Ribavirin, a nucleoside with potential insecticidal activity
Pest Management Science, 2012AbstractBACKGROUND: 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 ...

Estrogenic and Antiprogestagenic Activities of Pyrethroid Insecticides
Biochemical and Biophysical Research Communications, 1998Many 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, 2016AbstractBACKGROUNDWe 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 ...

Modulation of a lectin insecticidal activity by carbohydrates
Archives of Insect Biochemistry and Physiology, 2000Lectins from plants present an insecticidal activity most probably through their carbohydrate binding properties; as a consequence, their toxicity should vary with the presence of a competitive sugar in the ingested food. In order to test this hypothesis, we performed competition experiments between insecticidal activity and carbohydrate binding.

A series of new pymetrozine analogues containing both methyl on the imine carbon and phenoxy group at the pyridine ring were designed and synthesized. Their insecticidal activities against bean aphid (Aphis craccivora), mosquito larvae (Culex pipiens pallens), cotton bollworm (Helicoverpa armigera), corn borer (Ostrinia nubilalis) and oriental armyworm

AbstractThe electrophysiological actions of various neonicotinoids, including substituted benzyl derivatives, against recombinant Drosophila SAD/chicken β2 hybrid nicotinic acetylcholine receptor (nAChR) were measured to analyze the relationships between the in vivo (insecticidal) and in vitro (binding and agonist) activities.
