Polyacrylamide gel electrophoresis system (PAGE) and inhibition tests for biochemical characterization of alpha- beta-esterases were used to obtain a functional classification esterases fromAspidosperma polyneuron. The from young leaves A. polyneuron by the PAGE showed fourteen esterase isozymes. differential staining pattern that Est-2 isozyme hydrolyzes beta-naphthyl acetate; Est-6, Est-7 Est-8 isozymes hydrolyze alpha-naphthyl acetate, Est-1, Est-3, Est-4, Est-5, Est-9, Est-10, Est-11,...
The brown stink bug Euschistus heros is the most abundant species of soybean-sucking bugs, and causes large economic losses.Applying different chemical groups organosynthetic insecticides for its control increases potential resistance.Esterases are a group enzymes that play variety roles in insects, some them related to metabolism xenobiotics.The aim this study was analyze esterase isoenzyme system investigate response Engeo ™ Pleno (thiamethoxam lambda-cyhalothrin), which widely used...
Oryzaephilus mercator and O. surinamensis are stored grains processed food pests, the latter being responsible for major economical losses. Polyacrylamide gel electrophoresis was used to analyse esterase patterns during insect development. Seven esterases, three cholinesterases, two carboxylesterases acetylesterases, were identified in mercator, one of which proper adults. Five four occurred surinamensis. Strains also exposed malathion chlorpyrifos-methyl. According LC50 estimates, OmLC-M...
Abstract Lasioderma serricorne (F.) is a small cosmopolitan beetle regarded as destructive pest of several stored products such grains, flour, spices, dried fruit and tobacco. Chemical insecticides are one the measures used against pest. However, intensive insecticide use has resulted in appearance resistant insect populations. Therefore, for elaboration more effective control programs, it necessary to know biological aspects L. serricorne. Among these aspects, genetic variability knowledge...
Allozyme electrophoresis analysis were performed in four species of Hypostomus (Loricariidae), H. albopunctatus, hermanni, regani, e sp. 1/NUP 5612 from the Ivaí river, a tributary upper Paraná river. The study 14 loci revealed diagnostic characters and exclusive alleles low frequency. heterozygosity ranged 0.000 albopunctatus to 0.199 which was higher than other samples literature, as well fish groups. regani similarity (I = 0.804), while hermanni showed least genetic identity 0.569). All...
Current analysis characterizes the effect of different fungicides often applied for pest control on a-and b-esterase patterns four economically important table-wine grape cultivars (Italia, Rubi, Benitaka and Brasil) Vitis vinifera. The a- in bud leaves were assessed by native PAGE analysis. Cabrio Top® compound inhibited Est-2, Est-5, Est-6, Est-7, Est-8, Est-9 Est-10 carboxylesterases, whereas Est-4, Est-11, Est-12, Est-13, Est-14 acetylesterases Est-16 carboxylesterase detected as weakly...
