INSECTICIDE 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 کاملThe joint action of destruxins and botanical insecticides (rotenone, azadirachtin and paeonolum) against the cotton aphid, Aphis gossypii Glover.
The joint action of destruxins and three botanical insecticides, rotenone (Rot), azadirachtin (Aza) and paeonolum (Pae) against the cotton aphid, Aphis gossypii, was bioassayed. In laboratory experiment, several synergistic groups of destruxins with botanical insecticides were found by means of Sun's Co-toxicity Coefficients (CTC) and Finney's Synergistic Coefficient (SC). The best synergistic ...
متن کاملQuantification 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 کاملInfluences of fertilization on Aphis gossypii and insecticide usage
Fertilization levels for ornamental crops may influence pest population dynamics, crop quality, and pest management strategy. We examined the effect of fertilization on population growth and within-plant distribution of melon or cotton aphid, Aphis gossypiiGlover, on potted chrysanthemum, Dendranthema grandiflora (Tzvelev). In terms of pest management implications, we also investigated the effe...
متن کاملBacterial communities of the cotton aphid Aphis gossypii associated with Bt cotton in northern China.
Aphids are infected with a wide variety of endosymbionts that can confer ecologically relevant traits. However, the bacterial communities of most aphid species are still poorly characterized. This study investigated the bacterial diversity of the cotton aphid Aphis gossypii associated with Bt cotton in northern China by targeting the V4 region of the 16S rDNA using the Illumina MiSeq platform. ...
