Titanate-Bacillus Nanocomposite as a Novel Nanopesticide for Cotton Leafworm

Author(s): Zaki AM, Zaki AH, Farghali AA, Abdel-Rahim EF

The cotton crop is one of the most important strategic crops in Egypt, but unfortunately there are several types of insect pests which are very harmful to this crop. One of these pests is cotton leafworm Spodoptera littoralis (Boisd.) (Lepidoptera: Noctuidae) which causes damage to leaves and hence decreases the crop yield. One of the commonly used biopesticides is Bacillus thuringiensis subspecies Kurstaki (BTK), the main problem of using this biopesticide is that; it gives low activity towards cotton leafworm. Nanotechnology makes good use of some ecofriendly nanomaterials with their unique physical, chemical and electrical properties to enhance the activity of B. thuringiensis. The current study focused on the use of Titanate nanotubes (TNT) and Nanosheets (TNS) in pure form and as composites with Bacillus Thuringiensis (Bt), their insecticidal activity and their impacts on different biological features such as; adult longevity, adult sex ratio, pupation, fecundity and percent of eggs hatching were studied. All samples were characterized using Field emission scanning electron microscope (FESEM), X-ray diffraction (XRD), FTIR-spectroscopy and Zetasizer for zeta potential measurements.
