Influence of different synergists on the toxicity of some insecticides to susceptible and resistant larvae of Spodoptera littoralis (Boisd.). Riskallah, Medhat R. (Inst. Plant Prot., Agric. Res. Cent., Dokki, Egypt). Indian J. Agric. Sci., 54(2), 126-30 (English) 1984. CODEN: IJASA3. ISSN: 0019-5022. DOCUMENT TYPE: Journal CA Section: 5 (Agrochemical Bioregulators) In a susceptible strain of S. littoralis, , antagonism was obsd. with all the tested synergists when mixed with aminocarb [2032-59-9], leptophos [21609-90-5], and chlorpyriphos [2921-88-2].There are some commonly used reagents with their cas registry numbers 70124-77-5 and 94-59-7 in this article. With fenvalerate [51630-58-1] and cybolt [70124-77-5], a slight synergism was achieved when combined with sulfoxide [120-62-7], MGK 264 [113-48-4], piperonyl butoxide [51-03-6], safrol [94-59-7], and isosafrol [120-58-1], whereas antagonism occurred with DEF [78-48-8]. In the resistant strains, higher degrees of synergism were brought about with all the insecticide-synergist combinations. Aminocarb was highly synergized with safrol, isosafrol, and DEF. With respect to fenvalerate and cybolt, piperonyl butoxide and DEF showed the best results. .

Michael (Beckman Instrum., Inc.In this study， 134-62-3 and 5281-13-0 are also used., Berkeley, CA 94710, USA). LC, Liq. Chromatogr. HPLC Mag., 1(9), 566-7 (English) 1983. CODEN: LCHMD7. ISSN: 0746-0252. DOCUMENT TYPE: Journal CA Section: 59 (Air Pollution and Industrial Hygiene) Section cross-reference(s): 5, 80 Three insecticide synergists (i.e. piperonyl butoxide (I) [51-03-6], octylbicycloheptenedicarboximide [113-48-4], piprotal [5281-13-0]) and 1 insect repellent (DEFT [134-62-3]) were sepd. by reversed-phase high-performance liq. chromatog. (HPLC) in a scheme that did not exhibit interference from the insecticides. Residues from personal monitor badges collected from a house sprayed with a com. insecticide bomb were extd. with MeCN, concd. in modified Kuderna-Danish concentrators, dild. with MeCN, and analyzed. Duplication recovery expts. at 75 pg and 100 pg indicated 98-104% recovery of samples. No interferences from synthetic pyrethroids were noted in the air samples, and fortified air samples showed 99.1% recovery (mean of 3 samples with 75 pg added). The calcd. limit of detection for I was 46 pg, with a decision limit (lowest level detectable above noise) of 22 pg. .
