Bacillus thuringiensis (Bt) has a significant impact on biological pest control because of the insecticidal activity through its parasporal inclusion bodies (crystal proteins). Fig is an economically important plant in Turkey; agricultural pests result in a considerable economic loss in fig quality and cultivation. The aim of this work was to isolate, characterize, and determine the lepidopteran toxicity of Bt obtained from fig groves in Aydın Province. A total of 606 colonies (out of 1167) obtained from 380 samples were identified as Bt based on parasporal crystal formation. The highest Bt index of 0.60 was observed in the Kuyucak region. …

Spodoptera littoralis (Boisd.) (Lepidoptera: Noctuidae) is one of the most destructive pests of several vegetables and fruits worldwide. In spite of various control methods, this pest has still continued to cause significant damage. In this study, the culturable bacterial flora of S. littoralis was determined. New isolates from S. littoralis, as well as 12 different Bacillus isolates belong to 5 species that were previously isolated from different pests, were tested on S. littoralis larvae. In total, 9 bacteria were characterized based on their morphological, biochemical, physiological, and molecular characteristics. The bacterial flora of S. littoralis was determined as Flavobacterium sp. …
