چکیده
Investigations on the population dynamics of aphid Aphis gossypii Glover Bt (G.Cot.Hy.8 BG II) and non-Bt (G.Cot.Hy.8) were carried out at Main Cotton Research Station, Navsari Agricultural University, Surat, Gujarat during Kharif, 2020-21. The incidence aphids initiated in first week July (27th SW) cotton hybrid second (28th continued till crop harvest January (2nd both hybrids. peak activity was recorded third December (51st as well hybrid. In cotton, had a significant negative correlation with morning relative humidity. There highly minimum temperature, evening humidity, rainfall, rainy days, positive sunshine hours.

Bacterial 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. ...
متن کاملBt proteins Cry1Ah and Cry2Ab do not affect cotton aphid Aphis gossypii and ladybeetle Propylea japonica
Plant varieties expressing the Bt (Bacillus thuringiensis) insecticidal proteins Cry1Ah and Cry2Ab have potential commercialization prospects in China. However, their potential effects on non-target arthropods (NTAs) remain uncharacterized. The cotton aphid Aphis gossypii is a worldwide pest that damages various important crops. The ladybeetle Propylea japonica is a common and abundant natural ...
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 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...
