Eco-friendly control method against invasive pest box tree moth, (Cydalima perspectalis (Walker) (Lepidoptera: Crambidae))

Background: Buxus sempervirens (Boxwood) is a type of plant that has economic and cultural significance, danger of extinction due to various factors. Cydalima perspectalis (Walker, 1859) (Lepidoptera: Crambidae), an invasive species, has an important role as a boxwood pest. The inadequacy of the pheromone trap methods recommended to control the pest or the negative effects of chemical insecticides on the environment have led to seeking alternative approaches in this regard. In this study, it was conducted to determine whether entomopathogens can be applied in pest control, the insecticidal effects of Bacillus thuringiensis subsp. kenyae (FDP-8), Bacillus cereus (FD-63), Brevibacillus brevis (FD-1) and Vibrio hollisae (FD-70) bacterial strains at the concentration of 1 × 108 CFU/ml and Beauveria bassiana (Bals.-Criv.) Vuill. (Cordycipitaceae) (ET 10) fungal isolate at the concentrations of 1 × 106, 1 × 107 and 1 × 108 conidia/ml were tested under controlled conditions. Results: As compared the results of the bacterial strains and fungal tested, it was determined that the best results were obtained from in the fungal isolate at the concentration of 1 × 108 conidia/ml. After 192 and 216 h. of observation, the 1 × 108 CFU/ml of bacterial strains: B. cereus FD-63, B. brevis FD-1 and V. hollisae FD-70; also, 1 × 108 conidia/ml concentration of ET 10 fungal isolate of B. bassiana control C. perspectalis caused mortality rate of 100% under laboratory conditions. Conclusion: Future studies of these microorganisms against this pest in the field, may be an important alternative method to control this pest

Biological control of pine sawfly (diprion pini l.) and molecular characterisation of effective strains

Diprion pini is one of the most important pests in forest trees around the world. Also the pest was determined in pine forests around the Turkey, causing outbreaks in some regions. Therefore, this study aimed to develop bacterial biopesticides, which can be used to control Diprion pini remarkably and at the same time which do not threaten the environment and human health. Bacterial strains which were effective against different pests in some studies were used. Their insecticidal effects were tested on larvae of Diprion pini in vitro on petri dishes. Seven days after applications, some of the tested strains showed more or less insecticidal activity against this pest. The highest activity was obtained for strains FD-17 and FD-1causing 66.7-80% mortality, respectively. The activities of the other bacterial applications were not statistically different from that of the negative control. In conclusion, strains FD-17 and FD-1 are good candidates for use as biological control agents against this economically important pest. These effective strains were characterized to the species level by 16S rDNA sequence analysis. According to the results, both strains have been identified as Bacillus atrophaeus
