The grasshopper Sphenarium purpurascens Charpentier (Orthoptera: Pyrgomorphidae) is a wingless insect. Nombre común: chapulín, saltamontes, chocho Clase: Insecta Orden: Orthoptera Familia: Pyrgomorphidae Género: Sphenarium Especie: Sphenarium purpurascens Ch. En este video es posible ver detalles del insecto comúnmente conocido como Chapulín (Sphenarium purpurascens) con la ayuda de un microscopio. Sphenarium purpurascens purpurascens Charpentier, 1842. Nombre científico: Sphenarium purpurascens Ch. Introduction. Predominant crops (corn, bean and alfalfa) in the Puebla–Tlaxcala Valley are routinely attacked by the grasshopper Sphenarium purpurascens (Orthoptera: Pyrgomophidae). Copyright © 2007 Elsevier Ltd. All rights reserved. Egg density at the edge of farming plots was 14.9 times higher than within a plot. Counts were made on the edge and inner part of nine alfalfa plots. This research shows that manual harvest reduces the density of S. purpurascens and suggests that implementation of this mechanical method of control may be substituted for chemical control. [1] Such strategies allow decreased use of pesticide and create a source of income for farmers. The objective of this study was to evaluate the performance of a commercial strain of the entomopathogenic fungi Metarhizium acridum, on the different instars of the grasshopper pest Sphenarium purpurascens purpurascens, as well as its sporulation via bioassays under laboratory conditions, in Michoacan, Mexico. En este trabajo, se revisó el efecto de dos diferentes dietas, alfalfa y forraje de maíz, en la composición nutricional del chapulín comestible (Sphenarium purpurascens) consumido en México. 1. https://doi.org/10.1016/j.cropro.2007.08.001.

It completes one generation per year, which starts in May when eggs emerge during the rainy season (Cano-Santana, 1994).The five nymphal instars require approximately 5–6 weeks to complete development and the adult are active from 13 to 14 weeks … The number of oothecae (egg pod), eggs, eggs per ootheca and the reproductive rate (Ro) were estimated over 2 years of the study. Egg density was found to be significantly affected by control tactic, with control>manual harvest>insecticide application. A mean of 39.5 eggs/ootheca was found, which constitutes the highest recorded value for this species. Similar results were found comparing oothecae densities.

Harvesting grasshoppers Sphenarium purpurascens in Mexico for human consumption: A comparison with insecticidal control for managing pest outbreaks. Inhabitants from Central Mexico also capture the grasshoppers for sale as food. The most susceptible instars were nymphs one, two and four, with … In this study, we compared the capture of grasshoppers for human consumption to the conventional application of insecticides as a pest management strategy.

Download this stock image: Grasshopper ( Chapulin de la milpa / Sphenarium purpurascens) standing in a Prickly pear cactus in Mexico - C0B5XD from Alamy's library of millions of high resolution stock photos, illustrations and vectors. The traditional method for managing this pest in México has been the application of organophosphorus insecticides such as malathion. We propose that the manual harvest of insects is a practical method of pest control, which could be extensively applied in other crop systems in the world. Sphenarium purpurascens (Spanish: Chapulín de milpa and Portuguese: Gafanhoto-do-milho, i.e., corn-field grasshopper), is a grasshopper species in the genus Sphenarium found in Mexico and Guatemala.. Mechanical control provides general advantages: (1) a second profitable product for the human community; (2) savings realized from reduced cost of insecticides; and (3) reduced risk of soil and water contamination by insecticides.

Sphenarium purpurascens minimum Bruner, L. 1906 Ros ranged from 1.74 to 4.88 in the control, from 0.21 to 0.98 in the plots under manual harvest and from 0.38 to 0.77 in the plots under insecticide application.
