Immersion Tolerance in Rangeland Grasshoppers (Orthoptera: Acrididae)

Grasshopper (Orthoptera: Acrididae) Community Composition in the Rangeland of the Northern Slopes of the Qilian Mountains in Northwestern China

In order to describe grasshopper (Orthoptera: Acrididae) species composition, diversity, abundance, and density of four rangelands types, we compared the grasshopper community composition and dynamics in the rangeland of the northern slopes of the Qilian Mountains. In total, 55 grasshopper species were collected from 2007 to 2009, representing three families and six subfamilies. The subfamily O...

Degree-day requirements for eight economically important grasshoppers (Orthoptera: Acrididae) in Nebraska using field data.

The timing of application for the management of rangeland grasshoppers (Orthoptera: Acrididae) is critical, especially as insecticides become more specialized and the use of Insect Growth Regulators becomes more widespread. The general seasonal occurrence of adults of many grasshopper species has been well documented; however, their appearance varies widely between years. We analyzed sweep samp...

Studies in Guatemalan Caelifera: New grasshoppers and monkey grasshoppers (Orthoptera: Caelifera: Acridoidea & Eumastacoidea) and an updated checklist.

We describe six species of Acridomorpha, Orthoptera from Guatemala: Paralethus rowelli n. sp., Paralethus cerezoi n. sp., Episactus schusteri n. sp. (Episactidae: Episactinae), Pararhicnoderma eniocanoi n. sp. (Romaleidae: Bactrophorinae), Tela neumanni n. sp. and Leioscapheus faustinoi n. sp. (Acrididae: Proctolabinae). four genera and five species are recorded for Guatemala and, at the same t...

Susceptibility to Disease Across Developmental Stages: Examining the Effects of an Entomopathogen on a Grasshopper (Orthoptera: Acrididae) Pest

New Record of Grasshopper (orthoptera: Acrididae & Romaleidae) Defoliators and Population Dynamics of Insects on Crops of Heliconia Spp. in the Amazon

Despite the expansion of floriculture, little is known about insects associated to this crop in northern Brazil. The objective was to identify the main species of defoliator grasshoppers, associated to crops of Heliconia spp. in the northeastern region of State of Pará, Brazil , in the municipalities of Castanhal, Belém and Benevides, from Aug 2004 to Mar 2005. Representatives with higher abund...
