RAPID ENZYME IMMUNOASSAYS FOR THE DETECTION OF CARBARYL AND METHOPRENE IN GRAINS

Journal of Environmental Science and Health, Part B, 2002
In order for grain handlers and traders to reliably estimate residues of grain protectants in the field, antibody-based rapid tests were developed for carbaryl (1-naphthyl methylcarbamate) and methoprene [isopropyl (E,E)-(RS)-11-methoxy-3,7,11-trimethyldodeca-2,4-dienoate].

Synthesis of methoprene via electroreduction of the thiophene ring

Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 1983
The synthesis of the juvenoid methoprene and its 2Z,4E isomer (as a ∼1∶1 mixture) has been accomplished, one of the steps being the electrochemical reduction of a 3,5-dialkylthiophene-2-carboxylic acid.

Environmental degradation of the insect growth regulator methoprene

Pesticide Biochemistry and Physiology, 1975
Abstract The metabolism of methoprene ( I , isopropyl ( 2E,4E )-11-methoxy-3,7,11-trimethyl-2,4-dodecadienoate, trademark Altosid) was investigated in larval mosquitoes and houseflies. The most abundant primary metabolite in third- and fourth-instar Aedes and fourth-instar Culex larvae was the hydroxy ester while the hydroxy acid predominated in ...

Validation of an enzyme immunoassay for analysis of methoprene residues on tobacco

Journal of Agricultural and Food Chemistry, 1992
Methoprene [isopropyl 11-methoxy-3,7,11-trimethyl-2(E),4(E)-dodecadienoate] is a synthetic insect growth regulator that is used extensively for control of the cigarette beetle(Lasioderma serricorne) in stored grins and tobacco products. In 1990 a successful cELISA was developed for methoprene; more recently, this immunoassay was redeveloped as an ...

Sterilising activity of methoprene and hydroprene inTribolium castaneum (Herbst)

Experientia, 1978
The productivity ofT. castaneum adults, previously reared in flour incorporating either the IGR methoprene or hydroprene, was found to be impaired depending on the concentration of the IGR in the flour, whether or not the individual was morphologically deformed, and its sex.
