Quantification of the Pirimicarb Resistance Allele Frequency in Pooled Cotton Aphid (Aphis gossypii Glover) Samples by TaqMan SNP Genotyping Assay
BACKGROUND Pesticide resistance monitoring is a crucial part to achieving sustainable integrated pest management (IPM) in agricultural production systems. Monitoring of resistance in arthropod populations is initially performed by bioassay, a method that detects a phenotypic response to pesticides. Molecular diagnostic assays, offering speed and cost improvements, can be developed when the caus...
متن کاملlethal and sublethal effects of imidacloprid and pirimicarb on the melon aphid, aphis gossypii glover (hemiptera: aphididae) under laboratory conditions
the toxicity of imidacloprid and pirimicarb for all stages of the melon aphid, aphis gossypii glover, were investigated under laboratory conditions (25 ± 1 oc, 65 ± 5% r.h. and a photoperiod of 16:8 (l: d) h.) using a leaf dipping method. these pesticides were very toxic for first instar nymphs of a. gossypii with lc50 values of 17 and 220.2 ppm for imidacloprid and pirimicarb, respectively. fo...
متن کاملpopulation density and spatial distribution of aphis gossypii glover (homoptera: aphididae) on cotton in gorgan, iran
the seasonal abundance patterns of the cotton aphid, aphis gossypii glover, in cotton fields at gorgan in northern iran were studied during two growing seasons of 2002 and 2003. the spatial distribution of different developmental stages and morphs of the aphid was described by fitting data to poisson (random) and negative binomial (aggregated) dis-tributions, and calculating the dispersion indi...
متن کاملINSECTICIDE RESISTANCE IN THE COTTON APHID, Aphis gossypii GLOVER IN EGYPT
The cotton aphid, Aphis gossypii Glover (Hemiptera Aphididae), is one of the most important sap sucking pests in many cotton-growing areas world-wide. In this study, the efficacies of seven insecticides [organophosphate (Fenitrothion & Pirimiphos-methyl), carbamate (Carbosulfan & Aldicarb), pyrethroid (Lambda-Cyhalothrin & Deltamethrin) and imidaclopride (Confidor)] were determined against four...
متن کاملRelationship between Aphis gossypii (Homoptera: Aphididae) and sticky lint in cotton.
The study was conducted in the northern Texas Rolling Plains in 1999 to define the relationship between number of cotton aphids, Aphis gossypii Glover, and resulting contamination of cotton lint by honeydew. Whole-plot treatments were three furrow irrigation management treatments: cotton grown without supplemental irrigation (dryland), irrigated cotton with last irrigation in mid August, and ir...
