Abstract
This may be attributed to the facts that nanotechnology has shown an excellent ability to control the release pattern of active ingredients of pesticides, so that it can achieve long-term functions more effectively, thus overcoming the problems of agricultural runoff and residual pesticide accumulation. In addition, Nanopesticides have shown greater solubility and stability of active ingredients, which can effectively control pests (Akhtar et al.,2020). In this study, the insecticidal relative toxicity of carbon nanotubes (CNTs) synthesized from seeds of Iraqi date palm Phoenix dactylifera L. using a chemical vapor deposition (CVD) method was investigated. These Nanoparticles were evaluated against adult and larvae of the Khapra beetle, Trogoderma granarium. The results indicated that CNTs (25, 50 and 100 ppm) caused mortality of the Khapra beetle under laboratory conditions. Additionally, the germination percentage of wheat, Triticum aestivum L. grains, has not been affected by the carbon nanotube treatments at 25-100 ppm. This study demonstrates the potential of CNTs as a technology for population control of T. granarium because of their toxicity to larvae and adults.

Nanotechnology is a term that involving a wide range of technologies dealing with structures and processes at the nanometer scale (Stadler et al, 2018)
This study demonstrates the potential of carbon nanotubes (CNTs) as a technology for population control of T. granarium because of their toxicity to larvae and adults
To the best of our knowledge, this is the first study to report an advantage in using CNTs synthesized from date palm seeds to control T. granarium insects
Summary
Nanotechnology is a term that involving a wide range of technologies dealing with structures and processes at the nanometer scale (Stadler et al, 2018) This principal is employed to enhance the efficacy or reduce the environmental contamination (Sabry & Ragaei, 2018; Al-Rudainy & Khalel, 2019). The use of nanopesticides can reduce the loss of organic solvents and the movement of unwanted pesticides by increasing the dispersion of these formulations (Bergeson, 2010). Technologies such as nanocapsules, nanoemulsions, nanocontainers and nanocages have been reported to provide nanopesticides to protect plants from pests (Bouwmeester et al, 2009; Lyons & Scrinis, 2009)
