چکیده

predatory damsel bug, nabis pseudoferus remane has a high density in the alfalfa fields and feeds on different types of prey. in this study, biological properties and life table statistics of n. pseudoferus by feeding on melon aphids have been determined under controlled conditions (at 25±1˚c, 60±10% relative humidity and under a photoperiod of 16h light/ 8h dark). data analysis carried out based on age-stage two sex life table program. the results indicated that the mean duration of eggs, 1st instar, 2nd instar, 3rd instar, 4th instar, 5th instar nymphs and adult longevity was 9.00±0.05, 2.89±0.02, 2.86±0.02, 3.10±0.03, 3.67±0.03, 5.87±0.05 and 19.47±0.52, days respectively. life table statistics include r, r0, grr, λ and t were estimated as 0.06±0.002 day-1, 16.39±1.99 eggs/individual, 59.58±6.16 eggs/individual, 1.07±0.002 day-1 and 43.97±0.31days, respectively. the death and birth rates for this predator by feeding on melon aphid were determined 0.02 and 0.08, respectively. with regard to predatory habit of most life stages of n. pseudoferus and longevity of adults, this predator could be considered as a potential candidate for reducing cotton aphid populations.

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. ...

Bottom-up Effect of Two Host Plants on Life Table Parameters of Aphis gossypii (Hemiptera: Aphididae)

Aphis gossypii Glover is one of the most important pests of greenhouse cucumber and pepper in the world and Iran. In this research, life table and biology of A. gossypii were investigated on cucumber (Cucumis sativus cv. Super Sultan) and pepper (Capsicum annum cv. Marqueza) in a growth chamber at 25±1°C and 60±5% RH and a photoperiod of 14 L: 10 D hour. The results showed that developmental ti...

Bt 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 ...

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...

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...
