Ptomaphaginus Portevin, 1914 is one of the most speciose genera in the tribe Ptomaphagini (Coleoptera: Leiodidae: Cholevinae). Its members are mainly soil dwellers and are almost all distributed in the Oriental Region. This paper reports eleven new species from China: P. guangxiensis sp. nov. (type locality: Napo, Guangxi autonomous region), P. gutianshanicus sp. nov. (type locality: Gutianshan...

New species are described in Cerambycinae, in Elaphidiini: Eurystheaparva sp. nov. from Ecuador (Loja); in Hexoplonini: Hexoplon rubriceps sp. nov. from Ecuador (Napo); in Neoibidionini: Cycnidolon praecipuum sp. nov. from Bolivia (Santa Cruz); in Pteroplatini: Pteroplatus caudatus sp. nov. from Colombia (Cundinamarca); Pteroplatus pallidicolor sp. nov. from Peru (Cajamarca); in Tillomorphini: ...

Plastic reflective mulches significantly reduced populations of corn leafhopper, Dalbulus maidis (DeLong & Wolcott), adults and the incidence of corn stunt disease caused by Spiroplasma kunkelii (CSS) in late planted sweet corn (Zea mays L.). The reflective mulches were more effective than were either foliar or soil applied insecticides in managing both the leafhopper and the pathogen it transm...

The cotton intercropping experiment was conducted for the management of sucking pests, viz. leafhopper, Amrasca biguttula Ishida (Hemiptera: Cicadellidae); whitefly, Bemisia tabaci Gennadius Aleyrodidae) and thrips, Thrips Linderman (Thysanoptera: Thripidae) in desi cotton, Gossypium arborium. results study revealed that less mean population leafhopper nymphs, whitefly thrips adults recorded fr...

A new genus of tribe Erythroneurini from China, Laciniata gen. nov. is described and illustrated based on type species L. lijianga sp. nov.

a faunistic survey was conducted to identify the leafhoppers in the southwest of iran (khouzestan province) in 2014. among the collected materials, aconurella nuristana dlabola, 1957 is recorded for the first time for iranian leafhoppers fauna. diagnostic characters and geographical distribution of the newly recorded species is presented briefly.

The potato leafhopper (PLH) is the most serious insect pest of alfalfa in Wisconsin and the Upper Midwest. PLH injury to alfalfa can result in leaf yellowing (“hopperburn”), plant stunting, loss of yield and forage quality, and reduced alfalfa stand persistence. Leafhopper populations are a perennial problem in new alfalfa seedings, and they frequently increase to damaging levels on the second ...

The effect of irrigation on the abundance of Empoasca vitis (Göthe) populations was investigated in four vineyards located in northeastern Italy. In two experiments, we compared leafhopper population densities in plots irrigated (micro-spray irrigation system) or nonirrigated. In another experiment, we studied the effect of various irrigation systems on E. vitis populations over two successive ...
