This study describes the insecticidal activity of a novel Bacillus thuringiensis Cry-related protein with a deduced 799 amino acid sequence (~89 kDa) and ~19% pairwise identity to the 95-kDa-aphidicidal protein (sequence number 204) from patent US 8318900 and ~40% pairwise identity to the cancer cell killing Cry proteins (parasporins Cry41Ab1 and Cry41Aa1), respectively. This novel Cry-related ...

Abstract Conservation biological control could be an alternative to insecticides for the management of aphid Myzus persicae (Sulzer). To develop sustainable strategies M. in peach orchards Mediterranean, a 2-yr field experiment was conducted identify key predators aphid; determine whether proximity insectary plants boost natural enemies comparison resident vegetation; and selected enhance enemy...

The phloem provides a unique niche for several organisms. Aphids are a large group of Hemipteran insects that utilize stylets present in their mouthparts to pierce sieve elements and drink large volumes of phloem sap. In addition, many aphids also vector viral diseases. Myzus persicae, commonly known as the green peach aphid (GPA), is an important pest of a large variety of plants that includes...

Single-molecule magnets (SMMs) present a promising avenue to develop spintronic technologies. Addressing individual molecules with electrical leads in SMM-based spintronic devices remains a ubiquitous challenge: interactions with metallic electrodes can drastically modify the SMM's properties by charge transfer or through changes in the molecular structure. Here, we probe electrical transport t...

Plant viruses, and aphids as their vectors, are limiting factors in sugar beet production. Viral plant diseases currently impossible to treat but knowing the flight patterns of can help reducing number potential virus vectors. Monitoring aphid activities fields was done using yellow water traps from April end November. During two years investigation, a total 5514 specimens 75 different taxa wer...

This work includes, identification eight species of Aphids (Homoptera: Aphididae) which collected from the leaves different plants in many localities Erbil governorate Kurdistan region-Iraq period May till July 2022, these are: Chaitophorus salijaponicus, Aphis fabae, Macrosiphum rosae, Capitophorus carduinus, Myzus persicae, ruborum, punca, and gossypii. The mitochondrial cytochrome C Oxidase ...

We previously described a novel densovirus [Myzus persicae nicotianae densovirus (MpnDV)] infecting M. persicae nicotianae (Hemiptera: Aphididae) with 34% prevalence. This single-stranded DNA virus has a 5480-nucleotide ambisense genome and belongs to the Densovirinae subfamily within the family Parvoviridae. In the present study, we estimated the genetic diversity of MpnDV using partial nonstr...
