Insecticidal Effects of Activated Charcoal and Clays

Nature, 1959
BRISCOE1, Kitchner et al. 2, Wigglesworth3, and Parkin4 have studied the ‘inert’ dusts for their insecticidal action. Reports on the insecticidal properties of ‘inert’ dusts, particularly of silica, coal ash, diamond, ‘Carborundum’, dusts from blast furnaces, flint, felspar, magnesite and dolomite are available1,2,4.

Ribavirin, a nucleoside with potential insecticidal activity

Pest Management Science, 2012
AbstractBACKGROUND: The triazole‐based antiviral nucleoside ribavirin exhibited significant in vitro insecticidal effects against Spodoptera litura, a finding that has prompted further investigations into its in vivo insecticidal properties and mode of action against this insect pest.RESULTS: Ribavirin showed delayed insecticidal effects on third ...

Synthesis and insecticidal activity of new pyrethroids

Pest Management Science, 2009
AbstractBACKGROUND: Pyrethroids are among the most potent pesticides known, with great potential for structural variation with retention or enhancement of potency. The simple methyl ester is easier to prepare (at least one step shorter) than the more complex pyrethroids modified on the alcohol moiety.

Estrogenic and Antiprogestagenic Activities of Pyrethroid Insecticides

Biochemical and Biophysical Research Communications, 1998
Many pesticides possess hormonal activity and have thus been classified as endocrine disruptors. Pyrethroids are commonly used insecticides worldwide, but little has been done to characterize their hormone agonist/antagonist potential. We tested four frequently encountered pyrethroids, fenvalerate, sumithrin, d-trans allethrin, and permethrin, for ...

Insecticidal activity of novel thioureas and isothioureas

Pest Management Science, 2016
AbstractBACKGROUNDWe hypothesized that the exploration of chemical space around compounds with reported insecticidal activity could be a viable strategy for discovering novel, insecticidally active areas of chemistry.RESULTSA series of thioureas and isothioureas were prepared as part of a scaffold‐hopping effort around known insecticidal compounds ...

Insecticidal activity of certain medicinal plants

Fitoterapia, 2004
The methanol extracts of eight species of medicinal plants were tested for insecticidal activity in third instar larvae of Egyptian cottonworm (Spodoptera littoralis). All extracts showed a certain degree of larval toxicity. The extracts of Ocimum basilicum, Origanum majorana and Salvia officinalis appeared to be highly toxic.
