The insertion of irrigated perimeters and the intensive use pesticides made Baixo Jaguaribe region one most critical areas agribusiness in Ceará. However, excessive has been associated with increased cases premature births, congenital malformations mainly neoplasms, especially penile cancer. Objective: To characterize silico triazine group used Jaguaribe-Apodi Irrigated Perimeter to investigate...

A highly sensitive method was developed for the determination of the residues of cyromazine (CYR) and its metabolite, melamine (MEL), in herbal and edible plant samples by using reversed phase high-performance liquid chromatography-diode-array detection (RP-HPLC-DAD) with accelerated solvent extraction and solid phase extraction cleanup. The conditions of separation and detection were investiga...

To clarify the reason for the recent dramatic outbreak of the leafminer, Chromatomyia horticola (Goureau), on the green pea in Japan, the insecticide susceptibility of two leafminer populations collected from grower’s pea fields in Shizuoka and Kagoshima Prefectures was measured in a laboratory assay. Of the five insecticides registered for leafminer control on the pea, cartap was moderately ef...

An indirect competitive enzyme-linked immunosorbent assay (icELISA) with enhanced specificity for melamine in milk was developed. Three haptens of melamine with different spacer-arms were used to prepare different plate coating antigens. It was found that the icELISA show best sensitivity and specificity to melamine when using the coating antigen prepared by coupling 3-(4,6-diamino-1,6-dihydro-...

Atrazine molecular imprinted polymers (MIPs) were comparatively synthesized using identical polymer formulation by far-infrared (FIR) radiation and ultraviolet (UV)-induced polymerization, respectively. Equilibrium binding experiments were carried out with the prepared MIPs; the results showed that MIP(uv) possessed specific binding to atrazine compared with their MIP(FIR) radiation counterpart...

Abstract Drosophila suzukii (Diptera: Drosophilidae) is an invasive species that causes great damages to many stone and small fruits, resulting in reduced fruit production high economic losses. The concern about this pest has led the research of a wide range possible control methods. However, main strategies are still based insecticide applications. efficacy different insect growth regulators (...
