Diflubenzuron is an insecticide of the benzoylurea class. [2] It is used in forest management and on field crops [ 3 ] to selectively control insect pests, particularly forest tent caterpillar moths , boll weevils , gypsy moths , and other types of moths . [ 1 ]
The insecticidal activity of the BPUs was discovered serendipitiously at Phillips-Duphar who commericalised diflubenzuron in 1975. [1] Since then, many BPUs were commercialised by many companies. BPUs accounted for 3% of the $ 18.4 billion world insecticide market in 2018. [3] Lufenuron, was the largest selling BPU in 2016, selling for $ 112 ...
Insect growth regulator (IGR) is a term coined to include insect hormone mimics and an earlier class of chemicals, the benzoylphenyl ureas, which inhibit chitin (exoskeleton) biosynthesis in insects [42] Diflubenzuron is a member of the latter class, used primarily to control caterpillars that are pests.
Novaluron, or (±)-1-[3-chloro-4-(1,1,2-trifluoro-2-trifluoro- methoxyethoxy)phenyl]-3-(2,6-difluorobenzoyl)urea, is a chemical with pesticide properties, belonging to the class of insecticides called insect growth regulators.
Research on botanical oils has found neem oil to be larvicidal. [citation needed] Larvicidal activity of neem oil (Azadirachta indica) formulation against mosquitoes. Median lethal concentration (LC50) of the formulation against Anopheles stephensi, Culex quinquefasciatus and Aedes aegypti was found to be 1.6, 1.8 and 1.7 ppm respectively.
Vigilante is an insecticide used with both dairy and beef cattle to reduce the number of flies in an agricultural area. It is usually formatted as a 50-gram bolus containing 9.7% diflubenzuron, [1] an insect growth regulator which inhibits the formation of chitin and prevents insects from reproducing. [2]
The acylurea functional group is also found in some pharmaceutical drugs such as the anticonvulsants phenacemide, pheneturide, chlorphenacemide, and acetylpheneturide (which are phenylureides), [3] and the sedatives acecarbromal, bromisoval, and carbromal (which are bromoureides).
Ovicidal IGIs, such as diflubenzuron, hexaflumuron and teflubenzuron, have been shown to be effective against egg development. Fenoxycarb is an ovicidal IGR, while Tebufenozide is a larvicidal IGR. Flufenoxuron and Methoxyfenozide are an IGI and IGR respectively and are equally effective in preventing growth in eggs as in larvae. [ 29 ]
