Virulence of commercial strains entomopathogenic nematode (EPN) Steinernema carpocapsae (Weiser), feltiae Filipjev and Heterorhabditis bacteriophora Poinar (Rhabditida: Steinernematidae, Heterorhabditidae), were tested on young females Pulvinaria hydrangeae Steinweden, Partenolecanium corni (Bouché) Coccus pseudomagnoliarum (Kuwana) (Hemiptera, Coccidae) a native strain H. was citricola scale, ...

Scale insects (Hemiptera: Coccoidae) constitute a very diverse group of sap-feeding insects with a large diversity of symbiotic associations with bacteria. Here, we present the complete genome sequence, metabolic reconstruction, and comparative genomics of the flavobacterial endosymbiont of the giant scale insect Llaveia axin axin. The gene repertoire of its 309,299 bp genome was similar to tha...

Scale insects (Hemiptera: Coccoidea) are small herbivorous insects found on all continents except Antarctica. They are extremely invasive, and many species are serious agricultural pests. They are also emerging models for studies of the evolution of genetic systems, endosymbiosis and plant-insect interactions. ScaleNet was launched in 1995 to provide insect identifiers, pest managers, insect sy...

The adult female and first-instar nymph of a new species of iceryine scale insect, Crypticerya multicicatrices Kondo & Unruh sp. n., are described and illustrated. The new scale insect is polyphagous and was collected on 13 plant species distributed in seven botanical families, including fruit trees of economic importance such as mango and soursop. A taxonomic key to the species of the tribe Ic...

Soil nutrient availability, invasive plants, and insect presence can directly alter ecosystem structure and function, but less is known about how these factors may interact. In this 6-year study in an old-field ecosystem, we manipulated insect abundance (reduced and control), the propagule pressure of an invasive nitrogen-fixing plant (propagules added and control), and soil nutrient availabili...
