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 ]
Chemical structure of diflubenzuron, a commonly used benzoylurea insecticide. Benzoylureas (BPUs) are chemical derivatives of N-benzoyl-N ′-phenylurea, which are used as insecticides. [1] They do not directly kill the insect, but disrupt moulting and egg hatch, and thus act as insect growth regulators.
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.
Bioactivity of novaluron is usually much greater than that of insecticides diflubenzuron and teflubenzuron and the compound is at least as active as other insecticides from its developmental generation, for example chlorofluazuron and lufenuron. [11]
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]
Flufenoxuron is an insecticide that belongs to the benzoylurea chitin synthesis inhibitor group, which also includes diflubenzuron, triflumuron, and lufenuron. [1] Flufenoxuron is a white crystalline powder. It is insoluble in water, is not flammable, and is not an oxidizer.
ATCvet code QP53 Ectoparasiticides, including insecticides and repellents is a therapeutic subgroup of the Anatomical Therapeutic Chemical Classification System for veterinary medicinal products, a system of alphanumeric codes developed by the World Health Organization (WHO) for the classification of drugs and other medical products for veterinary use.
The most commonly used chemical pesticides currently registered by the US Environmental Protection Agency (EPA) for use against the gypsy moth contain carbaryl, diflubenzuron, or acephate. Malathion, methoxychlor, phosmet, trichlorfon, and synthetic pyrethroids are registered by EPA but are used infrequently.
