“…To determine whether other metabolites of aldrin and dieldrin were present, some of the fat samples were also analyzed for total organically bound chlorine. The combustion method described by Hudy and Dunn (5) was used for the analyses. The samples were saponified and extracted with n-hexane.…”

malathion had a slight effect at 100 p.p.rn. on both plasma and red cell cholinesterase, whereas, a purified sample was reported to have produced no significant inhibition when fed at the same dietary concentration.Pertinent to these findings, Plapp and Casida (20) have postulated a metabolic pathway for ronnel in mammals. Two primary sites of hydrolytic attack were reported. Part of the molecule is believed to split with the formation of dimethylphosphorothioic acid, but to a greater extent the phosphorus-oxygenmethvl linkage is hydrolyzed, yielding stable O-me thyl-O-hydrogen-0-(2,4,5-trichlorophenyl) phosphorothioate. These primary metabolites are excreted rapidly by the rat via urine. The metabolic pathway in a cow is believed similar to that postulated for rats, but with a slower rate of detoxication and excretion. This pattern of metabolism indicates no appreciable conversion /' ronnel, in vivo, to the oxygen analog as it is commonly associated with certain other organic phosphate insecticides.Experience in the therapeutic use of ronnel on cattle for grub control and the work on metabolism of Plapp and Casida (20) indicate that ronnel is absorbed rapidly into the blood stream upon oral administration and that its degradation products are readily excreted.

“…Structural uniqueness gives marine natural products an advantage in insecticide development. Currently, many highly effective commercial insecticide products are dominated by chemically synthesized halides, sulfides, and nitrides [20–24] . A large number of marine natural products have these elements themselves, which is rare in land natural products [25–29] .…”

Due to the unique environmental conditions and vast territory, marine habitat breeds more abundant biological resources than terrestrial environment. Massive marine biological species provide valuable resources for obtaining a large number of natural products with diverse structure and excellent activity. In recent years, new breakthroughs have been made in the application of marine natural products in drug development. In addition, the use of marine natural products to develop insecticides and other pesticide products has also been widely concerned. Targeting marine plants, animals, and microorganisms, we have collected information on marine natural products with insecticidal activity for nearly decade, including alkaloids, terpenes, flavonoids and phenols fatty acids, peptides, and proteins, et al. In addition, some active crude extracts are also included. This review describes the insecticidal activities of marine natural products and their broad applications for future research in agriculture and health.
