluorescens biotype C (1) and 2 Bacillus atrophaeus (1) and 1 fungus isolate (Beauveria bassiana). The trials were carried out in two different forms, under controlled conditions and under field conditions. Data showed that the percentage mortality were 12.84%-100% in controlled and 7.72%-31.79% in field condition over the 72h period. B. thuringiensis subsp. kurstakii (FDP-41), B. subtilis (EK-7) and B. thuringiensis subsp. kenyae (FDP-42) were the most effective bacterial strains against the aphids in controlled conditions. The percentage mortality of these applications was 100% at 48h. in controlled condition. But the effectiveness of B. thuringiensis subsp. kurstakii (FDP-41) was 31.79% at 72 hours in field conditions. On the other hand fungal isolate B. bassiana (ET 10), suppressed the harmful population significantly in controlled conditions (86.64%); however, it was less effective in field conditions (13.04%). As a result, it was concluded in the present study that these bacteria strains may be used successfully as bioagents in the biological control against T. saltans.

“…Mulberry and P. pentagona were used as host plant and harmful insect in this study, respectively (Figure 1b). Bacterial strains CP-1, TV-67C and TV-91C were isolated from Ricania simulans, Rubus idaeus and Graminea sp., respectively in previous studies (Table 1) (Göktürk et al, 2018;Erman et al, 2010) and defined in the MIS based on fatty acid methyl esters. Stock cultures of the bacterial strains were kept in Atatürk University Faculty of Agriculture Plant Clinical Laboratory (AUFAPCL).…”

Pseudaulacaspis pentagona (Targioni-Tozzetti) (Hemiptera: Diaspidae) which has a wide host range, is an important pest causing losses in yield. The insecticides are used for control against this pest but insecticidal control is difficult as scales protect themselves very effectively with hard, waxy armor. Also, the negative effects of the chemicals used in the control against benefical insects and with the increasing awareness on environmental issues, alternative methods were sought. Therefore, this study was performed to develop an alternative and effective control method for this pest by using biocontrol bacteria Bacillus pumilus (TV-67C), Brevibacillus brevis (CP-1) and Bacillus megaterium (TV-91C) under controlled conditions. The death adult number of the pest was recorded and mortality rate was calculated. All of the tested bacterial strains showed mortality rates from 41.68% to 89.04% against the white peach scale under controlled conditions. Consequently, our results indicated that especially B. pumilus strain TV-67C and B. brevis strain CP-1 can be used as biocontrol agents of P. pentagona.

“…The bacterial strains and fungal biocontrol isolate the insecticidal effects of which were investigated in the study were obtained from the Ataturk University Faculty of Agriculture Plant Protection Department Culture Collection. Previous studies have determined the effectiveness of a portion of these agents on different plant pests and pathogens (Göktürk et al, 2018;Erman et al, 2010;Tozlu et al, 2011, Dadaşoğlu, 2013, while others were first tested in this study (Table 1). The bacterial biocontrol strains cultured in the Nutrient Agar (NA; Difco) medium were kept in 30% glycerolcontaining Nutrient Broth (NB; Difco) at -80 o C, while the fungal isolate was kept in slant Potato Dextrose Agar (PDA, Difco) at 4 o C in the Atatürk University Faculty of Agriculture Plant Protection Department Culture Collection.…”

Cottony cushion scale Icerya purchasi Maskell, 1878 (Hemiptera: Margarodidae) is an important pest that inhibits the plant growth and development by sap sucking of the plants, and causes sooty mold in more than 200 plant species, especially in citrus plantation. The present study investigated the biological control of the nymphs and adult I. purchasi, which densely populates the mimosa plants (Acacia dealbata) in Artvin, Turkey. For this purpose, one fungal isolate [Beauveria bassiana (ET 10)] and eight bacterial strains [Brevibacillus brevis (CP-1), Bacillus thuringiensis subsp. kenyae (FDP-8, FDP-42), B. thuringiensis (FDP-1), B. sphaericus (FD-49), B. pumilus (TV-67C), Pseudomonas fluorescens (RK-1773) and B. atrophaeus (RK-1774)] were assessed against the nymphs and adult of I. purchasi under controlled conditions. Fungal and bacterial suspensions were sprayed onto 20 nymphs and 20 adults of I. purchasi in plastic boxes. The death rates of the nymphs and adults were recorded. The B. bassiana (ET 10) caused a death up to 100% and 80% in nymphs and adults, respectively. Moreover, P. flourescens (RK 1773) caused 90.5% death of nymphs and B. thuringiensis subsp. kenyae (FDP-42) presented 88.5% death to the nymphs of I. purchase. However, the use of the bacterial strains was not much successful against the adults, as compared to the nymphs.
