Spinosad is sold under the brand names, Comfortis, Trifexis, and Natroba. [12] [13] Trifexis also includes milbemycin oxime. Comfortis and Trifexis brands treat adult fleas on pets; the latter also prevents heartworm disease. [14] Natroba is sold for treatment of human head lice. [15] Spinosad is also commonly used to kill thrips. [16]
Spinosad does not kill on contact and must be ingested by the leaf miner. Two or three applications may be required in a season. However, this will have harmful ecological effects, especially if sprayed when bees or other beneficial arthropods are present.
Imidacloprid is a systemic insecticide belonging to a class of chemicals called the neonicotinoids which act on the central nervous system of insects. The chemical works by interfering with the transmission of stimuli in the insect nervous system. Specifically, it causes a blockage of the nicotinergic neuronal pathway.
Out of 32 conventional and 11 biological insecticides, the researchers found a handful that killed or restricted feeding. The conventional insecticides have technical names, such as spinosad and ...
Spinosad is a new chemical class of insecticides derived from a soil dwelling bacterium discovered in 1982. It is considered practically non-toxic to humans, pets, and beneficial insects. Unlike other insecticides, Spinosad will not harm beneficial insects including the Amber Marked Leafminer parasite.
Because of their insecticide and insect repellent effect, pyrethrins have been very successful in reducing insect pest populations that affect humans, crops, livestock, and pets, such as ants, spiders, and lice, as well as potentially disease-carrying mosquitoes, fleas, and ticks.
Pyrethroids are much less toxic in mammals than they are in insects and fish, because mammals have the ability to rapidly break the ester bond in bifenthrin and break the substance into its inactive acid and alcohol components. [2] In humans and rats, bifenthrin is degraded by the cytochrome p450-family. [5]
Fipronil is a broad-spectrum insecticide that belongs to the phenylpyrazole insecticide class. [3] Fipronil disrupts the insect central nervous system by blocking the ligand-gated ion channel of the GABA A receptor (IRAC group 2B) and glutamate-gated chloride (GluCl) channels.
