“…Persistent insect pests have not yet been established for amaranth, but lodging after the seed‐filling period in an irrigated amaranth crop in Brazil was determined to be caused by Lepidoptera larvae (Oliveira et al . ). This indicates the need for development of more targeted pest management strategies in amaranth (Torres et al .…”

The projected growth in global food demand has resulted in increased attention towards underutilized crops with the potential to improve global food security and ability to mitigate adverse effects of climate changes. Changing consumer demands in favour of more nutritiously balanced and organically grown crops have added to the interest in species such as amaranth. Promoting the consumption and cultivation of amaranth could be valuable due to its unique nutrient composition and inherent tolerance of drought and other stress factors. Due to current and predicted effects of climate changes, these attributes are becoming increasingly important. Amaranth is a source of high quality protein, as well as dietary fibre and lipids rich in unsaturated fatty acids. The seeds contain desirable levels of minerals, vitamins for human diets, in addition to other bioactive components such as phytosterols, squalene, fagopyritols, saponins and polyphenols. Amaranth is currently in demand by specific consumer groups, such as high-performance athletes, malnourished children, and people suffering from diabetes and coeliac disease. Even so, there are few detailed analyses available concerning the potential for using amaranth to improve and support agricultural productivity in developing countries. The present review has assessed the promotion and improvement of amaranth production in East Africa to hold subtstantial potential for benefitting small-holder farmers in Africa, by providing a stable source of income and food for subsistence farmers, while also mitigating the impact of climate change through the prospect of supporting the establishment of food and nutritional security.

“…Pest insects are the major factor affecting crop performance and its quality, causing losses up to 100% (Kagali et al, 2013). In Mexico, more than ten phytophagous species associated with this crop have been reported (Bautista-Martínez et al, 1997;Oliveira et al, 2012). However, there is no record of any pest insect reported in amaranth grains.…”

Objective: To identify and describe the species of lepidopteran that causes damage to amaranth grains.Design/Methodology/Approach: During six months, amaranth cereal bars were obtained to collect the larvae of the lepidopteran, a pest that consumes the grains. Larvae were kept under laboratory conditions until adults emerged. For the identification of the adults, the genitalia were extracted and photographs were taken by confocal laser scanningmicroscopy; and those of abdominal termination, egg and larvae of the first stage, by scanning electron microscopy.Results: The first report on the appearance of the flour moth Plodia interpunctella in stored amaranth grains in Mexico is presented. This is the first known record of damage to amaranth grains by this pest in the world.Study limitations/implications: In the Amaranth-producing region of Morelos, Mexico, there is no information on the pests of stored amaranth grains. Therefore, the need arises to deepen the study of the reproductive biology and ecology of Plodia interpunctella on this new host.Findings/Conclusions: The identification of Plodia interpunctella in amaranth grains will allow the development of a management strategy to prevent the spread of this new pest in the Amaranth-producing region.

“…in the Americas and elsewhere are not available. In turn, few studies concerning phytophagous insects on grain amaranth has been published in South America (Ves Losada & Covas 1987, Guerrero et al 2000, de Oliveira et al 2012, Riquelme et al 2013, which is considered the original region of two cultivable species Amaranthus cruentus and Amaranthus mantegazzianus (Sauer 1950(Sauer , 1967. Therefore, the first aim of this study was to inventory and describe the community of phytophagous insects associated to grain amaranth in Argentina, exploring the occurrence of insect guilds along the phenological cycle of the crop.…”

Amaranthus are worldwide attacked mainly by leaf chewers and sucker insects. Stem borers and leaf miners follow in importance, while minor herbivores are leaf rollers, folders, and rasping-sucking insects. The herbivorous community observed on Amaranthus spp. in Argentina was consistent with the information reported worldwide both in guild composition and order proportion. Amaranth plants had a higher number of phytophagous species in their native rather than in its introduced range. Occurrence of insect guilds differed in space and time. The highest density of leaf chewers was observed shortly after the emergence of plants, while higher density of borer and sucker insects coincided with reproductive stages of the crop. The sucking guild was observed mainly at panicles, while the insects within the leaf chewer group were registered in both leaves (92.6%, n = 746 adults) and inflorescences (7.4%). The borer guild was also recorded in stems and inflorescences; however, the density of larvae in stems was about four times as high as the density observed in panicles (n = 137 larvae).
