title: Assessment of two natural marine toxins (Microcystis aeruginosa and Parasicyonis actinostoloides) for the control of some medical and agriculture insects with reference to the action on mice.
abstract: The present work describes the insecticidal potentiality from Microcystis aeruginosa (cyanobacteria) and Parasicyonis actinostoloides (Sea anemone) water extracts against 3rd larval instar of medical insects (Musca domestica and Culex pipiens) and 4th larval instar of agriculture insects (Spodoptera littoralis and Agrotis ipsilon. The LD50s of M. aeruginosa extract were 1.94, 2.33, 7.59 and 9.10 mg/ml. for M. domestica, C. pipiens, S. littoralis and A. ipsilon). respectively. While LD50s of P. actinostoloides extract were 19.28, 24.7, 27.3 and (29.4) mg/ml. for M. domestica, C. pipiens, S. littoralis, and A. ipsilon respectively. The aqueous extracts of M. aeruginosa and P. actinostoloides had no acute or chronic marked effect on mice as serum acetyl cholinesterase and gave more or less nearly the same level of AchE activity at the end of decapitation periods.
