Metofluthrin: a potent new synthetic pyrethroid with high vapor activity against mosquitoes.
(1R)-trans-Norchrysanthemic acid fluorobenzyl esters are synthesized and their structure-activity relationships are discussed. These esters show outstanding insecticidal activity against mosquitoes. In particular, the 2,3,5,6-tetrafluoro-4-methoxymethylbenzyl analog (metofluthrin) exhibits the highest potency, being approximately forty times as potent as d-allethrin in a mosquito coil formulati...
متن کاملInsecticidal activity of synthetic amides on Spodoptera frugiperda.
The phytochemistry of the genus Piper (Piperaceae) has been widely studied due to the biological properties of amides from these plants. In this work, we have synthesized and evaluated the toxic effect of 11 amides against the fall armyworm Spodoptera frugiperda larvae. The naturally occurring piperine was also evaluated. The most active amide was N-[3-(3',4'-methylenedioxyphenyl)-2-(E)-propeno...
متن کاملSynthetic pyrethroid insecticides: a dermatological evaluation.
Synthetic pyrethroids are lipophilic insecticides whose biological activity seems to be directly related to their chemical structure. In this investigation differences in cutaneous sensation were detected by human participants between synthetic pyrethroids with a cyano group in the (S)-configuration of the 3-phenoxybenzyl alcohol of their molecular structure (fenvalerate) and those that do not ...
متن کاملPreparation of tetramethylcyclopropanecarboxylic-14C acid and insecticidal terallethrin-14C from it.
Esters of tetramethylcyclopropanecarboxylic acid (I) with (•})-allethrolonel1), (•}) -pyrethrolone2) and some others3) have activity comparable to that of corresponding esters of natural (+)-transchrysanthemic acid against some insect species. However, these esters show differences in toxicity to mammals which are probably resulted from differences in rates or pathways of metabolism. Therefore,...
متن کاملInsecticidal activity of indanomycin.
More than half of the worldwide expenditure on agrochemicals was devoted to insecticides in an effort to combat over half a million different herbivorous insect species1}. Despite this, 15% of the crops planted are lost to feeding insects and other pests2). The cost of this damage and its effect on agriculture has increased the demand for more effective crop protection agents. For manyyears, pe...
