“…For rangeland grasshopper control, Insect Growth Regulators (IGRs) have become popular (Weiland et al 2002). With IGRs, the timing of application is critical to control pest populations, minimize effects on nontarget fauna, and manage cost (Lockwood and Schell 1997Ð1999, Weiland et al 2002 because IGRs are only effective against the immature stages of the insects, and death occurs during molting.…”

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 samples collected over the western two thirds of Nebraska from a 3-yr period and noted the occurrence of adults by region for eight species of rangeland grasshoppers. We analyzed occurrence based on degree-day accumulations for the region and developed estimates of degree-day requirements for these species. Because these grasshopper species are common rangeland pests, degree-day requirements to reach adulthood should improve the effectiveness of grasshopper treatment programs over a large geographic area.

ResumenEl cultivo de amaranto (Amaranthus hypocondriacus L.), se ve afectado por el ataque de insectos plaga; entre las cuales Sphenarium purpurascens Charp, es uno de las principales plagas ocasionado pérdidas importantes, además de generar gastos fuertes en su control químico. Por lo anterior, es necesario contar con alternativas económicas de control que sean inocuas al ambiente y la salud humana. El objetivo de esta investigación fue conocer el efecto de Beauveria bassiana (Balsamo) en combinación con extractos acuosos de chicalote (Argemone mexicana L.), chile (Capsicum frutescens L.) e higuerilla (Ricinus comunis L.) para el control de S. purpurascens en amaranto. Al probar en laboratorio el efecto de B. bassiana sobre S. purpurascens de cinco tratamientos y un testigo (agua) inoculados tópicamente e incubados a temperaturas de 26 ± 1 ºC y HR= 70 ± 10%), a los ocho días después de la inoculación hubo el 100% de mortalidad en el 2º y 4º estadio ninfal con 1.0 X 10 8 y 1.0 X 10 9 conidios mL -1, mientras que en adultos la mortalidad fue de 76 y 81%, respectivamente. En campo se determinó el efecto de extractos de chicalote (Argemone mexicana) + higuerilla (Ricinus comunis) + B. bassiana; extractos de higuerilla + chile (Capsicum frutescens) + B. bassiana; B. bassiana (sin extractos) y testigo (agua) sobre el número de chapulines AbstractThe cultivation of amaranth (Amaranthus hypocondriacus L.), is affected by the attack of insect pests; among which Sphenarium purpurascens Charp, is one of the main pests caused considerable losses and generate heavy spending on its chemical control. Therefore, it is necessary to have economic control alternatives that are harmless to the environment and human health. The objective of this research was to determine the effect of Beauveria bassiana (Balsam) in combination with aqueous extracts of chicalote (Argemone mexicana L.), pepper (Capsicum frutescens L.) and higuerilla (Ricinus comunis L.) for controlling S. purpurascens in amaranth. When testing laboratory the effect of B. bassiana on S. purpurascens five treatments and a control (water) topically inoculated and incubated at temperatures of 26 ± 1 °C and RH= 70 ± 10%), eight days after the inoculation was 100% mortality in the 2 nd and 4 th nymphal stage with 1.0 X 10 8 and 1.0 X 10 9 conidia mL -1 , while adult mortality was 76 and 81%, respectively. Field effect extracts chicalote (Argemone mexicana) + (Ricinus comunis) + B. bassiana was determined; extracts of higuerilla + pepper (Capsicum frutescens) + B. bassiana; B. bassiana (no extracts) and control (water) on the number of live grasshoppers grasshoppers per experimental unit,

“…Since the inception of agriculture, grasshoppers have been one of the most important pests of agriculture in almost every part of the world (Gangwere et al 1997, Weiland et al 2002. During outbreaks, grasshoppers can cause widespread and severe damage to grasslands, forage, cereal, vegetable, and orchard crops (Wright 1986, Pfadt 1994, Olfert and Slinkard 1999, Lockwood et al 2002.…”

We characterized the type and extent of grasshopper injury to above- and below-ground plant parts for four crops [barley (Hordeum vulgare L.), oats (Avena sativa L.), wheat (Triticum aestivum L.), and canola (Brassica campestris L.)] commonly grown, or with potential to grow, in central Alaska. Cages were placed on 48 pots containing plants in second to third leaf stages and stocked with 0, 2, 4, and 6 first-instar Melanoplus sanguinipes F. pot(-1). Plants were harvested 22 d after planting. Stem growth of barley and oats was not affected except at the highest grasshopper treatment. In canola, stem biomass was reduced at the medium and high grasshopper treatments, when most of the leaves had been consumed. The highest grasshopper treatment reduced leaf area in barley and oats by approximately 55%, and caused a significant reduction in dry weight of leaves, stems, and roots (41-72%). Wheat and canola plants were smaller than barley and oats across all treatments and, at the highest grasshopper density, above-ground portions of wheat and canola were completely destroyed. Length and surface area of roots of barley and oats were reduced by 20-28% again at the highest grasshopper density, whereas the reduction for wheat and canola ranged from 50 to 90%. There was little or no difference among all grasshopper densities for C-N ratio in leaf and stem tissues of all crops. The results suggest that wheat and canola are more susceptible than barley and oats and that densities > or = 2 pot(-1) (approximately > or = 50 m(-2)) of even very small grasshoppers could cause significant damage in small-grain and oilseed crop production.
