Pesticides are typically used in agriculture or public health programmes to protect plants from pests, weeds, and diseases, as well as to protect humans from vector-borne diseases such as malaria, dengue fever, and schistosomiasis. Residues of pesticides can be found in a variety of common foods and beverages, including prepared meals, water, wine, fruit juices, snacks, and animal feeds. It's also worth noting that washing and peeling won't totally eliminate the residues. Deltamethrin belongs to the pyrethroid family of insecticides. Pyrethroids are synthetic counterparts of pyrethrins, which are naturally occurring insecticides found in chrysanthemum flowers. Deltamethrin assaults the CNS (central nervous system) of any animal upon contact with even for a short period of time. Model organism silkworm is used for studying the toxicity effect of pesticides in-vivo. Silkworms are a promising model animal for health safety and environmental pollution assessment due to their sensitivity to chemical compounds such as pesticides, drugs, and heavy metals, as well as their low cost, body characteristics, and complete genome sequencing.
